Commit Message

Firoz Khan Jan. 7, 2019, 2:52 p.m. UTC 
Add Makefile to invoke the system call table generation script
which is placed in scripts directory as a common location acc-
essible for all the architectures.

scripts/syscallhdr.sh will generate uapi header and scripts-
/syscalltbl.sh will generate kapi header respectively. There
is another scripts scripts/syscallnr.sh can generate total
number of syscall which doesn't invoke from this Makefile.
