[v2,0/8] FWNMI fixes / changes

Hi,

Since v1, I fixed the intermediate compile error spotted by Greg, and
rediffed the series on top of ppc-for-5.0, plus Alexey's patch
("spapr/rtas: Reserve space for RTAS blob and log").

The first 6 patches are otherwise unchanged since last posting.

Patch 7 implements fwnim sreset interrupts now in a way that's
compatible with existing Linux guests (which doesn't necessarily quite
match PAPR, but does match PowerVM behaviour).

Patch 8 isn't required but it papers over Linux warning messages caused
by another quirk.

Thanks,
Nick
