Mostly code on the bind path, splitting out to pf and af family
specific functions.   Minor code cleanups/fixes mixed in.

Yet more address split out, but with the sideeffect that PF_INET6 
sockets can accept v4 addresses.   Another sideeffect is that this 
fixes an issue with the destination lookup code to deal with wildcards,
as the previous code was not considering the wildcard a match and
consequently doing a second lookup.

This is just more address cleanup really, but the sideeffect is that 
this enables the autobinding on PF_INET6 sockets.

This patch will break some userspace monitoring apps in the name of
having sane disk statistics in 2.6.x.

Patch from Rick Lindsley <ricklind@us.ibm.com>

In 2.5.46, there are now disk statistics being collected twice: once
for gendisk/hd_struct, and once for dkstat.  They are collecting the
same thing.  This patch removes dkstat, which also had the disadvantage
of being limited by DK_MAX_MAJOR and DK_MAX_DISK. (Those #defines are
removed too.)

In addition, this patch removes disk statistics from /proc/stat since
they are now available via sysfs and there seems to have been a general
preference in previous discussions to "clean up" /proc/stat.  Too many
disks being reported in /proc/stat also caused buffer overflows when
trying to print out the data.

The code in led.c from the parisc architecture has not apparently been
recompiled under recent versions of 2.5, since it references
kstat.dk_drive which doesn't exist in later versions.  Accordingly,
I've added an #ifdef 0 and a comment to that code so that it may at
least compile, albeit without one feature -- a step up from its state
now.  If it is preferable to keep the broken code in, that patch may
easily be excised from below.

We're currently incrementing /proc/vmstat:pgalloc in front of the
per-cpu page queues, and incrementing /proc/vmstat:pgfree behind the
per-cpu queues.  So they get out of whack.

Change it so that we increment the counters each time someone requests
a page.  ie: they're both in front of the queues.

Also, remove a duplicated prep_new_page() call and as a consequence,
drop the whole additional list walk in rmqueue_bulk().

There was some strange code in the __getblk()/__find_get_block()/
__bread() area which was performimg multiple bh_lru_install() calls as
well as multiple touch_buffer() calls.

Fix all that up.  We only need to run bh_lru_install() and
touch_buffer() in __find_get_block().  Because if the block wasn't
found, __getblk() will create it and will re-run __find_get_block().

Also document a few things and make a couple of internal symbols static
to buffer.c

Also, don't run __find_get_block() from within
unmap_underlying_metadata().  We hardly expect to find that block
inside the LRU.  And we hardly expect to use it as metadata in the near
future so there's no point in letting it evict another buffer if we
found it.  So just go straight into the pagecache lookup for
unmap_underlying_metadata().

This patch eliminates zap_hugetlb_resources, along with its usages.
This actually fixes bugs, as zap_hugetlb_resources was itself buggy.

Patch from William Lee Irwin III <wli@holomorphy.com>

Idle time accounting is disturbed by the iowait statistics, for several
reasons:

(1) iowait time is not subdivided among cpus.
        The only way the distinction between idle time subtracted from
        cpus (in order to be accounted as iowait) can be made is by
        summing counters for a total and dividing the individual tick
        counters by the proportions. Any tick type resolution which is
        not properly per-cpu breaks this, meaning that cpus which are
        entirely idle, when any iowait is present on the system, will
        have all idle ticks accounted to iowait instead of true idle time.

(2) kstat_read_proc() misreports iowait time
        The idle tick counter is passed twice to the sprintf(), once
        in the idle tick position, and once in the iowait tick position.

(3) performance enhancement
        The O(1) scheduler was very carefully constructed to perform
        accesses only to localized cachelines whenever possible. The
        global counter violates one of its core design principles,
        and the localization of "most" accesses is in greater harmony
        with its overall design and provides (at the very least) a
        qualitative performance improvement wrt. cache.

The method of correcting this is simple: embed an atomic iowait counter
in the runqueues, find the runqueue being manipulated in io_schedule(),
increment its atomic counter prior to schedule(), and decrement it
after returning from schedule(), which is guaranteed to be the same one,
as the counter incremented is tracked as a variable local to the procedure.
Then simply sum to obtain a global iowait statistic.

(Atomicity is required as the post-wait decrement may occur on a different
cpu from the one owning the counter.)

io_schedule() and io_schedule_timeout() are moved to sched.c as they must
access the runqueues, which are private to sched.c, and nr_iowait() is
created in order to export the sum of all runqueues' nr_iowait().

A patch from Janet Morgan <janetmor@us.ibm.com>

If you feed an iovec with a bad address not at the zeroeth segment into
readv or writev, it returns the wrong value.

	iovec 1:  base is 8050b20 len is 64
	iovec 2:  base is ffffffff len is 64
	iovec 3:  base is 8050ba0 len is 64

The writev should return 64 bytes but is returning 128

This is because we've added the new segment's length into `count'
before running access_ok().

The patch changes it to fix that up on the slow path, if access_ok() fails.

DOH!!! Somebody clone me a replacement brain: I must have burnt
another fuse.  It turns out the new readpages was evading our
read/write serialization.

This broke things like 'ld' over NFS, which rewrites chunks of
files it has already written.

last direct call into fs code is gone

Sufficient locking for fifo_open is provided by the inode semaphore.

- fix loading of another configuration
- accept longer strings in configuration
- move conf_filename to mconf.c (it's the only user)
- fix off by one error during string scanning

I enhanced the sendfile method so that we could pass a proper actor to
it (which exposes the full power of the internal implementation).

Now knfsd calls the sendfile vector rather than depending on a
readpage() that hasn't been set up fully.

Sorry, one small goof...

Use new "nmi_enter/exit()" which acts the same as the regular irq
entries (increases the preempt count appropriately), but doesn't try to
start processing softirqs on nmi exit (it just decreases the count).
