Make the kmem debugging prints much more easily usable. Previously the
prints would only take effect if the full tracking was enabled:
CONFIG_NVGPU_TRACK_MEM_USAGE
However, there are many times when just the debug prints would be nice
to have by simply setting the log mask bit in the log mask.
echo 0x80000 > /sys/kernel/debug/<gpu>/log_mask
Also this change now uses the real nvgpu_log() function instead of the
legacy nvgpu_dbg() function. This makes the logging appear with proper
GPU printing as well.

Add a function to check if an nvgpu_mem is allocated (valid) or not.
Also fix possibly leaked state in nvgpu_mems when they fail to
allocate.
Also ensure that in the case of a failure to allocate no state is
accidentally leaked to the caller. This should hopefully make it
less likely that a caller thinks a buffer that failed to allocate
is actually allocated.

NVGPU_SUBMIT_GPFIFO_FLAGS_RESCHEDULE_RUNLIST is only used by realtime
priority EGL context, which checks for CAP_SYS_NICE during context
creation in userspace, so it wasn't secure against unprivileged program
spoofing submit ioctl with this flag to stall GPU progress of others.
This flag does increase duration of submit by approx 16us,
mostly due to register accesses and PMU FIFO mutex.

Allow userspace to control directly the PTE kind for the mappings by
supplying NVGPU_AS_MAP_BUFFER_FLAGS_DIRECT_KIND_CTRL for MAP_BUFFER_EX.
In particular, in this mode, the userspace will tell the kernel
whether the kind is compressible, and if so, what is the
incompressible fallback kind. By supplying only the compressible kind,
the userspace can require that the map kind will not be demoted to the
incompressible fallback kind in case of comptag allocation failure.
Add also a GPU characteristics flag
NVGPU_GPU_FLAGS_SUPPORT_MAP_DIRECT_KIND_CTRL to signal whether direct
kind control is supported.
Fix indentation of nvgpu_as_map_buffer_ex_args header comment.

Explicitly page align DMA memory allocations. Non-page aligned
DMA allocs can lead to nvgpu_mem structs that have a size that's
not page aligned. Those allocs, in some cases, can cause vGPU
maps to return an error.
More generally DMA allocs in Linux are never going to not be
page aligned both in size and address. So might as well page align
the alloc size to make code else where in the driver more simple.
To imlpement this an aligned_size field has been added to struct
nvgpu_mem. This field has the real page aligned size of the
allocation. The original size is still saved in size.

Fix some simple pointer arithmetic errors in the deterministic submit
path. The lockless allocator was doing a subtraction to determine the
correct offset of the element to free. However, this subtraction was
using the base address and a numeric offset - not a pointer offset. Thus
the difference computed was in bytes not in elements of the block size.
The fix is simple: just divide by the block size.
Also this modifies the debugging statement a bit so that a bit more
information is printed at more useful times.
Lastly, a pointer to numeric cast was fixed in the fence code.

The offset units in the nvgpu_pramin_access_batched() code changes
midway through the function. In the first section it is treated as
bytes but then in the while-loop iterating over the PRAMIN window
and page_alloc_chunks it becomes an offset in words.
This patch leaves the offset field in bytes and converts to words
where needed.

The call to __set_pd_level() for vidmem allocs had the wrong
length being passed in. This was a silent error since the subsequent
__set_pd_level() calls overwrote the bad mappings. However this
caused significantly more PDE/PTE writes than necessary since
each chunk could be mapped N times where N is the number of chunks
in an SGL.

In gm20b_tegra_postscale(), we use platform->railgate_lock to check if GPU is
railgated or not
But platform->railgate_lock was introduced only to prevent unrailgating in midst
of gk20a_do_idle() sequence
This lock is not the right way to check railgate status since it is still
possible to railgate GPU with this lock being held
Hence remove acquire/release of platform->railgate_lock from
gm20b_tegra_postscale()

we could still see 64K GMMU pages beeing used.
Fixed the following:
- enforce disable_bigpage in nvgpu_vm_map
- update GPU characteristics so that new clients know
whether or not big pages are enabled. For instance
this may affect how CUDA requests memory mapping.

Remove the mm.get_iova_addr() HAL and replace it with a new HAL
called mm.gpu_phys_addr(). This new HAL provides the real phys
address that should be passed to the GPU from a physical address
obtained from a scatter list. It also provides a mechanism by
which the HAL code can add extra bits to a GPU physical address
based on the attributes passed in. This is necessary during GMMU
page table programming.
Also remove the flags argument from the various address functions.
This flag was used for adding an IO coherence bit to the GPU
physical address which is not supported.
