optimize SI VM handling + use lower_32_bits where appropriate reverted - the latter just so I could revert the former.
I'll see if I am stable over the next couple of days like this.
I am stable so far with the above reverted.
Spoke too soon, I just locked. Wasn't quite the same as before in that screen stayed on displaying normal rather that off/on + junk.
Wasn't doing anything GPU related (accepting I always am with glamor), was doing a big compile, so memory pressure I guess.
Also just add to the mix, after thinking I was stable yesterday I upgraded gcc and updated llvm and mesa so they were different in several ways, though I haven't rebuilt kernel.
