drm/amdgpu: Fix for drm buddy memory corruption
User reported gpu page fault when running graphics applications
and in some cases garbaged graphics are observed as soon as X
starts. This patch fixes all the issues.
Fixed the typecast issue for fpfn and lpfn variables, thus
preventing the overflow problem which resolves the memory
corruption.

drm/nouveau: Don't pm_runtime_put_sync(), only pm_runtime_put_autosuspend()
While trying to fix another issue, it occurred to me that I don't actually
think there is any situation where we want pm_runtime_put() in nouveau to
be synchronous. In fact, this kind of just seems like it would cause
issues where we may unexpectedly block a thread we don't expect to be
blocked.
So, let's only use pm_runtime_put_autosuspend().
Changes since v1:
* Use pm_runtime_put_autosuspend(), not pm_runtime_put()

drm/nouveau/kms: Fix failure path for creating DP connectors
It looks like that when we moved nouveau over to using drm_dp_aux_init()
and registering it's aux bus during late connector registration, we totally
forgot to fix the failure codepath in nouveau_connector_create() - as it
still seems to assume that drm_dp_aux_init() can fail (it can't).

ida: don't use BUG_ON() for debugging
This is another old BUG_ON() that just shouldn't exist (see also commit
a382f8fee42c: "signal handling: don't use BUG_ON() for debugging").
In fact, as Matthew Wilcox points out, this condition shouldn't really
even result in a warning, since a negative id allocation result is just
a normal allocation failure:
"I wonder if we should even warn here -- sure, the caller is trying to
free something that wasn't allocated, but we don't warn for
kfree(NULL)"
and goes on to point out how that current error check is only causing
people to unnecessarily do their own index range checking before freeing
it.
This was noted by Itay Iellin, because the bluetooth HCI socket cookie
code does *not* do that range checking, and ends up just freeing the
error case too, triggering the BUG_ON().
The HCI code requires CAP_NET_RAW, and seems to just result in an ugly
splat, but there really is no reason to BUG_ON() here, and we have
generally striven for allocation models where it's always ok to just do
free(alloc());
even if the allocation were to fail for some random reason (usually
obviously that "random" reason being some resource limit).

gpu: host1x: Register context bus unconditionally
Conditional registration is a problem for other subsystems which may
unwittingly try to interact with host1x_context_device_bus_type in an
uninitialised state on non-Tegra platforms. A look under /sys/bus on a
typical system already reveals plenty of entries from enabled but
otherwise irrelevant configs, so lets keep things simple and register
our context bus unconditionally too.

signal handling: don't use BUG_ON() for debugging
These are indeed "should not happen" situations, but it turns out recent
changes made the 'task_is_stopped_or_trace()' case trigger (fix for that
exists, is pending more testing), and the BUG_ON() makes it
unnecessarily hard to actually debug for no good reason.
It's been that way for a long time, but let's make it clear: BUG_ON() is
not good for debugging, and should never be used in situations where you
could just say "this shouldn't happen, but we can continue".
Use WARN_ON_ONCE() instead to make sure it gets logged, and then just
continue running. Instead of making the system basically unusuable
because you crashed the machine while potentially holding some very core
locks (eg this function is commonly called while holding 'tasklist_lock'
