I had thought that keeping the reported tail level clearly different
from the module name was a good idea, but I've changed my mind.
'raid5' is better and probably less confusing than 'RAID-5'.

Patch from Nicolas Pitre
Strictly speaking, the NPTL kernel helpers are required for pre ARMv6
only. They are available on ARMv6+ as well for obvious compatibility
reasons. However there are cases where extra memory barriers are needed
when using an SMP ARMv6 machine but not on pre-ARMv6.
This patch adds a memory barrier kernel helper that glibc can use as
needed for pre-ARMv6 binaries to be forward compatible with an SMP
kernel on ARMv6, as well as the necessary dmb instructions to the
cmpxchg helper.

The route expiration time is stored in rt6i_expires in jiffies.
The argument of rt6_route_add() for adding a route is not the
expiration time in jiffies nor in clock_t, but the lifetime
(or time left before expiration) in clock_t.
Because of the confusion, we sometimes saw several strange errors
(FAILs) in TAHI IPv6 Ready Logo Phase-2 Self Test.
The symptoms were analyzed by Mitsuru Chinen <CHINEN@jp.ibm.com>.

I reported a problem and gave hints to the solution, but nobody seemed
to react. So I prepared a patch against 2.6.14.4.
Tested on 2.6.14.4 with "ip monitor addr" and with the program
attached, while adding and removing IPv6 address. Both programs didn't
receive any messages. Tested 2.6.14.4 + this patch, and both programs
received add and remove messages.

Fix a typo which breaks radeon drm compilation with gcc 2.95.3.
The offending line was added back in 2.6.11-rc3, but was harmless
back then. A recent addition nearby changed it into a compilation
breaker: commit 281ab031a8c9e5b593142eb4ec59a87faae8676a.
The doubled semi-colon ends up being an empty instruction, and the
variable declaration thus ends up being in the middle of "code".

With Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>
UML skas0 stub has been miscompiling for many people (incidentally not
the authors), depending on the used GCC versions.
I think (and testing on some GCC versions shows) this patch avoids the
fundamental issue which is behind this, namely gcc using the stack when
we have just replaced it, behind gcc's back. The remapping and storage
of the return value is hidden in a blob of asm, hopefully giving gcc no
room for creativity.

The current UML build assumes that on x86-64 systems, /lib is a symlink
to /lib64, but in some distributions (like PLD and CentOS) they are
separate directories, so the 64 bit library loader isn't found. This
patch inserts /lib64 at the start of the rpath on x86-64 UML builds.

Miquel van Smoorenburg <miquels@cistron.nl> forwarded me this fix to
resolve a deadlock condition that occurs due to the API change in
2.6.13+ kernels dropping the host locking when entering the error
handling. They all end up calling adpt_i2o_post_wait(), which if you
call it unlocked, might return with host_lock locked anyway and that
causes a deadlock.

scsi_reap_target() was desgined to be called from any context.

Rather than providing more wrappers for 6-arg syscalls, arrange for
them to be supported as standard. This just means that we always
store the 6th argument on the stack, rather than in the wrappers.
This means we eliminate the wrappers for:

* sys_arm_fadvise64_64
* sys_mbind
* sys_ipc
