Problems:
- The documentation lacks hierarchy
- Relocating pages disrupts external links to
the documentation and causes confusion for users
Benefits:
- Users can easily access relocated pages from external resources
- Using redirects frees up

Fix coding style. No functional changes.

Implement framebuffer I/O helpers, such as fb_read*() and fb_write*(),
in the architecture's header file or the generic one.
The common case has been the use of regular I/O functions, such as
__raw_readb() or memset_io(). A few architectures used plain system-
memory reads and writes. Sparc used
Replace include statements for with . Fixes
the coding style: if a header is available in asm/ and linux/, it
is preferable to include the header from linux/. This only affects
a few source files, most of which already include .

The code uses readl() and writel(). Include the header file to
get the declarations.

Update the names of the fb_mem*() helpers to be consistent with their
regular counterparts. Hence, fb_memset() now becomes fb_memset_io(),
fb_memcpy_fromfb() now becomes fb_memcpy_fromio() and fb_memcpy_tofb()
becomes fb_memcpy_toio(). No functional changes.

Fbdev provides helpers for framebuffer I/O, such as fb_readl(),
fb_writel() or fb_memcpy_to_fb(). The implementation of each helper
depends on the architecture, but they are all equivalent to regular
I/O functions of similar names. So use regular functions instead and
move all helpers into
