We should set this before calling agp_add_bridge() so that it's done

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.

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.

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.

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.

I have the same problem with cdc-acm (I'm using a Samsung SGH-U900): when I
unplug it from the USB port during a PPP connection, the ppp daemon gets the
hangup correctly (and closes the device), but the struct acm corresponding to
the device disconnected is not freed. 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.
Here is a fix for this.

9a68e39d4a701fb3be03cae9b462408664ebd205 broke carrier handling so that a
cp210x setup which needed the carrier lines set up (non CLOCAL) which did
not make a call which set the termios bits left the lines down even if
CLOCAL was not asserted.
Fix this not by reverting but by adding the proper dtr_rts and
carrier_raised methods. This both sets the modem lines properly and also
implements the correct blocking semantics for the port as required by
POSIX.

The tty_port code inherited a bug common to various drivers it was based
upon. If the tty is opened O_NONBLOCK we do not wait for the carrier to be
raised but we must still raise our modem lines if appropriate.
(There is a second question here about whether we should do so if CLOCAL is
set but that can wait)

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.
Thanks to Adrian VanderSpek for first spotting the race potential and to
Dave Chinner for debug assistance.

Hi,

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

When we've merged skb's with page frags, and subsequently receive
a trailer skb (< MSS) that is not completely non-linear (this can
occur on Intel NICs if the packet size falls below the threshold),
GRO ends up producing an illegal GSO skb with a frag_list.
This is harmless unless the skb is then forwarded through an

will BUG.
This patch detects this case in GRO and avoids merging the

before reading the PPP protocol, thus causing PPP to report seemingly
random 'unsupported protocols' and eventually trigger BUG_ON(skb->len <
skb->data_len) in skb_pull_rcsum() when receiving multilink protocol in
non-linear skbs.
ppp_receive_nonmp_frame() does not call pskb_may_pull() before reading the
protocol number. For the non-mp receive path this is not a problem, as
this check is done in ppp_receive_frame(). For the mp receive path,
ppp_mp_reconstruct() usually copies the data into a new linear skb.
However, in the case where the frame is made up of a single mp fragment,
the mp header is pulled and the existing skb used. This skb was then
passed to ppp_receive_nonmp_frame() without checking if the encapsulated
protocol header could safely be read.

After commmit 4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff EEH breaks
after the second error, since it calls pci_restore_state()
but it returns 0, since pci->state_saved is false.
So, this patch just call pci_save_state() after pci_restore_state().

Commit b7802c5c1ea ("Input: psmouse - use boolean type") caused the
synaptics_hardware variable to be completely useless, as it is
constantly set to 'true' throughout the whole psmouse_extensions().
This was caused by the following hunk in the commit in question
- int synaptics_hardware = 0;
+ bool synaptics_hardware = true;
which is wrong and causes driver to issue extra reset when falling
back to bare PS/2 protocol.

Interpretation of 'row' and 'col' got reversed in matrix keymap
framework. Also last element '0', present in keymap array, is no
more needed.
Correcting zoom2 keyboard keymap accordingly.

hx4700 touchscreen events were being dropped in ads7846_rx() because their
pressure values consistently exceeded the platform maximum of 512; a sample
of 256 pressure values were in the range 531 to 815. Doubling the platform
maximum to 1024 allows hx4700 touchscreen events to pass the test.

This will fix some small issues with the COH 901 331 RTC driver:
- Interrupt is disabled after alarm so that we don't fire
multiple interrupts.
- We return 0 from the coh901331_alarm_irq_enable() ridding
a compile warning.
- We alter the name in the U300 device registry to match that
of the driver so they sucessfully resolve.

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.

Fix the commit ec06aedd44 that intended to turn off querying for server inode

the commit didn't actually clear the CIFS_MOUNT_SERVER_INUM flag, perhaps a
