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
