When pKVM is enabled, the hypervisor code at EL2 and its data structures
are inaccessible to the host kernel and cannot be torn down or replaced
as this would defeat the integrity properies which pKVM aims to provide.
Furthermore, the ABI between the host and EL2 is flexible and private to
whatever the current implementation of KVM requires and so booting a new
kernel with an old EL2 component is very likely to end in disaster.
In preparation for uninstalling the hyp stub calls which are relied upon
to reset EL2, disable kexec and hibernation in the host when protected
KVM is enabled.

__KVM_HOST_SMCCC_FUNC_* is a royal pain, as there is a fair amount
of churn around these #defines, and we avoid making it an enum
only for the sake of the early init, low level code that requires
__KVM_HOST_SMCCC_FUNC___kvm_hyp_init to be usable from assembly.
Let's be brave and turn everything but this symbol into an enum,
using a bit of arithmetic to avoid any overlap.

Couple of fixes addressing issues when FFA driver is build as a module.
One adds the device unregistration which was missing and causes issue
when loading the module second time after unloading once. Another one
adds the missing remove callback on the ffa bus which was missing due
to which modules depending on FFA(e.g. OPTEE) will fail to remove the
device and faults next time that module is loaded again.

kzalloc() is used to allocate memory for cd->detectors, and if it fails,
channel_detector_exit() behind the label fail will be called:
channel_detector_exit(dpd, cd);
In channel_detector_exit(), cd->detectors is dereferenced through:
struct pri_detector *de = cd->detectors[i];
To fix this possible null-pointer dereference, check cd->detectors before
the for loop to dereference cd->detectors.

The problem is that "channel" is an unsigned int, when it's less 5 the
value of "channel - 5" is not a negative number as one would expect but
is very high positive value instead.
This means that "start" becomes a very high positive value. The result
of that is that we never enter the "for (i = start; i <= end; i++) {"
loop. Instead of storing the result from b43legacy_radio_aci_detect()
it just uses zero.

The command ring pointer is located at [6:63] bits of the command
ring control register (CRCR). All the control bits like command stop,
abort are located at [0:3] bits. While aborting a command, we read the
CRCR and set the abort bit and write to the CRCR. The read will always
give command ring pointer as all zeros. So we essentially write only
the control bits. Since we split the 64 bit write into two 32 bit writes,
there is a possibility of xHC command ring stopped before the upper
dword (all zeros) is written. If that happens, xHC updates the upper
dword of its internal command ring pointer with all zeros. Next time,
when the command ring is restarted, we see xHC memory access failures.
Fix this issue by only writing to the lower dword of CRCR where all
control bits are located.

Seen on a VLI VL805 PCIe to USB controller. For non-stream endpoints
at least, if the xHC halts on a particular TRB due to an error then
the DCS field in the Out Endpoint Context maintained by the hardware
is not updated with the current cycle state.
Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit
from the TRB that the xHC stopped on.

The kernel already has support for very similar Pioneer djm products
and this work is based on that.
Added device to quirks-table.h and added control info to
mixer_quirks.c.
Tested on my hardware and all working.

Fix a regression hit by the IPR SCSI driver, introduced by the recent addition of MSI
domains on pseries.
A big series including 8 BPF fixes, some with potential security impact and the rest
various code generation issues.
Fix our program check assembler entry path, which was accidentally jumping into a gas
macro and generating strange stack frames, which could confuse find_bug().
A couple of fixes, and related changes, to fix corner cases in our machine check handling.
Fix our DMA IOMMU ops, which were not always returning the optimal DMA mask, leading to
at least one device falling back to 32-bit DMA when it shouldn't.
A fix for KUAP handling on 32-bit Book3S.
Fix crashes seen when kdumping on some pseries systems.

if CONFIG_ACPI=n, the ID table left unused which is not what we want.
Instead of adding ifdeffery here and there, drop ACPI_PTR().

Having "_USI" suffix in EXYNOS_COMMON_SERIAL_DRV_DATA_USI() macro is
confusing. Rename it to just EXYNOS_COMMON_SERIAL_DRV_DATA() and provide
USI registers availability for all Exynos variants instead. While at it,
also convert .has_usi field type to bool, so its usage is more obvious.
