Memory translation fault occurs when incorrect memory
is accessed. To avoid translation fault, do not access
message memory which is not initialized.

Move the input validation for the connector's HDR support
before calling the API to set the infoframe rather than within
the API itself.
This helps to avoid redundant checks and logging.

During first time boot up WLAN Platform driver allocate
1 MB MSA0 Memory region. This region may be adjacent to
other regions that also requires access control, due to
that TZ will merge the two sections into one single resource
group. During this Q6 will lose access to memory region causing
a NOC Error. To avoid use fixed memory region for WLAN MSA0
memory.

The size of the settings copied from userspace, is directly checked
in msm_cci_data_queue with CCI_I2C_MAX_WRITE. This might cause
out of bound access in function msm_cci_data_queue as the max size is
MAX_I2C_REG_SET. Hence adding check on the size in flash driver itself.

The information in /sys/kernel/debug/page_owner includes the migratetype
of the pageblock the page belongs to. This is also checked against the
page's migratetype (as declared by gfp_flags during its allocation), and
the page is reported as Fallback if its migratetype differs from the
pageblock's one. t This is somewhat misleading because in fact fallback
allocation is not the only reason why these two can differ. It also
doesn't direcly provide the page's migratetype, although it's possible
to derive that from the gfp_flags.
It's arguably better to print both page and pageblock's migratetype and
leave the interpretation to the consumer than to suggest fallback
allocation as the only possible reason. While at it, we can print the
migratetypes as string the same way as /proc/pagetypeinfo does, as some
of the numeric values depend on kernel configuration. For that, this
patch moves the migratetype_names array from #ifdef CONFIG_PROC_FS part
of mm/vmstat.c to mm/page_alloc.c and exports it.
With the new format strings for flags, we can now also provide symbolic
page and gfp flags in the /sys/kernel/debug/page_owner file. This
replaces the positional printing of page flags as single letters, which
might have looked nicer, but was limited to a subset of flags, and
required the user to remember the letters.
Example page_owner entry after the patch:
Page allocated via order 0, mask 0x24213ca(GFP_HIGHUSER_MOVABLE|__GFP_COLD|__GFP_NOWARN|__GFP_NORETRY)

A race condition between queueing and processing the disable_work
instances results in having a work instance in the queue and the
deferred_disables variable of regulator device structure having a
value '0'. If no new regulator_disable_deferred() call later from
clients, the deferred_disables variable value remains '0' and hits
BUG() in regulator_disable_work() when the queued instance scheduled
for processing the work.
The race occurs as below:
Core-0 Core-1
..... /* deferred_disables = 2 */ .....
..... /* disable_work is queued */ .....
..... .....
regulator_disable_deferred: regulator_disable_work:
mutex_lock(&rdev->mutex); .....
rdev->deferred_disables++; mutex_lock(&rdev->mutex);
mutex_unlock(&rdev->mutex); .....
queue_delayed_work(...) count =rdev->deferred_disables;
..... rdev->deferred_disables = 0;
..... .....
..... mutex_unlock(&rdev->mutex);
..... .....
..... return;
..... .....
/* No new regulator_disable_deferred() calls from clients */
/* The newly queued instance is scheduled for processing */
..... .....
regulator_disable_work:
.....
mutex_lock(&rdev->mutex);
BUG_ON(!rdev->deferred_disables); /* deferred_disables = 0 */
The race is fixed by removing the work instance that is queued while
processing the previous queued instance. Cancel the newly queued instance
from disable_work() handler just after reset the deferred_disables variable
to value '0'. Also move the work queueing step before mutex_unlock in
regulator_disable_deferred().
Also use mod_delayed_work() in the pace of queue_delayed_work() as
queue_delayed_work() always uses the delay requested in the first call
when multiple consumers call regulator_disable_deferred() close in time
and does not guarantee the semantics of regulator_disable_deferred().
