io mapping: clean up #ifdefs
io mapping: improve documentation
i915: use io-mapping interfaces instead of a variety of mapping kludges
resources: add io-mapping functions to dynamically map large device apertures
x86: add iomap_atomic*()/iounmap_atomic() on 32-bit using fixmaps
Impact: add new generic io_map_*() APIs
Graphics devices have large PCI apertures which would consume a significant
fraction of a 32-bit address space if mapped during driver initialization.
Using ioremap at runtime is impractical as it is too slow.
This new set of interfaces uses atomic mappings on 32-bit processors and a
large static mapping on 64-bit processors to provide reasonable 32-bit
performance and optimal 64-bit performance.
The current implementation sits atop the io_map_atomic fixmap-based
mechanism for 32-bit processors.
This includes some editorial suggestions from Randy Dunlap for

ftrace: handle archs that do not support irqs_disabled_flags
Impact: build fix on non-lockdep architectures
Some architectures do not support a way to read the irq flags that
is set from "local_irq_save(flags)" to determine if interrupts were
disabled or enabled. Ftrace uses this information to display to the user
if the trace occurred with interrupts enabled or disabled.
Besides the fact that those archs that do not support this will fail to
compile, unless they fix it, we do not want to have the trace simply
say interrupts were not disabled or they were enabled, without knowing
the real answer.
This patch adds a 'X' in the output to let the user know that the
architecture they are running on does not support a way for the tracer
to determine if interrupts were enabled or disabled. It also lets those
same archs compile with tracing enabled.

The total width of the command name plus spaces should be
8 characters, but were 7 and 9, respectively. With 8 chars,
all commands are now lining up nicely.
The mandocs, psdocs, xmldocs commands are OK.

The documents aren't particularly useful anyway and the hardware in
question has never run anything newer than a v2.2.14 kernel to my
knowledge.
