Patch 1 is IMO a bug fix.
Patch 2 is a cleanup and avoids some confusion. It's also sort of an
API break (no ABI change) because it removes a struct field. But that
struct field has never done anything at all as far as I can tell.
AFAICT this series got bogged down in discussion about patch 2 last
time. I'm only including patch 2 for completeness here -- patch 1
is IMO far more useful, and I'm fine with patch 1 being merged and
tabling patch 2 again.
Changes from v1:
- Add the __USER_DS fix, caught by my sigreturn test.
- Re-tested locally.

x86_64,signal: Fix SS handling for signals delivered to 64-bit
programs
x86_64,signal: Remove 'fs' and 'gs' from sigcontext
