If video fmts are not same in LK and kernel,
then splash will be turned off, clks need to be put off
which are switched on during probe.

Put the SMMU register range in protected mode to shield them from

msm: kgsl: Protect CP_STATE_DEBUG_INDEX

Put CP_STATE_DEBUG_INDEX and CP_STATE_DEBUG_DATA under protection
to keep it from being written from an IB1. Doing so however opens
up a subtle "feature" in the microcode: memory read opcodes turn off
protected mode in the microcode to do the read and then turns it
back on regardless of the initial state. This is a problem if the
memory read happens while protected mode is turned off and then we
try to access a protected register which then complains and goes boom.

To account for this irregularity explicitly turn back off protected
mode in all the places where we know this will be a problem.

qseecom: Add support to handle multiple app load & unload

Media server is associated with multiple apps on TZ-side.
Unloading a single app for clean up is not enought. QSEECOM
needs to handle the app load & unload of multiple apps
associated with the client. During app_load & app_unload
along with app_id, app_name should also be checked. Besides,
keymaster will not be unloaded.

ARM: fix executability of CMA mappings

The CMA region was being marked executable:

0xdc04e000-0xdc050000           8K     RW x      MEM/CACHED/WBRA
0xdc060000-0xdc100000         640K     RW x      MEM/CACHED/WBRA
0xdc4f5000-0xdc500000          44K     RW x      MEM/CACHED/WBRA
0xdcce9000-0xe0000000       52316K     RW x      MEM/CACHED/WBRA

This is mainly due to the badly worded MT_MEMORY_DMA_READY symbol, but
there are also a few other places in dma-mapping which should be
corrected to use the right constant.  Fix all these places:

0xdc04e000-0xdc050000           8K     RW NX     MEM/CACHED/WBRA
0xdc060000-0xdc100000         640K     RW NX     MEM/CACHED/WBRA

ARM: dma-mapping: don't allow DMA mappings to be marked executable

DMA mapping permissions were being derived from pgprot_kernel directly
without using PAGE_KERNEL.  This causes them to be marked with executable
permission, which is not what we want.  Fix this.
