When a system is entering RPM assisted sleep, the NOACK messages are
not accounted in preventing such sleep modes as no driver is waiting
on it. In such scenarios, some active messages could still be in the
Apps RX buffer which reduces the number of outstanding sleep messages.
Fix by accounting for NOACK messages while flushing sleep set requests
and ensuring that they are read before sending any sleep set requests.
The original changes were reverted to address issues with SMD transport.
This change includes fixes from earlier squashed into a single commit.

This deliberately changes the behavior of the per-cpuset
cpus file to not be effected by hotplug. When a cpu is offlined,
it will be removed from the cpuset/cpus file. When a cpu is onlined,
if the cpuset originally requested that that cpu was part of the cpuset, that
cpu will be restored to the cpuset. The cpus files still
have to be hierachical, but the ranges no longer have to be out of
the currently online cpus, just the physically present cpus.

Interrupt Storm is observed on the APPS side, when PCIe link down is
simulated, as FW keeps generating interrupts to host, as it's not aware
of the PCIe link down.
When PCIe link down is identified, wlan platform driver schedules work
to start recovery. During Recovery we cut down power to QCA6174, which
stops the interrupt storm. During the window where platform driver
schedule work and the work actually gets schedules, interrupt storm
happened and the APPS triggered watchdog.

Fix issues raised by static analyzer:
1. initialize "retval" before being returned from the driver function.
2. Check return value of the function create_singlethread_workqueue()
and return -ENOMEM if it failed. If creation of the workqueue
failed, then both queue_work() and queue_delayed_work() calls will
later crash, as they expect the workqueue pointer to be a non-NULL
value. Also add clean-up code for this.
3. check return value of the snprintf() call as array 'buf' of size
16 may use index value(s) 16...20.

vdd-wlan-xtal-aon-supply(LD0-4) need to be voted by cnss platform
driver to keep wlan XO(LDO-5) ON during APPS suspend on mdmcalifornium
platforms when wlan is turned ON as per Power UP sequence. Currently
LDO-4 is only voted by USB driver when USB is connected. On removing USB,
LDO-4 is turned off resulting LDO-5 turned off.
When WLAN is turned on removing LDO-5 vote resulted in beaconing failures
on mdmcalifornium platforms. Hence add a dummy vote to LDO-4 when WLAN is
turned ON.

Because of a change in the underlying bus driver, the secure touch
layer in the input drivers is now required to control directly the
clocks which are needed during the touch sessions. The clocks which
are associated with the underlying I2C bus are clk_gcc_blsp1_ahb_clk
and clk_gcc_blsp1_qup3_i2c_apps_clk. These clocks are turned on/off
when the secure touch session is started/ended.

qseecom_send_modfd_cmd converts ION buffer's virtual address to
scatter gather(SG) list and then sends them to TA by populating
SG list into message buffer. As the physical memory address in
SG list is used directly by TA, this allows a malicious TA to
access/corrupt arbitrary physical memory and may lead to the
process gaining kernel/root privileges. Thus, make changes to
have the QSEEComm driver passing a list of whitelist buffers
that is allowed to be mapped by TA, and the QSEE kernel, in turn,
should add checks to the register_shared_buffer syscall to make
sure the shared buffers an application is mapping falls within
one of these whitelist buffers.
