So if CPU usage is drastically increased by this commit (or rather this merge), IMHO that points to a bug somewhere else, but triggered by this merge; possibly in radeon / TTM caching setup or in the x86 PAT memory region tracking code.

Seems like that is the case... VM_PFNMAP usage instead of VM_MIXEDMAP triggers that i now need 'nopat' boot option it is also workaround...

So only 'nopat' option work here good with VM_PFNMAP or like before VM_MIXEDMAP is good with PAT... VM_PFNMAP with PAT here is really unusable for gl videos :).
