2008-03-17virtio: fix race in enable_cbChristian Borntraeger
There is a race in virtio_net, dealing with disabling/enabling the callback. I saw the following oops: kernel BUG at /space/kvm/drivers/virtio/virtio_ring.c:218! illegal operation: 0001 [#1] SMP Modules linked in: sunrpc dm_mod CPU: 2 Not tainted 2.6.25-rc1zlive-host-10623-gd358142-dirty #99 Process swapper (pid: 0, task: 000000000f85a610, ksp: 000000000f873c60) Krnl PSW : 0404300180000000 00000000002b81a6 (vring_disable_cb+0x16/0x20) R:0 T:1 IO:0 EX:0 Key:0 M:1 W:0 P:0 AS:0 CC:3 PM:0 EA:3 Krnl GPRS: 0000000000000001 0000000000000001 0000000010005800 0000000000000001 000000000f3a0900 000000000f85a610 0000000000000000 0000000000000000 0000000000000000 000000000f870000 0000000000000000 0000000000001237 000000000f3a0920 000000000010ff74 00000000002846f6 000000000fa0bcd8 Krnl Code: 00000000002b819a: a7110001 tmll %r1,1 00000000002b819e: a7840004 brc 8,2b81a6 00000000002b81a2: a7f40001 brc 15,2b81a4 >00000000002b81a6: a51b0001 oill %r1,1 00000000002b81aa: 40102000 sth %r1,0(%r2) 00000000002b81ae: 07fe bcr 15,%r14 00000000002b81b0: eb7ff0380024 stmg %r7,%r15,56(%r15) 00000000002b81b6: a7f13e00 tmll %r15,15872 Call Trace: ([<000000000fa0bcd0>] 0xfa0bcd0) [<00000000002b8350>] vring_interrupt+0x5c/0x6c [<000000000010ab08>] do_extint+0xb8/0xf0 [<0000000000110716>] ext_no_vtime+0x16/0x1a [<0000000000107e72>] cpu_idle+0x1c2/0x1e0 The problem can be triggered with a high amount of host->guest traffic. I think its the following race: poll says netif_rx_complete poll calls enable_cb enable_cb opens the interrupt mask a new packet comes, an interrupt is triggered----\ enable_cb sees that there is more work | enable_cb disables the interrupt | . V . interrupt is delivered . skb_recv_done does atomic napi test, ok some waiting disable_cb is called->check fails->bang! . poll would do napi check poll would do disable_cb The fix is to let enable_cb not disable the interrupt again, but expect the caller to do the cleanup if it returns false. In that case, the interrupt is only disabled, if the napi test_set_bit was successful.

2008-03-15ACPI: Remove ACPI_CUSTOM_DSDT_INITRD optionLinus Torvalds
This essentially reverts commit 71fc47a9adf8ee89e5c96a47222915c5485ac437 ("ACPI: basic initramfs DSDT override support"), because the code simply isn't ready. It did ugly things to the init sequence to populate the rootfs image early, but that just ended up showing other problems with the whole approach. The fact is, the VFS layer simply isn't initialized this early, and the relevant ACPI code should either run much later, or this shouldn't be done at all. For 2.6.25, we'll just pick the latter option. We can revisit this concept later if necessary.

Currently, we do nothing to guarantee we have a consistent DMA buffer for asynchronous receive packets. Rather than doing several sync's following a dma_map_single() to get consistent buffers, just switch to using dma_alloc_coherent().

2008-03-14firewire: fw-sbp2: set single-phase retry_limitJarod Wilson
Per the SBP-2 specification, all SBP-2 target devices must have a BUSY_TIMEOUT register. Per the 1394-1995 specification, the retry_limt portion of the register should be set to 0x0 initially, and set on the target by a logged in initiator (i.e., a Linux host w/firewire controller(s)). Well, as it turns out, lots of devices these days have actually moved on to starting to implement SBP-3 compliance, which says that retry_limit should default to 0xf instead (yes, SBP-3 stomps directly on 1394-1995, oops). Prior to this change, the firewire driver stack didn't touch retry_limit, and any SBP-3 compliant device worked fine, while SBP-2 compliant ones were unable to retransmit when the host returned an ack_busy_X, which resulted in stalled out I/O, eventually causing the SCSI layer to give up and offline the device. The simple fix is for us to set retry_limit to 0xf in the register for all devices (which actually matches what the old ieee1394 stack did). Prior to this change, a hard disk behind an SBP-2 Prolific PL-3507 bridge chip would routinely encounter buffer I/O errors and wind up offlined by the SCSI layer. With this change, I've encountered zero I/O failures moving tens of GB of data around. Signed-off-by: Jarod Wilson <jwilson@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

2008-03-14firewire: fw-ohci: PPC PMac platform codeStefan Richter
Copied from ohci1394.c. This code is necessary to prevent machine check exceptions when reloading or resuming the driver. Tested on a 1st generation PowerBook G4 Titanium, which also needs the pci_probe() hunk. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> I was able to reproduce the system exception on resume with a 3rd-gen Titanium PowerBook G4 667, and this patch does let the system resume successfully now. Not quite clear if there was possibly an updated version coming using pci_enable_device() instead of the pair of pmac_call_feature() calls, but either way, this is a definite must-have, at least for older ppc macs -- my Aluminum PowerBook G4/1.67 suspends and resumes without this patch just fine.

2008-03-13[POWERPC] Fix viodasd driver with scatterlist debugBenjamin Herrenschmidt
The iSeries viodasd drivers does some very strange things with scatterlists, one of these causing a BUG_ON to trigger when scatterlist debugging is enabled due to initializing the scatterlist with memset instead of sg_init_table(). This fixes it by using sg_init_table(). The rest of the stuff it does to that poor list is still pretty awful but it will work. I may look into fixing things in a nicer way some other time.

2008-03-13[POWERPC] Fix build of modular drivers/macintosh/apm_emu.cGuido Guenther
Currently, if drivers/macintosh/apm_emu is a module and the config doesn't have CONFIG_SUSPEND we get: ERROR: "pmu_batteries" [drivers/macintosh/apm_emu.ko] undefined! ERROR: "pmu_battery_count" [drivers/macintosh/apm_emu.ko] undefined! ERROR: "pmu_power_flags" [drivers/macintosh/apm_emu.ko] undefined! on PPC32. The variables aren't wrapped in '#if defined(CONFIG_SUSPEND)' so we probably shouldn't wrap the exports either. This removes the CONFIG_SUSPEND part of the export, which fixes compilation on ppc32.

2008-03-13[POWERPC] Fix sleep on some powerbooksBenjamin Herrenschmidt
The PMU backlight code would kick in during sleep/resume even on machines that use a different backlight method. This breaks sleep on some PowerBooks. This fixes it by adding a flag to indicate whether the backlight is controlled by the PMU, and testing that before trying to use the PMU to turn off the backlight during sleep.

2008-03-12ACPI: buffer array too short in drivers/acpi/system.cJohann Felix Soden
Since "ff_gbl_lock" has a length of 11 chars and is copied with sprintf to char buffer[10], there is a problem. We need char buffer[12] because of the closing zero byte. Signed-off-by: Johann Felix Soden <johfel@users.sourceforge.net> Signed-off-by: Len Brown <len.brown@intel.com>
