Impact: unification
This patch unify fixmap_32.h and fixmap_64.h into fixmap.h.
Things that we can't merge now are using CONFIG_X86_{32,64}
(e.g.:vsyscall and EFI)

x86: use early_ioremap in __acpi_map_table2009-02-09T12:33:51+00:00Jeremy Fitzhardingejeremy@goop.org2009-02-07T23:39:38+00:00urn:sha1:1c14fa4937eb73509e07ac12bf8db1fdf4c42a59
__acpi_map_table() effectively reimplements early_ioremap(). Rather
than have that duplication, just implement it in terms of
early_ioremap().
However, unlike early_ioremap(), __acpi_map_table() just maintains a
single mapping which gets replaced each call, and has no corresponding
unmap function. Implement this by just removing the previous mapping
each time its called. Unfortunately, this will leave a stray mapping
at the end.

x86: add iomap_atomic*()/iounmap_atomic() on 32-bit using fixmaps2008-10-31T09:12:38+00:00Keith Packardkeithp@keithp.com2008-10-31T02:37:09+00:00urn:sha1:fd9409343521eac22b6ed51686128a643c7c976b
Impact: introduce new APIs, separate kmap code from CONFIG_HIGHMEM
This takes the code used for CONFIG_HIGHMEM memory mappings except that
it's designed for dynamic IO resource mapping.
These fixmaps are available even with CONFIG_HIGHMEM turned off.

x86: Fix ASM_X86__ header guards2008-10-23T05:55:23+00:00H. Peter Anvinhpa@zytor.com2008-10-23T05:26:29+00:00urn:sha1:1965aae3c98397aad957412413c07e97b1bd4e64
Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:
a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.
