Winbond W83759A controller is fully supported by pata_legacy driver so remove no longer needed pata_winbond driver.

'make htmldocs' has a fatal error when processing libata.xml, as seen below. The string "Example patterns:" (or any string with "example.*:" in it AFAIK) causes some part of the doc generation tool chain to try to produce an <informalexample> block without a beginning <para>, but there is an ending </para> generated, which throws things out of kilter. I don't even know where (what program) this is happening in. I searched in docproc and xmlto and in some XML stylesheets without finding anything. If anyone can give me pointers about this, please do. Until this is fixed, let's just spell "Example" as "Sample" and match up the double quotation marks while there.

Remove the current bio flags and reuse the request flags for the bio, too. This allows to more easily trace the type of I/O from the filesystem down to the block driver. There were two flags in the bio that were missing in the requests: BIO_RW_UNPLUG and BIO_RW_AHEAD. Also I've renamed two request flags that had a superflous RW in them. Note that the flags are in bio.h despite having the REQ_ name - as blkdev.h includes bio.h that is the only way to go for now.

SIDPR window registers are shared across ports and as each access is done in two steps, accesses to different ports under EH may race. This primarily is caused by incorrect host locking in EH context and should be fixed by defining locking requirements for each EH operation which can be used during EH and enforcing them but for now work around the problem by adding a dedicated SIDPR lock and grabbing it for each SIDPR access.

The driver is using platform_driver_probe() during initialization, so ahci_driver.probe hook is never used. But it causes the following (harmless, luckily) section mismatch: WARNING: vmlinux.o(.data+0x2fb20): Section mismatch in reference from the variable ahci_driver to the function .init.text:ahci_probe() This patch removes the ahci_driver.probe assignment, thus fixes the warning. p.s. Note that there's another patch[1] from Rene Bolldorf that tried to solve the same issue by __refdata annotation. __refdata says that this reference is actually OK, but in fact it is not OK, because dereferencing .probe() will cause problems. So the proper fix is to remove the assignment.

libata has two concurrency related limitations. a. ata_wq which is used for polling PIO has single thread per CPU. If there are multiple devices doing polling PIO on the same CPU, they can't be executed simultaneously. b. ata_aux_wq which is used for SCSI probing has single thread. In cases where SCSI probing is stalled for extended period of time which is possible for ATAPI devices, this will stall all probing. #a is solved by increasing maximum concurrency of ata_wq. Please note that polling PIO might be used under allocation path and thus needs to be served by a separate wq with a rescuer. #b is solved by using the default wq instead and achieving exclusion via per-port mutex.

Implement ata_scsi_unlock_native_capacity() which will be called through SCSI layer when block layer notices that partitions on a device extend beyond the end of the device. It requests EH to unlock HPA, waits for completion and returns the current device capacity. This allows libata to unlock HPA on demand instead of having to decide whether to unlock upfront. Unlocking on demand is safer than unlocking by upfront because some BIOSes write private data to the area beyond HPA limit. This was suggested by Ben Hutchings.
