VM: add "vm_mmap()" helper function

2012-04-21T00:29:13+00:00

This continues the theme started with vm_brk() and vm_munmap():
vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.

This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c.  But that way we don't have
to export our internal do_mmap_pgoff() function.

Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead.  We're actually
very close to that already, with the notable exception of the (broken)
use in i810, and a couple of stragglers in binfmt_elf.

VM: add "vm_munmap()" helper function

2012-04-21T00:29:13+00:00

Like the vm_brk() function, this is the same as "do_munmap()", except it
does the VM locking for the caller.

nouveau: Set special lane map for the right chipset

2012-04-19T15:37:53+00:00

The refactoring of the nv50 logic, introduced in 8663bc7c, modified the
test for the special lane map used on some Apple computers with Nvidia
chipsets. The tested MBA3,1 would still boot, but resume from suspend
stopped working. This patch restores the old test, which fixes the problem.

drm/radeon: fix load detect on rn50 with hardcoded EDIDs.

2012-04-19T15:02:18+00:00

When the force changes went in back in 3.3.0, we ended up returning
disconnected in the !force case, and the connected in when forced,
as it hit the hardcoded check.

Fix it so all exits go via the hardcoded check and stop spurious
modesets on platforms with hardcoded EDIDs.

drm: Releasing FBs before releasing GEM objects during drm_release

2012-04-19T13:40:41+00:00

During DRM release, all the FBs and gem objects are released. If
a gem object is being used as a FB and set to a crtc, it must not
be freed before releasing the framebuffer first.

If FBs are released first, the crtc using the FB is disabled first
so now the GEM object can be freed safely. The CRTC will be enabled
again when the driver restores fbdev mode.

drm/nouveau/pm: don't read/write beyond end of stack buffer

2012-04-19T13:38:54+00:00

NUL-terminate after strncpy.

If the parameter "profile" has length 16 or more, then strncpy
leaves "string" with no NUL terminator, so the following search
for '\n' may read beyond the end of that 16-byte buffer.
If it finds a newline there, then it will also write beyond the
end of that stack buffer.

drivers: gpu: drm: gma500: mdfld_dsi_output.h: Remove not unneeded include of version.h

2012-04-19T13:38:02+00:00

The output of "make versioncheck" points a incorrect include of
version.h in the drivers/gpu/drm/gma500/mdfld_dsi_output.h:

drivers/gpu/drm/gma500/mdfld_dsi_output.h: 32 linux/version.h not needed.

If we take a look in the file, we can agree to remove it.

radeon: fix r600/agp when vram is after AGP (v3)

2012-04-19T13:37:42+00:00

If AGP is placed in the middle, the size_af is off-by-one, it results
in VRAM being placed at 0x7fffffff instead of 0x8000000.

v2: fix the vram_start setup.
v3: also fix r7xx & newer ASIC
