with some missed aarch64 v5.8 bits.
i noticed that v5.2 had new syscalls with new macros defined
in linux/mount.h, but since those syscalls are undocumented
(open_tree, move_mount, fsopen, fsconfig, fsmount and fspick)
i think it's fine to leave those macros out but the new flag
for mount is added.
Szabolcs Nagy (11):
bits/syscall.h: add process_madvise from linux v5.10
sys/membarrier.h: add new constants from linux v5.10
sys/mount.h: add MS_NOSYMFOLLOW from linux v5.10
sys/mman.h: add MAP_HUGE_16KB from linux v5.10
elf.h: add NT_ARM_TAGGED_ADDR_CTRL from linux v5.10
sys/prctl.h: add MTE related constants from linux v5.10
signal.h: add MTE specific SIGSEGV codes from linux v5.10
aarch64/bits/hwcap.h: add HWCAP2_BTI from linux v5.8
add aarch64/bits/mman.h with PROT_BTI from linux v5.8
aarch64/bits/hwcap.h: add HWCAP2_MTE from linux v5.10
aarch64/bits/mman.h: add PROT_MTE from linux v5.10

Subject: [PATCH 01/11] bits/syscall.h: add process_madvise from linux v5.10
mainly added to linux to allow a central process management service in
android to give MADV_COLD|PAGEOUT hints for other processes, see
linux commit ecb8ac8b1f146915aa6b96449b66dd48984caacc
mm/madvise: introduce process_madvise() syscall: an external memory hinting API
