CHERRY-PICK: exynos5: asv: Call the core ASV code early
Change the priority of ASV code initialization. The core ASV code
finds the speed group, lot id and exposes it to various consumer
drivers like busfreq, G3D and CPUfreq. Among these, the G3D driver
is getting called before the core code and thus is always getting
the ASV speed group as 0. Fix this by calling the core ASV early.

CHROMIUM: atkbd: Fix scancode handling on reconnect / resume from suspend.
On resume from suspend there is a possibility for multi-byte scancodes
to be handled incorrectly. atkbd_reconnect disables the processing of
scancodes in software by calling atkbd_disable, but the keyboard may
still be active because no disconnect command was sent. Later, software
handling is re-enabled. If a multi-byte scancode sent from the keyboard
straddles the re-enable, only the latter byte(s) will be handled.
In practice, this leads to cases where multi-byte break codes (ex. "e0
4d" - break code for right-arrow) are misread as make codes ("4d" - make
code for numeric 6), leading to one or more unwanted, untyped characters
being interpreted.
The solution implemented here involves sending command f5 (reset
disable) to the keyboard prior to disabling software handling of codes.
Later, the command to re-enable the keyboard is sent only after we are
prepared to handle scancodes.
TEST=spam right/left arrow keys during resume for many iterations,

Need BACKPORT, rather than UPSTREAM, since it won't apply cleanly because
we had already fixed the MODULE_LICENSE problem.
---original comment:
ZSMALLOC is tristate, but the code has no MODULE_LICENSE and since it
depends on GPL-only symbols it cannot be loaded as a module. This in
turn breaks zram which now depends on it. I assume it's meant to be
Dual BSD/GPL like the other z-stuff.
There is also no module_exit, which will make it impossible to unload.

CHROMIUM: sound / hda: Fix D0 power state checking.
Power state checking for HDA cards is broken. According to the HDA spec, the
lower four bits of the power state register define the "set" power state and
the next four bits define the "actual" state. Subsequent bits have different
meanings. When we check the power state of our card during transition to D0,
we read the entire register and compare to AC_PWRST_D0 (0). This leads to
timeout of the wait loop and ~500ms wasted during resume if some upper
status bits are set.
Solution is to mask off all upper bits and compare only get + set state. If
these states are 0, it means the transition has completed.
This is fixed differently in the mainstream kernel repo, but there are some
extra dependencies involved. Therefore, this patch should NOT be carried
forward through the next kernel rebase.
DO NOT CARRY FORWARD.
TEST=Run power_Resume test on HDA card that reports PS-ClkStopOk status.
