The changes modify the callback registration and dispatch
on a synx object for non-blocking wait.
The userspace callback payloads are maintained in UMD driver
and unique id passed by client is saved in callback entry
to manage the callback. These callbacks are distinguished
with the callbacks registered by kernel clients through the
default callback function registered.
This provides uniform handling (in most cases) for callbacks
registered by userspace and kernel clients.
The change also allows signaling with CANCELLED state.

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.
