Bing Zhao at Marvell discovered a race in the way that dw_mmc was doing a read-modify-write of the INTMASK register. This 2-patch series attempts to fix the problem using a simple spinlock. In order to do so cleanly, we include a patch to tidy up the way that we disable low power mode when using SDIO interrupts. This patch series was not tested on ToT Linux other than basic compiling and booting, since we don't have the whole Marvell SDIO stack up and running in mainline yet. This series is based on mmc-next (e76b855 mmc: sdhci-esdhc-imx: set actual_clock in clock setting) merged atop mainlinx Linux.
