Some filesystems can get overflows when their link-count exceeds
65534.  This patch increases the kernels internal resolution for this
and also has a check for the old-system call paths to return and error
(-EOVERFLOW) as required (as suggested by Al Viro).

This patch results in too much idle time under certain
loads, and while that is being looked into we're better
off just reverting the change.

This patch fixes orphaned expectations, which can occur when helpers create
expectations for unconfirmed conntracks and the packet is dropped before
the conntrack is confirmed.

Tracked down by Raivis Bucis <raivis@mt.lv>

This patch fixes an oops while listing /proc/net/ip_conntrack.

When a helper sets up expectations based on the first packet (tftp),
NAT can still change the packet and cause conntrack to look for a new helper
based on the new tuple. When no helper is found, expectant->helper will be
NULL, which leads to an oops in print_expect().
 
Only assign a new helper in ip_conntrack_alter_reply() if there are no
expectations.

nfs_writepage() refuses to write back mapped pages at all on the page
reclaim path, causing systems to get locked up when there's a lot of dirty
mmapped data around.  The patch changes NFS so that it will start I/O
against these pages.

The code as it stands is designed to defer writeout to pdflush which can do
larger, more efficient I/Os.  But there shouldn't be much traffic by this
path, and going slow is better than not going at all.

Patch originally from Trond.

VIA chipsets are broken and don't work with IOMMU enabled. For some mysterious
reason (the IOMMU logic is actually in the CPU) they manage to corrupt all
data going through the aperture to PCI devices.

There was a workaround previously that enabled the slower softmmu when VIA is 
detected on the normal IOMMU path (when there is more than 3GB of memory). But
CONFIG_IOMMU_DEBUG took a short cut that was not handled, which ended up with 
VIA systems not booting when this option is enabled.

This patch enables the workaround with CONFIG_IOMMU_DEBUG/iommu=force too

The fast system-call fall-back-path has a race: it reads PSR, modifies
some bits, then writes back the new PSR.  Unfortunately, the contents
of PSR may change between reading and writing it.  For example, an
interrupt could occur which could trigger a context-switch.  The
context-switch might in turn flush the floating-point-high (FPH)
partition to memory, clear PSR.MFH, and set PSR.DFH.  To prevent this
race, the patch below turns off PSR.I before reading PSR.

This fixes a floating-point corruption problem that was observed on a
system with a libc which has the fast system-call support enabled.

The performance impact is minimal (on the order of a handful of cycles).

I waffled over this for ages.  On balance, I think it's best to mark those
bh's as uptodate.

And on reflection, I'm not sure why we go bringing ramdisk blockdev pages
uptodate all over the place anyway.  But ramdisk is weird and it passes
testing.  Let those dogs sleep.

Cleanup s390* string functions.  This replaces the 31/64 bit assembler
files (strcmp[64].S, strcpy[64].S & strncpy[64].S) with a single string.c
file that uses some inline assemblies to issue the string instructions.  In
addition some more of the generic string function got an architecture
