Konstantin Belousov be4bf62684 Write-combine framebuffer writes through user-space mappings, if possible.
Note that KVA mapping of the framebuffer already uses write-combining
mode, so the change, besides improving speed of user mode writes, also
satisfies requirement of the IA32 architecture of using consistent
caching modes for multiple mappings of the same page.
