Dan reports that smatch complains about a potential uninitialized
variable being used in the compat alignment fixup code.
The logic is not wrong per se, but we do end up using an uninitialized
variable if reading the instruction that triggered the alignment fault
from user space faults, even if the fault ensures that the uninitialized
value doesn't propagate any further.
Given that we just give up and return 1 if any fault occurs when reading
the instruction, let's get rid of the 'success handling' pattern that
captures the fault in a variable and aborts later, and instead, just
return 1 immediately if any of the get_user() calls result in an
exception.

initialized to 0, but never set. To advertise CSV2/3 to protected
guests, pass the CSV2/3 values to hyp when initializing hyp's
view of guests' ID_AA64PFR0_EL1.
Similar to non-protected KVM, these are system-wide, rather than
per cpu, for simplicity.

When BPF_TRAMP_F_CALL_ORIG is set, BPF trampoline uses BLR to jump
back to the instruction next to call site to call the patched function.
For BTI-enabled kernel, the instruction next to call site is usually
PACIASP, in this case, it's safe to jump back with BLR. But when
the call site is not followed by a PACIASP or bti, a BTI exception
is triggered.
Here is a fault log:

When introduced, IRQFD resampling worked on POWER8 with XICS. However
KVM on POWER9 has never implemented it - the compatibility mode code
("XICS-on-XIVE") misses the kvm_notify_acked_irq() call and the native
XIVE mode does not handle INTx in KVM at all.
This moved the capability support advertising to platforms and stops
advertising it on XIVE, i.e. POWER9 and later.

Merge tag 'kvm-s390-master-6.3-1' of https://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into HEAD
A small fix that repairs the external loop detection code for PV
guests.
Currently, with VHE, KVM enables the EL0 event counting for the
guest on vcpu_load() or KVM enables it as a part of the PMU
register emulation process, when needed. However, in the migration
case (with VHE), the same handling is lacking, as vPMU register
values that were restored by userspace haven't been propagated yet
(the PMU events haven't been created) at the vcpu load-time on the
first KVM_RUN (kvm_vcpu_pmu_restore_guest() called from vcpu_load()
on the first KVM_RUN won't do anything as events_{guest,host} of
kvm_pmu_events are still zero).
So, with VHE, enable the guest's EL0 event counting on the first
KVM_RUN (after the migration) when needed. More specifically,
have kvm_pmu_handle_pmcr() call kvm_vcpu_pmu_restore_guest()
so that kvm_pmu_handle_pmcr() on the first KVM_RUN can take
care of it.

This correct SIM card selection on the two newly introduced
MSM8916-based USB modems.
The firmware-name for the first CDSP is corrected on the SA8540P Ride
board.
The PCIe controller in SC7280 is marked cache-coherent, which resolves
seen data corruption issues.
Labels are added to the vadc channel nodes on SC8280XP, as the Linux
driver was updated to not include the unit address when generating
device names and collisions thereby prevented registration of the
channels. Audio clocks and routing is corrected and a few regulators are
marked always-on for the Lenovo Thinkpad X13s, as their clients are not
fully described at this point.
SPI5 was accidentally enabled by default on SM6115, and is disabled
again.
CDSP on SM6375 is provided its power-domains, to appropriately vote for
during power up for the DSP.
The iommu mask for the PCIe controllers in SM8150 is updated, to match
what the hypervisor expects.
Th Venus firmware path is corrected on Xiaomi Mi Pad 5 Pro.
The UFS controller is marked cache coherent on SM8350 and SM8450.
The clocks for the second WSA macro on SM8450 is corrected, and given
its own clocks.
The bias-pull-up value for I2C pins are corrected on SM8550, to trigger
the selection of the strong pull. CPU compatibles and the base address
of the LPASS TLMM block are corrected.

On page fault, we find about the VMA that backs the page fault
early on, and quickly release the mmap_read_lock. However, using
the VMA pointer after the critical section is pretty dangerous,
as a teardown may happen in the meantime and the VMA be long gone.
Move the sampling of the MTE permission early, and NULL-ify the
VMA pointer after that, just to be on the safe side.

We walk the userspace PTs to discover what mapping size was
used there. However, this can race against the userspace tables
being freed, and we end-up in the weeds.
Thankfully, the mm code is being generous and will IPI us when
doing so. So let's implement our part of the bargain and disable
interrupts around the walk. This ensures that nothing terrible
happens during that time.
We still need to handle the removal of the page tables before
the walk. For that, allow get_user_mapping_size() to return an
error, and make sure this error can be propagated all the way
to the the exit handler.

Read mmu_invalidate_seq before dropping the mmap_lock so that KVM can
detect if the results of vma_lookup() (e.g. vma_shift) become stale
before it acquires kvm->mmu_lock. This fixes a theoretical bug where a
VMA could be changed by userspace after vma_lookup() and before KVM
reads the mmu_invalidate_seq, causing KVM to install page table entries
based on a (possibly) no-longer-valid vma_shift.
Re-order the MMU cache top-up to earlier in user_mem_abort() so that it
is not done after KVM has read mmu_invalidate_seq (i.e. so as to avoid
inducing spurious fault retries).
This bug has existed since KVM/ARM's inception. It's unlikely that any
sane userspace currently modifies VMAs in such a way as to trigger this
race. And even with directed testing I was unable to reproduce it. But a
sufficiently motivated host userspace might be able to exploit this
race.

Presently, when a guest writes 1 to PMCR_EL0.{C,P}, which is WO/RAZ,
KVM saves the register value, including these bits.
When userspace reads the register using KVM_GET_ONE_REG, KVM returns
the saved register value as it is (the saved value might have these
bits set). This could result in userspace setting these bits on the
destination during migration. Consequently, KVM may end up resetting
the vPMU counter registers (PMCCNTR_EL0 and/or PMEVCNTR<n>_EL0) to
zero on the first KVM_RUN after migration.
Fix this by not saving those bits when a guest writes 1 to those bits.

Have KVM_GET_ONE_REG for vPMU counter (vPMC) registers (PMCCNTR_EL0
and PMEVCNTR<n>_EL0) return the sum of the register value in the sysreg
file and the current perf event counter value.
Values of vPMC registers are saved in sysreg files on certain occasions.
These saved values don't represent the current values of the vPMC
registers if the perf events for the vPMCs count events after the save.
The current values of those registers are the sum of the sysreg file
value and the current perf event counter value. But, when userspace
reads those registers (using KVM_GET_ONE_REG), KVM returns the sysreg
file value to userspace (not the sum value).
Fix this to return the sum value for KVM_GET_ONE_REG.

Having a per-vcpu virtual offset is a pain. It needs to be synchronized
on each update, and expands badly to a setup where different timers can
have different offsets, or have composite offsets (as with NV).
So let's start by replacing the use of the CNTVOFF_EL2 shadow register
(which we want to reclaim for NV anyway), and make the virtual timer
carry a pointer to a VM-wide offset.
This simplifies the code significantly. It also addresses two terrible bugs:
- The use of CNTVOFF_EL2 leads to some nice offset corruption
when the sysreg gets reset, as reported by Joey.
- The kvm mutex is taken from a vcpu ioctl, which goes against
the locking rules...

The PE/COFF header has a NX compat flag which informs the firmware that
the application does not rely on memory regions being mapped with both
executable and writable permissions at the same time.
This is typically used by the firmware to decide whether it can set the
NX attribute on all allocations it returns, but going forward, it may be
used to enforce a policy that only permits applications with the NX flag
set to be loaded to begin wiht in some configurations, e.g., when Secure
Boot is in effect.
Even though the arm64 version of the EFI stub may relocate the kernel
before executing it, it always did so after disabling the MMU, and so we
were always in line with what the NX compat flag conveys, we just never
bothered to set it.
So let's set the flag now.

The second LPASS pin controller IO address is supposed to be the MCC
range which contains the slew rate registers. The Linux driver then
accesses slew rate register with hard-coded offset (0xa000). However
the DTS contained the address of slew rate register as the second IO
address, thus any reads were effectively pass the memory space and lead
to "Internal error: synchronous external aborts" when applying pin
