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().

ctrl_gk20a.c had some direct accesses to hardware. These violate the
HAL rules, because we don't have per-GPU ctrl, and thus the code
cannot be made GPU independent.
Move all GR accesses to new GR HALs and use existing bus HAL for
accessing timer. Remove #includes of all hardware headers.

Move the name field from struct gpu_ops up to struct gk20a. The field
is not a function op, so it doesn't belong in gpu_ops.
Replace all uses of dev_name() with use of g->name when possible.

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.

Clean up gk20a.c by removing direct accesses to MC and moving the
accesses to happen via MC HAL.
The chip detection logic has to violate the HAL and call gk20a
version directly, because HAL ops cannot be set up before chip has
been identified.

Currently NVGPU_CHANNEL_FIFO_ERROR_MMU_ERR_FLT is being set in
error notifier for non mmu fault too. For fake mmu faults i.e.
trigger mmu fault cases, make sure proper notifiers are set and
driver is not depending on sending mmu error fault notifier.
This change is needed for t19x fifo recovery too.
NVGPU_CHANNEL_GR_ERROR_SW_METHOD (12), NVGPU_CHANNEL_GR_EXCEPTION(13)
and NVGPU_CHANNEL_FECS_ERR_UNIMP_FIRMWARE_METHOD (37) are new error
notifiers.

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.

Move all programming of FB to fb_*.c files, and remove the inclusion
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
to dGPU, so removed that call.

In gk20a_suspend_all_sms(), we currently loop
over all GPCs and then loop over all TPCs in inner
loop
But this is incorrect and leads to SM with
invalid GPC,TPC ids
Fix this by looping over number of TPCs in each
GPC in inner loop
Also, fix gk20a_gr_wait_for_sm_lock_down() as
per below
- we right now wait infinitely for SM to lock down
- restrict this wait with a timeout on silicon
platforms
- return ETIMEDOUT instead of EAGAIN
- add more debug prints with additional data
for SM lock down failures

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.

Move semaphore_gk20a.c drivers/gpu/nvgpu/common/ since the semaphore
code is common to all chips.
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.

When gpu host is executing a context, there should not be any calls
to fecs that can change the current context in execution. For some
reason legacy fmodels are calling fecs method to golden
context restore while loading golden context for new channel.
This call is not required and should not be called. Only first
time during golden context creation, fecs methods like bind can be
called and it is pretty safe to do.

When kernel adds patches to a context, kernel needs to update
the patch count in order for FECS to pick up the new patches.
Previously patching was done only at the context creation
time. Now patching is used also when changing preemption mode,
but the patches did not take effect due to not updating count.
Update patch count every time we end patching of a context.

Reorganize the HW headers of gk20a. The headers are moved to a
new directory:
include/nvgpu/hw/gk20a
And from the code are included like so:
#include <nvgpu/hw/gk20a/hw_pwr_gk20a.h>
This is the first step in reorganizing all of the HW headers for
gm20b, gm206, etc. This is part of a larger effort to re-structure
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().

gm20b_init_gr does not inherit the ops set by gk20a_init_gr_ops, and the
gr.setup_rop_mapping HAL was not set there, so it was not set for chips
that inherit from gm20b_init_gr and do not override it explicitly.
Set the pointer in gm20b_init_gr, which other chips inherit, and delete
the surrounding if condition from the call, making sure that future
users always call it, because there is an implementation since the
earliest supported chip.

In calls to gk20a_fifo_recover() we pass a bitfield of engines to
recover. We generate the bitfield by acquiring engine id from FIFO,
and using BIT(). If GR engine is now known, the resulting engine ID is
u32 with all bits set, which cannot be passed to BIT().
gk20a_fifo_recover() can already deal with all bits set, so pass that
verbatim instead.
