Applied, thanks. Sorry it took so long...I was kind of wondering what
happened to the rest of the series and then I forgot about the whole
thing.

Basically I prepared syscalls.h for x86 :

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=arch/x86/include/asm/syscalls.h;h=87803da440100d50222d86cf7a1ac9cf00ed29ca;hb=HEAD

On David's request I also prepared for other arch.

But it totally depends on arch maintainers to include or not.

Thank you,

Jaswinder Singh.
