The patch titled pata_sil680: only enable MMIO on Cell blades has been removed from the -mm tree. Its filename was pata_sil680-only-enable-mmio-on-cell-blades.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: pata_sil680: only enable MMIO on Cell blades From: Benjamin Herrenschmidt <benh@xxxxxxxxxx> There have been reported regressions of the SIL 680 driver when using MMIO, so this makes it only try MMIO on Cell blades where it's known to be necessary (the host bridge doesn't do PIO on these). We'll try to find the root problem with MMIO separately.
