The patch titled
s3cmci: make SDIO IRQ hardware IRQ support build-time configurable
has been removed from the -mm tree. Its filename was
s3cmci-make-sdio-irq-hardware-irq-support-build-time-configurable.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: s3cmci: make SDIO IRQ hardware IRQ support build-time configurable
From: Ben Dooks <[email protected]>
We have found a couple of boards where the SDIO IRQ hardware support has
failed to work properly, and thus we should make it configurable whether
or not to be included in the driver.
