ba4a28bb16 drm/gma500: Add support for the nomodeset kernel parameter 
According to disable Documentation/admin-guide/kernel-parameters.txt, this
parameter can be used to disable kernel modesetting.

DRM drivers will not perform display-mode changes or accelerated rendering
and only the system framebuffer will be available if it was set-up.

But only a few DRM drivers currently check for nomodeset, make this driver
to also support the command line parameter.

8b250cd3b5 drm/gma: Remove calls to kmap() 
kmap() is being deprecated and these instances are easy to convert to
kmap_local_page().

Furthermore, in gma_crtc_cursor_set() use the memcpy_from_page() helper

e1f80341e3 drm/gma500: Rewrite GTT page insert/remove without struct gtt_range 
struct gtt_range represents a GEM object and should not be used for GTT
setup. Change psb_gtt_insert() and psb_gtt_remove() to receive all
necessary parameters from their caller. This also eliminates possible
failure from psb_gtt_insert().

There's one exception in psb_gtt_restore(), which requires an upcast
from struct resource to struct gtt_range when restoring the GTT after
hibernation. A possible solution would track the GEM objects that need
restoration separately from the GTT resource.

Rename the functions to psb_gtt_insert_pages() and psb_gtt_remove_pages()
to reflect their similarity to MMU interfaces.

3c101135ba drm/gma500: Inline psb_gtt_{alloc,free}_range() into rsp callers 
psb_gtt_alloc_range() allocates struct gtt_range, create the GTT resource
and performs some half-baked initialization. Inline the function into its
only caller psb_gem_create(). For creating the GTT resource, introduce a
new helper, psb_gtt_alloc_resource() that hides the details of the GTT.

For psb_gtt_free_range(), inline the function into its only caller
psb_gem_free_object(). While at it, remove the explicit invocation of
drm_gem_free_mmap_offset(). The mmap offset is already released by

957a2d0e7e drm/gma500: Allocate GTT ranges in stolen memory with psb_gem_create() 
Support private objects for stolen memory in psb_gem_create() and
convert users to psb_gem_create(). For stolen memory, psb_gem_create()
now initializes the GEM object via drm_gem_private_object_init().

In the fbdev setup, replace the open-coded initialization of struct
gtt_range with a call to psb_gem_create(). Use drm_gem_object_put()
for release.

In the cursor setup, use psb_gem_create() and get a real GEM object.
Previously the allocated instance of struct gtt_range was only partially
initialized. Release the cursor GEM object in gma_crtc_destroy(). The
release was missing from the original code.

With the conversion of all callers to psb_gem_create(), the extern
declarations of psb_gtt_alloc_range, psb_gtt_free_range and
psb_gem_object_func are not required any longer. Declare them as
static.

ac798eb13c drm/gma500: Remove CONFIG_X86 conditionals from source files 
Remove the CONFIG_X86 conditionals from the source code. The driver
already depends on X86 in the Kconfig file. Also, no one has been
trying to build it on a non-x86 platform recently, or they would have
noticed that drm_ttm_cache_flush() doesn't exist.

26499e0518 drm/gma500: Drop DRM_GMA3600 config option 
With support for the MID-related chips removed, only support for
desktop chips is left in the driver. So just build the complete
driver if DRM_GMA500 has been selected. Anyone who wants to enable
the Poulsbo code would probably also want the Cedarview code.

6f02e9df2a drm/gma500: Remove in_atomic() usage. 
The driver is using msleep() if it is safe to use based on in_atomic().
This is not needed this macro is only used from
i2c_algorithm::master_xfer() which is always invoked from preemptible
context.

Remove in_atomic() because it is superfluous. Remove wait_for_atomic()
because it has no users.
