Merge tag 'kvm-riscv-fixes-6.3-1' of https://github.com/kvm-riscv/linux into HEAD (2023-03-27 10:04:07 -0400)
There are also some pending x86 changes will come later this week.
----------------------------------------------------------------
RISC-V:
* Fix VM hang in case of timer delta being zero
ARM:
* Fixes for the MMU:
* Read the MMU notifier seq before dropping the mmap lock to guard
against reading a potentially stale VMA
* Disable interrupts when walking user page tables to protect against
the page table being freed
* Read the MTE permissions for the VMA within the mmap lock critical
section, avoiding the use of a potentally stale VMA pointer
* Fixes for the vPMU:
* Return the sum of the current perf event value and PMC snapshot for
reads from userspace
* Don't save the value of guest writes to PMCR_EL0.{C,P}, which could
otherwise lead to userspace erroneously resetting the vPMU during VM
save/restore
