These are dead code since 3.7. If there is no plan to use them further,

The ast driver inherits from DRM's CRTC state, but still uses the atomic
helper for struct drm_crtc_funcs.reset, drm_atomic_helper_crtc_reset().
The helper only allocates enough memory for the core CRTC state. That
results in an out-ouf-bounds access when duplicating the initial CRTC
state. Simplified backtrace shown below:

The Tegra DRM drivers includes the legacy GPIO headers
<linux/gpio.h> and <linux/of_gpio.h> but what it really
uses is <linux/gpio/consumer.h> since only gpio_desc
structs are ever referenced.
Include the right header on the top level tegra/drm.h
file and drop all the surplus includes.

The driver forgets to free the I/O region in remove and probe
failure.
Add the missed calls to fix it.
Since the success of request_region() is optional, add the "region" field
in vesafb_par to represent whether request_region() succeeds.
Then only call release_region() when "region" is not null.

The fbdev framework doesn't care to call the .set_power callback only on
changes. So the driver has to care for itself that the regulator doesn't
get disabled more often than enabled.
This fixes the regulator warning
unbalanced disables for lcd supply
which can be triggered by doing
echo 4 > /sys/class/lcd/imxfb-lcd/lcd_power
twice.

Daniel noted[1] that commit d606dc9a6323 ("drm: kirin: Add

and incorrect, as drm_dev_register does register connectors for
us.
Thus, this patch reverts the change as suggested by Daniel.

Pull more Kbuild updates from Masahiro Yamada:
- raise minimum supported binutils version to 2.23
- remove old CONFIG_AS_* macros that we know binutils >= 2.23 supports
- move remaining CONFIG_AS_* tests to Kconfig from Makefile
- enable -Wtautological-compare warnings to catch more issues
- do not support GCC plugins for GCC <= 4.7
- fix various breakages of 'make xconfig'
- include the linker version used for linking the kernel into
LINUX_COMPILER, which is used for the banner, and also exposed to
/proc/version
- link lib-y objects to vmlinux forcibly when CONFIG_MODULES=y, which
allows us to remove the lib-ksyms.o workaround, and to solve the last
known issue of the LLVM linker
- add dummy tools in scripts/dummy-tools/ to enable all compiler tests
in Kconfig, which will be useful for distro maintainers
- support the single switch, LLVM=1 to use Clang and all LLVM utilities
instead of GCC and Binutils.

There are many places where all basic VMA access flags (read, write,
exec) are initialized or checked against as a group. One such example
is during page fault. Existing vma_is_accessible() wrapper already
creates the notion of VMA accessibility as a group access permissions.
Hence lets just create VM_ACCESS_FLAGS (VM_READ|VM_WRITE|VM_EXEC) which
will not only reduce code duplication but also extend the VMA
accessibility concept in general.
