2010-08-29firewire: ohci: work around VIA and NEC PHY packet reception bugStefan Richter
VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write packet event codes for received PHY packets (or perhaps write evt_no_status, hard to tell). Work around it by overwriting the packet's ACK by ack_complete, so that upper layers that listen to PHY packet reception get to see these packets. (Also tested: TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643, JMicron JMB381 --- these do not exhibit this bug.) Clemens proposed a quirks flag for that, IOW whitelist known misbehaving controllers for this workaround. Though to me it seems harmless enough to enable for all controllers. The log_ar_at_event() debug log will continue to show the original status from the DMA unit.

2010-08-26amd64_edac: Do not report error overflow as a separate errorBorislav Petkov
When the Overflow MCi_STATUS bit is set, EDAC reports the lost error with a "no information available" message which often puzzles users parsing the dmesg. This doesn't make much sense since this error has been lost anyway so no need for reporting it separately. Thus, report the overflow bit setting in the MCE dump instead. While at it, remove reporting of MiscV and ErrorEnable (en) which are superfluous. Now it looks like this: [ 1501.650024] MC4_STATUS: Corrected error, other errors lost: yes, CPU context corrupt: no, CECC Error [ 1501.666887] Northbridge Error, node 2 Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

Fix DSM/TRIM commands in sata_mv (v2). These need to be issued using old-school "BM DMA", rather than via the EDMA host queue. Since the chips don't have proper BM DMA status, we need to be more careful with setting the ATA_DMA_INTR bit, since DSM/TRIM often has a long delay between "DMA complete" and "command complete".

2010-08-25hwmon: (k8temp) Differentiate between AM2 and ASB1Andreas Herrmann
Commit 8bf0223ed515be24de0c671eedaff49e78bebc9c (hwmon, k8temp: Fix temperature reporting for ASB1 processor revisions) fixed temperature reporting for ASB1 CPUs. But those CPU models (model 0x6b, 0x6f, 0x7f) were packaged both as AM2 (desktop) and ASB1 (mobile). Thus the commit leads to wrong temperature reporting for AM2 CPU parts. The solution is to determine the package type for models 0x6b, 0x6f, 0x7f. This is done using BrandId from CPUID Fn8000_0001_EBX[15:0].

2010-08-24phylib: Fix race between returning phydev and calling adjust_linkAnton Vorontsov
It is possible that phylib will call adjust_link before returning from {,of_}phy_connect(), which may cause the following [very rare, though] oops upon reopening the device: Unable to handle kernel paging request for data at address 0x0000024c Oops: Kernel access of bad area, sig: 11 [#1] PREEMPT SMP NR_CPUS=2 LTT NESTING LEVEL : 0 P1021 RDB Modules linked in: NIP: c0345dac LR: c0345dac CTR: c0345d84 TASK = dffab6b0[30] 'events/0' THREAD: c0d24000 CPU: 0 [...] NIP [c0345dac] adjust_link+0x28/0x19c LR [c0345dac] adjust_link+0x28/0x19c Call Trace: [c0d25f00] [000045e1] 0x45e1 (unreliable) [c0d25f30] [c036c158] phy_state_machine+0x3ac/0x554 [...] Here is why. Drivers store phydev in their private structures, e.g. gianfar driver: static int init_phy(struct net_device *dev) { ... priv->phydev = of_phy_connect(...); ... } So that adjust_link could retrieve it back: static void adjust_link(struct net_device *dev) { ... struct phy_device *phydev = priv->phydev; ... } If the device has been opened before, then phydev->state is set to PHY_HALTED (or undefined if the driver didn't call phy_stop()). Now, phy_connect starts the PHY state machine before returning phydev to the driver: phy_start_machine(phydev, NULL); if (phydev->irq > 0) phy_start_interrupts(phydev); return phydev; The time between 'phy_start_machine()' and 'return phydev' is undefined. The start machine routine delays execution for 1 second, which is enough for most cases. But under heavy load, or if you're unlucky, it is quite possible that PHY state machine will execute before phy_connect() returns, and so adjust_link callback will try to dereference phydev, which is not yet ready. To fix the issue, simply initialize the PHY's state to PHY_READY during phy_attach(). This will ensure that phylib won't call adjust_link before phy_start().

2010-08-24xen: handle events as edge-triggeredJeremy Fitzhardinge
Xen events are logically edge triggered, as Xen only calls the event upcall when an event is newly set, but not continuously as it remains set. As a result, use handle_edge_irq rather than handle_level_irq. This has the important side-effect of fixing a long-standing bug of events getting lost if: - an event's interrupt handler is running - the event is migrated to a different vcpu - the event is re-triggered The most noticable symptom of these lost events is occasional lockups of blkfront. Many thanks to Tom Kopec and Daniel Stodden in tracking this down.

2010-08-24xen: use percpu interrupts for IPIs and VIRQsJeremy Fitzhardinge
IPIs and VIRQs are inherently per-cpu event types, so treat them as such: - use a specific percpu irq_chip implementation, and - handle them with handle_percpu_irq This makes the path for delivering these interrupts more efficient (no masking/unmasking, no locks), and it avoid problems with attempts to migrate them.

2010-08-243c59x: Fix deadlock between boomerang_interrupt and boomerang_start_txNeil Horman
If netconsole is in use, there is a possibility for deadlock in 3c59x between boomerang_interrupt and boomerang_start_xmit. Both routines take the vp->lock, and if netconsole is in use, a pr_* call from the boomerang_interrupt routine will result in the netconsole code attempting to trnasmit an skb, which can try to take the same spin lock, resulting in deadlock. The fix is pretty straightforward. This patch allocats a bit in the 3c59x private structure to indicate that its handling an interrupt. If we get into the transmit routine and that bit is set, we can be sure that we have recursed and will deadlock if we continue, so instead we just return NETDEV_TX_BUSY, so the stack requeues the skb to try again later.
