Changes since V3: Adjusted ...blk_end_request...() for new block status codes Fixed CQHCI transaction descriptor for "no DCMD" case Changes since V2: Dropped patches that have been applied. Re-based Added "mmc: sdhci-pci: Add CQHCI support for Intel GLK" Changes since V1: "Share mmc request array between partitions" is dependent on changes in "Introduce queue semantics", so added that and block fixes: Added "Fix is_waiting_last_req set incorrectly" Added "Fix cmd error reset failure path" Added "Use local var for mqrq_cur" Added "Introduce queue semantics" Changes since RFC: Re-based on next. Added comment about command queue priority. Added some acks and reviews.
