System call table generation script must be run to gener- ate unistd_32/64.h and syscall_table_32/64/c32.h files. This patch will have changes which will invokes the script.
This patch will generate unistd_32/64.h and syscall_table- _32/64/c32.h files by the syscall table generation script invoked by parisc/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.S file.
