Set nouveau to a more reasonable debug level.
Match the compile-time and default run-time settings in Linux.
--
Pass a sensible device state pointer to nouveau suspend/resume ops.
Gives nouveau half a chance of suspending and resuming -- not that it
works on my test laptop yet, but it's a start.
--
Fix bus_space_subregion error branch.
Return error code, not 0 (!), on bus_space_subregion failure.
In answer to `XXX error branch' comment: if nouveau_barobj_ctor
fails, then the caller will call nouveau_barobj_dtor too.  So there's
no leak here.
Unlikely to fix any observed bugs with nouveau -- there's no error
branch in the Linux side here.  But maybe it will catch some other
bug earlier.
--
Map the same mmio size as Linux does.
Unlikely to have practical consequences -- just reduces differences
in behaviour from upstream, to rule them out.
--
Print error code for failure to map PRAMIN BAR.
--
In msleep use mdelay if cold
--
Use only the low 32 bits of the bar object's vma offset as intended.
Should fix PR kern/50372, seen by everyone trying to use nouveau on
amd64 with hardware that uses nv50-style BARs and not nvc0-style
BARs.
--
Destroy the lock before caller frees memory.
--
Destroy spin locks appropriately.
--
Destroy the mutex before free.
--
Provide reader/writer semantics with recursive readers.
--
Exclude VRAM and FIFO regions from MMIO register mapping.
Nouveau maps those separately, and it is not trivial to convert those
mappings to bus_space_subregion.
