sys/arch/amd64/amd64: locore.S spl.S vector.S
Log message:
Split "return to userspace via iretq" from intr_fast_exit into intr_user_exit.
Move AST handling from the bottom of alltraps and Xdoreti to the
top of the new routine.
syscall-return-via-iretq and the FPU #DNA trap jump into intr_user_exit after
the AST check (already performed for the former, skipped for the latter)
Delete a couple debugging hooks mlarkin@ and I used during Meltdown work
tested by many in snaps; thanks to brynet@ for spurious interrrupt testing
earlier reviews and comments kettenis@ mlarkin@; prodding from deraadt@
