Now that there is a "real" solution for exfat in the vfs tree queued up
to be merged in 5.7-rc1 the "old" exfat code in staging can be removed.
Many thanks to Valdis for doing the work to get this into the tree in
the first place, it was greatly appreciated.

If multiple rpmsg are sent, it is possible there will be a
mismatch of completions. If requester sends rpmsg A and B,
it is possible the completer sees only rpmsg B. Once completer
sends ACK/NACK for rpmsg B, the requester may interpret, it is
for rpmsg A if the timeout for it has not expired. Therefore,
serialize the send of rpmsg and its completion to avoid this
possible race by moving rpmsg lock after command completion.

By default when ep0 gets enable, current code SET XFER resource command
for all USB endpoints excluding USB GSI endpoint. SET XFER resource
command shall fail if all resources are allocated. All allocated transfer
resources are resets in controller when DEPXFERCFG cmd is send with ep0
with value as 2 OR when controller is being peformed power on reset or
being restarted (i.e. device initiated disconnect and reconnect).
Consider case as below:
a. USB enumerated
b. USB bus suspend
c. USB bus reset
d. USB connect done
e. USB set_config() (set_alt())
f. Reenable all USB endpoint and resize tx fifo for it except ep0 and ep1
g. USB GSI endpoint operation (EP_OP_CONFIG) is sending SET XFER RESOURCE
which is failing as all resources are already allocated.
ep0 is disabled while clearing run stop and re-enabled when setting run
stop. For USB device mode we know that ep0 enabling is prerequisite before
setting run stop. Hence let ep0 enabling takes care of reallocating
transfer resources for all endpoint including USB GSI endpoints.

MADV_FREE clears pte dirty bit and then marks the page lazyfree (clear
SwapBacked). PPR increments ISOLATE_FILES count, then isolates page and
invokes a reclaim. Inbetween if this lazyfreed page is touched by user then
it becomes dirty. PPR in shrink_page_list in try_to_unmap finds the page
dirty, marks it back as PageSwapBacked and skips reclaim. As PageSwapBacked
set, PPR identifies the page as anon and decrements ISOLATED_ANON, thus
creating isolated count mismatch.
This results in too_many_isolated() check causing delay in reclaim. Skip
reclaiming lazyfreed pages in PPR path.

Currently, updating USB type only depends on USB status change
notification from the charger firmware. During a reboot with USB
connected, there is a chance that a USB power supply notification would
have been sent by the charger firmware little earlier even before the
battery charger driver was ready to handle it. Hence it would've got
missed and USB type is not updated properly. Fix it by scheduling
usb_type_work once the driver probes.

The SMMU driver will vote for the resources it needs before performing
a particular operation, and will remove its votes after the operation
is complete.
When power resources are not currently enabled by other drivers,
the SMMU driver's requests to enable its devices' power resources
go through the slow paths where the hardware power resources
get turned on. So, in a scenario where the SMMU driver is constantly
performing work and having to toggle the state of the power resources,
the SMMU driver operations take more time.
On GKI, the upstream implementation of the IOMMU page table management
code is used, which doesn't have the optimizations we have downstream,
which improve the performance of the SMMU driver when unmapping memory.
The GPU can go into slumber if it is not active, and can relinquish its
votes for the power resources that the SMMU driver votes for when
unmapping memory. This requires the SMMU driver to take the slowpath
of enabling all of these power resources and then disabling them
on every call to unmap memory, which can incur a considerable amount
of delay.
This delay, along with the usage of the unoptimized IOMMU page table
management code in GKI results in slow unmap calls.
Thus, add support for the SMMU driver to never remove its power votes,
so that it doesn't have to spend time voting for power resources while
it is operating.
