In Android-M, below change in bionic was introduced
https://android-review.googlesource.com/122131
Which caused lot of SELinux denials to be logged regarding

There is quite a lot of module_request denials when any 32bit
executable is executed.

Even though 1MB is reserved for descriptor table in IDMAC,
the dw_mmc host driver is allowed to receive only maximum
128KB block length in one request. This is caused by setting
improper max_blk_count. It needs to be e adjusted so that
descriptor table is used fully. It is found that the performance
is improved with the increased the max_blk_count.

(cherry picked from commit 60b9dd6043fdc26860d850c364fd92b1f4e170fc)
Use the ATTR_FILE attribute to distinguish between truncate()
and ftruncate() system calls. The two other cases where
do_truncate is called with a filp (and therefore ATTR_FILE is set)
are for coredump files and for open(O_TRUNC). In both of those cases
the open permission has already been checked during file open and
therefore does not need to be repeated.
Commit 95dbf73931 ("SELinux: check OPEN on truncate calls")
fixed a major issue where domains were allowed to truncate files
without the open permission. However, it introduced a new bug where
a domain with the write permission can no longer ftruncate files
without the open permission, even when they receive an already open
file.

This change fixes a problem where reboot on Android panics the kernel
almost every time when file systems are mounted over loop devices.
Android reboot command does:
- sync
- echo u > /proc/sysrq-trigger
- syscall_reboot
The problem is with sysrq emergency remount R/O trying to remount-ro
in wrong order.
since /data is re-mounted ro before loop devices, loop device
remount-ro fails to flush the journal and panics the kernel:
EXT4-fs (loop0): Remounting filesystem read-only
EXT4-fs (loop0): previous I/O error to superblock detected
loop: Write error at byte offset 0, length 4096.
Buffer I/O error on device loop0, logical block 0
lost page write due to I/O error on loop0
Kernel panic - not syncing: EXT4-fs panic from previous error
The fix is quite simple. In do_emergency_remount(), use
list_for_each_entry_reverse() on sb list instead of list_for_each_entry().
It makes a lot of sense to umount the file systems in reverse order in
which they were added to sb list.

When the task is terminated, the cpu_power for that particular task is
added to the terminated tasks. cpu_power is set to ULLONG_MAX at this
point to avoid double accounting of the power. It is possible that before the
task releases all the resources, cpu reschedules the task or a timer
interrupt is fired. At this point we will try to add the additional time
to the process, which will cause the accounting to be skewed. This
avoids the case where we change the cpu_power when it is already set to
ULLONG_MAX.
