# Merge: 91fe204578ba 9e347ba03029
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     
#     Pull kvm fixes from Paolo Bonzini:
#      "RISC-V:
#     
#        - Fix VM hang in case of timer delta being zero
#     
#      ARM:
#     
#        - MMU fixes:
#     
#           - 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
#     
#        - vPMU fixes:
#     
#           - 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"
