Re: [Linux-fbdev-devel] Re: [PATCH] fbdev: Fix IO access in rivafb

In big endian machines, the read*/write* accessors do a byteswap for an
inherently little endian PCI bus.  However, rivafb puts the hardwire in big
endian register access, thus the byteswap is not needed. So for 16- and
32-bit access, instead of read*/write*, use __raw_read*/__raw_write* for all
archs.

Ok, applied with some further simplifications (use "void __iomem *" and 
suddenly those /2 and /4 just go away - also use __raw_xxxx for the 
single-byte versions to be consistent).
