Fix unaligned accesses for SPARC
The nouveau driver makes a number of unaligned accesses via the ROM16(),
ROM32() and ROM64() macros which fault on SPARC (but would be transparently
handled by x86 hardware). Making use of get_unaligned() macro fixes the
problem for me.

nouveau_subdev & misc patches
Hello all, this series includes a wide range of fixes - from a few
month's old one-liners from Andreas Heider regarding vga_switcheroo, via a
null pointer dereference and double memory allocation, to a buffer overflow.
