Merge tag 'mmc-merge-for-3.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc

Pull MMC updates from Chris Ball:

Core:
 * Support for MMC 4.5 Data Tag feature -- we tag REQ_META, so devices
   that support Data Tag will provide increased throughput for metadata.
 * Faster detection of card removal on I/O errors.

Drivers:
 * dw_mmc now supports eMMC Power Off Notify, has PCI support, and
   implements pre_req and post_req for asynchronous requests.
 * omap_hsmmc now supports device tree.
 * esdhc now has power management support.
 * sdhci-tegra now supports Tegra30 devices.
 * sdhci-spear now supports hibernation.
 * tmio_mmc now supports using a GPIO for card detection.
 * Intel PCH now supports 8-bit bus transfers.
