Remove a BUG_ON for when interrupts are disabled during an MMC request.
During boot, interrupts can be disabled when a request is made, causing
this bug to be triggered. In reality, there's no reason this should halt
the kernel, as the driver has proved reliable in spite of disabled
interrupts, and additionally, there's nothing in this code that would
require interrupts to be enabled.
The only setup I've managed to make it trigger on is on the HTC Herald
during bootup when the driver is built into the kernel (mostly because
that's all I have). I believe it's related to the fact that on bootup I
get many timeout errors on "CMD5" while initializing the card. Each CMD5
timeout triggers that bug (I changed it to a WARN_ON to get it to boot in)
due to the fact that part of the timeout code involves sending the request
again. With interrupts turned off, that BUG would be triggered.

Greg Thelen reported recent Johannes's stack diet patch makes kernel hang.
His test is following.
mount -t cgroup none /cgroups -o memory
mkdir /cgroups/cg1
echo $$ > /cgroups/cg1/tasks
dd bs=1024 count=1024 if=/dev/null of=/data/foo
echo $$ > /cgroups/tasks
echo 1 > /cgroups/cg1/memory.force_empty
Actually, This OOM hard to try logic have been corrupted since following
two years old patch.
commit a41f24ea9fd6169b147c53c2392e2887cc1d9247
Author: Nishanth Aravamudan <nacc@us.ibm.com>
Date: Tue Apr 29 00:58:25 2008 -0700
page allocator: smarter retry of costly-order allocations
Original intention was "return success if the system have shrinkable zones
though priority==0 reclaim was failure". But the above patch changed to
"return nr_reclaimed if .....". Oh, That forgot nr_reclaimed may be 0 if
priority==0 reclaim failure.
And Johannes's patch 0aeb2339e54e ("vmscan: remove all_unreclaimable scan
control") made it more corrupt. Originally, priority==0 reclaim failure
on memcg return 0, but this patch changed to return 1. It totally
confused memcg.
This patch fixes it completely.

The commit 80b5184cc537718122e036afe7e62d202b70d077 ("kernel/: convert cpu
notifier to return encapsulate errno value") changed the return value of
cpu notifier callbacks.
Those callbacks don't return NOTIFY_BAD on failures anymore. But there
are a few callbacks which are called directly at init time and checking
the return value.
I forgot to change BUG_ON checking by the direct callers in the commit.

Child groups should have a greater depth than their parents. Prior to
this change, the parent would incorrectly report zero memory usage for
child cgroups when use_hierarchy is enabled.
test script:
mount -t cgroup none /cgroups -o memory
cd /cgroups
mkdir cg1
echo 1 > cg1/memory.use_hierarchy
mkdir cg1/cg11
echo $$ > cg1/cg11/tasks
dd if=/dev/zero of=/tmp/foo bs=1M count=1
echo
echo CHILD
grep cache cg1/cg11/memory.stat
echo
echo PARENT
grep cache cg1/memory.stat
echo $$ > tasks
rmdir cg1/cg11 cg1
cd /
umount /cgroups
Using fae9c79, a recent patch that changed alloc_css_id() depth computation,
the parent incorrectly reports zero usage:
root@ubuntu:~# ./test
1+0 records in
1+0 records out
1048576 bytes (1.0 MB) copied, 0.0151844 s, 69.1 MB/s
CHILD
cache 1048576
total_cache 1048576
PARENT
cache 0
total_cache 0
With this patch, the parent correctly includes child usage:
root@ubuntu:~# ./test
1+0 records in
1+0 records out
1048576 bytes (1.0 MB) copied, 0.0136827 s, 76.6 MB/s

Commit f601441916d1e19291d0b4f044b4a7551e2924d0 ("imxfb: add support for
i.MX25:) has inserted the symbol HAVE_FB_IMX, which does not depend on FB
after the menuconfig FB. This breaks the menu, presenting most of the
drivers outside of it, when using menuconfig.
Moving the symbol to the start of the file, just like HAVE_FB_ATMEL, fixes
the problem without breaking it for iMX25 configurations (tested with
ARCH=arm, no build).

of u_long
task_struct->pesonality is "unsigned int", but sys_personality() paths use
"unsigned long pesonality". This means that every assignment or
comparison is not right. In particular, if this argument does not fit
into "unsigned int" __set_personality() changes the caller's personality
and then sys_personality() returns -EINVAL.
Turn this argument into "unsigned int" and avoid overflows. Obviously,
this is the user-visible change, we just ignore the upper bits. But this
can't break the sane application.
There is another thing which can confuse the poorly written applications.
User-space thinks that this syscall returns int, not long. This means
that the returned value can be negative and look like the error code. But
note that libc won't be confused and thus errno won't be set, and with
this patch the user-space can never get -1 unless sys_personality() really
fails. And, most importantly, the negative RET != -1 is only possible if
that app previously called personality(RET).

Although the fix provided is correct, it's been suggested to avoid the
underlying race in the same way as it is currently done in filesystems
like NFS, for maintainability.
A following patch "fb_defio: redo fix for non-dirty ptes" will provide
such an alternate fix.

The stack and data have different alignment requirements, so don't force
them to wear the same shoe. Increase the data alignment to match that
which the elf2flt linker script has always been using: 0x20 bytes. Not
only does this bring the kernel loader in line with the toolchain, but it
also fixes a swath of gcc tests which try to force larger alignment values
but randomly fail when the FLAT loader fails to deliver.

A new buffer for a packet is created when a icmp packet is received.
This happens in a context with disabled irq. Thus we are not allowed to
sleep or call function which might sleep. kmalloc must be called with
GFP_ATOMIC instead of GFP_KERNEL to ensure that it does not sleep.

Free_netdev is registered as destructor in interface_setup for every
soft_device. This destructor is automatically called from
unregister_netdev and we must not call it again for the freed
net_device.

We must call unregister_netdev when we couldn't initialise the
batman-adv module and the soft_device was registered. There are two
version of the function which we can use:
* unregister_netdevice - removes device
* unregister_netdev - takes rtnl semaphore and remove device
We don't hold the semaphore in an error situation. So we must use
unregister_netdev.

On module shutdown batman-adv would purge the internal packet
queue by sending all remaining packets which could confuse
other nodes. Now, the packets are silently discarded.

Qualcomm development of the MSM SOC framebuffer driver has
diverged significantly from the driver used by Android. This
is a snapshot of our current driver, in all it's agony. We are
putting this in staging to help with the process of converging
the two drivers.
At this point, the driver has been tested only in dumb
framebuffer mode.

Both drivers support directly or indirectly multiple bus types,
hence both are listed independent of bus types.

Don't allow COMEDI_BUFINFO ioctl if some other file object has locked
the subdevice or has an active command. If there is no active command,
just report back the last buffer position.

When the COMEDI_BUFINFO ioctl is used on a subdevice without
asynchronous streaming command support, set 'bytes_read = 0' and
'bytes_written = 0' in the buffer info returned back to the user.

For write(), any data copied to the data buffer after the previously
set up streaming acquisition command has finished won't be used, but a
non-empty write() does not currently return 0 (or -EPIPE on error) after
the command has finished until the data buffer has been filled up.
Change this behavior to return 0 (or -EPIPE) any time after the command
has finished, without bothering to fill up the buffer with more useless
data.

The internal state of an 82C54 counter timer chip will get messed up if

simultaneously. Protect the register access sequences with a spin lock.

Add support for the Advantech PCI-1735U card, including support for a
counter subdevice (based on an 82C54 counter timer chip).
The counter subdevice needs more testing, as the only person I know who
tried it couldn't get it to work!
