* libata: IDENTIFY backwards for drive side cable detectionTejun Heo2007-03-28
| | | | | | | | | | | | | | For drive side cable detection to work correctly, drives need to be identified backwards such that the slave device releases PDIAG- before the mater drive tries to detect cable type. ata_bus_probe() was fixed by commit f31f0cc2f0b7527072d94d02da332d9bb8d7d94c but the new EH path wasn't fixed. This patch makes new EH path do IDENTIFY backwards. ata_dev_configure() for new devices are still performed master first. This is to keep the detection messages in forward order.

* ahci.c: walkaround for SB600 SATA internal error issueConke Hu2007-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a HW issue in ATI SB600 SATA that PxSERR.E should not be set on some conditions, for example, when there is no media in SATA CD/DVD drive or media is not ready, AHCI controller fails to execute ATAPI commands and reports PORT_IRQ_TF_ERR, but ATI SB600 SATA controller sets PxSERR.E at the same time, which is not necessary. This patch is just to ignore the INTERNAL ERROR in such case. Without this patch, ahci error handler will report many errors as below: ----------- cut from dmesg ----------- ata9: soft resetting port ata9: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata9.00: configured for UDMA/33 ata9: EH complete ata9.00: exception Emask 0x40 SAct 0x0 SErr 0x800 action 0x2 ata9.00: (irq_stat 0x40000001) ata9.00: cmd a0/00:00:00:00:20/00:00:00:00:00/a0 tag 0 cdb 0x0 data 0 res 51/24:03:00:00:20/00:00:00:00:00/a0 Emask 0x40 (internal error) ata9: soft resetting port ata9: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata9.00: configured for UDMA/33 ata9: EH complete ata9.00: exception Emask 0x40 SAct 0x0 SErr 0x800 action 0x2 ata9.00: (irq_stat 0x40000001) ata9.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x43 data 12 in res 51/24:03:00:00:00/00:00:00:00:00/a0 Emask 0x40 (internal error) -------- end cut --------- Signed-off-by: Conke Hu <conke.hu@amd.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| * [SCSI] gdth: fix oops in gdth_copy_cmd()Joerg Dorchain2007-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent alterations to the gdth_fill_raw_cmd() path no longer set the sg_ranz field for zero transfer commands. However, this field is used lower down in the function to initialise ha->cmd_len to the size of the firmware packet. If this uninitialised field contains a bogus value, ha->cmd_len can become much larger than the actual firmware packet and end up oopsing in gdth_copy_cmd() as it tries to copy this huge packet to the device (usually because it runs into an unallocated page). The fix is to initialise the sg_ranz field to zero at the start of gdth_fill_raw_cmd().

| * [SCSI] mptsas: Fix oops for insmod during kexecJudith Lebzelter2007-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fix's an oops during driver load time. mptsas_probe calls mpt_attach(over in mptbase.c). Inside that call, we read some manufacturing config pages to setup some defaults. While reading the config pages, the firmware doesn't complete the reply in time, and we have a timeout. The timeout results in hardreset handler being called. The hardreset handler calls all the fusion upper layer driver reset callback handlers. The mptsas_ioc_reset function is the callback handler in mptsas.c. So where I'm getting to, is mptsas_ioc_reset is getting called before scsi_host_alloc is called, and the pointer ioc->sh is NULL as well as the hostdata.

So kvm uses virtualized vm86 mode to run real mode code. Unfortunately, this virtualized vm86 mode does not support the so called "big real" mode, where the segment selector and base do not agree with each other according to the real mode rules (base == selector << 4). To work around this, kvm checks whether a selector/base pair violates the virtualized vm86 rules, and if so, forces it into conformance. On a transition back to protected mode, if we see that the guest did not touch a forced segment, we restore it back to the original protected mode value. This pile of hacks breaks down if the gdt has changed in real mode, as it can cause a segment selector to point to a system descriptor instead of a normal data segment. In fact, this happens with the Windows bootloader and the qemu acpi bios, where a protected mode memcpy routine issues an innocent 'pop %es' and traps on an attempt to load a system descriptor. "Fix" by checking if the to-be-restored selector points at a system segment, and if so, coercing it into a normal data segment. The long term solution, of course, is to abandon vm86 mode and use emulation for big real mode. Signed-off-by: Avi Kivity <avi@qumranet.com>

Commit 4aff5e2333c9a1609662f2091f55c3f6fffdad36 from Jens Axboe split struct request ->flags into two parts: cmd_type and cmd_flags. In i2o layer this patch has replaced flag REQ_SPECIAL by the according cmd_type. However i2o has used REQ_SPECIAL not as command type but as driver-specific flag for the debug purposes. As result all i2o requests have type "special" now, are not processed to the hardware and fail with I/O error: i2o/hda:<3>Buffer I/O error on device i2o/hda, logical block 0 Buffer I/O error on device i2o/hda, logical block 0 Buffer I/O error on device i2o/hda, logical block 0 unable to read partition table block-osm: device added (TID: 207): i2o/hda The following patch removes the extra debug checks without any drawbacks and restores the normal driver's work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On most tg3 chips, the memory enable bit in the PCI command register gets cleared during chip reset and must be restored before accessing PCI registers using memory cycles. The chip does not generate interrupt during chip reset, but the irq handler can still be called because of irq sharing or irqpoll. Reading a register in the irq handler can cause a master abort in this scenario and may result in a crash on some architectures. Use the TG3_FLAG_CHIP_RESETTING flag to tell the irq handler to exit without touching any registers. The checking of the flag is in the "slow" path of the irq handler and will not affect normal performance. The msi handler is not shared and therefore does not require checking the flag.

| * | [NET]: Fix neighbour destructor handling.Alexey Kuznetsov2007-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ->neigh_destructor() is killed (not used), replaced with ->neigh_cleanup(), which is called when neighbor entry goes to dead state. At this point everything is still valid: neigh->dev, neigh->parms etc. The device should guarantee that dead neighbor entries (neigh->dead != 0) do not get private part initialized, otherwise nobody will cleanup it. I think this is enough for ipoib which is the only user of this thing. Initialization private part of neighbor entries happens in ipib start_xmit routine, which is not reached when device is down. But it would be better to add explicit test for neigh->dead in any case. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a AP device is unconfigured __ap_poll_all() will call device_unregister() in software interrupt context which can cause dead locks. To fix this the device will be only marked as unconfigured and the device_unregister() call will be done later by either ap_scan_bus() or ap_queue_message() in process context.

This resolves really NASTY problems with logspamming via WARN_ON(), indicating N-page leaks. - Be more correct in handling GET_STATUS request for RECIP_ENDPOINT ... the previous code only handled RECIP_INTERFACE, this version should be correct except for (sigh) bulk/interrupt endpoints. - Provide a better name for the function reporting whether the board has vbus sensing wired up. GET_STATUS requests for endpoint status still acts strangely though, at least given one flakey host doesn't always ack the first DATA packet, then the packet that gets retransmitted doesn't have data!
