+Subject: [PATCH] fix-glamo-mci-defeat-ops-during-suspend.patch
+
+We need to be able to use the config option CONFIG_MMC_UNSAFE_RESUME that allows the rootfs
+to live on SD.  But when we use this, it tries to send a reset command to the SD card during
+suspend -- and unfortunately many things like Power have suspended by then.
+
+This patch again rejects IO on the MMC device during suspend of the MMC device, and it
+gives the result the rootfs on SD card works okay.
