This packet timeout prevents system entering suspend.
This 500ms timeout is too long, which will slow
resume/suspend cycle in WiFi wakeup, so reducing it to 100ms.
Also, BRCM confirmed that it's safe to remove this timeout.

- When user space app tried to call a syscall

it dumps the process name, syscall number

- This leads to kernel_warning GVS failures.
- Since, the regs dump is just for the

unmet direct dependencies (SMP && HOTPLUG)
Despite zap being costly, zap was used as nvmap wants to be able
to disallow access to handle on any cpu access. Now this is made
available through a fixup_prot handler so a less costly operation
like mprotect can be used.
During NVMAP_PAGES_RESERVE operation, use mprotect to set
permissions to __P000.
On NVMAP_PAGES_UNRESERVE, just modify the vm_flags to allow nvmap
know about the first cpu access using fixup_prot handler and do
necessary cache operations. If fixup_prot returns true, the pte
will be fixed up with proper protections.
NVMAP_PAGES_INSERT_ON_UNRESERVE fixes up the pte protections as well.
Rename NVMAP_PAGES_ZAP_AND_CLEAN as NVMAP_PAGES_PROT_AND_CLEAN,
this is same as doing a NVMAP_PAGES_RESERVE followed by
NVMAP_PAGES_UNRESERVE.
fixup_prot handler is added to be able to notify nvmap
about any user accesses when user ptes are marked with
_P000 protections. Nvmap allows fix up of protections
if the handle is not reserved and also performs necessary
cache flushes as applicable

video: tegra: nvmap: force handle wide reserve operations
This forces all supported reserve operations to be handle wide
operations. This will allow us to remove all zap and explicit insert
we do in nvmap. This will make us align more towards upstream.
video: tegra: nvmap: track reserve at handle level
Reserve/unreserve entire handle at once. Remove the bookkeeping
operations which kept track of reserve/unreserve per page. This
avoiding some overhead involved in both reserve/unreserve operations.
Allow driver decide if page protections can be fixed.
This allows us replace zapping vma's with mprotect calls.
Zap based solution is considerably slower than mprotect
based one and hence deviating from upstream.

iio: imu: nvi v.328 fix wake IRQ
- Some sensors require other sensors to be enabled (significant motion requires
accelerometer) which caused the setting of the ICM DMP wake IRQ to be
incorrect. Fixed by basing the ICM DMP wake IRQ setting on only the intended
enabled sensors (enabled from HAL as opposed to enabled due to dependency).
- Enable wake63 for motion_int: The GPIO_PX2 to which the MPU hw irq
is routed is currently not configured as a wake up source and because
of this when the system goes into suspend, the MPU irq is unable to
wake the system up.

iio: imu: nvi v.325 ICM DMP support
The following done to support the Invensense ICM DMP:
- Add ability for AUX client to select the AUX port.
- Add efficient AUX device enable/disable.
- Add sensor accuracy.
- Add DMP initialization after AUX device registers.

iio: imu: nvi v.324 Fix wake up IRQ
- The DMP IRQ mode is selected by which sensors are enabled which is tracked
by a bit mask. The bug was that this bit mask was not clearing the bit
pertaining to a disabled sensor and hence the DMP was programming the
incorrect IRQ mode when suspending.
