9045984efb nvmap: Remove use of __dma_flush_area 
__dma_flush_area is defined in downstream, we need maintenance effort
when kernel version is upgraded. Instead, use arch_invalidate_pmem
function provided by the upstream.

596156cc4b nvmap: Register nvmap device towards end of probe 
On TOT, in nvmap probe function, platform_set_drvdata is called after
misc register. So nvmap node is created and clients can open it even
before platform driver data is set. Because of which, the call to
dev_get_drvdata returns NULL and BUG_ON condition is hit. Move misc
register call towards end of the nvmap probe, so that /dev/nvmap is
exposed once all initilization is completed.
As misc register being moved to end of probe, the functions which are
called before misc register and which make use of dev_user field from
nvmap_device for calling dev_err/dev_info function will see the dev
field as NULL. Hence replace such calls with pr_err/pr_info.

92f34279ba nvmap: Keep cache flush at allocation time only 
On TOT, in case of carveouts, nvmap performs cache flush operation
during carveout creation, buffer allocation and buffer release. Due to
cache flush for entire carveout at creation time, nvmap takes ~430 ms
for probe. This is affecting boot KPIs.
Fix this by performing cache flush only at buffer allocation time,
instead of carveout creation and buffer release. This is reducing nvmap
probe time to ~0.69 ms.

78db0d7c41 tsec: Conditionally turn off clock in suspend 
Problem:
=======
In current implementation of tsec_poweroff, tsec clock is getting
turned off unconditionally.

During suspend-resume operation, there is an issue in MB1 as
explained in bug 3796711 (comment 16). Due to this, when
tsec_poweroff function is called for second suspend operation,
tsec clock is turned off even when the power state variable
"pdata->power_on" is not set to true or 1.

This causes the following warning from clock driver highlighting
that tsec clock is already disabled.

Solution:
========

There is a check present in tsec_poweroff function to conditionally
call tsec_prepare_poweroff only if TSEC is powered on. Use the
same check to conditionally call tsec_disable_clk

983d45ff71 video: tegra: virt: switch to IVC IRQ 
Handling IVC notifications using the callback method is
problematic when trying to handle the IVC reset protocol.
The comm framework now handles IVC IRQs locally.

7328f57280 video: tegra: virt: add virtualization interfaces 
Tegra graphics virtualization (host1x syncpoint and gpu) is now
exposed to client drivers (nvhost and nvgpu). These interfaces
rely on a communication framework to communicate with the server
driver that actually implements the back-end routines.

354ef0dbe0 drivers: Use runtime debugfs check 
When kernel command line debugfs=off is specified instead of
disabling CONFIG_DEBUG_FS in defconfig to disable Debug-FS,
debugfs functions like debugfs_create_dir will fail.

Use function debugfs_initialized() to check if debugfs
functionality is enabled before calling any debugfs functions.

This allows us to by-pass debugfs initialization if debugfs
is not enabled.
