ae282d2c22 video: tegra: nvmap: Fix error pointer dereference 
In nvmap_try_duplicate_by_ivmid(), the return pointer from
nvmap_duplicate_handle() is getting dereferenced without checking
whether the pointer is error or valid. This is causing kernel panic.
Fix this by checking if the return pointer is invalid then return error.

a588f61b8e video: tegra: nvmap: Remove use of bitmap_allocate_region 
NvMap is using bitmap_allocate_region while doing allocation from IVM
carveout. It expects size to be always power of 2, this is resulting
into memory shortage. Better way to handle this is to use the function
bitmap_find_next_zero_area which expects bitmap size rather than order.
Then use bitmap_set to set the allocated bits from the bitmap.
Similarly, while freeing the buffer, use bitmap_clear instead of
bitmap_release_region.

e3a44ab6e8 video: tegra: nvmap: Fix kmemleak issue 
get_task_struct increment the ref count over task struct, and it will be
decremented as part of put_task_struct. task_struct won't be freed
unless it's refcount becomes 0. Hence the missing put_task_struct in
nvmap code was resulting into kmemleak. Fix it by add this missing call.
Also, mutex_unlock was missing in one of the return path, add it.

85f7def3a6 nvmap: Don't free pages while freeing subhandle 
This patch fixes the following issues:
- When the handle associated with the sub-buffer is freed, the call to
the nvmap_page_pool_fill_lots is made, which would free the pages when
the refcount on the pages is > 1, even though the main handle is not
freed, hence add a check for sub-handle.
- In cpu unmap code, list_for_each_entry is used for iterating over the
vma list and in the same loop list_del is aldo being called, this can
lead to undefined behavior, instead use list_for_each_entry_safe which
is safe against removal of list entry.
- Mutex of sub-handle is not initialized, fix it by initializing it.
- Set error value when handle creation failed.

abb244025f nvmap: Fix coherency issues while creating subhandle 
Make sure that all handles, from which sub-buffer handle needs to be
created, have same cache coherency, are of type RW, not created from VA.
Set the cache coherency of the sub-buffer handle same as the cache
coherency of the main handles, so that explicit cache flush is not
needed during vma fault.

ad02c6afa5 nvmap: Use same nvmap client for namespaces in a process 
Some of the libraries may be linked into different namespaces, but they
belong to same process. So each namespace can open the /dev/nvmap node
and call nvmap ioctls, instead of reusing the already opened /dev/nvmap
FD. Because of this, memory handles created by one namespace can't be
used by other namespaces, even though they belong to same process.

Fix this issue by following:
- When /dev/nvmap node is opened, check if there is already any nvmap
client with same pid, if yes use that client; otherwise, create new
nvmap client.
- Track the number of namespaces via count field.
- When /dev/nvmap node is closed, destroy the nvmap client only when
count reaches to 0.

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.

during carveout creation, buffer allocation and buffer release. Due to
cache flush for entire carveout at creation time, nvmap takes ~430 ms

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.

<snip>

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

2. pass __iomem type pointer to io framework.
