Instead of using a single static kmem_cache for each type of
data structure the allocators may want to allocate each
allocator now has its own instance of the kmem_cache. This is
done so that each GPU driver instance can accurately track how
much memory it is using.
In order to support this on older kernels a new NVGPU API has
been made,
nvgpu_kmem_cache_create(struct gk20a *g, size_t size)
To handle the possibility that caches cannot be created with
the same name.
This patch also fixes numerous places where kfree() was wrongly
used to free kmem_cache allocs.

Simplify ref-counting on VMs: take a ref when a VM is bound to a
channel and drop a ref when a channel is freed.
Previously ref-counts were scattered over the driver. Also the CE
and CDE code would bind channels with custom rolled code. This was
because the gk20a_vm_bind_channel() function took an as_share as
the VM argument (the VM was then inferred from that as_share).
However, it is trivial to abtract that bit out and allow a central
bind channel function that just takes a VM and a channel.

Remove the special VMA that could be used for allocating fixed
addresses. This feature was never used and is not worth maintaining.

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.

Make sure that map_offset is set to the fixed map address or 0)
before determining PTE size. Then use map_offset instead of
offset_align for computing the PTE size since offset_align
could be either an alignment ora fixed mapping offset.
Also is the minimum of the buffer size and the buffer alignment
for computing page size. This is necessary is the GMMU is doing
page gathering (i.e the buffer does not appear as a continguous
IOMMU range to the GPU). Is such cases a large page sized buffer
may be made up of a bunch of discontiguous 4k pages.

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.

We did not follow the proper sequence to reset priv ring on error.
Instead we just re-enabled priv ring, which does not reset anything.
Rename the gk20a_reset_priv_ring() to gk20a_enable_priv_ring() to
indicate its proper use. Add another gk20a_reset_priv_ring() which
actually resets priv ring properly.

During testing it was detected that a failure in loading the firmware
for the driver would not propagate, allowing some function pointers to
be left unitialized. This would cause a kernel-crash later on.
