The driver needs to always supply the "GRH present" flag to the hypervisor, whether it's true or false. Not supplying it (i.e. not setting the corresponding mask bit) amounts to a "perhaps", which we don't want.

Once upon a time, GPIO interrupts were rare. But then a chip bug in the waldo series forced the use of a GPIO interrupt to signal packet reception. This greatly increased the frequency of GPIO interrupts which have the gpio_mask bits set on the waldo chips. Other bits in the gpio_status register are used for I2C clock and data lines, these bits are usually on. An "unlikely" annotation leftover from the old days was improperly applied to these bits, and an unnecessary chip mmio read was being accessed in the interrupt fast path on waldo. Remove the stagnant unlikely annotation in the interrupt handler and keep a shadow copy of the gpio_mask register to avoid the slow mmio read when testing for interruptable GPIO bits.

This reverts commit 5b479c91. Quoth Neil Brown: "It causes an oops when auto-detecting raid arrays, and it doesn't seem easy to fix. The array may not be 'open' when do_md_run is called, so bdev->bd_disk might be NULL, so bd_set_size can oops. This whole approach of opening an md device before it has been assembled just seems to get more and more painful. I think I'm going to have to come up with something clever to provide both backward comparability with usage expectation, and sane integration into the rest of the kernel."

It is preferable to group drivers by usage (net, scsi, ATA, ...) than by bus. When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer is probably less qualified on networking issues than a networking maintainer. Also, from a practical standpoint, chips often appear on multiple buses, which is why we do not put drivers into drivers/pci/net.

This patch fixes some problems with ADMA-capable controllers with regard to freeze, thaw and irq_clear libata callbacks. Freeze and thaw didn't switch the ADMA-specific interrupts on or off, and more critically the irq_clear function didn't respect the restriction that the notifier clear registers for both ports have to be written at the same time even when only one port is being cleared. This could result in timeouts on one port when error handling (i.e. as a result of hotplug) occurred on the other port. As well, this fixes some issues in the interrupt handler: we shouldn't check any ADMA status if the port has ADMA switched off because of an ATAPI device, and it also checks to see if any ADMA interrupt has been raised even when we are in port-register mode.

There is a known problem with sata_promise on SATAII-150/300 TX4 controller cards: it enumerates drives in an order that differs from the port numbers printed on the controller cards. However, Promise's BIOS and Linux driver both get the order right. I investigated Promise's Linux driver (v1.01.0.23), and found that it explicitly changes the mapping from logical port number to ATA engine MMIO address on the SATAII TX4 cards. It does this on all SATAII TX4 cards, without inspecting revision etc. The SATAII TX2plus cards continue to use the same mapping that was used for the first-generation chips. This patch updates sata_promise to use the new port number to ATA engine mapping on SATAII TX4 cards, which fixes the drive enumeration order problem on those cards. Tested on several 1st and 2nd generation TX2plus and TX4 chips. Signed-off-by: NMikael Pettersson <mikpe@it.uu.se> Signed-off-by: NJeff Garzik <jeff@garzik.org>

The sata_promise error decode update changed pdc_host_intr() to return and not complete the qc after detecting an error. Unfortunately not completing the qc:s causes them to always time out on error, which is wrong and has nasty side-effects. This patch updates pdc_error_intr() to call ata_port_abort(), similar to ahci and sata_sil24. Doing this is important as it makes EH see the original error and not a bogus timeout.

Ejecting a PCMCIA IBM Token Ring card that has not had its dev->open() called will reliably trigger an uninitialized spinlock oops when spinlock debugging is enabled. The system then hangs, occasionally softlockup oopsing. Apparently ibmtr.c:tok_interrupt() doesn't expect to be called before tok_open(), but tok_interrupt() gets called anyway when the card is ejected. So, set an already-existing flag which causes tok_interrupt() to bail out early upon card ejection. Tested by inserting and removing the PCMCIA card several times.

IDE PCI host drivers should register themselves with IDE core only when IDE driver is built-in, otherwise (IDE driver is modular and thus IDE PCI host drivers are also modular) the code has no effect and just complicates the probing. Fix it by adding new config option CONFIG_IDEPCI_PCIBUS (defined only when needed and invisible to the user) and covering by #ifdef/#endif the code in question. It turned out that "ide=reverse" was silently accepted but did nothing in case when IDE driver was modular, this is fixed now. Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>
