Most of architectures generate syscall headers at the compile time
in a similar way.
As of v5.11-rc1, 12 architectures duplicate similar shell scripts:
$ find arch -name syscallhdr.sh | sort
arch/alpha/kernel/syscalls/syscallhdr.sh
arch/arm/tools/syscallhdr.sh
arch/ia64/kernel/syscalls/syscallhdr.sh
arch/m68k/kernel/syscalls/syscallhdr.sh
arch/microblaze/kernel/syscalls/syscallhdr.sh
arch/mips/kernel/syscalls/syscallhdr.sh
arch/parisc/kernel/syscalls/syscallhdr.sh
arch/powerpc/kernel/syscalls/syscallhdr.sh
arch/sh/kernel/syscalls/syscallhdr.sh
arch/sparc/kernel/syscalls/syscallhdr.sh
arch/x86/entry/syscalls/syscallhdr.sh
arch/xtensa/kernel/syscalls/syscallhdr.sh
My goal is to unify them into scripts/syscallhdr.sh.
