[PATCH] fix for integer overflow in hd6457[02] driver code
The attached patch fixes an integer overflow in drivers for N2, C101,
PCI200SYN WAN cards (brv * port->settings.clock_rate overflowed at
requested clock rate of 8*1024*1024 bps, problem noted by Nagaraj Kanniah).

[PATCH] out-of-line locks / generic
This patch achieves out of line spinlocks by creating kernel/spinlock.c
and using the _raw_* inline locking functions.
Now, as much as this is supposed to be arch agnostic, there was still a
fair amount of rummaging about in archs, mostly for the cases where the
arch already has out of line locks and i wanted to avoid the extra call,
saving that extra call also makes lock profiling easier. PPC32/64 was
an example of such an arch and i have added the necessary profile_pc()
function as an example.
Size differences are with CONFIG_PREEMPT enabled since we wanted to
determine how much could be saved by moving that lot out of line too.
attached is a patch that polls the media setting for non GigE nForce
nics:
Without polling, media changes are not autodetected. This is fatal,
because the nic initialization is asynchroneous, thus "modprobe;ifup"
resulted in a dead network connection. The attached patch fixes that
problem.
It's a repost of a patch I sent around three weeks ago: you objected
that I rely on the nic irq instead of a software timer. I've documented
why this is ok.

[PATCH] fix sched_domains hotplug bootstrap ordering vs. cpu_online_map issue
cpu_online_map is not set up at the time of sched domain initialization
when hotplug cpu paths are used for SMP booting.
At this phase of bootstrapping, cpu_possible_map can be used by the
various architectures using cpu hotplugging for SMP bootstrap, but the
manipulations of cpu_online_map done on behalf of NUMA architectures,
done indirectly via node_to_cpumask(), can't, because cpu_online_map
starts depopulated and hasn't yet been populated.
On true NUMA architectures this is a distinct cpumask_t from
cpu_online_map and so the unpatched code works on NUMA; on non-NUMA
architectures the definition of node_to_cpumask() this way breaks and
would require an invasive sweeping of users of node_to_cpumask() to
change it to e.g. cpu_possible_map, as cpu_possible_map is not suitable
for use at runtime as a substitute for cpu_online_map.

[PATCH] Sort the CREDITS file properly (and add Jesper)
Many entries in the CREDITS file are not properly sorted in alphabetical
order, despite the note in the file that it is supposed to be sorted like
that.
This patch attempts to sort the CREDITS file properly. No existing entries
were changed, merely moved around in the file. There where a few tricky
names that I was unsure how to sort (names with characters such as ü, ö,
and people with many names where it was unclear to me what name to sort by
etc), in those cases I've usually left the names where they were unless it
was glaringly obvious they were in the wrong spot.
I've also taken the liberty to add my own name to the file - I have
contributed several tiny/small fixes/cleanups etc over the years.
bad_page() only prints out 8 hexadecimal digits of page->flags regardless
of sizeof(page_flags_t). This leads to confusing and/or incomplete bug
reports. The following patch uses a field width argument to replace the
hardcoded %08lx so that bad_page() may print the whole of page->flags.

Since in-kernel colorspace conversion is not allowed, this patch disables it
in the CPiA video camera driver by default. Users should fix the applications
in case they don't work without conversion reenabled by setting the new
'colorspace_conv' module parameter to 1. This is a temporary solution, so
within a few months deprecated code will be entirely removed.

[PATCH] fix the barrier IDE detection logic
This fixes the logic so we always check for the cache. It also defaults to
safer behaviour for the non cache flush case now we have the right bits in
the right places. I've also played a bit with timings - the worst case
timings I can get for the flush are about 7 seconds (which I'd expect as
the engineering worst cases will include retries)
Probably what should happen is that the barrier logic is enabled providing
the wcache is disabled. I've not meddled with this as I don't know what
the intended semantics and rules are for disabling barrier on a live disk
(eg when a user uses hdparm to turn on the write cache). In the current
code as with Jens original that cannot occur.
I've also fixed the new printk's as per a private request from Matt Domsch.

[PATCH] Root reservations for strict overcommit
This was on my TODO list for a while and it turns out someone already fixed
the armwaving overcommit mode for the same problem. It is easy to get into
a situation where you have no overcommit and nothing can be done because
there is no memory to clean up the stable but non-useful state of the
machine.
The fix is trivial and duplicated from the armwaving overcommit code path.
The last 3% of the memory can be claimed by root processes only. It isn't
a cure but it does seem to solve the real world problems - at least
providing you have enough memory for 3% to be useful 8).
