Linus Torvalds 3a93e40326 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
