The kernel memtest utility is incredibly useful for detecting memory
problems, but sadly isn't in defconfig.
The memtest itself is only run when the user has explicitly passed a
memtest option on the kernel command line, so simply enabling the option
should not have a negative impact.

section 6.2.17 _CCA states that ARM platforms require ACPI _CCA
object to be specified for DMA-cabpable devices. Therefore, this patch
specifies ACPI_CCA_REQUIRED in arm64 Kconfig.
In addition, to handle the case when _CCA is missing, arm64 would assign
dummy_dma_ops to disable DMA capability of the device.

The '__init aesni_init()' function calls the '__exit crypto_fpu_exit()'
function directly. Since they are in different sections, this generates
a warning.
make CONFIG_DEBUG_SECTION_MISMATCH=y
...
WARNING: arch/x86/crypto/aesni-intel.o(.init.text+0x12b): Section
mismatch in reference from the function init_module() to the function
.exit.text:crypto_fpu_exit()
The function __init init_module() references
a function __exit crypto_fpu_exit().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
crypto_fpu_exit() so it may be used outside an exit section.

Pull more MIPS fixes from Ralf Baechle:
"Another round of 4.1 MIPS fixes, one fix to a MIPS-specific #if
condition in lib/mpi, one fix to the MIPS GIC irqchip driver and one
SSB fix.
Details:
- fix handling of clock in chipco SSB driver.
- fix two MIPS-specific #if conditions to correctly work for GCC 5.1.
- fix damage to R6 pgtable bits done by XPA support.
- fix possible crash due to unloading modules that contain statically
defined platform devices.
- fix disabling of the MSA ASE on context switch to also work
correctly when a new thread/process has the CPU for the very first

In Thumb2 mode, the stack register r13 is deprecated if the
destination register is the program counter (r15). Similar to
head.S, head-nommu.S uses r13 to store the return address used
after configuring the CPU's CP15 register. However, since we do
not enable a MMU, there will be no address switch and it is
possible to use branch with link instruction to call
__after_proc_init.
Avoid using r13 completely by using bl to call __after_proc_init
and get rid of __secondary_switched.
Beside removing unnecessary complexity, this also fixes a
compiler warning when compiling a !MMU kernel:
Warning: Use of r13 as a source register is deprecated when r15
is the destination register.

Some platforms always enter the kernel in the ARM state even if
the kernel is compiled for THUMB2. Add a small wrapper on top of
cpu_resume() that switches into THUMB2 state.
This provides the functionality to fix a problem reported by Kevin
Hilman on next-20150601 where the ifc6410 fails to boot a THUMB2
kernel because the platform's firmware always enters the kernel in
ARM mode from deep idle states.

So far, we configured the world-switch by having a small array
of pointers to the save and restore functions, depending on the
GIC used on the platform.
Loading these values each time is a bit silly (they never change),
and it makes sense to rely on the instruction patching instead.

This is, of course, bogus because 0x00007fffffffccbf is *within*

went looking at it. But I eventually realized that I was
getting a '0' offset back from xstate_offsets[BNDREGS].
It was being skipped in the initialization, which is obviously
bogus, so remove the extra leaf++.

Omap hwmod changes for v4.2 via Paul Walmsley <paul@pwsan.com>:
Several OMAP2+ hwmod changes for v4.2. One patch cleans up a nasty
interaction between the OMAP GPMC and the hwmod code when debugging is
enabled. IP block integration data has been added for the AM43xx EMIF
RAM controller. There's also a fix for the omap-aes driver when used in
QEMU. And finally, some changes to the OMAP3 hwmod code to support the
use of the security IP blocks (AES and SHA) on GP devices, or when they've
specifically been enabled in the DT data.

Now FPSIMD don't handle HOTPLUG_CPU. This introduces bug after cpu down/up process.
After cpu down/up process, the FPSMID hardware register is default value, not any
process's fpsimd context. when CPU_DEAD set cpu's fpsimd_state to NULL, it will force
to load the fpsimd context for the thread, to avoid the chance to skip to load the context.
If process A is the last user process on CPU N before cpu down, and the first user process
on the same CPU N after cpu up, A's fpsimd_state.cpu is the current cpu id,
and per_cpu(fpsimd_last_state) points A's fpsimd_state, so kernel will not reload the
context during it return to user space.
