+Subject: [PATCH] mmc: Add card_quirks module parameter, log quirks
+
+Use mmc_block.card_quirks to override the quirks for all SD or MMC
+cards. The value is a bitfield using the bit positions defined in
+include/linux/mmc/card.h. If the module parameter is placed in the
+kernel command line (or bootargs) stored on the card then, assuming the
+device only has one SD card interface, the override effectively becomes
+card-specific.
