drm: kill dma queue support

2012-07-20T02:50:55+00:00

Absolutely unused. All the values are only ever initialized and
then used at most in some debug printout functions.

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.

drm: Compare only lower 32 bits of framebuffer map offsets

2011-06-14T01:09:54+00:00

Drivers using multiple framebuffers got broken by commit
41c2e75e60200a860a74b7c84a6375c105e7437f which ignored the framebuffer
(or register) map offset when looking for existing maps. The rationale
was that the kernel-userspace ABI is fixed at a 32-bit offset, so the
real offsets could not always be handed over for comparison.

Instead of ignoring the offset we will compare the lower 32 bit. Drivers
using multiple framebuffers should just make sure that the lower 32 bit
are different. The existing drivers in question are practically limited
to 32-bit systems so that should be fine for them.

It is assumed that current drivers always specify a correct framebuffer
map offset, even if this offset was ignored since above commit. So this
patch should not change anything for drivers using only one framebuffer.

Drivers needing multiple framebuffers with 64-bit map offsets will need
to cook up something, for instance keeping an ID in the lower bit which
is to be aligned away when it comes to using the offset.

All of above applies to _DRM_REGISTERS as well.

DRM: Replace kmalloc/memset combos with kzalloc

2010-08-11T23:12:30+00:00

Currently most, if not all, memory allocation in drm_bufs.c is followed by initializing the memory with 0.

Replace the use of kmalloc+memset with kzalloc.
