85fe068123 [ARM] 3648/1: Update struct ucontext layout for coprocessor registers
Patch from Daniel Jacobowitz

In order for userspace to find saved coprocessor registers, move them from
struct rt_sigframe into struct ucontext.  Also allow space for glibc's
sigset_t, so that userspace and kernelspace can use the same ucontext
layout.  Define the magic numbers for iWMMXt in the header file for easier
reference.  Include the size of the coprocessor data in the magic numbers.

Also define magic numbers and layout for VFP, not yet saved.

ca195cfec9 [ARM] Add identifying number for non-rt sigframe
GDB couldn't reliably tell the difference between the old and new
non-rt sigframes, so provide it with a number at the beginning which
will never appear in the old sigframe, and hence provide gdb with a
reliable way to tell the two apart.

caaa5f9f0a [PATCH] cfq-iosched: many performance fixes
This is a collection of patches that greatly improve CFQ performance
in some circumstances.

- Change the idling logic to only kick in after a request is done and we
  are deciding what to do. Before the idling included the request service
  time, so it was hard to adjust. Now it's true think/idle time.

- Take advantage of TCQ/NCQ/queueing for seeky sync workloads, but keep
  it in control for sync and sequential (or close to) workloads.

- Expire queues immediately and move on to other busy queues, if we are
  not going to idle after the current one finishes.

- Don't rearm idle timer if there are no busy queues. Just leave the
  system idle.

35e6077cb1 [PATCH] cfq-iosched: correctly set ioprio on both targets
Patch originally from Vasily Tarasov <vtaras@sw.ru>

If you set io-priority of process 1 using sys_ioprio_set system call by
another process 2 (like ionice do), then cfq_init_prio_data() function
sets priority of process 2 (current) on queue of process 1 and clears
the flag, that designates change of ioprio.  So the process  1 will work
like with priority of process 2.

I propose not to call cfq_init_prio_data() on io-priority change, but
only mark queue as queue with changed prority.  Every time when new
request comes cfq-scheduler checks for this flag and atomaticaly changes
priority of queue to new value.

b31dc66a54 [PATCH] Kill PF_SYNCWRITE flag
A process flag to indicate whether we are doing sync io is incredibly
ugly. It also causes performance problems when one does a lot of async
io and then proceeds to sync it. Part of the io will go out as async,
and the other part as sync. This causes a disconnect between the
previously submitted io and the synced io. For io schedulers such as CFQ,
this will cause us lost merges and suboptimal behaviour in scheduling.

Remove PF_SYNCWRITE completely from the fsync/msync paths, and let
the O_DIRECT path just directly indicate that the writes are sync
by using WRITE_SYNC instead.

eefe85ee35 [PATCH] drivers/block/loop.c: don't return garbage if LOOP_SET_STATUS not called
While writing a version of losetup, I ran into the problem that the loop
device was returning total garbage.

It turns out the problem was that this losetup was only issuing the
LOOP_SET_FD ioctl and not issuing a subsequent LOOP_SET_STATUS ioctl.  This
losetup didn't have any special status to set, so it left out the call.

The deeper cause is that loop_set_fd sets the transfer function to NULL,
which causes no transfer to happen lo_do_transfer.

This patch fixes the problem by setting transfer to transfer_none in
loop_set_fd.

98bd34eaf1 [PATCH] make kernel warn about incorrectly sized partitions
Sometimes partitions claim to be larger than the reported capacity of a
disk device.  This patch makes the kernel warn about those partitions.

We still permit these patitions to be used.  Quoting Andries Brouwer
<Andries.Brouwer@cwi.nl>:

 Case 1: The kernel is mistaken about the size of the disk.  (There are
 commands to clip a disk to a certain capacity, there are jumpers to tell a
 disk that it should report a certain capacity etc.  Usually this is because
 of BIOS bugs.  In bad cases the machine will crash in the BIOS and hence fail
 to boot if the disk reports full capacity.) In such cases actually accessing
 the blocks of the partition may work fine, or may work fine after running an
 unclip utility.  I wrote "setmax" some years ago precisely for this reason.

 Case 2: There was a messy partition table (maybe just a rounding error) but
 the actual filesystem on the partition is contained in the physical disk.
 Now using the filesystem goes without problem.

 Case 3: Both partition and filesystem extend beyond the end of the disk.  In
 forensic or debugging situations one often uses a copy of the start of a
 disk.  Now access beyond the end gives an expected I/O error.
