I had to update this patch because more warnings have just appeared.

You cannot print a u64 with %l or %ll.  You do not know what type the
architecture is using.  It must be cast to a type which matches the printf
control string - unsigned long long.

The patch also fixes some overly-long strings.  Please try to keep the code
looking neat in an 80-col window.

The Chelsio driver does not return the correct values from
the transmit routine. It works because the values don't conflict,
but it is using the wrong defines. And -ENOMEM is not a legal return
value.

Since t1_sge_tx is only called in one place, making it static
allows compiler to be potentially inline it.

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 281ab031.

The doubled semi-colon ends up being an empty instruction, and the
variable declaration thus ends up being in the middle of "code".

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

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.

I see why the problem exists only on SN. SN uses a different hardware
mechanism to purge TLB entries across nodes.

It looks like there is a bug in the SN TLB flushing code. During context switch,
kernel threads inherit the mm of the task that was previously running on the
cpu. This confuses the code in sn2_global_tlb_purge().

The result is a missed TLB purge for the task that owns the "borrowed" mm.

(I hit the problem running heavy stress where kswapd was purging code pages of
a user task that woke kswapd. The user task took a SIGILL fault trying to
execute code in the page that had been ripped out from underneath it).
