Reverse boosting is also seen on the DC charging path
and may cause charger removal detection problems.
Fix this by changing the reverse boost detection to only
check the active charging path. Only the active charging
path will see reverse boosting voltages because the other
path's OVP will automatically be opened (off) by the
hardware.

For every soc calculations there are three unusable charge (uuc)
values.
uuc_uah_itest:
The uuc value in micro amp hour (uah) based on the max current
(itest). Typically this value is very high and changes as the
battery resistance changes
uuc_uah_iavg:
The uuc value based on the average current (iavg). Typically
this is lower than uuc_itest
uuc_reported:
The reported uuc based on state of charge (SOC) of the battery
which chooses a stepsize value and approaches towards
uuc_uah_itest or uuc_uah_iavg based on whether the device is
being charged.
The expectation is that the reported uuc increase as the battery looses SOC
and decrease as SOC approaches full condition.
To help us coming up with a satisfactory algorithm the following
parameters are introduced.
uuc_multiplier:
The multiplier used in stepsize calculation
uuc_iavg_div:
The divisor to use in calculation of stepsize when there
is a significant jump in average current from the
previous attempt
uuc_min_step_size:
The minimum stepsize to use if the calculated stepsize is very less
Also, in order to ignore the high bootup time load a timer is introduced
which makes the algorithm ignore iavg values upon bootup.
The algorithm also uses the previous uuc based on iavg in
"uuc_uah_iavg_prev". This aids in checking if there was a significant
increase in average current from the previous time uuc was calculated.
The algorithm keeps track of the previous reported uuc in last_uuc_uah.

During a subsystem restart or a line-discipline unload with active data
transfer, the logical channel purge function (smux_lch_purge) could lead
to a deadlock while flushing the workqueues if it is called with
mutex_lha0 locked and one of the worker functions calls a function that
locks mutex_lha0. In addition, the local mode was reset which is not
expected behavior.
This change aborts all work functions in the case of a reset allowing
the flush to be performed without any locks held. Once the flush is
complete, then the appropriate locks can be obtained before the reset
flag is cleared and work items can once again get scheduled.

User memory needs to be zeroed out before it is sent to the user.
To do this, the kernel maps the page, memsets it to zero and then
unmaps it. By virtue of mapping it, this forces us to flush the
dcache to ensure cache coherency between kernel and user mappings.
Originally, the page_alloc loop was using GFP_ZERO (which does a
map, memset, and unmap for each individual page) and then we were
additionally calling flush_dcache_page() for each page killing us
on performance. It is far more efficient, especially for large
allocations (> 1MB), to allocate the pages without GFP_ZERO and
then to vmap the entire allocation, memset it to zero, flush the
cache and then unmap. This process is slightly slower for very
small allocations, but only by a few microseconds, and is well
within the margin of acceptability. In all, the new scheme is
faster than the default for all sizes greater than 16k, and is
almost 4X faster for 2MB and 4MB allocations which are common for
textures and very large buffer objects.
The downside is that if there isn't enough vmalloc room for the
allocation that we are forced to fallback to a slow page by
page memset/flush, but this should happen rarely (if at all) and
is only included for completeness.
