uart is littered with gk20a_channel_poll_timeouts prints if nvgpu_dbg_mask
has gpu_dbg_fn bit set. This function is looping every living kernel
so removing this print in order to not keep uart busy printing it.

Use platform agnostic delay functions instead of Linux kernel APIs.
This allows removing dependency to Linux header linux/delay.h. At the
same time remove #include lines for other unused Linux headers.

Move code that touches host registers and instance block to fifo HAL.
This involves adding HAL ops for the fifo HAL functions that get
called from outside fifo. This clears responsibility of channel by
leaving it only managing channels in software and push buffers.
channel had member ramfc defined, but it was not used, to remove it.
pbdma_acquire_val consisted both of channel logic and hardware
programming. The channel logic was moved to the caller and only
hardware programming was moved.

The nvgpu timer API prints a message when the timer expires, but
expiration of that does not necessarily mean here that the job has
actually timed out, which is tested by comparing gp_get. Change the
expiration check to just peek instead of the default which prints to
log on expiration.

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

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.

Implement a worker thread to replace the delayed works in channel
watchdog and job cleanups. Watchdog runs by polling the channel states
periodically, and job cleanup is performed on channels that are appended
on a work queue consumed by the worker thread. Handling both of these
two in the same thread makes it impossible for them to cause a deadlock,
as has previously happened.
The watchdog takes references to channels during checking and possibly
recovering channels. Jobs in the cleanup queue have an additional
reference taken which is released after the channel is processed. The
worker is woken up from periodic sleep when channels are added to the
queue.
Currently, the queue is only used for job cleanups, but it is extendable
for other per-channel works too. The worker can also process other
periodic actions dependent on channels.
Neither the semantics of timeout handling or of job cleanups are yet
significantly changed - this patch only serializes them into one
background thread.
Each job that needs cleanup is tracked and holds a reference to its
channel and a power reference, and timeouts can only be processed on
channels that are tracked, so the thread will always be idle if the
system is going to be suspended, so there is currently no need to
explicitly suspend or stop it.

mutex_is_locked() API is defined on Linux only
and not on other OS like QNX.
Hence remove use of this API for OS abstraction
support to nvgpu.
Instead of using mutex_is_locked(), use
mutex_trylock() for same purpose

This ioctl can be used on gp10b to set a flag in the context header
indicating this context should be run at elevated clock
frequency. FECS ctxsw ucode will read this flag as part of the context
switch and will request higher GPU clock frequencies from BPMP for the
duration of the context execution.

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.

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.

Instead of checking if a job is complete, only check that channel is
making progress by checking its gp_get is advancing.
This will make the watchdog conservative. Previously a whole job had
x seconds to complete. Now channel has x seconds to get host to
consume each push buffer segment.

Use the timers API in the gk20a code instead of Linux specific
API calls.
This also changes the behavior of several functions to wait for
the full timeout for each operation that can timeout. Previously
the timeout was shared across each operation.

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.

Dump the most recent actions to syslog when
gk20a_wait_until_counter_is_N gets stuck when closing a channel.
GK20A_CHANNEL_REFCOUNT_TRACKING specifies the size of the action

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().

In gk20a_submit_prepare_syncs(), after we have allocated wait_cmd
we check the results. If we failed to allocate wait_cmd, we still
jump to the error label that tries to free wait_cmd.
Create an own error labal for allocation before wait_cmd, and use
that if we fail to allocate wait_cmd.
Similarly create an error label for incr_cmd, and use that only once
incr_cmd has actually been allocated.
