[ARM] 3044/1: Fix sparse warnings about incompatible pointer types for register defined in pxa-regs.h
Patch from Ian Campbell
The sparse warning initially surfaced in sound/arm/pxa2xx-ac97.c
because it was using u32 * variables to hold the unsigned long *
register addresses.
I submitted an ALSA patch for this http://thread.gmane.org/gmane.linux.alsa.devel/27804 issue and it was suggested that it might be preferable to change the register
definitions to use u32.
Most other subarches seem to use u32 for their register type, at least
the ones which use a __REG macro (like the PXA) do. Nico indicated in
the thread above that he wouldn't mind this patch.
Changing the type required fixes for opposite warnings in the pxa2xx usb
gadget code but that was the only new warning introduced on defconfig
or lubbock, mainstone and our own PXA255 boards.

tested on the IXP2350 NPU and I would like to get the support for
that chipset upstream one piece at a time. There are also other
Intel chipset ports in development that are waiting on this to go

The patch replaces the print formats for physical addresses with

[TCP]: Clear stale pred_flags when snd_wnd changes
This bug is responsible for causing the infamous "Treason uncloaked"
messages that's been popping up everywhere since the printk was added.
It has usually been blamed on foreign operating systems. However,
some of those reports implicate Linux as both systems are running
Linux or the TCP connection is going across the loopback interface.
In fact, there really is a bug in the Linux TCP header prediction code
that's been there since at least 2.1.8. This bug was tracked down with
help from Dale Blount.
The effect of this bug ranges from harmless "Treason uncloaked"
messages to hung/aborted TCP connections. The details of the bug
and fix is as follows.
When snd_wnd is updated, we only update pred_flags if
tcp_fast_path_check succeeds. When it fails (for example,
when our rcvbuf is used up), we will leave pred_flags with
an out-of-date snd_wnd value.
When the out-of-date pred_flags happens to match the next incoming
packet we will again hit the fast path and use the current snd_wnd
which will be wrong.
In the case of the treason messages, it just happens that the snd_wnd
cached in pred_flags is zero while tp->snd_wnd is non-zero. Therefore
when a zero-window packet comes in we incorrectly conclude that the
window is non-zero.
In fact if the peer continues to send us zero-window pure ACKs we
will continue making the same mistake. It's only when the peer
transmits a zero-window packet with data attached that we get a
chance to snap out of it. This is what triggers the treason
message at the next retransmit timeout.

[PATCH] Fix HFS+ to free up the space when a file is deleted.
fsck_hfs reveals lots of temporary files accumulating in the hidden

documentation these are files which are unlinked while in use. However,
there may be a bug in the Linux hfsplus implementation which causes this to
happen even when the files are not in use. It looks like the "opencnt"

will not reset '->firing' flag. In that case,
....
if (timer->it.cpu.firing) {

[PATCH] aio syscalls are not checked by lsm
Another case of missing call to security_file_permission: aio functions
(namely, io_submit) does not check credentials with security modules.
Below is the simple patch to the problem. It seems that it is enough to
check for rights at the request submission time.

Fix typos & trailing whitespace.
Add blank lines in a few places.

cardbus: limit IO windows to 256 bytes
That's what we've always historically done, and bigger windows seem to
confuse some cardbus bridges. Or something.
Alan reports that this makes the ThinkPad 600x series work properly
again: the 4kB IO window for some reason made IDE DMA not work, which
makes IDE painfully slow even if it works after DMA timeouts.

Posix timers: limit number of timers firing at once
Bursty timers aren't good for anybody, very much including latency for
other programs when we trigger lots of timers in interrupt context. So
set a random limit, after which we'll handle the rest on the next timer
tick.

[NEIGH] Fix timer leak in neigh_changeaddr
neigh_changeaddr attempts to delete neighbour timers without setting
nud_state. This doesn't work because the timer may have already fired
when we acquire the write lock in neigh_changeaddr. The result is that
the timer may keep firing for quite a while until the entry reaches
NEIGH_FAILED.
It should be setting the nud_state straight away so that if the timer
has already fired it can simply exit once we relinquish the lock.
In fact, this whole function is simply duplicating the logic in
neigh_ifdown which in turn is already doing the right thing when
it comes to deleting timers and setting nud_state.
So all we have to do is take that code out and put it into a common
function and make both neigh_changeaddr and neigh_ifdown call it.

[NEIGH] Fix add_timer race in neigh_add_timer
neigh_add_timer cannot use add_timer unconditionally. The reason is that
by the time it has obtained the write lock someone else (e.g., neigh_update)
could have already added a new timer.
So it should only use mod_timer and deal with its return value accordingly.
This bug would have led to rare neighbour cache entry leaks.

Stack traces are very helpful in determining the exact nature of a bug.
So let's print a stack trace when the timer is added twice.
