We observed that SoC suddenly increase from 98% or 99% to 100%
right after charger removal. This issue caused by charging adjusting
algorithm which adjust SoC to sync 100% with end of charging.
During charging adjustment, the adjusted SoC could be smaller than
original SoC. So when we remove charger, charging adjusting algorithm
stop adjusting SoC and then bms report original SoC which is larger
than before.
Previously, bms driver considered most of this case by using previous
SoC when SoC increase during discharging. But if SoC is 100%, previous
patch doesn't work.
So this patch add SoC 100% case by checking if charger is enabled.

HSIC HW can operate at SVS digital voltage when it is active.
Currently HSIC is voting for 120Mhz SFAB and 64Mhz DFAB clock
frequencies. Clock frequencies are directly proportional to SVS
voltage. If DFAB is running at 64Mhz or SFAB is running at 120Mhz
or higher SVS is not possible even though HSIC votes for it. Hence
do not vote for SFAB clock frequency and only vote for 32Mhz for
DFAB in order to allow SVS to happen. Voting for SVS voltage reduces
current consumption by 3mA in HSDPA network.

HSIC generates interrupt at 4ms interval. If idle power collapse
is enabled when HSIC is active, krait keeps on going into idle
power collapse requesting RPM to handle the sleep set requirement.
If HSIC interrupt comes after 4ms interval, krait comes out of idle
power collapse and it again ask RPM to handle this request therefore
keeps RPM busy handling requests due to frequent idle power collapse.
This has a power impact. Hence only allow standalone power collapse
when HSIC is active to avoid RPM involvement in assisting kraits to
power collapse. Vote for idle power collapse when HSIC goes to low
power mode.

In ext4_nonda_switch(), if the file system is getting full we used to
call writeback_inodes_sb_if_idle(). The problem is that we can be
holding i_mutex already, and this causes a potential deadlock when
writeback_inodes_sb_if_idle() when it tries to take s_umount. (See
lockdep output below).
As it turns out we don't need need to hold s_umount; the fact that we
are in the middle of the write(2) system call will keep the superblock
pinned. Unfortunately writeback_inodes_sb() checks to make sure
s_umount is taken, and the VFS uses a different mechanism for making
sure the file system doesn't get unmounted out from under us. The
simplest way of dealing with this is to just simply grab s_umount
using a trylock, and skip kicking the writeback flusher thread in the
very unlikely case that we can't take a read lock on s_umount without
blocking.
Also, we now check the cirteria for kicking the writeback thread
before we decide to whether to fall back to non-delayed writeback, so
if there are any outstanding delayed allocation writes, we try to get
them resolved as soon as possible.

Commit 080399aaaf ("block: don't mark buffers beyond end of disk as
mapped") exposed a bug in __getblk_slow that causes mount to hang as it
loops infinitely waiting for a buffer that lies beyond the end of the
disk to become uptodate.
The problem was initially reported by Torsten Hilbrich here:
https://lkml.org/lkml/2012/6/18/54
and also reported independently here:
http://www.sysresccd.org/forums/viewtopic.php?f=13&t=4511
and then Richard W.M. Jones and Marcos Mello noted a few separate
bugzillas also associated with the same issue. This patch has been
confirmed to fix:
https://bugzilla.redhat.com/show_bug.cgi?id=835019
The main problem is here, in __getblk_slow:
for (;;) {
struct buffer_head * bh;
int ret;
bh = __find_get_block(bdev, block, size);
if (bh)
return bh;
ret = grow_buffers(bdev, block, size);
if (ret < 0)
return NULL;
if (ret == 0)
free_more_memory();
}
__find_get_block does not find the block, since it will not be marked as
mapped, and so grow_buffers is called to fill in the buffers for the
associated page. I believe the for (;;) loop is there primarily to
retry in the case of memory pressure keeping grow_buffers from
succeeding. However, we also continue to loop for other cases, like the
block lying beond the end of the disk. So, the fix I came up with is to
only loop when grow_buffers fails due to memory allocation issues
(return value of 0).
The attached patch was tested by myself, Torsten, and Rich, and was
found to resolve the problem in call cases.
