Merge tag 'pci-v7.1-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Allow TLP Processing Hints to be enabled for RCiEPs (George Abraham
P)
- Enable AtomicOps only if we know the Root Port supports them (Gerd
Bayer)
- Don't enable AtomicOps for RCiEPs since none of them need Atomic
Ops and we can't tell whether the Root Complex would support them
(Gerd Bayer)
- Leave Precision Time Measurement disabled until a driver enables it
to avoid PCIe errors (Mika Westerberg)
- Make pci_set_vga_state() fail if bridge doesn't support VGA
routing, i.e., PCI_BRIDGE_CTL_VGA is not writable, and return
errors to vga_get() callers including userspace via
/dev/vga_arbiter (Simon Richter)
- Validate max-link-speed from DT in j721e, brcmstb, mediatek-gen3,
rzg3s drivers (where the actual controller constraints are known),
and remove validation from the generic OF DT accessor (Hans Zhang)
- Remove pc110pad driver (no longer useful after 486 CPU support
removed) and no_pci_devices() (pc110pad was the last user) (Dmitry
Torokhov, Heiner Kallweit)
Resource management:
- Prevent assigning space to unimplemented bridge windows; previously
we mistakenly assumed prefetchable window existed and assigned
space and put a BAR there (Ahmed Naseef)
- Avoid shrinking bridge windows to fit in the initial Root Port
window; fixes one problem with devices with large BARs connected
via switches, e.g., Thunderbolt (Ilpo Järvinen)
- Pass full extent of empty space, not just the aligned space, to
resource_alignf callback so free space before the requested
alignment can be used (Ilpo Järvinen)
- Place small resources before larger ones for better utilization of
address space (Ilpo Järvinen)
- Fix alignment calculation for resource size larger than align,
e.g., bridge windows larger than the 1MB required alignment (Ilpo
Järvinen)
Reset:
- Update slot handling so all ARI functions are treated as being in
the same slot. They're all reset by Secondary Bus Reset, but
previously drivers of ARI functions that appeared to be on a
non-zero device weren't notified and fatal hardware errors could
result (Keith Busch)
- Make sysfs reset_subordinate hotplug safe to avoid spurious hotplug
events (Keith Busch)
- Hide Secondary Bus Reset ('bus') from sysfs reset_methods if masked
by CXL because it has no effect (Vidya Sagar)
- Avoid FLR for AMD NPU device, where it causes the device to hang
(Lizhi Hou)
Error handling:
- Clear only error bits in PCIe Device Status to avoid accidentally
clearing Emergency Power Reduction Detected (Shuai Xue)
- Check for AER errors even in devices without drivers (Lukas Wunner)
- Initialize ratelimit info so DPC and EDR paths log AER error
information (Kuppuswamy Sathyanarayanan)
Power control:
- Add UPD720201/UPD720202 USB 3.0 xHCI Host Controller .compatible so
generic pwrctrl driver can control it (Neil Armstrong)
Hotplug:
- Set LED_HW_PLUGGABLE for NPEM hotplug-capable ports so LED core
doesn't complain when setting brightness fails because the endpoint
is gone (Richard Cheng)
Peer-to-peer DMA:
- Allow wildcards in list of host bridges that support peer-to-peer
DMA between hierarchy domains and add all Google SoCs (Jacob
Moroni)
Endpoint framework:
- Advertise dynamic inbound mapping support in pci-epf-test and
update host pci_endpoint_test to skip doorbell testing if not
advertised by endpoint (Koichiro Den)
- Return 0, not remaining timeout, when MHI eDMA ops complete so
mhi_ep_ring_add_element() doesn't interpret non-zero as failure
(Daniel Hodges)
- Remove vntb and ntb duplicate resource teardown that leads to oops
when .allow_link() fails or .drop_link() is called (Koichiro Den)
- Disable vntb delayed work before clearing BAR mappings and
doorbells to avoid oops caused by doing the work after resources
have been torn down (Koichiro Den)
- Add a way to describe reserved subregions within BARs, e.g.,
platform-owned fixed register windows, and use it for the RK3588
BAR4 DMA ctrl window (Koichiro Den)
- Add BAR_DISABLED for BARs that will never be available to an EPF
driver, and change some BAR_RESERVED annotations to BAR_DISABLED
(Niklas Cassel)
- Add NTB .get_dma_dev() callback for cases where DMA API requires a
different device, e.g., vNTB devices (Koichiro Den)
- Add reserved region types for MSI-X Table and PBA so Endpoint
controllers can them as describe hardware-owned regions in a
BAR_RESERVED BAR (Manikanta Maddireddy)
- Make Tegra194/234 BAR0 programmable and remove 1MB size limit
(Manikanta Maddireddy)
- Expose Tegra BAR2 (MSI-X) and BAR4 (DMA) as 64-bit BAR_RESERVED
(Manikanta Maddireddy)
- Add Tegra194 and Tegra234 device table entries to pci_endpoint_test
(Manikanta Maddireddy)
- Skip the BAR subrange selftest if there are not enough inbound
window resources to run the test (Christian Bruel)
New native PCIe controller drivers:
- Add DT binding and driver for Andes QiLai SoC PCIe host controller
(Randolph Lin)
- Add DT binding and driver for ESWIN PCIe Root Complex (Senchuan
Zhang)
Baikal T-1 PCIe controller driver:
- Remove driver since it never quite became usable (Andy Shevchenko)
Cadence PCIe controller driver:
- Implement byte/word config reads with dword (32-bit) reads because
some Cadence controllers don't support sub-dword accesses (Aksh
Garg)
CIX Sky1 PCIe controller driver:
- Add 'power-domains' to DT binding for SCMI power domain (Gary Yang)
Freescale i.MX6 PCIe controller driver:
- Add i.MX94 and i.MX943 to fsl,imx6q-pcie-ep DT binding (Richard
Zhu)
- Delay instead of polling for L2/L3 Ready after PME_Turn_off when
suspending i.MX6SX because LTSSM registers are inaccessible
(Richard Zhu)
- Separate PERST# assertion (for resetting endpoints) from core reset
(for resetting the RC itself) to prepare for new DTs with PERST#
GPIO in per-Root Port nodes (Sherry Sun)
- Retain Root Port MSI capability on i.MX7D, i.MX8MM, and i.MX8MQ so
MSI from downstream devices will work (Richard Zhu)
- Fix i.MX95 reference clock source selection when internal refclk is
used (Franz Schnyder)
Freescale Layerscape PCIe controller driver:
- Allow building as a removable module (Sascha Hauer)
MediaTek PCIe Gen3 controller driver:
- Use dev_err_probe() to simplify error paths and make deferred probe
messages visible in /sys/kernel/debug/devices_deferred (Chen-Yu
Tsai)
- Power off device if setup fails (Chen-Yu Tsai)
- Integrate new pwrctrl API to enable power control for WiFi/BT
adapters on mainboard or in PCIe or M.2 slots (Chen-Yu Tsai)
NVIDIA Tegra194 PCIe controller driver:
- Poll less aggressively and non-atomically for PME_TO_Ack during
transition to L2 (Vidya Sagar)
- Disable LTSSM after transition to Detect on surprise link down to
stop toggling between Polling and Detect (Manikanta Maddireddy)
- Don't force the device into the D0 state before L2 when suspending
or shutting down the controller (Vidya Sagar)
- Disable PERST# IRQ only in Endpoint mode because it's not
registered in Root Port mode (Manikanta Maddireddy)
- Handle 'nvidia,refclk-select' as optional (Vidya Sagar)
- Disable direct speed change in Endpoint mode so link speed change
is controlled by the host (Vidya Sagar)
- Set LTR values before link up to avoid bogus LTR messages with 0
latency (Vidya Sagar)
- Allow system suspend when the Endpoint link is down (Vidya Sagar)
- Use DWC IP core version, not Tegra custom values, to avoid DWC core
version check warnings (Manikanta Maddireddy)
- Apply ECRC workaround to devices based on DesignWare 5.00a as well
as 4.90a (Manikanta Maddireddy)
- Disable PM Substate L1.2 in Endpoint mode to work around Tegra234
erratum (Vidya Sagar)
- Delay post-PERST# cleanup until core is powered on to avoid CBB
timeout (Manikanta Maddireddy)
- Assert CLKREQ# so switches that forward it to their downstream side
can bring up those links successfully (Vidya Sagar)
- Calibrate pipe to UPHY for Endpoint mode to reset stale PLL state
from any previous bad link state (Vidya Sagar)
- Remove IRQF_ONESHOT flag from Endpoint interrupt registration so
DMA driver and Endpoint controller driver can share the interrupt
line (Vidya Sagar)
- Enable DMA interrupt to support DMA in both Root Port and Endpoint
modes (Vidya Sagar)
- Enable hardware link retraining after link goes down in Endpoint
mode (Vidya Sagar)
- Add DT binding and driver support for core clock monitoring (Vidya
Sagar)
Qualcomm PCIe controller driver:
- Advertise 'Hot-Plug Capable' and set 'No Command Completed Support'
since Qcom Root Ports support hotplug events like DL_Up/Down and
can accept writes to Slot Control without delays between writes
(Krishna Chaitanya Chundru)
Renesas R-Car PCIe controller driver:
- Mark Endpoint BAR0 and BAR2 as Resizable (Koichiro Den)

Renesas RZ/G3S PCIe controller driver:
- Add RZ/G3E to DT binding and to driver (John Madieu)
- Assert (not deassert) resets in probe error path (John Madieu)
- Assert resets in suspend path in reverse order they were deasserted
during probe (John Madieu)

output arguments for returning drop reason where possible
- Rework drop handling within qdiscs to include more metadata about
the reason and dropping qdisc in the tracepoints

Merge tag 'gpio-updates-for-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for
controlling pins.
Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.
There's also a number of driver reworks and refactoring, documentation
updates, some bug-fixes and new tests.
GPIO core:
- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet
- unify GPIO hog handling by moving code duplicated in OF and ACPI
modules into GPIO core and allow setting up hogs with software
nodes
- allow matching GPIO controllers by secondary firmware node if
matching by primary does not succeed
- demote deferral warnings to debug level as they are quite normal
when using software nodes which don't support fw_devlink yet
- disable the legacy GPIO character device uAPI v1 supprt in Kconfig
by default
- rework several core functions in preparation for the upcoming
Revocable helper library for protecting resources against sudden
removal, this reduces the number of SRCU dereferences in GPIO core
- simplify file descriptor logic in GPIO character device code by
using FD_PREPARE()
- introduce a header defining symbols used by both GPIO consumers and
providers to avoid having to include provider-specific headers from
drivers which only consume GPIOs
- replace snprintf() with strscpy() where formatting is not required
New drivers:
- add the gpio-by-pinctrl generic driver using the ARM SCMI protocol
to control GPIOs (along with SCMI changes pulled from the pinctrl
tree)
- add a driver providing support for handling of platform events via
GPIO-signalled ACPI events (used on Intel Nova Lake and later
platforms)
Driver changes:
- extend the gpio-kempld driver with support for more recent models,
interrupts and setting/getting multiple values at once
- improve interrupt handling in gpio-brcmstb
- add support for multi-SoC systems in gpio-tegra186
- make sure we return correct values from the .get() callbacks in
several GPIO drivers by normalizing any values other than 0, 1 or
negative error numbers
- use flexible arrays in several drivers to reduce the number of
required memory allocations
- simplify synchronous waiting for virtual drivers to probe and
remove the dedicated, a bit overengineered helper library
dev-sync-probe
- remove unneeded Kconfig dependencies on OF_GPIO in several drivers
and subsystems
- convert the two remaining users of of_get_named_gpio() to using
GPIO descriptors and remove the (no longer used) function along
with the header that declares it
- add missing includes in gpio-mmio
- shrink and simplify code in gpio-max732x by using guard(mutex)
- remove duplicated code handling the 'ngpios' property from
gpio-ts4800, it's already handled in GPIO core
- use correct variable type in gpio-aspeed
- add support for a new model in gpio-realtek-otto
- allow to specify the active-low setting of simulated hogs over the
configfs interface (in addition to existing devicetree support) in
gpio-sim
Bug fixes:
- clear the OF_POPULATED flag on hog nodes in GPIO chip remove path
on OF systems
- fix resource leaks in error path in gpiochip_add_data_with_key()
- drop redundant device reference in gpio-mpsse
Tests:
- add selftests for use-after-free cases in GPIO character device
code
DT bindings:
- add a DT binding document for SCMI based, gpio-over-pinctrl devices
- fix interrupt description in microchip,mpfs-gpio
- add new compatible for gpio-realtek-otto
- describe the resets of the mpfs-gpio controller
- fix maintainer's email in gpio-delay bindings
- remove the binding document for cavium,thunder-8890 as the
corresponding device is bound over PCI and not firmware nodes
Documentation:
- update the recommended way of converting legacy boards to using
software nodes for GPIO description
- describe GPIO line value semantics
- misc updates to kerneldocs
Misc:
- convert OMAP1 ams-delta board to using GPIO hogs described with
software nodes"

Pull crypto library updates from Eric Biggers:
- Migrate more hash algorithms from the traditional crypto subsystem to
lib/crypto/
Like the algorithms migrated earlier (e.g. SHA-*), this simplifies
the implementations, improves performance, enables further
simplifications in calling code, and solves various other issues:
- AES CBC-based MACs (AES-CMAC, AES-XCBC-MAC, and AES-CBC-MAC)
- Support these algorithms in lib/crypto/ using the AES library
and the existing arm64 assembly code
- Reimplement the traditional crypto API's "cmac(aes)",
"xcbc(aes)", and "cbcmac(aes)" on top of the library
- Convert mac80211 to use the AES-CMAC library. Note: several
other subsystems can use it too and will be converted later
- Drop the broken, nonstandard, and likely unused support for
"xcbc(aes)" with key lengths other than 128 bits
- Enable optimizations by default
- GHASH
- Migrate the standalone GHASH code into lib/crypto/
- Integrate the GHASH code more closely with the very similar
POLYVAL code, and improve the generic GHASH implementation to
resist cache-timing attacks and use much less memory
- Reimplement the AES-GCM library and the "gcm" crypto_aead
template on top of the GHASH library. Remove "ghash" from the
crypto_shash API, as it's no longer needed
- Enable optimizations by default
- SM3
- Migrate the kernel's existing SM3 code into lib/crypto/, and
reimplement the traditional crypto API's "sm3" on top of it
- I don't recommend using SM3, but this cleanup is worthwhile
to organize the code the same way as other algorithms
- Testing improvements:
- Add a KUnit test suite for each of the new library APIs
- Migrate the existing ChaCha20Poly1305 test to KUnit
- Make the KUnit all_tests.config enable all crypto library tests
- Move the test kconfig options to the Runtime Testing menu
- Other updates to arch-optimized crypto code:
- Optimize SHA-256 for Zhaoxin CPUs using the Padlock Hash Engine
- Remove some MD5 implementations that are no longer worth keeping
- Drop big endian and voluntary preemption support from the arm64
code, as those configurations are no longer supported on arm64
- Make jitterentropy and samples/tsm-mr use the crypto library APIs

Merge branch 'nocache-cleanup'
This series cleans up some of the special user copy functions naming and semantics. In particular, get rid of the (very traditional) double underscore names and behavior: the whole "optimize away the range check" model has been largely excised from the other user accessors because it's so subtle and can be unsafe, but also because it's just not a relevant optimization any more. To do that, a couple of drivers that misused the "user" copies as kernel copies in order to get non-temporal stores had to be fixed up, but that kind of code should never have been allowed anyway. The x86-only "nocache" version was also renamed to more accurately reflect what it actually does. This was all done because I looked at this code due to a report by Jann Horn, and I just couldn't stand the inconsistent naming, the horrible semantics, and the random misuse of these functions. This code should probably be cleaned up further, but it's at least slightly closer to normal semantics. I had a more intrusive series that went even further in trying to normalize the semantics, but that ended up hitting so many other inconsistencies between different architectures in this area (eg 'size_t' vs 'unsigned long' vs 'int' as size arguments, and various iovec check differences that Vasily Gorbik pointed out) that I ended up with this more limited version that fixed the worst of the issues.

Remove the "michael_mic" crypto_shash algorithm, since it's no longer used. Its only users were wireless drivers, which have now been converted to use the michael_mic() function instead. It makes sense that no other users ever appeared: Michael MIC is an insecure algorithm that is specific to WPA TKIP, which itself was an interim security solution to replace the broken WEP standard.

mm: convert do_brk_flags() to use vma_flags_t
In order to be able to do this, we need to change VM_DATA_DEFAULT_FLAGS and friends and update the architecture-specific definitions also. We then have to update some KSM logic to handle VMA flags, and introduce VMA_STACK_FLAGS to define the vma_flags_t equivalent of VM_STACK_FLAGS. We also introduce two helper functions for use during the time we are converting legacy flags to vma_flags_t values - vma_flags_to_legacy() and legacy_to_vma_flags(). This enables us to iteratively make changes to break these changes up into separate parts. We use these explicitly here to keep VM_STACK_FLAGS around for certain users which need to maintain the legacy vm_flags_t values for the time being. We are no longer able to rely on the simple VM_xxx being set to zero if the feature is not enabled, so in the case of VM_DROPPABLE we introduce VMA_DROPPABLE as the vma_flags_t equivalent, which is set to EMPTY_VMA_FLAGS if the droppable flag is not available. While we're here, we make the description of do_brk_flags() into a kdoc comment, as it almost was already. We use vma_flags_to_legacy() to not need to update the vm_get_page_prot() logic as this time. Note that in create_init_stack_vma() we have to replace the BUILD_BUG_ON() with a VM_WARN_ON_ONCE() as the tested values are no longer build time available. We also update mprotect_fixup() to use VMA flags where possible, though we have to live with a little duplication between vm_flags_t and vma_flags_t values for the time being until further conversions are made. While we're here, update VM_SPECIAL to be defined in terms of VMA_SPECIAL_FLAGS now we have vma_flags_to_legacy(). Finally, we update the VMA tests to reflect these changes.

Patch series "change young flag check functions to return bool", v2. This is a cleanup patchset to change all young flag check functions to return bool, as discussed with David in the previous thread[1]. Since callers only care about whether the young flag was set, returning bool makes the intention clearer. No functional changes intended. This patch (of 6): Callers use ptep_test_and_clear_young() to clear the young flag and check whether it was set. Change the return type to bool to make the intention clearer.

mm: remove CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE
Patch series "mm: remove CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE and cleanup CONFIG_MIGRATION". While working on memory hotplug code cleanups, I realized that CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE is not really required anymore. Changing that revealed some rather nasty looking CONFIG_MIGRATION handling. Let's clean that up by introducing a dedicated CONFIG_NUMA_MIGRATION option and reducing the dependencies that CONFIG_MIGRATION has. This patch (of 2): All architectures that select CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE also select CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG. So we can just remove CONFIG_ARCH_ENABLE_MEMORY_HOTREMOVE. For CONFIG_MIGRATION, make it depend on CONFIG_MEMORY_HOTREMOVE instead, and make CONFIG_MEMORY_HOTREMOVE select CONFIG_MIGRATION (just like CONFIG_CMA and CONFIG_COMPACTION already do). We'll clean up CONFIG_MIGRATION next.

arch, mm: consolidate empty_zero_page
Reduce 22 declarations of empty_zero_page to 3 and 23 declarations of ZERO_PAGE() to 4. Every architecture defines empty_zero_page that way or another, but for the most of them it is always a page aligned page in BSS and most definitions of ZERO_PAGE do virt_to_page(empty_zero_page). Move Linus vetted x86 definition of empty_zero_page and ZERO_PAGE() to the core MM and drop these definitions in architectures that do not implement colored zero page (MIPS and s390). ZERO_PAGE() remains a macro because turning it to a wrapper for a static inline causes severe pain in header dependencies. For the most part the change is mechanical, with these being noteworthy: * alpha: aliased empty_zero_page with ZERO_PGE that was also used for boot parameters. Switching to a generic empty_zero_page removes the aliasing and keeps ZERO_PGE for boot parameters only * arm64: uses __pa_symbol() in ZERO_PAGE() so that definition of ZERO_PAGE() is kept intact. * m68k/parisc/um: allocated empty_zero_page from memblock, although they do not support zero page coloring and having it in BSS will work fine. * sparc64 can have empty_zero_page in BSS rather allocate it, but it can't use virt_to_page() for BSS. Keep it's definition of ZERO_PAGE() but instead of allocating it, make mem_map_zero point to empty_zero_page. * sh: used empty_zero_page for boot parameters at the very early boot. Rename the parameters page to boot_params_page and let sh use the generic empty_zero_page. * hexagon: had an amusing comment about empty_zero_page /* A handy thing to have if one has the RAM. Declared in head.S */ that unfortunately had to go :) Link: https://lkml.kernel.org/r/20260211103141.3215197-4-rppt@kernel.org Signed-off-by: Mike Rapoport (Microsoft) <rppt@kernel.org> Acked-by: Helge Deller <deller@gmx.de> [parisc] Tested-by: Helge Deller <deller@gmx.de> [parisc] Reviewed-by: Christophe Leroy (CS GROUP) <chleroy@kernel.org> Acked-by: Dave Hansen <dave.hansen@linux.intel.com> Acked-by: Catalin Marinas <catalin.marinas@arm.com> Acked-by: Magnus Lindholm <linmag7@gmail.com> [alpha] Acked-by: Dinh Nguyen <dinguyen@kernel.org> [nios2] Acked-by: Andreas Larsson <andreas@gaisler.com> [sparc] Acked-by: David Hildenbrand (Arm) <david@kernel.org> Acked-by: Liam R.

powerpc64/bpf: Add support for indirect jump
Add support for a new instruction BPF_JMP|BPF_X|BPF_JA, SRC=0, DST=Rx, off=0, imm=0 which does an indirect jump to a location stored in Rx. The register Rx should have type PTR_TO_INSN. This new type ensures that the Rx register contains a value (or a range of values) loaded from a correct jump table – map of type instruction array. Support indirect jump to all registers in powerpc64 JIT using the ctr register. Move Rx content to ctr register, then invoke bctr instruction to branch to address stored in ctr register. Skip save and restore of TOC as the jump is always within the program context.

powerpc/bpf: Add support for instruction array
On loading the BPF program, the verifier might adjust/omit some
instructions. The adjusted instruction offset is accounted in the
map containing original instruction -> xlated mapping. This patch
add ppc64 JIT support to additionally build the xlated->jitted
mapping for every instruction present in instruction array. This
change is needed to enable support for indirect jumps, added in a
subsequent patch.
Invoke bpf_prog_update_insn_ptrs() with offset pair of xlated_offset
and jited_offset. The offset mapping is already available, which is
being used for bpf_prog_fill_jited_linfo() and can be directly used
for bpf_prog_update_insn_ptrs() as well.

powerpc64/bpf: Implement JIT support for private stack
Provision the private stack as a per-CPU allocation during
bpf_int_jit_compile(). Align the stack to 16 bytes and place guard
regions at both ends to detect runtime stack overflow and underflow.
Round the private stack size up to the nearest 16-byte boundary.
Make each guard region 16 bytes to preserve the required overall
16-byte alignment. When private stack is set, skip bpf stack size
accounting in kernel stack.
There is no stack pointer in powerpc. Stack referencing during JIT
is done using frame pointer. Frame pointer calculation goes like:
BPF frame pointer = Priv stack allocation start address +
Overflow guard +
Actual stack size defined by verifier
Memory layout:
High Addr +--------------------------------------------------+
| |
| 16 bytes Underflow guard (0xEB9F12345678eb9fULL) |
| |
BPF FP -> +--------------------------------------------------+
| |
| Private stack - determined by verifier |
| 16-bytes aligned |

+--------------------------------------------------+
| |
Lower Addr | 16 byte Overflow guard (0xEB9F12345678eb9fULL) |

Update BPF_REG_FP to point to the calculated offset within the
allocated private stack buffer. Now, BPF stack usage reference

powerpc: pci-ioda: Optimize pnv_ioda_pick_m64_pe()
bitmap_empty() in pnv_ioda_pick_m64_pe() is O(N) and useless because the following find_next_bit() does the same work. Drop it, and while there replace a while() loop with the dedicated for_each_set_bit().

powerpc: pci-ioda: use bitmap_alloc() in pnv_ioda_pick_m64_pe()
Use the dedicated bitmap_alloc() in pnv_ioda_pick_m64_pe() and drop some housekeeping code. Because pe_alloc is local, annotate it with __free() and get rid of the explicit kfree() calls.

powerpc: Move GameCube/Wii options under EMBEDDED6xx

powerpc/44x/uic: Consolidate chained IRQ handler install/remove
The driver currently sets the handler data and the chained handler in two separate steps. This creates a theoretical race window where an interrupt could fire after the handler is set but before the data is assigned, leading to a NULL pointer dereference. Replace the two calls with irq_set_chained_handler_and_data() to set both the handler and its data atomically under the irq_desc->lock.
