2010-07-20edac: mpc85xx: fix MPC85xx dependencyAnton Vorontsov1-1/+1
Since commit 5753c082f66eca5be81f6bda85c1718c5eea6ada ("powerpc/85xx: Kconfig cleanup"), there is no MPC85xx Kconfig symbol anymore, so the driver became non-selectable. This patch fixes the issue by switching to PPC_85xx symbol.

2010-07-20ipc/sem.c: bugfix for semop() not reporting successful operationManfred Spraul1-7/+39
The last change to improve the scalability moved the actual wake-up out of the section that is protected by spin_lock(sma->sem_perm.lock). This means that IN_WAKEUP can be in queue.status even when the spinlock is acquired by the current task. Thus the same loop that is performed when queue.status is read without the spinlock acquired must be performed when the spinlock is acquired.

2010-07-20tracing: Properly align linker defined symbolsSam Ravnborg1-0/+10
We define a number of symbols in the linker scipt like this: __start_syscalls_metadata = .; *(__syscalls_metadata) But we do not know the alignment of "." when we assign the __start_syscalls_metadata symbol. gcc started to uses bigger alignment for structs (32 bytes), so we saw situations where the linker due to alignment constraints increased the value of "." after the symbol assignment. This resulted in boot fails. Fix this by forcing a 32 byte alignment of "." before the assignment. This patch introduces the forced alignment for ftrace_events and syscalls_metadata. It may be required in more places.

2010-07-21drm/radeon/kms: fix shared ddc harderAlex Deucher1-14/+9
This fixes a regression caused by b2ea4aa67bfd084834edd070e0a4a47857d6db59 due to the way shared ddc with multiple digital connectors was handled. You generally have two cases where DDC lines are shared: - HDMI + VGA - HDMI + DVI-D HDMI + VGA is easy to deal with because you can check the EDID for the to see if the attached monitor is digital. A shared DDC line with two digital connectors is more complex. You can't use the hdmi bits in the EDID since they may not be there with DVI<->HDMI adapters. In this case all we can do is check the HPD pins to see which is connected as we have no way of knowing using the EDID.

My platform makes use of the null_legacy_pic choice and oopses when doing a shutdown as the shutdown code goes through all the registered sysdevs and calls their shutdown method which in my case poke on a non-existing i8259. Imho the i8259 specific sysdev should only be registered if the i8259 is actually there.

2010-07-20kbuild: Make the setlocalversion script POSIX-compliantMichał Górny1-3/+4
The 'source' builtin is a bash alias to the '.' (dot) builtin. While the former is supported only by bash, the latter is specified in POSIX and works fine with all POSIX-compliant shells I am aware of. The '$_' special parameter is specific to bash. It is partially supported in dash too but it always evaluates to the current script path (which causes the script to enter a loop recursively re-executing itself). This is why I have replaced the two occurences of '$_' with the explicit parameter. The 'local' builtin is another example of bash-specific code. Although it is supported by all POSIX-compliant shells I am aware of, it is not part of POSIX specification and thus the code should not rely on it assigning a specific value to the local variable. Moreover, the 'posh' shell has a limited version of 'local' builtin not supporting direct variable assignments. Thus, I have broken one of the 'local' declarations down into a (non-POSIX) 'local' declaration and a plain (POSIX-compliant) variable assignment.

2010-07-20xfs: track AGs with reclaimable inodes in per-ag radix treeDave Chinner2-7/+67
https://bugzilla.kernel.org/show_bug.cgi?id=16348 When the filesystem grows to a large number of allocation groups, the summing of recalimable inodes gets expensive. In many cases, most AGs won't have any reclaimable inodes and so we are wasting CPU time aggregating over these AGs. This is particularly important for the inode shrinker that gets called frequently under memory pressure. To avoid the overhead, track AGs with reclaimable inodes in the per-ag radix tree so that we can find all the AGs with reclaimable inodes via a simple gang tag lookup. This involves setting the tag when the first reclaimable inode is tracked in the AG, and removing the tag when the last reclaimable inode is removed from the tree. Then the summation process becomes a loop walking the radix tree summing AGs with the reclaim tag set. This significantly reduces the overhead of scanning - a 6400 AG filesystea now only uses about 25% of a cpu in kswapd while slab reclaim progresses instead of being permanently stuck at 100% CPU and making little progress. Clean filesystems filesystems will see no overhead and the overhead only increases linearly with the number of dirty AGs.

2010-07-20xfs: convert inode shrinker to per-filesystem contextsDave Chinner4-53/+15
Now the shrinker passes us a context, wire up a shrinker context per filesystem. This allows us to remove the global mount list and the locking problems that introduced. It also means that a shrinker call does not need to traverse clean filesystems before finding a filesystem with reclaimable inodes. This significantly reduces scanning overhead when lots of filesystems are present. Signed-off-by: Dave Chinner <[email protected]> Reviewed-by: Christoph Hellwig <[email protected]>

1. The BTRFS_IOC_CLONE and BTRFS_IOC_CLONE_RANGE ioctls should check whether the donor file is append-only before writing to it. 2. The BTRFS_IOC_CLONE_RANGE ioctl appears to have an integer overflow that allows a user to specify an out-of-bounds range to copy from the source file (if off + len wraps around). I haven't been able to successfully exploit this, but I'd imagine that a clever attacker could use this to read things he shouldn't. Even if it's not exploitable, it couldn't hurt to be safe.

The input handler for Type 2 Routing Header (mip6_rthdr_input()) checks if the CoA in the packet matches the CoA in the XFRM state. Current check is buggy: it compares the adddress in the Type 2 Routing Header, i.e. the HoA, against the expected CoA in the state. The comparison should be made against the address in the destination field of the IPv6 header.

2010-07-18drm/i915: add 'reclaimable' to i915 self-reclaimable page allocationsLinus Torvalds1-0/+1
The hibernate issues that got fixed in commit 985b823b9192 ("drm/i915: fix hibernation since i915 self-reclaim fixes") turn out to have been incomplete. Vefa Bicakci tested lots of hibernate cycles, and without the __GFP_RECLAIMABLE flag the system eventually fails to resume. With the flag added, Vefa can apparently hibernate forever (or until he gets bored running his automated scripts, whichever comes first). The reclaimable flag was there originally, and was one of the flags that were dropped (unintentionally) by commit 4bdadb978569 ("drm/i915: Selectively enable self-reclaim") that introduced all these problems, but I didn't want to just blindly add back all the flags in commit 985b823b9192, and it looked like __GFP_RECLAIM wasn't necessary. It clearly was. I still suspect that there is some subtle reason we're missing that causes the problems, but __GFP_RECLAIMABLE is certainly not wrong to use in this context, and is what the code historically used. And we have no idea what the causes the corruption without it. Reported-and-tested-by: M.

drivers/input/keyboard/Kconfig defines QT2160 while the corresponding Makefile expects CONFIG_KEYBOARD_QT2160 as all other keyboard drivers do. To keep this Makefile consistent rename the config-token from CONFIG_QT2160 to CONFIG_KEYBOARD_QT2160. The various defconfig files are left alone. Reported-by: Robert P. J.
