Do not call copy_from_user in ioctl handler if CONFIG_COMPAT
is defined.
In 64 bit kernel and 32 bit userspace, ioctl call invokes
compat_ioctl. First copy_from_user is done in compat_ioctl then
pointer is passed to unlocked_ioctl for actual processing. In
unlocked_ioctl again copy_from_user is called on kernel pointer.

The 11ad spec requires 11ad devices to be able to receive 8KB
packets over the air. Currently this is only possible by
loading the driver with mtu_max=7912 but this also forces
a smaller block ACK window size which reduces performance
for stations which transmit normal sized packets (<2KB).
Fix this problem as follows:
1. Add a module parameter rx_large_buf that when set,
will allocate 8KB RX buffers regardless of mtu_max
setting.
2. When receiving block ACK request agree to any window
size not above our maximum, regardless of the mtu_max setting.
This means if the other side transmits small packets (2KB)
it can still set up block ACK with a large window size,
and get better performance.

Allow the user to allocate and use secured buffer objects. Secured
buffer objects are suitable for use as a write target while the GPU
is in secure mode. They work exactly like regular buffers except
Secure buffers cannot be mmap()ed.

Outside clients (such as the display or GPU) may import a dmabuf
and need to figure out if it is secure so that it can be handled
accordingly. In an ideal world this would be part of the generic
dma-buf structure but until then we can assume that the only outside
source of dmabuf-ified secure buffers is Ion so add a function to
directly query the status of the buffer from Ion.
ion_dma_buf_is_secure() returns true if the dmabuf was created
by Ion and was created from a secure heap.

A5XX targets support GPU rendering on secured surfaces by going
into a special secure mode to execute the commands. In secure mode
GPU rendering can only write to secure buffers that have been mapped
in an appropriately secured pagetable. In secure mode the GPU can read
both secure and unsecure buffers and the CP engine can only access
unsecured buffers (so commands do not need to be secure).
Secure buffers virtual addresses must fall into a specific range; this
is the clue to the GPU that it should use the secure pagetable
instead of the regular one. For A5XX targets that range will start
at 0xC0000000 and be 256MB in size. All secure buffers in all processes
share the same pagetable.
Add a secure address space for A5XX targets and automatically trigger
into secure mode if any buffer in the submission is marked as secure.

Without is_enabled function support, regualtor framework treats
it as an always on regulator and does not invoke the regulator enable
function call. Hence, add support for it.
Also, define a parent supply ("vin") for the regulator. This parent
can be used to pin-control the regulator. While at it, change the initcall
level to subsys_init. so that the driver registers after the parent supply
("vin" - provided by fixed-regualtor).
