Subject[GIT PULL] Non-x86 KVM fixes for Linux 6.3-rc5
Date
Linus,

The following changes since commit eeac8ede17557680855031c6f305ece2378af326:

Linux 6.3-rc2 (2023-03-12 16:36:44 -0700)

are available in the Git repository at:

https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus

for you to fetch changes up to 9e347ba03029e10e6405f8c3a7a91a5597943ed9:

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
