This patch series removes all instances of mach/vmalloc.h in order to
have a more unified memory map across all ARM architectures. To do so,
the static mappings are moved inside the vmalloc area. And finally this
allows for a generic optimization to ioremap where static mappings are
reused whenever possible, using common code instead of having this
duplicated in a couple places.
This also provides a net reduction of more than 1200 lines of code.
One regression was discovered on shmobile during testing because that
platform asks for 158MB of consistent DMA memory while the documented
maximum is 14MB. Inspection of the code doesn't tell why this is
required, and listed maintainers did not respond yet after a couple
days. So a temporary exception to the definition of VMALLOC_END was
added for CONFIG_SHMOBILE and a noisy warning to get those maintainers'
attention.
Based on v3.1-rc4.
