* [PATCH] seccomp: switch to using asm-generic for seccomp.h

Most architectures don't need to do anything special for the strict
seccomp syscall entries. Remove the redundant headers and reduce the
others.

I think that these cases (where you replace the file by a stub that
just include <asm-generic/seccomp.h>) can be replaced by removing the
file completely and adding
generic-y = seccomp.h
to <ARCH>/include/asm/Kbuild

I think that these cases (where you replace the file by a stub that
just include <asm-generic/seccomp.h>) can be replaced by removing the
file completely and adding
generic-y = seccomp.h
to <ARCH>/include/asm/Kbuild

Ah-ha! I thought total removal was possible, but I lacked the Kbuild
piece. There are a lot of arch/ headers that are just the one line.
Maybe I should send a another patch to clean up those?
