Pull amr64 kvm fix from Will Deacon:
"We've uncovered a nasty bug in the arm64 KVM code which allows a badly
behaved 32-bit guest to bring down the host. The fix is simple (it's
what I believe we call a "brown paper bag" bug) and I don't think it
makes sense to sit on this, particularly as Russell ended up
triggering this rather than just somebody noticing a potential problem
by inspection.
Usually arm64 KVM changes would go via Paolo's tree, but he's on
holiday at the moment and the deal is that anything urgent gets
shuffled via the arch trees, so here it is.
Summary:
Fix arm64 KVM issue when injecting an abort into a 32-bit guest, which
would lead to an illegal exception return at EL2 and a subsequent host
crash"
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: KVM: Fix host crash when injecting a fault into a 32bit guest
Issue: When the disks are getting discovered and assigned device
handles by the kernel, a device block followed by an unblock
(due to broadcast primitives) issued by the driver is
interspersed by the kernel changing the state of the device.
Therefore the unblock by the driver results in a no operation
within the kernel API.
To fix this one, the below patch checks the return of the unblock API
and performs a block followed by an unblock to unfreeze the block
layer's I/O queue. Sufficient checks and prints are also added in the
driver to identify this condition caused by the kernel.

For any SCSI command, if the driver receives
IOC status = SCSI_IOC_TERMINATED and log info = 0x32010081 then
that command will be completed with DID_RESET host status.
The definition of this log info value is
"Virtual IO has failed and has to be retried".
Firmware will provide this log info value with IOC Status
"SCSI_IOC_TERMINATED", whenever a drive (with is a part of a volume)
is pulled and pushed back within some minimal delay.
With this log info value, firmware informs the driver to retry the
failed IO command infinite times, so to provide some time for the
firmware to discover the reinserted drive successfully instated of
just retrying failed command for five times(doesn't giving enough
time for firmware to complete the drive discovery) and failing the
IO permanently even though drive came back successfully.

- When end device is added in the topology,
- When the end device is removed from the setup,
- When the SCSI mid layer issues TASK ABORT/ DEVICE RESET/ TARGET RESET during

- When any command to the device fails with Sense key Hardware error or Medium

- When firmware returns device error or device not ready status for the end

During hot-plugging of a disk(having a flaky link), the disk addition
stops and any further disk addition or removal doesn't happen on that
controller.
This is because, when driver receives DELAY_NOT_RESPONDING event for a disk
while it is undergoing addition at the SCSI Transport layer, the driver
would block the I/O to that disk resulting in a deadlock. i.e the disk
addition work couldn't be completed at the SCSI Transport Layer as it
can't send any I/Os (such as Inquiry, Report LUNs etc) to the disk as
I/Os are blocked to this drive. Also any subsequent device removal
(TARGET_NOT_RESPONDING) or link update(RC_PHY_CHANGED) event couldn't be
processed as they are in the queue to get processed after disk addition
event.
Description of Change:
Don't block the drive when drive addition is under the control of SML.
So that SML won't be blocked of issuing the device dicovery commands
(such as Inquiry, Report LUNs etc).

up-to 96.
Following are changes that are done in this patch
1. This feature is enabled only for SAS3 C0 and higher revision cards and also
only when reply post free queue count is greater than 8.
2. To support this feature 12 SupplementalReplyPostHostIndex system interfaces
are used. MSI-X index numbered from 0 to 7 use the first
SupplementalReplyPostHostIndex system interface to update its corresponding
ReplyPostHostIndex values, MSI-X index numbered from 8 to 15 will use the
second SupplementalReplyPostHostIndex system interface and so on. These 12
SuppementalReplyPostHostIndex system interfaces address are saved in the array
replyPostRegisterIndex[].
3. As each SupplementalReplyPostHostIndex register supports 8 MSI-X
vectors. So MSIxIndex field in these register must contain a value between 0
and 7.
4. After processing the reply descriptors from a reply post free queues then
update the new reply post host index value in ReplyPostHostIndex field and
(msix_index mod 8) value in MSIxIndex field of SupplementalReplyPostHostIndex
register. The Address of this SupplementalReplyPostHostIndex register is
retrived from (msix_index/8)th entry of replyPostRegisterIndex[] array.

When injecting a fault into a misbehaving 32bit guest, it seems
rather idiotic to also inject a 64bit fault that is only going
to corrupt the guest state. This leads to a situation where we
perform an illegal exception return at EL2 causing the host
to crash instead of killing the guest.
Just fix the stupid bug that has been there from day 1.

So far, GICv2 has been used with EOImode == 0. The effect of this
mode is to perform the priority drop and the deactivation of the
interrupt at the same time.
While this works perfectly for Linux (we only have a single priority),
it causes issues when an interrupt is forwarded to a guest, and when
we want the guest to perform the EOI itself.
For this case, the GIC architecture provides EOImode == 1, where:
- A write to the EOI register drops the priority of the interrupt
and leaves it active. Other interrupts at the same priority level
can now be taken, but the active interrupt cannot be taken again
- A write to the DIR marks the interrupt as inactive, meaning it can
now be taken again.
We only enable this feature when booted in HYP mode and that
the device-tree reported a suitable CPU interface. Observable behaviour
should remain unchanged.
