8522004c00 gpu: nvgpu: Falcon-controller interface update
Moved falcon-controller common interface code
from pmu_common.h to flcnif_cmn.h file.
Interfaces are common for falcons irrespective
of F/W on falcon controllers

d630f1d99f gpu: nvgpu: Unify the small and large page address spaces
The basic structure of this patch is to make the small page allocator
and the large page allocator into pointers (where they used to be just
structs). Then assign each of those pointers to the same actual
allocator since the buddy allocator has supported mixed page sizes
since its inception.

For the rest of the driver some changes had to be made in order to
actually support mixed pages in a single address space.

1. Unifying the allocation page size determination

   Since the allocation and map operations happen at distinct
   times both mapping and allocation of GVA space must agree
   on page size. This is because the allocation has to separate
   allocations into separate PDEs to avoid the necessity of
   supporting mixed PDEs.

   To this end a function __get_pte_size() was introduced which
   is used both by the balloc code and the core GPU MM code. It
   determines page size based only on the length of the mapping/
   allocation.

2. Fixed address allocation + page size

   Similar to regular mappings/GVA allocations fixed address
   mapping page size determination had to be modified. In the
   past the address of the mapping determined page size since
   the address space split was by address (low addresses were
   small pages, high addresses large pages). Since that is no
   longer the case the page size field in the reserve memory
   ioctl is now honored by the mapping code. When, for instance,
   CUDA makes a memory reservation it specifies small or large
   pages. When CUDA requests mappings to be made within that
   address range the page size is then looked up in the reserved
   memory struct.

   Fixed address reservations were also modified to now always
   allocate at a PDE granularity (64M or 128M depending on
   large page size. This prevents non-fixed allocations from
   ending up in the same PDE and causing kernel panics or GMMU
   faults.

3. The rest...

   The rest of the changes are just by products of the above.
   Lots of places required minor updates to use a pointer to
   the GVA allocator struct instead of the struct itself.

Lastly, this change is not truly complete. More work remains to be
done in order to fully remove the notion that there was such a thing
as separate address spaces for different page sizes. Basically after
this patch what remains is cleanup and proper documentation.

dddeee54b6 gpu: nvgpu: Fix priv ring error detection
Use hardware headers instead of hardcoded register numbers in priv
ring. This required updating the priv ring headers to add all the
registers and fields needed.

Incidentally this also gets rid of a lot of GPC priv ring registers
as they're not used in our code.

Also delete duplicate prints for the same information. We were
dumping GPC error also in gk20a_pbus_isr(), and we dumped master
information twice.

Dump status of each GPC separately instead of supporting only GPC0.

a86122e01a gpu: nvgpu: read overcurrent policy from VBIOS
Since pwr_sensors, pwr_topology_ and pwr_policy_* tables in bios.h
are not defined as packed, nvgpu driver is not able to find hw
threshold pwr_policy table in VBIOS and ends up hard coding the HW
thershold policy.
Changed definitions to packed, and explicitly unpack structures
when parsing the power policy table. Removed the function that
did the hard coding.

Move the GPU allocators to common/mm/ since the allocators are common
code across all GPUs. Also rename the allocator code to move away from
gk20a_ prefixed structs and functions.

This caused one issue with the nvgpu_alloc() and nvgpu_free() functions.
There was a function for allocating either with kmalloc() or vmalloc()
depending on the size of the allocation. Those have now been renamed to
nvgpu_kalloc() and nvgpu_kfree().
