Subject: [PATCH 0/7] mmc: core: cleanup and locking patches description

Following 7 patches are mostly cleanup with one key patch around host->areq
locking.  The host->areq locking problem description is here:
	http://www.spinics.net/lists/linux-mmc/msg21644.html

I do believe this preposed host->areq locking patch is a complete fix.
But it appears to fix the problem and is better than nothing.

This patch sequence applies clean to linus' 3.12-rc2 branch and only compile
tested in this form. This is a forward port (and cleanup) of the
same patch I've been testing on ChromeOS-3.4 tree using Exynos5250 chipset.

cheers,
grant
