A CPU that is isolated needs to have its timers migrated off to
another CPU. If while migrating timers, there is a running
timer, acquiring the timer base lock after marking a CPU as
isolated will ensure that:
1) No more timers can be queued on to the isolated CPU, and
2) A running timer will finish execution on the to-be-isolated
CPU, and so will any just expired timers since they're all
taken off of the CPU's tvec1 in one go while the base lock
is held.
Therefore there is no apparent reason to wait for the expired
timers to finish execution, and isolation can proceed to migrate
non-expired timers even when the expired ones are running
concurrently.
While we're here, also add a delay to the wait-loop inside
migrate_hrtimer_list to allow for store-exclusive fairness
when run_hrtimer is attempting to grab the hrtimer base
lock.

If the new governor fails to start, switch back to old governor so that the
devfreq state is not left in some weird limbo.

Add more information to the debugfs kgsl/proc/<pid>/mem which
will allow memtrack to correctly assign allocated ion buffer
memory to a process. The additional columns show the number of
kgsl_mem_entries which have a usage of egl_image (or) egl_surface.
When attaching a dma_buf to kgsl, use the dma_buf_attachment's
(void*)priv to point back to the kgsl_mem_entry. This makes it
possible to iterate through all attachments on a dma_buf and
gather statistics from each kgsl_mem_entry associated with the
dma_buf.

Convert most of the pmfalcon stub-regulator devices to a
rpm-smd-regulator devices. This ensures that requests made for
these regulators are aggregated by the RPM processor along with
the requests from other processors.
Also, add a dummy gfx_vreg_corner regulator until the CPR node
is added.
While at it, rename all regulators names and add pm/pm2 prefix
to differentiate between regulators on multiple supported PMICs.
Also update all clients with new regulator phandles.

comparison to msleep. This helps in reducing the

Add a quirk to set LMLOADKILLDIS bit in A5XX_VPC_DBG_ECO_CNTL
and clear LMLOADKILLDIS bit in A5XX_HLSQ_DBG_ECO_CNTL registers.
This is done to avoid a VPC corner case with local memory(LM)
which leads to corrupt internal state on A540 and its derivatives.

Embedded tputs depend on WAN RX desc size, but, every target
has its own limitations of memory and embedded tputs goals.
So, add parameter to configure WAN RX desc size through device tree.

Based on the hardware documentation, update the IMA error
handling and clear sequence. In addition, check for DMA errors
and clear it before SRAM transactions begin. Also, check for IMA
hardware status to run the IMA clear sequence during ima_init and
not just based on IMA exception status alone. This is to help
with FG SRAM access to resume again properly in case of an error
encountered.
