Use nvgpu rbtree instead of linux rbtree to store
mapped buffers for each VM
Move to use "struct nvgpu_rbtree_node" instead of
"struct rb_node"
And similarly use rbtree APIs from <nvgpu/rbtree.h>
instead of linux APIs

Replace the last of the Linux kmem API usage with nvgpu kmem
calls instead. Several places are left alone - allocating the
struct gk20a in particular.
Also one function was updated in the clk code to take a struct
gk20a as an argument so that it could use nvgpu_kmalloc().

Commit 8f3875393e7a6bd0fc03afdb1fa99b7e33b71576 ("abstract away dma
alloc attrs") added an implicit NVGPU_DMA_NO_KERNEL_MAPPING for the
explicit vidmem buffer allocation path. The default allocation api that
chooses vidmem or sysmem based on available support still passed a zero
flag and produced a warning when the flag should have been there. Force
the NO_KERNEL_MAPPING flag on currently via the default-allocator api.
Commit 8a15e02ca92b83aa5a216ea9cd42680373212ecd ("gpu: nvgpu: add
NO_KERNEL_MAPPING for alloc_map_vid") did the same for flagless
alloc-and-map calls but this default alloc-only call got overlooked.
Also, store the flags in the mem_desc during allocation, just like in
the sysmem allocator, to be checked during freeing.

There were still a few remaining loops where we did not use
nvgpu_timeout and required Tegra specific functions for detecting if
timeout should be skipped. Replace all of them with nvgpu_timeout and
remove including chip-id.h where possible.
FE power mode timeout loop also used wrong delay value. It always
waited for the whole max timeout instead of looping with smaller
increments.
If SEC2 ACR boot fails to halt, we should not try to check ACR result
from mailbox. Add an early return for that case.

This change refactors the teardown in remove to ensure that it is
possible to unload the driver while leaving fds open. This is achieved
by making sure that the SW state is kept alive till all fds are closed
and by checking that subsequent calls to ioctls after the teardown fail.
Normally, this would be achieved ny calls into gk20a_busy(), but in
kickoff we dont call into that to reduce latency, so we need to check
the driver status directly, and also in some of the functions
as we need to make sure the ioctl does not dereference the device or
platform struct

Don't use enum dma_attr in the gk20a_gmmu_alloc_attr* functions, but
define nvgpu-internal flags for no kernel mapping, force contiguous, and
read only modes. Store the flags in the allocated struct mem_desc and
only use gk20a_gmmu_free, remove gk20a_gmmu_free_attr. This helps in OS
abstraction. Rename the notion of attr to flags.
Add implicit NVGPU_DMA_NO_KERNEL_MAPPING to all vidmem buffers
allocated via gk20a_gmmu_alloc_vid for consistency.
Fix a bug in gk20a_gmmu_alloc_map_attr that dropped the attr
parameter accidentally.

of FB hardware headers from other files.
TLB invalidate function took previously a pointer to VM, but the new
API takes only a PDB mem_desc, because FB does not need to know about
higher level VM.
GPC MMU is programmed from the same function as FB MMU, so added
dependency to GR hardware header to FB.
GP106 ACR was also triggering a VPR fetch, but that's not applicable

Change nvgpu_kalloc() to nvgpu_big_[mz]alloc(). This is necessary
since the natural free function name for this is nvgpu_kfree() but
that conflicts with nvgpu_k[mz]alloc() (implemented in a subsequent
patch).
This API exists becasue not all allocation sizes can be determined
at compile time and in some cases sizes may vary across the system
page size. Thus always using kmalloc() could lead to OOM errors due
to fragmentation. But always using vmalloc() is wastful of memory
for small allocations. This API tries to alleviate those problems.

In gk20a_vm_map_duplicate_locked(), we always do a linear search
in rb-tree to find a duplicate entry of the buffer
In case NVGPU_AS_MAP_BUFFER_FLAGS_FIXED_OFFSET is set, we first
traverse whole rb-tree linearly and then compare offset_align
with the address searched from rb-tree
If size of rb-tree is very large this linear lookup takes upto
7mS and causes huge delays
Hence in case of NVGPU_AS_MAP_BUFFER_FLAGS_FIXED_OFFSET, we can
use offset_align to perform a binary search on rb-tree and then
verify that dmabuf and kind match with the node obtained from
the search
This saves a lot of time per-lookup

Move semaphore_gk20a.c drivers/gpu/nvgpu/common/ since the semaphore

Move the semaphore_gk20a.h header file to drivers/gpu/nvgpu/include/nvgpu
and rename it to semaphore.h. Also update all places where the header
is inluced to use the new path.
This revealed an odd location for the enum gk20a_mem_rw_flag. This should
be in the mm headers. As a result many places that did not need anything
semaphore related had to include the semaphore header file. Fixing this
oddity allowed the semaphore include to be removed from many C files that
did not need it.

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.

VA spaces. This is useful for the dGPU where having a unified
address space has no problems. On iGPUs testing issues is
getting in the way of enabling this feature.

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.

and make the driver more readable and scalable.

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().
