libata: fix ata_pio_sector for CONFIG_HIGHMEM

2021-08-12T11:21:04Z

[ Upstream commit ecef6a9effe49e8e2635c839020b9833b71e934c ] Data transfers are not required to be block aligned in memory, so they span two pages. Fix this by splitting the call to >sff_data_xfer into two for that case. This has been broken since the initial libata import before the damn of git, but was uncovered by the legacy ide driver removal.

ata: ahci_sunxi: Disable DIPM

2021-07-19T06:53:15Z

commit f6bca4d91b2ea052e917cca3f9d866b5cc1d500a upstream. DIPM is unsupported or broken on sunxi. Trying to enable the power management policy med_power_with_dipm on an Allwinner A20 SoC based board leads to immediate I/O errors and the attached SATA disk disappears from the /dev filesystem. A reset (power cycle) is required to make the SATA controller or disk work again. The A10 and A20 SoC data sheets and manuals don't mention DIPM at all [1], so it's fair to assume that it's simply not supported. But even if it was, it should be considered broken and best be disabled in the ahci_sunxi driver.

pata_ep93xx: fix deferred probing

2021-07-14T14:53:21Z

[ Upstream commit 5c8121262484d99bffb598f39a0df445cecd8efb ] The driver overrides the error codes returned by platform_get_irq() to -ENXIO, so if it returns -EPROBE_DEFER, the driver would fail the probe permanently instead of the deferred probing.

pata_octeon_cf: avoid WARN_ON() in ata_host_activate()

2021-07-14T14:53:21Z

[ Upstream commit bfc1f378c8953e68ccdbfe0a8c20748427488b80 ] Iff platform_get_irq() fails (or returns IRQ0) and thus the polling mode has to be used, ata_host_activate() hits the WARN_ON() due to 'irq_handler' parameter being non-NULL if the polling mode is selected. Let's only set the pointer to the driver's IRQ handler if platform_get_irq() returns a valid IRQ # -- this should avoid the unnecessary WARN_ON()...

sata_mv: add IRQ checks

2021-05-14T07:44:24Z

[ Upstream commit e6471a65fdd5efbb8dd2732dd0f063f960685ceb ] The function mv_platform_probe() neglects to check the results of the calls to platform_get_irq() and irq_of_parse_and_map() and blithely passes them to ata_host_activate() -- while the latter only checks for IRQ0 (treating it as a polling mode indicattion) and passes the negative values to devm_request_irq() causing it to fail as it takes unsigned values for the IRQ #... Add to mv_platform_probe() the proper IRQ checks to pass the positive IRQ #s to ata_host_activate(), propagate upstream the negative error codes, and override the IRQ0 with -EINVAL (as we don't want the polling mode).
