2011-10-07igb: push data into first igb_tx_buffer sooner to reduce stack usageAlexander Duyck
Instead of storing most of the data for the TX hot path in the stack until we are ready to write the descriptor we can save ourselves some time and effort by pushing the SKB, tx_flags, gso_size, bytecount, and protocol into the first igb_tx_buffer since that is where we will end up putting it anyway.

2011-10-08ata: irq: Remove IRQF_DISABLEDYong Zhang
Since commit [c58543c8: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed. Signed-off-by: Yong Zhang <yong.zhang0@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2011-10-08pata_sis: add mode_filter method for certain sis5513 chipsetsDan McGee
This mirrors a very old commit (3160d5416f39da9d9, "sis5513: add ->udma_filter method for chipset_family >= ATA_133") to the old sis5513 IDE driver that prevents certain setups from working. UDMA6 (ATA/133) is not supported on some chipsets and we need to ensure this mode is not chosen even if a connected drive supports it. Port this old patch forward to the new PATA driver to ensure UDMA5 is the highest mode used if that is what is supported. Kernel bugzilla #41582.

2011-10-07ata_piix: make DVD Drive recognisable on systems with Intel Sandybridge ↵Ming Lei
chipsets(v2) This quirk patch fixes one kind of bug inside some Intel Sandybridge chipsets, see reports from https://bugzilla.kernel.org/show_bug.cgi?id=40592. Many guys also have reported the problem before: https://bugs.launchpad.net/bugs/737388 https://bugs.launchpad.net/bugs/794642 https://bugs.launchpad.net/bugs/782389 ...... With help from Tejun, the problem is found to be caused by 32bit PIO mode, so introduce the quirk patch to disable 32bit PIO on SATA piix for some Sandybridge CPT chipsets. Seth also tested the patch on all five affected chipsets (pci device ID: 0x1c00, 0x1c01, 0x1d00, 0x1e00, 0x1e01), and found the patch does fix the problem.

2011-10-06igb: Consolidate creation of Tx context descriptors into a single functionAlexander Duyck
This patch is meant to simplify the transmit path by reducing the overhead for creating a transmit context descriptor. The current implementation is split with igb_tso and igb_tx_csum doing two separate implementations on how to setup the tx_buffer_info structure and the tx_desc. By combining them it is possible to reduce code and simplify things since now only one function will create context descriptors.

2011-10-06igb: split buffer_info into tx_buffer_info and rx_buffer_infoAlexander Duyck
In order to be able to improve the performance of the TX path it has been necessary to add addition info to the tx_buffer_info structure. However a side effect is that the structure has gotten larger and this in turn has also increased the size of the RX buffer info structure. In order to avoid this in the future I am splitting the single buffer_info structure into two separate ones and instead I will join them by making the buffer_info pointer in the ring a union of the two.
