From 0d284a3933c612c40e29aaa9cced4ab17b59e74f Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 4 Apr 2016 12:38:46 -0700 Subject: gma500: remove annoying deprecation warning commit 166c5a6ef765653848161e6f4af81c05e4b3ecf6 upstream. In commit e45708976aea ("drm/dp-helper: Move the legacy helpers to gma500") the legacy i2c helpers were moved to the only remaining user of them, the gma500 driver. Together with that move, i2c_dp_aux_add_bus() was marked deprecated and started warning about its remaining use. It's now been a year and a half of annoying warning, and apparently nobody cares enough about gma500 to try to move it along to the more modern models. Get rid of the warning - if even the gma500 people don't care enough, then they should certainly not spam other innocent developers with a warning that might hide other, much more real issues.

VMA offsets are 64 bits. Plane surface offsets are in ggtt and the hardware register to set this is thus 32 bits. Be explicit about these and convert carefully to from vma to final size. This will make sparse happy by not creating 32bit pointers out of 64bit vma offsets.

Kristensen" Date: Tue, 13 Sep 2016 14:20:45 -0700 Subject: drm: Only use compat ioctl for addfb2 on X86/IA64 commit 47a66e45d7a7613322549c2475ea9d809baaf514 upstream. Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an unaligned 64 bit field (modifier). This get packed differently between 32 bit and 64 bit modes on architectures that can handle unaligned 64 bit access (X86 and IA64). Other architectures pack the structs the same and don't need the compat wrapper. Use the same condition for drm_mode_fb_cmd2 as we use for drm_update_draw. Note that only the modifier will be packed differently between compat and non-compat versions. Reviewed-by: Rob Clark Signed-off-by: Kristian H.
