2009-11-17fcntl: rename F_OWNER_GID to F_OWNER_PGRPPeter Zijlstra
This is for consistency with various ioctl() operations that include the suffix "PGRP" in their names, and also for consistency with PRIO_PGRP, used with setpriority() and getpriority(). Also, using PGRP instead of GID avoids confusion with the common abbreviation of "group ID". I'm fine with anything that makes it more consistent, and if PGRP is what is the predominant abbreviation then I see no need to further confuse matters by adding a third one.

2009-11-17mm: allow memory hotplug and hibernation in the same kernelAndi Kleen
Allow memory hotplug and hibernation in the same kernel Memory hotplug and hibernation were exclusive in Kconfig. This is obviously a problem for distribution kernels who want to support both in the same image. After some discussions with Rafael and others the only problem is with parallel memory hotadd or removal while a hibernation operation is in process. It was also working for s390 before. This patch removes the Kconfig level exclusion, and simply makes the memory add / remove functions grab the pm_mutex to exclude against hibernation. Fixes a regression - old kernels didn't exclude memory hotadd and hibernation.

2009-11-17workqueue: fix race condition in schedule_on_each_cpu()Tejun Heo
Commit 65a64464349883891e21e74af16c05d6e1eeb4e9 ("HWPOISON: Allow schedule_on_each_cpu() from keventd") which allows schedule_on_each_cpu() to be called from keventd added a race condition. schedule_on_each_cpu() may race with cpu hotplug and end up executing the function twice on a cpu. Fix it by moving direct execution into the section protected with get/put_online_cpus(). While at it, update code such that direct execution is done after works have been scheduled for all other cpus and drop unnecessary cpu != orig test from flush loop.

Add D-Link DWM-162-U5 device id 1e0e:ce16 into option driver. The device has 4 interfaces, of which 1 is handled by storage and the other 3 by option driver.

2009-11-17USB: usbmon: fix bug in mon_buff_area_shrinkAlan Stern
This patch (as1299b) fixes a bug in an error-handling path of usbmon's binary interface. The storage area for URB data is divided into fixed-size blocks. If an URB's data can't be copied, the area reserved for it should be decreased to the size of the truncated information (rounded up to a block boundary). Rounding up the amount to be removed and subtracting it from the reserved size is definitely the wrong thing to do. Also, when the data for an isochronous URB can't be copied, we can still copy the isoc packet descriptors. In fact the current code does copy the descriptors, but then sets the capture length to 0 so they remain inaccessible. The capture length should be reduced to the length of the descriptors, not set to 0.

2009-11-17USB: xhci: Fix TRB physical to virtual address translation.Sarah Sharp
The trb_in_td() function in the xHCI driver is supposed to translate a physical transfer buffer request (TRB) into a virtual pointer to the ring segment that TRB is in. Unfortunately, a mistake in this function may cause endless loops as the driver searches through the linked list of ring segments over and over again. Fix a couple bugs that may lead to loops or bad output: 1. Bail out if we get a NULL pointer when translating the segment's private structure and the starting DMA address of the segment chunk. If this happens, we've been handed a starting TRB pointer from a different ring. 2. Make sure the function works when there's multiple segments in the ring. In the while loop to search through the ring segments, use the current segment variable (cur_seg), rather than the starting segment variable (start_seg) that is passed in. 3. Stop searching the ring if we've run through all the segments in the ring.

Hence reconnecting the device results in creation of /dev/ttyACM(x+1). The same happens when the system is hibernated during a PPP connection. This memory leak is due to the fact that when the tty is hung up, tty_port_close_start() returns always zero, and acm_tty_close() never reaches the point where acm_tty_unregister() is called.

Fix this not by reverting but by adding the proper dtr_rts and carrier_raised methods.

2009-11-17xfs: copy li_lsn before dropping AIL lockNathaniel W. Turner
Access to log items on the AIL is generally protected by m_ail_lock; this is particularly needed when we're getting or setting the 64-bit li_lsn on a 32-bit platform. This patch fixes a couple places where we were accessing the log item after dropping the AIL lock on 32-bit machines. This can result in a partially-zeroed log->l_tail_lsn if xfs_trans_ail_delete is racing with xfs_trans_ail_update, and in at least some cases, this can leave the l_tail_lsn with a zero cycle number, which means xlog_space_left will think the log is full (unless CONFIG_XFS_DEBUG is set, in which case we'll trip an ASSERT), leading to processes stuck forever in xlog_grant_log_space.

Hi, I was hit by a bug in linux 2.6.31 when XFS is not able to recover the log after a crash if fs was mounted with quotas. Gory details in XFS bugzilla: http://oss.sgi.com/bugzilla/show_bug.cgi?id=855. It looks like wrong struct is used in buffer length check, and the following patch should fix the problem. xfs_dqblk_t has a size of 104+32 bytes, while xfs_disk_dquot_t is 104 bytes long, and this is exactly what I see in system logs - "XFS: dquot too small (104) in xlog_recover_do_dquot_trans."

2009-11-16at91: at91sam9g20ek modify dual slot evaluation kitNicolas Ferre
at91sam9g20ek rev. C and onwards embed two SD/MMC slots. This patch modify the previous dual slot board definition to match the official rev. C board. It also allows the use of at91_mci SD/MMC driver in addition to the atmel-mci one. Some pins have been re-affected from leds or Ethernet phy IRQ to the SD/MMC slot A. This lead to a modification of those definitions. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Andrew Victor <linux@maxim.org.za>
2009-11-16cifs: clear server inode number flag while autodisablingSuresh Jayaraman
Fix the commit ec06aedd44 that intended to turn off querying for server inode numbers when server doesn't consistently support inode numbers. Presumably the commit didn't actually clear the CIFS_MOUNT_SERVER_INUM flag, perhaps a typo.

2009-11-16leds-gpio: fix possible crash on OF device unbindingDmitry Eremin-Solenikov
If there are leds present in the OF tree, but the GPIOs for (some) of them are unavailable, led_data doesn't get populated with correct devices. Then, on device unbinding, one can crash the kernel. Workaround this by setting led->gpio to invalid value early. Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>
2009-11-16backlight: Fix backlight limiting on spitz/corgi devicesPavel Machek
On spitz (& similar) machines, if battery is running low, backlight needs to be limited to lower step. Unfortunately, current code uses &= for limiting, turning backlight off completely for some backlight settings. Fix that.
