Applied to for-next/seccomp, thanks!

I made a small tweak to the last patch to add more details to the per-ARCH
help text, and to drop the needless "depends on SECCOMP" (which "depends
on SECCOMP_FILTER" was already present).

I successfully build-tested on parisc, powerpc, riscv, s390, and
sh. xtensa doesn't build using the existing Debian cross-compiler, and
I can't make csky with clang work, but they look correct. *cross fingers*
