Merge branch 'linus' into perf/kprobes
Conflicts:
include/asm-generic/atomic-instrumented.h
kernel/kprobes.c
Use the upstream atomic-instrumented.h checksum, and pick
the kprobes version of kernel/kprobes.c, which effectively
reverts this upstream workaround:
645f224e7ba2: ("kprobes: Tell lockdep about kprobe nesting")
Since the new code *should* be fine without nesting.
Knock on wood ...
