-Handle pbus and priv stall interrupts first.
In general critical interrupts should be
handled before any other non critical ones.

trace_printk() does an extra stringify operation before calling
do_trace_printk(). The string ends up unused. This has an impact
to kernel even if we never end up using trace_printk().
Disable use of trace_printk() and introduce a Kconfig option for
re-enabling it.

make the code use the real defines. No longer is hiding t18x specific

Instead of using Linux APIs for mutex and spinlocks
directly, use new APIs defined in <nvgpu/lock.h>
Replace Linux specific mutex/spinlock declaration,
init, lock, unlock APIs with new APIs
e.g
struct mutex is replaced by struct nvgpu_mutex and
mutex_lock() is replaced by nvgpu_mutex_acquire()
And also include <nvgpu/lock.h> instead of including
<linux/mutex.h> and <linux/spinlock.h>
Add explicit nvgpu/lock.h includes to below
files to fix complilation failures.

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.

Remove including gk20a.h from pmu_gk20a.h. This causes a fallout
as some #includes were missing.
gr_gp10b.h uses mem_desc, but did not include mm_gk20a.h. Add the
include.
Including mm_gk20a.h in gr_gp10b.h causes recursive include, as
mm_gk20a.h has some gr defines. Move the defines to gr_gk20a.h to
remove the dependency.
gr_ctx_gk20a.h used struct gk20a pointers, but did not forward
declare it. Add a forward declaration.
gr_gk20a.h uses dbg_session_gk20a, but was missing forward
declaration.
gr_gk20a.h did not include nvgpu.h but it uses preemption types from
that header. Add include.

We right now get min and max frequencies, and then
interpolate rest of the frequencies.
With this approach, we do not select exact
frequencies as supported by h/w
Fix this so that we query all supported frequencies
using clk_round_rate() and then select every N'th
frequency to keep number of frequencies under limit
Use GP10B_FREQ_SELECT_STEP (currently set to 8)
to configure frequency selection step
Raise GP10B_MAX_SUPPORTED_FREQS to 200 since h/w
supported frequencies could be in that range

We can trigger CILP only if SM debug mode is on.
So in fecs interrupt handler, we could have graphics context
running for which SM debug mode is disabled.
And in that case we skip posting of cilp completion
events to UMD.
But since CILP event was anyways triggered, we need to post
events to UMD irrespective of SM debug mode is enabled
at that point or not
Hence remove check gk20a_gr_sm_debugger_attached() for
posting events to UMD

In gp10b_ce_nonstall_isr(), we trigger a semaphore wakeup.
Currently, we clear the interrupt status register after the
wakeup is complete. There is potential for an interrupt to
come in while the wake-up operation is in progress, and it
is possible that:
1) We miss processing the interrupt in that ISR iteration AND
2) We clear the interrupt status register anyways
This change clears the status register before triggering wakeup,
so the interrupt will properly re-fire.

GPU frequencies can be set by powerhal when GPU is railgated,
and before this change that would cause EMC floors to remain
set until GPU is unrailgated.
After this change, EMC floors are not requested by the GPU
client when the GPU is railgated. It is ok to ignore the
requests, as the GPU client maxes the floor when powering
up.
