vm: fix vm_pgoff wrap in upward expansion

2011-05-10T00:52:17Z

Commit a626ca6a6564 ("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. Signed-off-by: Hugh Dickins Cc: stable@kernel.org Signed-off-by: Linus Torvalds

Don't lock guardpage if the stack is growing up

2011-05-09T23:22:07Z

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//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: Mikulas Patocka Tested-by: Tony Luck Cc: stable@kernel.org Signed-off-by: Linus Torvalds

drm/i915/lvds: Only act on lid notify when the device is on

2011-05-09T16:13:22Z

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.

drm/i915: fix intel_crtc_clock_get pipe reads after "cleanup cleanup"

2011-05-09T16:13:21Z

Despite the fixes in 548f245ba6a31 (drm/i915: fix per-pipe reads after "cleanup"), we missed one neighbouring read that was mistakenly replaced with the reg value in 9db4a9c (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).

drm/i915: Only enable the plane after setting the fb base (pre-ILK)

2011-05-09T16:13:20Z

When enabling the plane, it is helpful to have already pointed that plane to valid memory or else we may incur the wrath of a PGTBL_ER. This code preserved the behaviour from the bad old days for unknown reasons... Found by assert_fb_bound_for_plane().
