Most drivers need to set length and offset as well, so may as well fold those three lines into one. Add sg_assign_page() for those two locations that only needed to set the page, where the offset/length is set outside of the function context. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

Set bits 0, 4, 5 and 7 of PCI configuration register 0x40 in the quirk. This has the following effects and is recommended by the vendor. * Force enable of IDE channels (used to be left alone as BIOS configured) * Change initial phase behavior of PIO cycle such that the host pulls down the bus instead of tristating it. Vendor recommends this setting. The above settings are better for the current generation of controllers and needed for the upcoming next generation. Tested on JMB363.

Did a complete audit of these and found we have another error case. ata_bus_softreset calls ata_check_status which means that it tries to do an ioread8 on the port blindly and check versus 0xFF for an error. It should of course be using the ap->ops method for this via chk_status, and this bug causes a wrog status call on the NS87415 at least.

Convert mii (link state) monitor to acquire correct locks for failover events. In particular, failovers generally require RTNL at a low level (when manipulating device MAC addresses, for example) and no other locks. The high level monitor is responsible for acquiring a known set of locks, RTNL, the bond->lock for read and the slave_lock for write, and the low level failover processing can then release appropriate locks as needed. This patch provides the high level portion. As it is undesirable to acquire RTNL for every monitor pass (which may occur as often as every 10 ms), the miimon has been converted to do conditional locking. A first pass inspects all slaves to determine if any action is required, and if so, a second pass (after acquring RTNL) is done to perform any actions (doing a complete rescan, as the situation may have changed when all locks were released).

Change locking in balance-rr transmit processing to use a free running counter to determine which slave to transmit on. Instead, a free-running counter is maintained, and modulo arithmetic used to select a slave for transmit. This removes lock operations from the TX path, and eliminates a deadlock introduced by the conversion to work queues.

Convert bonding timers to workqueues. This converts the various monitor functions to run in periodic work queues instead of timers.

Polling currently calls the irq handler, which loops through all the boards, calling the work function for all polling boards with work. irq handling loops through all the boards, finding the specific board that applies to us, and calling the work just for that one board. The two logics are sufficiently different to warrant different functions, rather than being slack and calling the same function in two different ways. This serves to make the interrupt handler a -lot- more efficient. Signed-off-by: NJeff Garzik <jgarzik@redhat.com>

ICP's Wafer 5823 SBC has, as far as I can tell, the same WDT as many, if not all ICP's SBC's (that do have a WDT). I have tested it with several boards, including Rocky 4783, Rocky 3703 and Rocky 3782. I propose a rename of the Wafer 5823 watchdog timer driver to something like "IPC (SBC) Watchdog Timer", to reflect that it works with other IPC boards (maybe even all of them).

For recent ISPs, software during CS_UNDERRUN handling must determine if the two residuals, firmware-calculated and FCP_RSP, are different to recognize if a frame has been dropped. Update the driver to catch this condition, and clear the SS_RESIDUAL_UNDER and lscsi_status bits. This logic is consistent with what earlier firmwares did by explicitly cracking open the FCP_RSP statuses and clearing SS_RESIDUAL_UNDER.

Recent ISPs need only the single MMIO BAR to manipulate HW registers. Unfortunately, ISP21xx, ISP22xx, ISP23xx, and ISP63xx type cards still require the I/O mapped region to manipulate the FLASH via the two HW flash-registers (flash_address and flash_data).
