drm/exynos: fix vsync interrupt clear rountine of mixer
INT_EN_VSYNC bit is not used when we clear vsync interrupt but
INT_STATUS_VSYNC bit should be related.
Also, if we want to enable vsync interrupt, we should write 1 in
INT_CLEAR_VSYNC bit before we set INT_EN_VSYNC bit. It will clear prior
vsync interrupt. You can check it from exynos mixer user manual.

Repeately turning on and off a layer, sometimes page fault occurs. This
problem seems to happen, because of H/W malfunction during turning on
the layer. But it can be solved by setting the framebuffer source size
by 0.

one and fixes the minor issue present with the old code (support
for 'boost' mode in the exynos-cpufreq driver was enabled for all

cpufreq-dt: add 'boost' mode frequencies support
Add 'boost' mode frequencies support:
- add boost-opps binding to cpufreq-dt driver bindings
- make cpufreq_init() adjust freq_table accordingly
- fix set_target() to handle boost frequencies
- add boost_supported field to struct cpufreq_dt_platform_data
- set dt_cpufreq_driver.boost_supported in dt_cpufreq_probe()
This patch makes cpufreq-dt driver aware of 'boost' mode frequencies
and prepares it for adding support for Exynos4x12 'boost' support.
boost-opps binding is currently limited to cpufreq-dt but once there is
a need for cpufreq wide and/or generic Linux device support for 'boost'
mode cpufreq-dt can be updated to handle the new code without changing
the binding itself.
The decision to make 'boost' mode support limited to cpufreq-dt driver
for now was taken because 'boost' mode is currently a niche feature and
code needed for parsing boost-opps binding is minimal and simple. More
generic (i.e. separate 'boost' OPPs list in struct device and generic
cpufreq convertion of them to freq_table format) support would need far
more code and effort to make it work. Doing it without a demonstrated
real need would be on overengineering IMHO.

result in dereferencing the NULL pointer on error

clk: add CLK_RECALC_NEW_RATES clock flag for Exynos cpu clock support
This flag is needed to fix the issue with wrong dividers being setup
by Common Clock Framework when using the new Exynos cpu clock support.
The issue happens because clk_core_set_rate_nolock() calls
clk_calc_new_rates(clk, rate) before both pre/post clock notifiers have
a chance to run. In case of Exynos cpu clock support pre/post clock
notifiers are registered for mout_apll clock which is a parent of armclk
cpu clock and dividers are modified in both pre and post clock notifier.
This results in wrong dividers values being later programmed by
clk_change_rate(top). To workaround the problem CLK_RECALC_NEW_RATES
flag is added and it is set for mout_apll clock later so the correct
divider values are re-calculated after both pre and post clock notifiers
had run.

arm64: add KASAN support
This patch adds arch specific code for kernel address sanitizer
(see Documentation/kasan.txt).
1/8 of kernel addresses reserved for shadow memory. There was no
big enough hole for this, so virtual addresses for shadow were
stolen from vmalloc area.
At early boot stage the whole shadow region populated with just
one physical page (kasan_zero_page). Later, this page reused
as readonly zero shadow for some memory that KASan currently
don't track (vmalloc).
After mapping the physical memory, pages for shadow memory are
allocated and mapped.
Functions like memset/memmove/memcpy do a lot of memory accesses.
If bad pointer passed to one of these function it is important
to catch this. Compiler's instrumentation cannot do this since
these functions are written in assembly.
KASan replaces memory functions with manually instrumented variants.
Original functions declared as weak symbols so strong definitions
in mm/kasan/kasan.c could replace them. Original functions have aliases
with '__' prefix in name, so we could call non-instrumented variant
if needed.
Some files built without kasan instrumentation (e.g. mm/slub.c).
Original mem* function replaced (via #define) with prefixed variants
to disable memory access checks for such files.

drm: bridge: Allow daisy chaining of bridges
Allow drm_bridge objects to link to each other in order to form an encoder
chain. The requirement for creating a chain of bridges comes because the
MSM drm driver uses up its encoder and bridge objects for blocks within
the SoC itself. There isn't anything left to use if the SoC display output
is connected to an external encoder IC. Having an additional bridge
connected to the existing bridge helps here. In general, it is possible for
platforms to have multiple devices between the encoder and the
connector/panel that require some sort of configuration.
We create drm bridge helper functions corresponding to each op in
'drm_bridge_funcs'. These helpers call the corresponding
'drm_bridge_funcs' op for the entire chain of bridges. These helpers are
used internally by drm_atomic_helper.c and drm_crtc_helper.c.
The drm_bridge_enable/pre_enable helpers execute enable/pre_enable ops of
the bridge closet to the encoder, and proceed until the last bridge in the
chain is enabled. The same holds for drm_bridge_mode_set/mode_fixup
helpers. The drm_bridge_disable/post_disable helpers disable the last
bridge in the chain first, and proceed until the first bridge in the chain
is disabled.
drm_bridge_attach() remains the same. As before, the driver calling this
function should make sure it has set the links correctly. The order in
which the bridges are connected to each other determines the order in which
the calls are made. One requirement is that every bridge in the chain
should point the parent encoder object. This is required since bridge
drivers expect a valid encoder pointer in drm_bridge. For example, consider
a chain where an encoder's output is connected to bridge1, and bridge1's
output is connected to bridge2:
/* Like before, attach bridge to an encoder */
bridge1->encoder = encoder;
ret = drm_bridge_attach(dev, bridge1);
..
/*
* set the first bridge's 'next' bridge to bridge2, set its encoder
* as bridge1's encoder
*/
bridge1->next = bridge2
bridge2->encoder = bridge1->encoder;
ret = drm_bridge_attach(dev, bridge2);
...
...
This method of bridge chaining isn't intrusive and existing drivers that
use drm_bridge will behave the same way as before. The bridge helpers also
cleans up the atomic and crtc helper files a bit.
