Ard Biesheuvel f83b4f8860 arm64/kprobes: set VM_FLUSH_RESET_PERMS on kprobe instruction pages 
In order to avoid transient inconsistencies where freed code pages
are remapped writable while stale TLB entries still exist on other
cores, mark the kprobes text pages with the VM_FLUSH_RESET_PERMS
attribute. This instructs the core vmalloc code not to defer the
TLB flush when this region is unmapped and returned to the page
allocator.
