[PATCH 00/15] selftests/seccomp: Refactor change_syscall()

Hi,

This refactors the seccomp selftest macros used in change_syscall(),
in an effort to remove special cases for mips, arm, arm64, and xtensa,
which paves the way for powerpc fixes.

I'm not entirely done testing, but all-arch build tests and x86_64
selftests pass. I'll be doing arm, arm64, and i386 selftests shortly,
but I currently don't have an easy way to check xtensa, mips, nor
powerpc. Any help there would be appreciated!

(FWIW, I expect to take these via the seccomp tree.)

Thanks,

-Kees
