removed an unused regulator entry, but left the second MMC channel

This causes the SDIO module to fail being detected.
This patch adds the two regulators that actually feed the WLAN module
(1v8 from the TWL4030 VIO LDO, and a fixed 3v3). With that patch, the
second channel is properly detected. Details of the power supply

omap4: l2x0: enable instruction and data prefetching
Enabling L2 prefetching improves performance as shown on Panda
ES2.1 board with mem test, and it has measurable impact on
performances. I think we should consider it, even though it damages
"writes" a bit. (rebased to k.org)
Usually the prefetch is used at both levels together L1 + L2, however,
to enable the CP15 prefetch engines, these are under security, and on
GP devices, we cannot enable it(e.g. on PandaBoard). However, just
enabling PL310 prefetch seems to provide performance improvement,
as shown in the data below (from Ubuntu) and would be a great thing
to pull in.
What prefetch does is enable automatic next line prefetching. With this
enabled, whenever the PL310 receives a cachable read request, it
automatically prefetches the following cache line as well.

Fix IGEPv2 second MMC channel power supply
Commit
72f381ba056 (omap3: Remove VMMC2 regulator on IGEP v2)
removed an unused regulator entry, but left the second MMC channel
(used by the Libertas WLAN module) without link to power regulator.
This causes the SDIO module to fail being detected.
This patch adds the two regulators that actually feed the WLAN module
(1v8 from the TWL4030 VIO LDO, and a fixed 3v3). With that patch, the
second channel is properly detected. Details of the power supply
implementation were kindly provided by Enric Balletbo i Serra.
Also change vmmc1 to use symbolic names instead of direct device
reference.
Tested on an IGEPv2 Rev-B.

Fix by defining three OMAP1-only dummy functions for

Normally, code that is OMAP SoC-revision-specific like this should go
under the arch/arm/*omap* directories, and get abstracted away from
drivers via struct platform_data function pointers. This doesn't work
in this case since there doesn't appear to be any convenient way to access
struct platform_data (or something like it) in the current design of
the sound/soc/omap/omap-mcbsp.c driver.

http://www.spinics.net/lists/linux-omap/msg39560.html

This patch passes build tests for ams_delta_defconfig and omap2plus_defconfig,

bprm_mm_init() also skips the check, and although I don't think this can

i2c_intel_mid: Fix slash in sysfs name
This gets caught by the new sanity check code. Instead of the slash use a
different symbol. This was originally found by Major Lee who proposed a
rather more complex patch which changed the name according to the chip
type.
On the basis that we are in a late -rc and making Linus grumpy isn't always
a good idea (however fun) this is a simple alternative.
