Re: [PATCH 17/41] fbdev: Add drawing functions forframebuffers in system RAM

	Hi Tony,

quoted

The generic drawing functions (cfbimgblt, cfbcopyarea, 
cfbfillrect) assume
that the framebuffer is in IO memory.  However, we have 3 
drivers (hecubafb,
arcfb, and vfb) where the framebuffer is allocated from 
system RAM (via
vmalloc). Using _raw_read/write and family for these drivers 
(as used in
the cfb* functions) is illegal, especially in other platforms.

This is also true for ps3fb. I'll update the support for that once this
patch has hit mainline.

Bloat. It would be much easier to replace the FB_WRITEL and FB_READL 
macros. Last year I was working on a general solution that I wanted to 
submit but I have been pushing other patches I considered higher priority.
Perhaps I should move them up the que.
