Merge branch 'linus' into tracing/hw-breakpoints
Conflicts:
arch/x86/Kconfig
arch/x86/kernel/traps.c
arch/x86/power/cpu.c
arch/x86/power/cpu_32.c
kernel/Makefile
Semantic conflict:
arch/x86/kernel/hw_breakpoint.c
Merge reason: Resolve the conflicts, move from put_cpu_no_sched() to
put_cpu() in arch/x86/kernel/hw_breakpoint.c.
