 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.
