Merge branch 'linux-3.19' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-next
- Tegra K1 voltage support, and coherency improvements
- GM204 support (modesetting, still waiting on NVIDIA for signed fw to
proceed further), and a lot of bios/i2c/devinit adjustments needed to
support it
- GT21x memory reclocking work

drm/nouveau/bios: translate ramcfg strap through M0203
A machine has been spotted where the ramcfg strap is "8", and the ramcfg
xlat table goes 0-7,0-7, resulting in us selecting config 0 for memory
items. On this particular system, config "8" is available and supposed
to be used. It appears that starting from GT21x (where Mv2 appears),
we're supposed to use the value in this table instead.
One concern here is that not all the places we currently use ramcfg xlat
are supposed to be treated the same now. The strap xlat table wasn't
removed from the vbios either, presumably for some kind of good reason.

On architectures for which access to GPU memory is non-coherent,
caches need to be flushed and invalidated explicitly when BO control

MIPS: tlbex: Fix potential HTW race on TLBL/M/S handlers
There is a potential race when probing the TLB in TLBL/M/S exception
handlers for a matching entry. Between the time we hit a TLBL/S/M
exception and the time we get to execute the TLBP instruction, the
HTW may have replaced the TLB entry we are interested in hence the TLB
probe may fail. However, in the existing handlers, we never checked the
status of the TLBP (ie check the result in the C0/Index register). We
fix this by adding such a check when the core implements the HTW. If
we couldn't find a matching entry, we return back and try again.
