Add an accessor function in the priv cmdbuf object for gva and size to
be written in a gpfifo entry once the cmdbuf build is finished. This
helps in eventually hiding the struct priv_cmd_entry as an
implementation detail.
Add a sanity check to verify that the buffer has been filled exactly to
the requested size. The cmdbufs are used to hold wait and increment
commands for syncpoints or gpu semaphores. A prefence buffer can hold a
number of wait commands of equal size, and the postfence buffer holds
exactly one increment.

Add an API to append data to a priv cmdbuf entry. Hold the write pointer
offset internally in the entry instead of having the user keep track of
where those words are written to.
This helps in eventually hiding struct priv_cmd_entry from users and
provides a more consistent interface in general. The wait and incr
commands are now slightly easier to read as well when they're just
arrays of data.
A syncfd-backed prefence may be composed of several individual fences.
Some of those (or even a fence backed by just one) may be already
expired, and currently the syncfd export design releases and nulls
semaphores when expired (see gk20a_sync_pt_has_signaled()) so for those
the wait cmdbuf is appended with zeros; the specific function is for
this purpose.

Instead of one HAL op with a boolean flag to decide whether to do one
thing or another entirely different thing, use two separate HAL ops for
filling priv cmd bufs with semaphore wait and semaphore increment
commands. It's already two ops for syncpoints, and explicit commands are
more readable than boolean flags.
Change offset into cmdbuf in sem wait HAL to be relative to the cmdbuf,
so the HAL adds the cmdbuf internal offset to it.
While at it, modify the syncpoint cmdbuf HAL ops' prototypes to be
consistent.

Move struct priv_cmd_queue to priv_cmdbuf.c so that its definition does
not need to be visible to all users of channel.h. This also forces it to
be separately allocated (during channel init time).
While at it, rename the functions to allocate and free priv cmdbuf
queues now that they're not in channel.c anymore. A private command
buffer queue is a piece of dma memory from which entries for incr and
wait command lists are suballocated. As the name implies, it's a queue;
allocations and frees of the bufs must happen in certain order.

Linux's mm.h defines at least PAGE_ALIGN which nvgpu uses and provides
via utils.h. It's defined internally in posix/utils.h, but in Linux the
OS version is relied upon. However, the macro definition has spilled in
via the trace events that includes linux/ktime.h. If nvgpu/trace.h isn't
included, we wouldn't get that.

Refactor user managed syncpoints out of the channel sync infrastructure
that deals with jobs submitted via the kernel api. The user syncpt only
needs to expose the id and gpu address of the reserved syncpoint. None
of the rest (fences, priv cmdbufs) is needed for that, so it hasn't been
ideal to couple with the user-allocated syncpts.
With user syncpts now provided by channel_user_syncpt, remove the
user_managed flag from the kernel sync api.
This allows moving all the kernel submit sync code to be conditionally
compiled in only when needed, and separates the user sync functionality
in a more clear way from the rest with a minimal API.
[this is squashed with commit 5111caea601a (gpu: nvgpu: guard user
syncpt with nvhost config) from
