Intel processors are adding enhancements to REP MOVSB/STOSB and the use of REP MOVSB/STOSB for optimal memcpy/memset or similar functions is recommended. Enhancement availability is indicated by CPUID.7.0.EBX[9] (Enhanced REP MOVSB/ STOSB). Support clear_page() with rep stosb for processor supporting enhanced REP MOVSB /STOSB.

Some string operation functions may be patched twice, e.g. on enhanced REP MOVSB /STOSB processors, memcpy is patched first by fast string alternative function, then it is patched by enhanced REP MOVSB/STOSB alternative function.

Commit a626ca6a ("vm: fix vm_pgoff wrap in stack expansion") fixed the case of an expanding mapping causing vm_pgoff wrapping when you had downward stack expansion. But there was another case where IA64 and PA-RISC expand mappings: upward expansion. This fixes that case too.

Linux kernel excludes guard page when performing mlock on a VMA with down-growing stack. However, some architectures have up-growing stack and locking the guard page should be excluded in this case too. This patch fixes lvm2 on PA-RISC (and possibly other architectures with up-growing stack). lvm2 calculates number of used pages when locking and when unlocking and reports an internal error if the numbers mismatch. [ Patch changed fairly extensively to also fix /proc/<pid>/maps for the grows-up case, and to move things around a bit to clean it all up and share the infrstructure with the /proc bits. Tested on ia64 that has both grow-up and grow-down segments - Linus ] Signed-off-by: NMikulas Patocka <mikulas@artax.karlin.mff.cuni.cz> Tested-by: NTony Luck <tony.luck@gmail.com> Cc: stable@kernel.org Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

If we're using vga switcheroo, the device may be turned off and poking it can return random state. This provokes an OOPS fixed separately by 8ff887c847 (drm/i915/dp: Be paranoid in case we disable a DP before it is attached). Trying to use and respond to events on a device that has been turned off by the user is in principle a silly thing to do.

Despite the fixes in 548f245b (drm/i915: fix per-pipe reads after "cleanup"), we missed one neighbouring read that was mistakenly replaced with the reg value in 9db4a9c7 (drm/i915: cleanup per-pipe reg usage). This was preventing us from correctly determining the mode the BIOS left the panel in for machines that neither have an OpRegion nor access to the VBT, (e.g. the EeePC 700).
