a563d780c1 munmap: fix deadlock with remote pagefault on vm range lock 
Add similar protection to clear_host_pte than to set_host_vma (see #986)

Also make the page fault handler only skip taking lock if the munmap
happened on the same cpu id

edd3ea0103 Revert "memory_range_lock: Enable interrupt when trylock fails" 
This reverts commit 0d3ef65092.

Reason for revert: This fix causes circular dependency with memory_range manipulation and TLB flush. See #1394.

ba80dd8650 arm64: Fix for ptrace instruction rewrite on thunder-x2. 
- Fixed the problem that instruction rewriting by PTRACE_POKETEXT is not reflected.
   The cause is that the instruction cache was not flushed.

 - Add instruction chache flush in ptrace_report_signal().

10cca81401 arm64 vdso warning: fix non-void function not returning 
arch_setup_vdso() needs to return something even on panic to please gcc.
In theory, flagging panic() with __attribute__((noreturn)) should work
just the same and is a much better solution but for some reason on older
gcc versions setting the flag leads to the weak memset() symbol not
being found !?
