* virtio: Fix used_idx wrap-aroundAnthony Liguori2007-11-11
| | | | | | | | | | | | The more_used() function compares the vq->vring.used->idx with last_used_idx. Since vq->vring.used->idx is a 16-bit integer, and last_used_idx is an unsigned int, this results in unpredictable behavior when vq->vring.used->idx wraps around. This patch corrects this by changing last_used_idx to the correct type. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

| * | libata: port and host should be stopped before hardware resources are releasedTejun Heo2007-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Port / host stop calls used to be made from ata_host_release() which is called after all hardware resources acquired after host allocation are released. This is wrong as port and host stop routines often access the hardware. Add separate devres for port / host stop which is invoked right after IRQ is released but with all other hardware resources intact. The devres is added iff ->host_stop and/or ->port_stop exist.

| * | libata: skip 0xff polling for PATA controllersTejun Heo2007-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a presentation of true workmanship, pata_ali asserts IRQ permanantly if the TF status register is read more than once when there's no device attached to the port. Avoid waiting polling for !0xff if it's PATA. It's needed only for some rare SATA devices anyway. This problem is reported by Luca Tettamanti in bugzilla bug 9298.

| * | libata: pata_platform: Support polling-mode configuration.Paul Mundt2007-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some SH boards (old R2D-1 boards) have generally not had working CF under libata, due to both buswidth issues (handled by Aoi Shinkai in 43f4b8c7578b928892b6f01d374346ae14e5eb70), and buggy interrupt controllers. For these sorts of boards simply disabling the IRQ and polling ends up working fine. This conditionalizes the IRQ resource for pata_platform and lets platforms that want to use polling mode simply omit the resource entirely.

| * | libata: Support PIO polling-only hosts.Paul Mundt2007-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default ata_host_activate() expects a valid IRQ in order to successfully register the host. This patch enables a special case for registering polling-only hosts that either don't have IRQs or have buggy IRQ generation (either in terms of handling or sensing), which otherwise work fine. Hosts that want to use polling mode can simply set ATA_FLAG_PIO_POLLING and pass in an invalid IRQ. Signed-off-by: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| * | libata sata_qstor workaround for spurious interruptsMark Lord2007-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sata_qstor workaround for spurious interrupts. The qstor hardware generates spurious interrupts from time to time when switching in and out of packet mode. These eventually result in the IRQ being disabled, which kills other devices sharing this IRQ with us. This workaround isn't perfect, but it's about the best we can do for this hardware. Spurious interrupts will still happen, but won't be logged as such, and therefore won't cause the IRQ to be inadvertently disabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The standard validate_addr handler refuses to accept the all zeroes address as valid. However, it's common historical practice for the bonding master to be configured up prior to having any slaves, at which time the master will have a MAC address of all zeroes. Resolved by setting the dev->validate_addr to NULL. The master still can't end up with an invalid address, as the set_mac_address function tests for validity.
