This series addresses one commend fix on the table for mtrr_add()
effect on the PAT case when UC- is used. Other than that it is
the same as v4.

Luis R. Rodriguez (6):
x86: add ioremap_uc() - force strong UC, PCD=1, PWT=1
x86: document WC MTRR effects on PAT / non-PAT pages
video: fbdev: atyfb: move framebuffer length fudging to helper
video: fbdev: atyfb: clarify ioremap() base and length used
video: fbdev: atyfb: replace MTRR UC hole with strong UC
video: fbdev: atyfb: use arch_phys_wc_add() and ioremap_wc()
