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.

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.

PG419 board had been reworked to swap I2C_B and I2C_C
(in order to solve PL issues). As a result, on this
board we now use a different I2C port than on PG418.
Remove support for non-reworked boards: VBIOS version
must be at least .56
Add I2C port in platform data.

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.

Add a function to create a nvgpu_mem from a list of arbitrary pages.
This API is useful for pages not necessarily allocated by the Linux
page allocator. It is useful for making nvgpu_mems that represent
carveouts or other things like that.

Add an API for creating a special sub-nvgpu_mem struct. This struct
comes with some fairly important caveats but is very useful for the
semaphore code.
Also, make sure that in nvgpu_mem_begin() and nvgpu_mem_end() no
additional mappings are made if not necessary. More importantly during
nvgpu_mem_end() it would be possible to vunmap() a CPU mapping of a
DMA allocation that does not expect this to happen.

includes some functions in allocators that were used only for
debugging.
Remove include of linux/debugfs.h on files that do not deal with

linux/debugfs.h implicitly included linux/fs.h, which we relied on.
Add explicit include of linux/fs.h for all files where this is the
case.

Hide the Linux specific nvgpu_mem fields so that in subsequent patches
core code can instead of using struct sg_table it can use mem_desc.
Routines for accessing system specific fields will be added as needed.
This is the first step in a fairly major overhaul of the GMMU mapping
routines. There are numerous issues with the current design (or lack
there of): massively coupled code, system dependencies, disorganization,
etc.
