Subject: [PATCH 00/27] arch: syscalls: unifiy all syscalltbl.sh into scripts/syscalltbl.sh
As of v5.11-rc1, 12 architectures duplicate similar shell scripts:
$ find arch -name syscalltbl.sh | sort
arch/alpha/kernel/syscalls/syscalltbl.sh
arch/arm/tools/syscalltbl.sh
arch/ia64/kernel/syscalls/syscalltbl.sh
arch/m68k/kernel/syscalls/syscalltbl.sh
arch/microblaze/kernel/syscalls/syscalltbl.sh
arch/mips/kernel/syscalls/syscalltbl.sh
arch/parisc/kernel/syscalls/syscalltbl.sh
arch/powerpc/kernel/syscalls/syscalltbl.sh
arch/sh/kernel/syscalls/syscalltbl.sh
arch/sparc/kernel/syscalls/syscalltbl.sh
arch/x86/entry/syscalls/syscalltbl.sh
arch/xtensa/kernel/syscalls/syscalltbl.sh
This patch set unifies all of them into a single file,
scripts/syscalltbl.sh.
The code-diff is attractive:

delete mode 100644 arch/xtensa/kernel/syscalls/syscalltbl.sh
create mode 100644 scripts/syscalltbl.sh
Also, this includes Makefile fixes, and some x86 fixes and cleanups.
My question is, how to merge this series.
I am touching all architectures, but the first patch is a prerequisite
of the rest of this series.
One possibility is to ask the x86 maintainers to pickup the first 5
patches for v5.12-rc1, and then send the rest for v5.13-rc1,
splitting per-arch.
I want the x86 maintainers to check the first 5 patches because
I cleaned up the x32 code.
I know x32 was considered for deprecation, but my motivation is to
clean-up scripts across the tree without changing the functionality.
