Merge tag 'kvmarm-fixes-7.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 fixes for 7.1, take #2
- Add the pKVM side of the workaround for ARM's erratum 4193714, provided
that the EL3 firmware does its part of the job. KVM will refuse to
initialise otherwise.
- Correctly handle 52bit VAs for guest EL2 stage-1 translations when
running under NV with E2H==0.
- Correctly deal with permission faults in guest_memfd memslots.
- Fix the steal-time selftest after the infrastructure was reworked.
- Make sure the host cannot pass a non-sensical clock update to the
EL2 tracing infrastructure.
- Appoint Steffen Eiden as a reviewer in anticipation of the KVM/s390
ability to run arm64 guests, which will inevitably lead to arm64
code being directly used on s390.
- Make sure that EL2 is configured with both exception entry and exit
being Context Synchronization Events.
- Handle the current vcpu being NULL on EL2 panic.
- Fix the selftest_vcpu memcache being empty at the point of donation or
sharing.
- Check that the memcache has enough capacity before engaging on the
share/donate path.
- Fix __deactivate_fgt() to use its parameter rather than a variable
in the macro context.
