I have written a shell script to generate the syscall_nr.h from the
asm-generic, but as it uses a lot of cpp, tr, sed and grep, the result
needs to be checked.

If it can help, it is in attachment.

Put it in scripts, and run it as:

scripts/gensyscalls.sh /path/to/linux

then check the result with something like "git diff -w"
