Merge tag 'mmc-merge-for-3.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc

MMC highlights for 3.3:

Core:
 * Support for the HS200 high-speed eMMC mode.
 * Support SDIO 3.0 Ultra High Speed cards.
 * Kill pending block requests immediately if card is removed.
 * Enable the eMMC feature for locking boot partitions read-only
   until next power on, exposed via sysfs.

Drivers:
 * Runtime PM support for Intel Medfield SDIO.
 * Suspend/resume support for sdhci-spear.
 * sh-mmcif now processes requests asynchronously.
