[PATCH] update-linux-headers: Remove "asm-s390/unistd_32.h"

[PATCH] update-linux-headers: Remove "asm-s390/unistd_32.h"

[Cédric Le Goater]

The "asm/unistd_32.h" file was generated for the 31-bit compatibility
mode on the s390 architecture and support was removed in v6.19-rc1,
commit 4ac286c4a8d9 ("s390/syscalls: Switch to generic system call
table generation")

unistd_32.h is no longer generated when running make header_install.
Remove it.

I think it would make sense to remove linux-headers/asm-s390/unistd_32.h in 
this patch, too, otherwise this will stay around as a stale file, I guess?

Anyway,

AFAICT, it will be removed at the first update of linux-headers. See :

Yes, the script purges the old files before installing the new versions.
