Qmuxd bridge daemon is opening /dev/gps before USB enumerated with
USB composition having GPS interface as part of it. This daemon
performs EP_LOOKUP ioctl and encounters failure. It keeps retrying
for some iterations, and later goes into sleep and doesn't perform
any IOs. This results into no GPS related IOs between daemon and
host side QMUXD driver. Hence this change sends zero length packet
for MBIM (as QBI also faces same issue) and GPS interface when
USB cable is connected and those interfaces are part of USB
composition. Both QBI and Qmuxd bridge daemon are now wait for zero
length packet as indication for change in USB cable status, and
queries using GSI_MBIM_GPS_USB_STATUS IOCTL (newly added). Based on
this IOCTL related response, both daemons performs read/write with
created control devices.

gps usb functionality is implemented using qmi packets.
User space entity sends and receives QMI packets using
misc device named /dev/gps.

The inclusion of draw object flag for msm_perf_events_update.
Since user-space thread is triggered based on kgsl events
this will be vital to distinguish the events based on frame
states and prevent undesirable user-space thread wake-ups.

Hyp uart is default disabled from ABL now. There is no need of
CONFIG_HH_DISABLE_UART option anymore. Hyp uart now can be controlled
using DEBUG_FS interface.

When memory block is logically offlined, it is still part of System RAM but
is inactive, and can be made active or Onlined anytime.
Take totalram snapshot to include offlined memory in Memtotal.
This method avoids taking device_hotplug lock to meminfo.
Fixes: dc00b6d99a ("proc/meminfo: include offlined region for mem total")

With QCOM quirks, the invalidations are agrregated to reduce map/unmap
time. In absenence of CONFIG_QCOM_IOMMU_TLBI_QUIRKS enabled, the map/unmap
latency impact time critical usecases. Hence defer TLB invalidation when
CONFIG_QCOM_IOMMU_TLBI_QUIRKS is not enabled.

In ssr handling of remote subsystem down, all rpmsg devices are removed
for that edge. If at the same time ssr down is received for other remote
subsystem, it may try to notify already down remote and end up using
invalid rpmsg device which causes use after free.
Store device state in ssr context and update this with holding a lock.
SSR notification function should also use the same lock and perform
check for validity of rpmsg device.

in use of stale device pointer in ssr callback function.
Now incrementing refcount inside ssr callback function to
prevent release of rpmsg device.
