[PATCH v3 3/3] sh: generate uapi header and syscall table header files
From: Firoz Khan
Date: Tue Nov 13 2018 - 23:32:57 EST
System call table generation script must be run to gener-
ate 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
sh/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/syscall_32.S file.
