Add the two standard UART signals (GPIO46_STUART_RXD, GPIO47_STUART_TXD) to the
initial mfp config table hx4700_pin_config[] passed to pxa2xx_mfp_config().
Although pxa2xx_transceiver_mode() can subsequently set these two signals via
its own call to pxa2xx_mfp_config(), pxa2xx_transceiver_mode() is only present
when CONFIG_PXA_FICP=y. Hence this patch provides a default mfp config.

At this moment, it can only works in device mode, because when works in

at this moment. Once the vbus driver is added, I'll prepar another

1. Set the WAKEUP_ON_EDGE_RISE MFP config bits for GPIO12 in

Commit c79396c191 ("mmc: sdhci: prevent card detection activity
for non-removable cards") disables card detection where the cards
are marked as non-removable.
This makes sense, but the implementation detail of calling
mmc_card_is_removable() causes some problems, because
mmc_card_is_removable() is overloaded with CONFIG_MMC_UNSAFE_RESUME
semantics.
In the OLPC XO case, we need CONFIG_MMC_UNSAFE_RESUME because our root
filesystem is stored on SD, but we also have external SD card slots
where we want automatic card detection.
Refine the check to only apply to hosts marked as MMC_CAP_NONREMOVABLE,
which is defined to mean that the card is *really* nonremovable. This
could be revisited in future if we find a way to improve
CONFIG_MMC_UNSAFE_RESUME semantics.

This continues the theme started with vm_brk() and vm_munmap():
vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.
This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have
to export our internal do_mmap_pgoff() function.
Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead. We're actually
very close to that already, with the notable exception of the (broken)
use in i810, and a couple of stragglers in binfmt_elf.

of_have_populated_dt() is not expected to be used in drivers but
instead only in early platform init code.
Drivers on the other hand should rely on dev->of_node or of_match_device().
Besides usage of of_have_populated_dt() also throws up build error as below
which was reported by Balaji TK, when omap_hsmmc is built as a module.
ERROR: "allnodes" [drivers/mmc/host/omap_hsmmc.ko] undefined!

eMMC v4.5 discard operation is significantly different from the
existing trim operation because it is not guaranteed to work with
the new sanitize operation. Consequently mmc_can_trim() is
separated from mmc_can_discard().
Also the new discard operation does not result in the sectors being
set to all-zeros, so discard_zeroes_data must not be set.
In addition, the new discard has the same timeout as trim, but from
v4.5 trim is defined to use the hc timeout. The timeout calculation
is adjusted accordingly.
