Hi Linus,

please pull the x86/core pile for 5.17.

This one got delayed a bit due to a testcase failure. But that has been
taken care of now and the last (newest) patch is the fix.

Thx.

x86/entry_32: Fix segment exceptions (2022-01-12 16:38:25 +0100)

----------------------------------------------------------------
- Get rid of all the .fixup sections because this generates
misleading/wrong stacktraces and confuse RELIABLE_STACKTRACE and
LIVEPATCH as the backtrace misses the function which is being fixed up.

- Add Straight Light Speculation mitigation support which uses a new
compiler switch -mharden-sls= which sticks an INT3 after a RET or an
indirect branch in order to block speculation after them. Reportedly,
CPUs do speculate behind such insns.

- The usual set of cleanups and improvements
