2011-08-01rtlwifi: Fix kernel oops on ARM SOCLarry Finger
This driver uses information from the self member of the pci_bus struct to get information regarding the bridge to which the PCIe device is attached. Unfortunately, this member is not established on all architectures, which leads to a kernel oops. Skipping the entire block that uses the self member to determine the bridge vendor will only affect RTL8192DE devices as that driver sets the ASPM support flag differently when the bridge vendor is Intel. If the self member is available, there is no functional change. This patch fixes Bugzilla No. 40212.

2011-08-01ath9k: skip ->config_pci_powersave() if PCIe port has ASPM disabledStanislaw Gruszka
We receive many bug reports about system hang during suspend/resume when ath9k driver is in use. Adrian Chadd remarked that this problem happens on systems that have ASPM disabled. To do not hit the bug, skip doing ->config_pci_powersave magic if PCIe downstream port device, which ath9k device is connected to, has ASPM disabled. Bug was introduced by: commit 53bc7aa08b48e5cd745f986731cc7dc24eef2a9f Author: Vivek Natarajan <vnatarajan@atheros.com> Date: Mon Apr 5 14:48:04 2010 +0530 ath9k: Add support for newer AR9285 chipsets.

2011-08-01xhci: Don't submit commands or URBs to halted hosts.Sarah Sharp
Commit fccf4e86200b8f5edd9a65da26f150e32ba79808 "USB: Free bandwidth when usb_disable_device is called" caused a bit of an issue when the xHCI host controller driver is unloaded. It changed the USB core to remove all endpoints when a USB device is disabled. When the driver is unloaded, it will remove the SuperSpeed split root hub, which will disable all devices under that roothub and then halt the host controller. When the second High Speed split roothub is removed, the USB core will attempt to disable the endpoints, which will submit a Configure Endpoint command to a halted host controller. The command will eventually time out, but it makes the xHCI driver unload take *minutes* if there are a couple of USB 1.1/2.0 devices attached. We must halt the host controller when the SuperSpeed roothub is removed, because we can't allow any interrupts from things like port status changes. Make several different functions not submit commands or URBs to the host controller when the host is halted, by adding a check in xhci_check_args(). xhci_check_args() is used by these functions: xhci.c-int xhci_urb_enqueue() xhci.c-int xhci_drop_endpoint() xhci.c-int xhci_add_endpoint() xhci.c-int xhci_check_bandwidth() xhci.c-void xhci_reset_bandwidth() xhci.c-static int xhci_check_streams_endpoint() xhci.c-int xhci_discover_or_reset_device() It's also used by xhci_free_dev(). However, we have to take special care in that case, because we want the device memory to be freed if the host controller is halted. This patch should be backported to the 2.6.39 and 3.0 kernel.

2011-08-01VFS: Reorganise shrink_dcache_for_umount_subtree() after demise of dcache_lockDavid Howells
Reorganise shrink_dcache_for_umount_subtree() in light of the demise of dcache_lock. Without that dcache_lock, there is no need for the batching of removal of dentries from the system under it (we wanted to make intensive use of the locked data whilst we held it, but didn't want to hold it for long at a time). This works, provided the preceding patch is correct in its removal of locking on dentry->d_lock on the basis that no one should be locking these dentries any more as the whole superblock is defunct. With this patch, the calls to dentry_lru_del() and __d_shrink() are placed at the point where each dentry is detached handled. It is possible that, as an alternative, the batching should still be done - but only for dentry_lru_del() of all a dentry's children in one go. In such a case, the batching would be done under dcache_lru_lock. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2011-08-01VFS: Remove dentry->d_lock locking from shrink_dcache_for_umount_subtree()David Howells
Locks of the dcache_lock were replaced by locks of dentry->d_lock in commits such as: 2304450783dfde7b0b94ae234edd0dbffa865073 2fd6b7f50797f2e993eea59e0a0b8c6399c811dc as part of the RCU-based pathwalk changes, despite the fact that the caller (shrink_dcache_for_umount()) notes in the banner comment the reasons that d_lock is not necessary in these functions: /* * destroy the dentries attached to a superblock on unmounting * - we don't need to use dentry->d_lock because: * - the superblock is detached from all mountings and open files, so the * dentry trees will not be rearranged by the VFS * - s_umount is write-locked, so the memory pressure shrinker will ignore * any dentries belonging to this superblock that it comes across * - the filesystem itself is no longer permitted to rearrange the dentries * in this superblock */ So remove these locks. If the locks are actually necessary, then this banner comment should be altered instead. The hash table chains are protected by 1-bit locks in the hash table heads, so those shouldn't be a problem. Note that to make this work, __d_drop() has to be split so that the RCUwalk barrier can be avoided. This causes problems otherwise as it has an assertion that dentry->d_lock is locked - but there is no need for that as no one else can be trying to access this dentry, except to step over it (and that should be handled by d_free(), I think).

2011-08-01block: initialise bd_super in bdget()Lachlan McIlroy
bd_super is currently reset to NULL in kill_block_super() so we rely on previous users of the block_device object to initialise this value for the next user. This quirk was exposed on RHEL5 when a third party filesystem did not always use kill_block_super() and therefore bd_super wasn't being reset when a block_device object was recycled within the cache. This may not be a problem upstream but makes sense to be defensive.
