      POWERPC: Make alignment exception always check exception table · 371899a7
      Benjamin Herrenschmidt authored 
      The alignment exception used to only check the exception table for
-EFAULT, not for other errors. That opens an oops window if we can
coerce the kernel into getting an alignment exception for other reasons
in what would normally be a user-protected accessor, which can be done
via some of the futex ops. This fixes it by always checking the
exception tables.

      Artur Skawina authored 
      this patch is required to get a SIS964 based motherboard ethernet working
(FSC D1875) (picking the #1 transceiver, instead of the last one, in case
no known ones were found might be a better default, and would have worked
in this case too)

      Old IDE, fix SATA detection for cabling · c61120c3

      This patch is identical to that introduced in
1a1276e7 to the Linus' 2.6 development tree
by Alan Cox.

'This is based on the proposed patches flying around but also checks that
the device in question is new enough to have word 93 rather thanb blindly
assuming word 93 == 0 means SATA (see ATA-5, ATA-7)' -- Alan Cox

Required for my SATA drive on an Asus Pundit-R to operate above 33MBps.

      Fix BeFS slab corruption · 2c8e2c9f
      Diego Calleja authored 
      In bugzilla #6941, Jens Kilian reported:

"The function befs_utf2nls (in fs/befs/linuxvfs.c) writes a 0 byte past the
end of a block of memory allocated via kmalloc(), leading to memory
corruption.  This happens only for filenames which are pure ASCII and a
multiple of 4 bytes in length.  [...]

Without DEBUG_SLAB, this leads to further corruption and hard lockups; I
believe this is the bug which has made kernels later than 2.6.8 unusable
for me.  (This must be due to changes in memory management, the bug has
been in the BeFS driver since the time it was introduced (AFAICT).)

Steps to reproduce:
Create a directory (in BeOS, naturally :-) with files named, e.g.,
"1", "22", "333", "4444", ...  Mount it in Linux and do an "ls" or "find""

This patch implements the suggested fix. Credits to Jens Kilian for
debugging the problem and finding the right fix.

      V4L/DVB: Saa7134: rename dmasound_{init,exit} · facabd61
      Adrian Bunk authored 
      Two different exports with the same name are not a good idea:

$ grep -r EXPORT_SYMBOL\(dmasound_init\) *

sound/oss/dmasound/dmasound_core.c:EXPORT_SYMBOL(dmasound_init);

This patch renames the saa7134 dmasound_{init,exit} to
saa7134_dmasound_{init,exit}.

      Fix timer race in dst GC code · 9e9c7147
      Dmitry Mishin authored 
      Replace add_timer() by mod_timer() in dst_run_gc
in order to avoid BUG message.

   CPU1                            CPU2
dst_run_gc()  entered           dst_run_gc() entered
spin_lock(&dst_lock)                   .....
del_timer(&dst_gc_timer)         fail to get lock
   ....                         mod_timer() <--- puts
                                             timer back
                                             to the list
add_timer(&dst_gc_timer) <--- BUG because timer is in list already.

Found during OpenVZ internal testing.

At first we thought that it is OpenVZ specific as we
added dst_run_gc(0) call in dst_dev_event(),
but as Alexey pointed to me it is possible to trigger
this condition in mainstream kernel.

F.e. timer has fired on CPU2, but the handler was preeempted
by an irq before dst_lock is tried.
Meanwhile, someone on CPU1 adds an entry to gc list and
starts the timer.
If CPU2 was preempted long enough, this timer can expire
simultaneously with resuming timer handler on CPU1, arriving
exactly to the situation described.

      security/seclvl.c: fix time wrap (CVE-2005-4352) · e6169b53
      Adrian Bunk authored 
      initlvl=2 in seclvl gives the guarantee
"Cannot decrement the system time".

But it was possible to set the time to the maximum unixtime value
(19 Jan 2038) resulting in a wrap to the minimum value.

This patch fixes this by disallowing setting the time to any date
after 2030 with initlvl=2.

      Fix longstanding load balancing bug in the scheduler · ef147950
      Christoph Lameter authored 
      The scheduler will stop load balancing if the most busy processor contains
processes pinned via processor affinity.

The scheduler currently only does one search for busiest cpu.  If it cannot
pull any tasks away from the busiest cpu because they were pinned then the
scheduler goes into a corner and sulks leaving the idle processors idle.

F.e.  If you have processor 0 busy running four tasks pinned via taskset,
there are none on processor 1 and one just started two processes on
processor 2 then the scheduler will not move one of the two processes away
from processor 2.

This patch fixes that issue by forcing the scheduler to come out of its
corner and retrying the load balancing by considering other processors for
load balancing.

This patch was originally developed by John Hawkes and discussed at

    http://marc.theaimsgroup.com/?l=linux-kernel&m=113901368523205&w=2.

I have removed extraneous material and gone back to equipping struct rq
with the cpu the queue is associated with since this makes the patch much
easier and it is likely that others in the future will have the same
difficulty of figuring out which processor owns which runqueue.

The overhead added through these patches is a single word on the stack if
the kernel is configured to support 32 cpus or less (32 bit).  For 32 bit
environments the maximum number of cpus that can be configued is 255 which
would result in the use of 32 bytes additional on the stack.  On IA64 up to
1k cpus can be configured which will result in the use of 128 additional
bytes on the stack.  The maximum additional cache footprint is one
cacheline.  Typically memory use will be much less than a cacheline and the
additional cpumask will be placed on the stack in a cacheline that already
contains other local variable.
