2010-08-25ceph: Fix warningsAlan Cox1-5/+9
Just scrubbing some warnings so I can see real problem ones in the build noise. For 32bit we need to coax gcc politely into believing we really honestly intend to the casts. Using (u64)(unsigned long) means we cast from a pointer to a type of the right size and then extend it. This stops the warning spew.

2010-08-25hwmon: (k8temp) Differentiate between AM2 and ASB1Andreas Herrmann1-3/+32
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].

2010-08-25tcp: Combat per-cpu skew in orphan tests.David S. Miller3-12/+19
As reported by Anton Blanchard when we use percpu_counter_read_positive() to make our orphan socket limit checks, the check can be off by up to num_cpus_online() * batch (which is 32 by default) which on a 128 cpu machine can be as large as the default orphan limit itself.

2010-08-25ceph: maintain i_head_snapc when any caps are dirty, not just for dataSage Weil4-7/+26
We used to use i_head_snapc to keep track of which snapc the current epoch of dirty data was dirtied under. It is used by queue_cap_snap to set up the cap_snap. However, since we queue cap snaps for any dirty caps, not just for dirty file data, we need to keep a valid i_head_snapc anytime we have dirty|flushing caps. This fixes a NULL pointer deref in queue_cap_snap when writing back dirty caps without data (e.g., snaptest-authwb.sh). Signed-off-by: Sage Weil <sage@newdream.net>

2010-08-25phylib: Fix race between returning phydev and calling adjust_linkAnton Vorontsov1-0/+2
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 Fitzhardinge1-1/+1
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.

2010-08-243c59x: Fix deadlock between boomerang_interrupt and boomerang_start_txNeil Horman1-1/+14
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.

2010-08-24[S390] fix tlb flushing vs. concurrent /proc accessesMartin Schwidefsky8-6/+28
The tlb flushing code uses the mm_users field of the mm_struct to decide if each page table entry needs to be flushed individually with IPTE or if a global flush for the mm_struct is sufficient after all page table updates have been done. The comment for mm_users says "How many users with user space?" but the /proc code increases mm_users after it found the process structure by pid without creating a new user process. Which makes mm_users useless for the decision between the two tlb flusing methods. The current code can be confused to not flush tlb entries by a concurrent access to /proc files if e.g. a fork is in progres. The solution for this problem is to make the tlb flushing logic independent from the mm_users field. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2010-08-24sparc64: Get rid of indirect p1275 PROM call buffer.David S. Miller7-297/+456
This is based upon a report by Meelis Roos showing that it's possible that we'll try to fetch a property that is 32K in size with some devices. With the current fixed 3K buffer we use for moving data in and out of the firmware during PROM calls, that simply won't work. In fact, it will scramble random kernel data during bootup. The reasoning behind the temporary buffer is entirely historical. It used to be the case that we had problems referencing dynamic kernel memory (including the stack) early in the boot process before we explicitly told the firwmare to switch us over to the kernel trap table. So what we did was always give the firmware buffers that were locked into the main kernel image. But we no longer have problems like that, so get rid of all of this indirect bounce buffering. Besides fixing Meelis's bug, this also makes the kernel data about 3K smaller. It was also discovered during these conversions that the implementation of prom_retain() was completely wrong, so that was fixed here as well. Currently that interface is not in use.

2010-08-24powerpc: Fix config dependency problem with MPIC_U3_HT_IRQSAndreas Schwab1-2/+1
MPIC_U3_HT_IRQS is selected both by PPC_PMAC64 and PPC_MAPLE, but depends on PPC_MAPLE, so a PPC_PMAC64-only config gets this warning: warning: (PPC_PMAC64 && PPC_PMAC && POWER4 || PPC_MAPLE && PPC64 && PPC_BOOK3S) selects MPIC_U3_HT_IRQS which has unmet direct dependencies (PPC_MAPLE) Fix that by removing the dependency on PPC_MAPLE.
