ac9af7cba9 [PATCH] ppc64: iommu vmerge fix
This fixes a bug in the PPC64 iommu vmerge code which results in the
potential for iommu_unmap_sg to go off unmapping more than it should.

This was found on a test system which resulted in PCI bus errors due to
PCI memory being unmapped while DMAs were still in progress.

c231c7db30 Revert unnecessary zlib_inflate/inftrees.c fix
It turns out that empty distance code tables are not an error, and that
a compressed block with only literals can validly have an empty table
and should not be flagged as a data error.

Some old versions of gzip had problems with this case, but it does not
affect the zlib code in the kernel.

c4f92dba97 [PATCH] nfsd to unlock kernel before exiting
The nfsd holds the big kernel lock upon exit, when it really shouldn't.
Not to mention that this breaks Ingo's RT patch. This is a trivial fix
to release the lock.

Ingo, this patch also works with your kernel, and stops the problem with
nfsd.

Note, there's a "goto out;" where "out:" is right above svc_exit_thread.
The point of the goto also holds the kernel_lock, so I don't see any
problem here in releasing it.

dd12f48d4e [PATCH] NPTL signal delivery deadlock fix
This bug is quite subtle and only happens in a very interesting
situation where a real-time threaded process is in the middle of a
coredump when someone whacks it with a SIGKILL.  However, this deadlock
leaves the system pretty hosed and you have to reboot to recover.

Not good for real-time priority-preemption applications like our
telephony application, with 90+ real-time (SCHED_FIFO and SCHED_RR)
processes, many of them multi-threaded, interacting with each other for
high volume call processing.

35d59efd10 [TCP]: Fix bug #5070: kernel BUG at net/ipv4/tcp_output.c:864
1) We send out a normal sized packet with TSO on to start off.
2) ICMP is received indicating a smaller MTU.
3) We send the current sk_send_head which needs to be fragmented
since it was created before the ICMP event.  The first fragment
is then sent out.

At this point the remaining fragment is allocated by tcp_fragment.
However, its size is padded to fit the L1 cache-line size therefore
creating tail-room up to 124 bytes long.

This fragment will also be sitting at sk_send_head.

4) tcp_sendmsg is called again and it stores data in the tail-room of
of the fragment.
5) tcp_push_one is called by tcp_sendmsg which then calls tso_fragment
since the packet as a whole exceeds the MTU.

At this point we have a packet that has data in the head area being
fed to tso_fragment which bombs out.

My take on this is that we shouldn't ever call tcp_fragment on a TSO
socket for a packet that is yet to be transmitted since this creates
a packet on sk_send_head that cannot be extended.

So here is a patch to change it so that tso_fragment is always used
in this case.

62ee914ef2 [ARM] 2850/1: Remove duplicate UART I/O mapping from s3c2410_iodesc
Patch from Dimitry Andric

This patch removes the initial UART I/O mapping from s3c2410_iodesc,
since the same mapping is already done in the function s3c24xx_init_io
in the file arch/arm/mach-s3c2410/cpu.c, through the s3c_iodesc array.
I'm not sure if duplicate mappings do any harm, but it's simply
redundant.  Also, in s3c2440.c the UART I/O mapping is NOT done.
Additionally, I put a comma behind the last mapping, to ease
copy/pasting stuff around, and make the style consistent with
s3c2440.c and other files.

2ad5649662 [PATCH] iSeries build with newer assemblers and compilers
Paulus suggested that we put xLparMap in its own .c file so that we can
generate a .s file to be included into head.S.  This doesn't get around
the problem of having it at a fixed address, but it makes it more
palatable.

It would be good if this could be included in 2.6.13 as it solves our
build problems with various versions of binutils and gcc.  In
particular, it allows us to build an iSeries kernel on Debian unstable
using their biarch compiler.

This has been built and booted on iSeries and built for pSeries and g5.

65e4308d25 [PATCH] NFS: Ensure we always update inode->i_mode when doing O_EXCL creates
When the client performs an exclusive create and opens the file for writing,
a Netapp filer will first create the file using the mode 01777. It does this
since an NFSv3/v4 exclusive create cannot immediately set the mode bits.
The 01777 mode then gets put into the inode->i_mode. After the file creation
is successful, we then do a setattr to change the mode to the correct value
(as per the NFS spec).

The problem is that nfs_refresh_inode() no longer updates inode->i_mode, so
the latter retains the 01777 mode. A bit later, the VFS notices this, and calls
remove_suid(). This of course now resets the file mode to inode->i_mode & 0777.
Hey presto, the file mode on the server is now magically changed to 0777. Duh...

3edea4833a [PATCH] intelfb/fbdev: Save info->flags in a local variable
Reported by: Pavel Kysilka (Bugzilla Bug 5059)

The intelfb driver does not keep resolution set with fbset after
switching to anot console and back.

Steps to reproduce:

  initial options: tty1,tty2 - 1024x768-60
  1) tty1 - fbset after booting (1024x768-60)
  2) tty1 - fbset 800x600-100
  tty1: 800x600-100
  3) swith to tty2, swith to tty1
  tty1: 1024x768-60 (the same resolution as default from kernel booting)

This bug is caused by intelfb unintentionally destroying info->flags in
set_par(). Therefore the flag, FBINFO_MISC_USEREVENT used to notify
fbcon of a mode change was cleared causing the above problem. This bug
though is not intelfb specific, as other drivers may also be affected.

The fix is to save info->flags in a local variable before calling any
of the driver hooks.  A more definitive fix (for post 2.6.13) is to
separate info->flags into one that is set by the driver and another that
is set by core fbdev/fbcon.
