Move the platform_gk20a.h include out of the ifdef CONFIG_DEBUG_FS
in the CDE code since dev_from_gk20a() is used regardless of
whether debugfs is enabled.
Also modify some of the CE ops to take a struct gk20a instead of a
struct device. This avoids any requirement for including
linux/device.h or platform_gk20a.h.

nvgpu_log/info/warn/err() internally add a \n to the end of the message.
Hence, callers should not include a \n at the end of the message. Doing
so results in duplicate \n being printed, which ends up creating empty
log messages. Remove the duplicate \n from all err/warn messages.

Split handling of stalling interrupt to Linux specific chip
agnostic and OS independent chip specific parts.
Linux specific chip independent part contains handler for ISR
and passing the control to a bottom half. It uses the new MC HALs
intr_stall (query interrupt status), intr_pause (pause interrupts)
and intr_resume (resume interrupts).
MC HAL isr_stall now returns void and gets called in thread context
and thus remove isr_thread_stall and replace the implementation with
isr_stall.

Remove the VM init/de-init from the HAL and instead use a single
set of routines that init/de-init VMs. This prevents code divergence
between vGPUs and regular GPUs.
This patch also clears up the naming of the routines a little bit.
Since some VMs are used inplace and others are dynamically allocated
the APIs for freeing them were confusing. Also some free calls also
clean up an instance block (this is API abuse - but this is how it
currently exists).
The new API looks like this:
void __nvgpu_vm_remove(struct vm_gk20a *vm);
void nvgpu_vm_remove(struct vm_gk20a *vm);
void nvgpu_vm_remove_inst(struct vm_gk20a *vm,
struct nvgpu_mem *inst_block);
void nvgpu_vm_remove_vgpu(struct vm_gk20a *vm);
int nvgpu_init_vm(struct mm_gk20a *mm,
struct vm_gk20a *vm,
u32 big_page_size,
u64 low_hole,
u64 kernel_reserved,
u64 aperture_size,
bool big_pages,
bool userspace_managed,
char *name);
void nvgpu_deinit_vm(struct vm_gk20a *vm);

This also involved moving a bunch of GMMU code out into the

In gr_gk20a_handle_sm_exception(), we disable all SM exceptions
if SM debug mode is set and irrespective of exception type
But we should not disable SM exceptions if the only
exception is BPT_INT
Fix this by checking if only interrupt is BPT_INT and
do not disable SM exceptions in that case
Note that for rest of the exceptions we still need to
disable SM exceptions
Also, remove redudant checks of sm_debugger_attached since
we bail out early if this flag is not set anyways

This function is an internal function to the VM manager that allocates
virtual memory space in the GVA allocator. It is unfortunately used in
the vGPU code, though. In any event, this patch cleans up and moves the
implementation of these functions into the VM common code.

The timeout parameter to NVGPU_COND_WAIT()
was passed directly to wait_event_timeout(), which takes jiffies.
Also allows zero timeout to disable timeout.
The return value of NVGPU_COND_WAIT() was defined in a way specific
to how Linux wait_event_() calls work. Replace that with proper error
reporting and change the callers to check against error codes.

The vm_reserve_va_node struct is essentially a special VM area that
can be used for sparse mappings and fixed mappings. The name of this
struct is somewhat confusing (as node is typically used for list
items). Though this struct is a part of a list it doesn't really
make sense to call this a list item since it's much more. Based on
that the struct has been renamed to nvgpu_vm_area to capture the
actual use of the struct more accurately.
This also moves all of the management code of vm areas to a new file
devoted solely to vm_area management.
Also add a brief overview of the VM architecture. This should help
other people follow along the hierachy of ownership and lifetimes in
the rather complex MM code.

This patch begins splitting out the VM implementation from mm_gk20a.c and
moves it to common/linux/vm.c and common/mm/vm.c. This split is necessary
because the VM code has two portions: first, an interface for the OS
specific code to use (i.e userspace mappings), and second, a set of APIs
for the driver to use (init, cleanup, etc) which are not OS specific.
This is only the beginning of the split - there's still a lot of things
that need to be carefully moved around.

This patch begins the major rework of the GPU's virtual memory manager
(VMM). The VMM is the piece of code that handles the userspace interface
to buffers and their mappings into the GMMU. The core data structure is
the VM - for now still known as 'struct vm_gk20a'. Each one of these
structs represents one addres space to which channels or TSGs may bind
themselves to.
The VMM splits the interface up into two broad categories. First there's
the common, OS independent interfaces; and second there's the OS specific
interfaces.
OS independent
--------------
This is the code that manages the lifetime of VMs, the buffers inside
VMs (search, batch mapping) creation, destruction, etc.
OS Specific
-----------
This handles mapping of buffers represented as they are represented by
the OS (dma_buf's for example on Linux).
This patch is by no means complete. There's still Linux specific functions
scattered in ostensibly OS independent code. This is the first step. A
patch that rewrites everything in one go would simply be too big to
effectively review.
Instead the goal of this change is to simply separate out the basic
OS specific and OS agnostic interfaces into their own header files. The
next series of patches will start to pull the relevant implementations
into OS specific C files and common C files.
