Haven Resource Manager API defines a simple console for VM log sharing.
This patch adds support for this console with the HVC console framework.
It is possible to use this driver as the "primary VM" to listen to other
VM console logs or as the "secondary VM" to send logs to the "primary
VM". For the latter, CONFIG_HVC_HAVEN_CONSOLE must be set to y.

Smmu driver takes a vote on CX gdsc before calling the kgsl pagefault
handler. If there is contention for device mutex in this path and the
dispatcher fault handler is holding this lock, trying to turn off CX
gdsc will fail during the reset. So to avoid blocking here, try to
lock device mutex and return if it fails.

Based on Kirill's patch [1].
Currently, faultaround code produces young pte. This can screw up
vmscan behaviour[2], as it makes vmscan think that these pages are hot
and not push them out on first round.
During sparse file access faultaround gets more pages mapped and all of
them are young. Under memory pressure, this makes vmscan swap out anon
pages instead, or to drop other page cache pages which otherwise stay
resident.
Modify faultaround to produce old ptes if sysctl 'want_old_faultaround_pte'
is set, so they can easily be reclaimed under memory pressure.
This can to some extend defeat the purpose of faultaround on machines
without hardware accessed bit as it will not help us with reducing the
number of minor page faults.
Making the faultaround ptes old results in a unixbench regression for some
architectures [3][4]. But on some architectures like arm64 it is not found
to cause any regression.
unixbench shell8 scores on arm64 v8.2 hardware with CONFIG_ARM64_HW_AFDBM
enabled (5 runs min, max, avg):
Base: (741,748,744)
With this patch: (739,748,743)
So by default produce young ptes and provide a sysctl option to make the
ptes old.

The memory regions managed by carveout heaps are provisioned to
the heaps at boot, and once a memory region is bound to a heap,
the binding of heap to memory region is immutable. In some cases,
it might be desireable to assign the memory region for a carveout
heap on demand.
Thus, add support for dynamic carveout heaps. Dynamic carveout heaps
are initialized as empty heaps (i.e. they have no memory associated
with them) and must have memory added to them prior to use. Dynamic
heaps can also have memory removed from them, so add support for both
of these functionalities as well.

Currently when brightness is zeroed-out for a flash/torch device its
"configured" flag is set to false. Hence the flash/torch device is
ignored when its switch is disabled. This leads to the corresponding
LED channel left enabled. Fix this by setting "configured" flag to
false only when led strobe is de-asserted.

This change adds snapshot of usb audio qmi service related files.
A remote entity communicates with usb audio qmi server to enable
or disable particular audio stream on enumerated usb audio device.
This offloads ISOC data transfer operations to remote entity and
allows apps processor to go to power collapse more frequently for
better power saving.
This snapshot was taken as of msm-4.19 commit 3ecc1a5c8726 ("sound:
usb: Don't bail out if qmi_send_indication fails"). In addition,
several updates were made for the current kernel to be compatible
with the GKI ABI, such as making direct calls to APIs exported by
the XHCI driver as well as other minor checkpatch fixes.
