[PATCH] libata: rework legacy handling to remove much of the cruft
Kill host_set->next Fix simplex support Allow per platform setting of IDE legacy bases Some of this can be tidied further later on, in particular all the legacy port gunge belongs as a PCI quirk/PCI header decode to understand the special legacy IDE rules in the PCI spec. Longer term Jeff also wants to move the request_irq/free_irq out of core which will make this even cleaner. tj: folded in three followup patches - ata_piix-fix, broken-arch-fix and fix-new-legacy-handling, and separated per-dev xfermask into separate patch preceding this one. Folded in fixes are... * ata_piix-fix: fix build failure due to host_set->next removal * broken-arch-fix: add missing include/asm-*/libata-portmap.h * fix-new-legacy-handling: * In ata_pci_init_legacy_port(), probe_num was incorrectly incremented during initialization of the secondary port and probe_ent->n_ports was incorrectly fixed to 1. * Both legacy ports ended up having the same hard_port_no. * When printing port information, both legacy ports printed the first irq.
