I believe you inadvertently used the series file with xscale specific patches. The patch that is causing your compile failures is "iop13xx-pci-sysfs-mmap.patch". Try 'quilt pop -a' then verify that your series file looks like the following: # This series applies on GIT commit 7dcca30a32aadb0520417521b0c44f42d09fe05c iop13xx-add-iop-attr-for-tpmi.patch iop-section-mismatch.patch has-dma-compilation-fix.patch # comment out the following patch for an x86 build #iop13xx-workaround-uart-iir-errata.patch arm-allow-dma-none.patch ioatdma-push-pending-4.patch ioatdma-sysfs-errors.patch ioatdma-kill-register-access-wrappers.patch ioatdma-killwriteq.patch ioatdma-document-tcp_dma_copybreak.patch ioatdma-only-offload-at-context-switch.patch ioatdma-warning-fix.patch ioat-kexec-fix.patch ioat-unisys-pciid.patch dmaengine-dma_async_tx_descriptor-refactor.patch dmaengine-client-channel-management.patch xor-move.patch add-the-async_tx-api.patch raid5-refactor.patch raid5-pr_debug.patch md-add-raid5_run_ops.patch md-enable-raid5_run_ops.patch md-async-write-operations.patch md-async-compute-operations.patch md-async-check-operations.patch md-async-read-operations.patch md-async-expand-operations.patch md-move-io-to-raid5_run_ops.patch md-remove-compute_block-and-compute_parity5.patch iop-adma-device-driver.patch iop13xx-adma-support.patch iop3xx-adma-support.patch arm-add-drivers-dma.patch iop-watchdog.patch i2c-m41st85w.patch iop13xx-imu.patch iop13xx-imu-scsi.patch iop13xx-imu-directed-core-reset.patch iop13xx-xsc3-oprofile.patch # comment out the following patch for an x86 build #iop13xx-pci-sysfs-mmap.patch iop13xx-pmon-oprofile.patch arm-udivdi3.patch pbi_compact_flash.patch # comment out the following patch for an x86 build #dma-copy-clear-page.patch # comment out the following patch for an x86 build #try-dma-memcpy.patch # comment out the following patch for an x86 build #try-dma-copy-to-user.patch # comment out the following patch for an x86 build #try-dma-copy-from-user.patch isc813xx.patch iop-defconfig-update.patch # comment out the following patch for an x86 build #iop-cross-compile-default.patch raid5-stripe-queue-intro.patch raid5-stripe-queue-tree.patch v2.6.22.1-iop1.patch Regards, Dan - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
