drm/ttm: Fix race condition in ttm_bo_delayed_delete (v3, final)
Resending this with Thomas Hellstrom's signoff for merging into 2.6.33
ttm_bo_delayed_delete has a race condition, because after we do:
kref_put(&nentry->list_kref, ttm_bo_release_list);
we are not holding the list lock and not holding any reference to
objects, and thus every bo in the list can be removed and freed at
this point.
However, we then use the next pointer we stored, which is not guaranteed
to be valid.
This was apparently the cause of some Nouveau oopses I experienced.
This patch rewrites the function so that it keeps the reference to nentry
until nentry itself is freed and we already got a reference to nentry->next.
v2 updated by me according to Thomas Hellstrom's feedback.
v3 proposed by Thomas Hellstrom. Commit comment updated by me.
Both updates fixed minor efficiency/style issues only and all three versions
should be correct.

drm/nouveau: check pushbuffer bounds in ioctl
Currently there is no check that the pushbuffer request bounds are inside
the TTM BO.
This allows to instruct the kernel to do relocations on user-selected
addresses, since the relocation bounds checking relies on the request
bounds.
This can oops the kernel accidentally and is easily exploitable.
This patch adds bound checking and alignment checking for ->offset and
->nr_dwords.
It also makes some variables unsigned, which should have no effect,
but prevents possible bounds checking problems.

Apparently the original reason for checking this was there were known

than likely because of incorrect parsing of previous opcodes, and I
hardly think aborting a script half way through is going to be any
better (in fact, we have had bug reports where this has been the cause
of s/r failures among other things).
This patch (which has been in Fedora 12 for a long time now) removes
all checking for known register ranges, and just leaves the check to
ensure the access is within the mapped aperture to avoid an oops.

The below is mainly an educated guess at what's going on, docs would
sure be handy... NVIDIA? :P
It appears it's possible for a ctxprog to run even while a GPU exception
is pending. The GF8 and up ctxprogs appear to have a small snippet of
code which detects this, and stalls the ctxprog until it's been handled,
which essentially looks like:
if (r2 & 0x00008000) {
r0 |= 0x80000000;
while (r0 & 0x80000000) {}
}
I don't know of any way that flag would get cleared unless the driver
intervenes (and indeed, in the cases I've seen the hang, nothing steps
in to automagically clear it for us). This patch causes the driver to
clear the flag during the PGRAPH IRQ handler.

drm/nouveau: Fix null deref in nouveau_fence_emit due to deleted fence
Currently Nouveau will unvalidate all buffers if it is forced to wait on
one, and then start revalidating from the beginning. While doing so, it
destroys the operation fence, causing nouveau_fence_emit to crash.
This patch fixes this bug by taking the fence object out of validate_op
and creating it just before emit. The fence pointer is initialized to 0
and unref'ed unconditionally.
In addition to fixing the bug, this prevents its reintroduction and
simplifies the code.

drm/nv50: prevent a possible ctxprog hang
The below is mainly an educated guess at what's going on, docs would
sure be handy... NVIDIA? :P
It appears it's possible for a ctxprog to run even while a GPU exception
is pending. The GF8 and up ctxprogs appear to have a small snippet of
code which detects this, and stalls the ctxprog until it's been handled,
which essentially looks like:
if (r2 & 0x00008000) {
r0 |= 0x80000000;
while (r0 & 0x80000000) {}
}
I don't know of any way that flag would get cleared unless the driver
intervenes (and indeed, in the cases I've seen the hang, nothing steps
in to automagically clear it for us). This patch causes the driver to
clear the flag during the PGRAPH IRQ handler.
