Subject: [PATCH 2/2] m68k: generate uapi header and syscall table header files
Unified system call table generation script must be run to
generate unistd_32.h and syscall_table.h files. This patch
will have changes which will invokes the script.
This patch will generate unistd_32.h and syscall_table.h
files by the syscall table generation script invoked by
m68k/Makefile and the generated files against the removed
files must be identical.
The generated uapi header file will be included in uapi/-
asm/unistd.h and generated system call table header file
will be included by kernel/syscalltable.S file.
Signed-off-by: Firoz Khan <firoz.khan@...aro.org>
