Merge branch 'linus' into perf/urgent

Merge back Linus's latest branch so that we pick up the uprobes changes.

( I tested this branch locally and while it's one from the middle of the
  merge window it's a good one to base further work off. )

-/*
- *
- *	Trampoline.S	Derived from Setup.S by Linus Torvalds
- *
- *	4 Jan 1997 Michael Chastain: changed to gnu as.
- *
- *	This is only used for booting secondary CPUs in SMP machine
- *
- *	Entry: CS:IP point to the start of our code, we are 
- *	in real mode with no stack, but the rest of the 
- *	trampoline page to make our stack and everything else
- *	is a mystery.
- *
- *	We jump into arch/x86/kernel/head_32.S.
- *
- *	On entry to trampoline_data, the processor is in real mode
- *	with 16-bit addressing and 16-bit data.  CS has some value
- *	and IP is zero.  Thus, data addresses need to be absolute
- *	(no relocation) and are taken with regard to r_base.
- *
- *	If you work on this file, check the object module with
- *	objdump --reloc to make sure there are no relocation
- *	entries except for:
- *
- *	TYPE              VALUE
- *	R_386_32          startup_32_smp
- *	R_386_32          boot_gdt
