Userspace processes often have multiple allocators that each do
anonymous mmaps to get memory. When examining memory usage of
individual processes or systems as a whole, it is useful to be
able to break down the various heaps that were allocated by
each layer and examine their size, RSS, and physical memory
usage.
This patch adds a user pointer to the shared union in
vm_area_struct that points to a null terminated string inside
the user process containing a name for the vma. vmas that
point to the same address will be merged, but vmas that
point to equivalent strings at different addresses will
not be merged.
Userspace can set the name for a region of memory by calling
prctl(PR_SET_VMA, PR_SET_VMA_ANON_NAME, start, len, (unsigned long)name);
Setting the name to NULL clears it.
The names of named anonymous vmas are shown in /proc/pid/maps
as [anon:<name>] and in /proc/pid/smaps in a new "Name" field
that is only present for named vmas. If the userspace pointer
is no longer valid all or part of the name will be replaced
with "<fault>".
The idea to store a userspace pointer to reduce the complexity
within mm (at the expense of the complexity of reading
/proc/pid/mem) came from Dave Hansen. This results in no
runtime overhead in the mm subsystem other than comparing
the anon_name pointers when considering vma merging. The pointer
is stored in a union with fieds that are only used on file-backed
mappings, so it does not increase memory usage.

Add separate kernel memory mapping for GPU shader memory.
Previously, both the register and the shader memory were mapped
as one entity, with the mapping length being equal to combined
size of register memory and shader memory. Now, we separate the
shader memory mapping to help in cases of GPU devices where the
shader and register memory may not be adjacent. This helps to
dump the shader memory in the postmortem snapshot. By having a
separate mapping for shader memory, the snapshot dump routine
simply reads in the shader memory range specified and dumps.

(1) ISP interface(ISPIF) sits between sensor(CSID) and ISP.
It's responsible to mux sensor's output path to
ISP input path. ISPIF driver contains two parts, i.e.,
user space driver and kernel driver. The kernel driver is
mainly for register write and read.
(2) Image signal processing(ISP) driver's responsiblity is to
processed the sensor's raw image to generate the YUV image
for rending/video encoding and snapshot. ISP driver has
following main functional blcoks:
- Image bus(AXI) management and configuration
- ISP processing pipeline configuration and run time update
- ISP input interface(CAMIF) configuration
- Image buffer management
- ISP interrupt handling
- ISP kernel event notification to user space
- ISP hardware start/stop state machine.

In order to keep card endurance, it is best not to check the need for
BKOPS every time the MMC is idle.
However, the decision when to check the card need for BKOPS according
to number of changed sectors doesn't fit all cards sizes. Therefore,
the check for BKOPS need is based on percentages of changed sectors
of the card size.
In order to assure that BKOPS will be triggered again in case it was
interrupted, the accumulated number of changed sectors is cleared only
in case BKOPS was completed without interruption.

around an issue seen where setting the prog bit of a core's ETMCR

set thereby triggering the "timeout while setting prog bit"
warning. Subsequently performaing a manual ETB flush as part of

With 8974, bandwidth requests are exceeding integer size.
Update ab and ib to ensure values over 4Gbps can be requested.
For 64-bit support, there are four changes in this patch:
Changes in the bus driver structures and functions to
update ab and ib values to uint64.
Updates in client drivers to ensure that the bus APIs
are called with the right types.
Updates to the device-tree. Device-tree nodes don't
provide a clean mechanism to read a combination of u32
and u64 variables within the same property name. So, the
ab and ib values must be specified in kbps instead of
bytes/sec from the device tree. The bus driver function
will convert the ab and ib values read from device-tree
to Mbps.
Change the existing property names to make them consistent
with the convention used by the new property name, which
abides to the Device Tree convention.

The trigger for enabling the write packing is managing to pack several

the packing can be configured via sysfs by writing the required value to:
/sys/block/<block_dev_name>/num_wr_reqs_to_start_packing.
The trigger for disabling the write packing is fetching a read request.

The PON module supports various reset sources (physical pins)
such as KPDPWR, RESIN, RESIN+KPDPWR. These pins can be configured
for different reset types (such as warm, soft, hard) and can also
be used as push buttons (keys).
In the push-button configuration these pins act as gpios, only
reporting the state on the line (high/low) and no additional
pon based configuration being done in the hardware or software.
They can be used for generic buttons (such as volume up/down,
directional keys)

The documentation incorrectly specifies 'select' instead of
'src-select'. Update this to be consistent with the driver.

On some regulator hardware, the values read on SPMI offset 0x4 (type)
and 0x5 (subtype) are incorrect. Add a new optional property called
qcom,force-type that allows a user to override the hardware values
with values supplied in the Device Tree.
