2021-08-10scripts: make some scripts executableMasahiro Yamada1-0/+0
Set the x bit to some scripts to make them directly executable. Especially, scripts/checkdeclares.pl is not hooked by anyone. It should be executable since it is tedious to type 'perl scripts/checkdeclares.pl'. The original patch [1] set the x bit properly, but it was lost when it was merged as commit 21917bded72c ("scripts: a new script for checking duplicate struct declaration").

2021-07-08scripts: add generic syscallnr.shMasahiro Yamada1-0/+74
Like syscallhdr.sh and syscalltbl.sh, add a simple script to generate the __NR_syscalls, which should not be exported to userspace. This script is useful to replace arch/mips/kernel/syscalls/syscallnr.sh, refactor arch/s390/kernel/syscalls/syscalltbl, and eliminate the code surrounded by #ifdef __KERNEL__ / #endif from exported uapi/asm/unistd_*.h files.
