When the source address of a tunnel is given as 0.0.0.0 do a routing lookup
to get the real source address for the destination and fill that into the
acquire message. This allows to specify policies like this:
spdadd 172.16.128.13/32 172.16.0.0/20 any -P out ipsec
esp/tunnel/0.0.0.0-x.x.x.x/require;
spdadd 172.16.0.0/20 172.16.128.13/32 any -P in ipsec
esp/tunnel/x.x.x.x-0.0.0.0/require;

There are errors and inconsistency in the display of NIP6 strings.
ie: net/ipv6/ip6_flowlabel.c
There are errors and inconsistency in the display of NIPQUAD strings too.
ie: net/netfilter/nf_conntrack_ftp.c
This patch:
adds NIP6_FMT to kernel.h
changes all code to use NIP6_FMT
fixes net/ipv6/ip6_flowlabel.c
adds NIPQUAD_FMT to kernel.h
fixes net/netfilter/nf_conntrack_ftp.c
changes a few uses of "%u.%u.%u.%u" to NIPQUAD_FMT for symmetry to NIP6_FMT

Add hotplug cpu support to salinfo.c.
The cpu_event field is a cpumask so use the cpu_* macros consistently,
replacing the existing mixture of cpu_* and *_bit macros.
Instead of counting the number of outstanding events in a semaphore and
trying to track that count over user space context, interrupt context,
non-maskable interrupt context and cpu hotplug, replace the semaphore
with a test for "any bits set" combined with a mutex.
Modify the locking to make the test for "work to do" an atomic
operation.

This patch separates the sn_flush_device_list struct into kernel and
common (both kernel and PROM accessible) structures. As it was, if the
size of a spinlock_t changed (due to additional CONFIG options, etc.) the
sal call which populated the sn_flush_device_list structs would erroneously
write data (and cause memory corruption and/or a panic).
This patch does the following:
1. Removes sn_flush_device_list and adds sn_flush_device_common and
sn_flush_device_kernel.
2. Adds a new SAL call to populate a sn_flush_device_common struct per
device, not per widget as previously done.
3. Correctly initializes each device's sn_flush_device_kernel spinlock_t
struct (before it was only doing each widget's first device).

I originally thought this was an bug only in the SN code, but I think I
also see a hole in the generic IA64 tlb code. (Separate patch was sent
for the SN problem).
It looks like there is a bug in the TLB flushing code. During context switch,
kernel threads (kswapd, for example) inherit the mm of the task that was
previously running on the cpu. Normally, this is ok because the previous context
is still loaded into the RR registers. However, if the owner of the mm
migrates to another cpu, changes it's context number, and references a
page before kswapd issues a tlb_purge for that same page, the purge will be
done with a stale context number (& RR registers).

Increasing the module ref count at registration will block the module from

all. This patch removes the owner field from the struct registered with

This patch changes device_shutdown() to use the newly introduced safe
reverse list traversal. We experienced loops on system reboot if we had
removed and re-inserted our device from the device list.
We noticed this problem on PPC405. Our PCI IDE device comes and goes a lot.
Our hypothesis was that there was a loop caused by the driver->shutdown
freeing memory. It is possible that we do something wrong as well, but
being unable to reboot is kind of nasty.

Add bus_type probe, remove and shutdown methods to replace the
corresponding methods in struct device_driver. This matches
the way we handle the suspend/resume methods.
Since the bus methods override the device_driver methods, warn
if a device driver is registered whose methods will not be
called.
The long-term idea is to remove the device_driver methods entirely.
