      "message": "libata: use ata_exec_internal() for PMP register access\n\nPMP registers used to be accessed with dedicated accessors -\u003epmp_read\nand -\u003epmp_write.  During reset, those callbacks are called with the\nport frozen so they should be able to run without depending on\ninterrupt delivery.  To achieve this, they were implemented polling.\n\nHowever, as resetting the host port makes the PMP to isolate fan-out\nports until SError.X is cleared, resetting fan-out ports while port is\nfrozen doesn\u0027t buy much additional safety.\n\nThis patch updates libata PMP support such that PMP registers are\naccessed using regular ata_exec_internal() mechanism and kills\n-\u003epmp_read/write() callbacks.  The following changes are made.\n\n* PMP access helpers - sata_pmp_read_init_tf(), sata_pmp_read_val(),\n  sata_pmp_write_init_tf() are folded into sata_pmp_read/write() which\n  are now standalone PMP register access functions.\n\n* sata_pmp_read/write() returns err_mask instead of rc.  This is\n  consistent with other functions which issue internal commands and\n  allows more detailed error reporting.\n\n* ahci interrupt handler is modified to ignore BAD_PMP and\n  spurious/illegal completion IRQs while reset is in progress.  These\n  conditions are expected during reset.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n"

      "message": "libata-pmp: implement Port Multiplier support\n\nImplement Port Multiplier support.  To support PMP, a LLDD has to\nsupply ops-\u003epmp_read() and pmp_write().  If non-null, -\u003epmp_attach and\n-\u003epmp_detach are called on PMP attach and detach, respectively.\n\n-\u003epmp_read/write() can be called while the port is frozen, so they\nmust be implemented by polling.  This patch supplies several helpers\nto ease -\u003epmp_read/write() implementation.\n\nAlso, irq_handler and error_handler must be PMP aware.  Most of PMP\naware EH can be done by calling ata_pmp_do_eh() with appropriate\nmethods.  PMP EH uses separate set of reset methods and this patch\nimplements standard prereset, hardreset and postreset methods.\n\nThis patch only implements PMP support.  The next patch will integrate\nPMP into the reset of libata and thus enable PMP support.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\n"
