Add support for clearing single SM error state for CUDA debugger.
In addition to clearing local copy of SM error state,
vgpu_gr_clear_sm_error_state now sends a command to RM server
(TEGRA_VGPU_CMD_CLEAR_SM_ERROR_STATE), to clear global ESR and
warp ESR.

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

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

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.

With NVGPU_IOCTL_CHANNEL_EVENTS_CTRL, nvgpu can
raise events to User space. But user space
cannot distinguish between various types of events.
To overcome this, we need finer-grained API to
deliver various events to user space.
Remove old API NVGPU_IOCTL_CHANNEL_EVENTS_CTRL,
and all the support for this API (we can remove
this since User space has not started using this
API at all)
Add new API NVGPU_IOCTL_CHANNEL_EVENT_ID_CTRL
which will accept an event_id (like BPT.INT or
BPT.PAUSE), a command to enable the event,
and return a file descriptor on which
we can raise the event (if cmd=enable)
Event is disabled when file descriptor is closed
Add file operations "gk20a_event_id_ops"
to support polling on event fd
Also add API gk20a_channel_get_event_data_from_id()
to get event_data of event from its id

Restore comptags to be bitmap-allocated, like they were before we had
the buddy allocator.
The new buddy allocator introduced by
e99aa2485f8992eabe3556f3ebcb57bdc8ad91ff (originally
6ab2e0c49cb79ca68d2f83f1d4610783d2eaa79b) is fine for the big VAs, but
unsuitable for the small compbit store.
This commit reverts partially the combination of the above commit and
also one after it, 86fc7ec9a05999bea8de320840b962db3ee11410, that fixed
a bug which is not present when using a bitmap. With a bitmap allocator,
pruning the extra allocation necessary for user-mapped mode is possible,
so that is also restored.
The original generic bitmap allocator is not restored; instead, a
comptag-only allocator is introduced.
