* hpt366: set IDE_HFLAG_SERIALIZE in ->host_flags if needed in init_hwif_hpt366(). Remove HPT_SERIALIZE_IO while at it. * Set IDE_HFLAG_SERIALIZE in ->host_flags if needed in ide_init_port(). * Convert init_irq() to use IDE_HFLAG_SERIALIZE together with hwif->host to find out ports which need to be serialized. * Remove no longer needed save_match() and ide_hwif_t.serialized. v2: * Set host's ->host_flags field instead of port's copy. This patch should fix the incorrect grouping of port(s) from host(s) that need serialization with port(s) that happen to use the same IRQ(s) but are from the host(s) that don't need it.

2008-12-29ide: fix IDE ACPI regression breaking suspendBartlomiej Zolnierkiewicz
Commit 4dde4492d850a4c9bcaa92e5bd7f4eebe3e2f5ab ("ide: make drive->id an union (take 2)") accidentally introduced an IDE ACPI regression which at least on some machines confuses ACPI and breaks suspend. Fix it. Fixes kernel.org bug #12279: http://bugzilla.kernel.org/show_bug.cgi?id=12279 [ Sorry about the bug (IDE ACPI is not used by default so it managed to slip in). Still it is kind of surprising that the bug breaks suspend as it shouldn't impact anything except IDE ACPI (it seems that it uncovered either some ACPI/PM deficiency or a BIOS bug). ] Reported-and-bisected-by: David Roka <roka@dawid.hu> Tested-by: David Roka <roka@dawid.hu> Cc: Rafael J.

2008-12-29sata_sil: add Large Block Transfer supportRobert Hancock
This implements support for the Large Block Transfer feature found in Silicon Image 311x controllers. This allows transferring bigger contiguous chunks of data from system memory and avoids the 64KB boundary restriction of standard SFF controllers. This is based on a patch from Jeff Garzik (from the sii-lbt branch of libata-dev) but includes a few bug fixes: Since the bmdma2 register does not implement the status bits, the original bmdma register must be used except where the bmdma2 register is required. As well the DMA boundary should be 31-bit instead of 32-bit since the top bit of the length field is still required for the PRD end-of-table flag.
