Registering a new protocol of type SOCK_STREAM with a protocol value other
than IPPROTO_TCP will override TCP if the application passes 0 as the protocol
to the socket() call.
socket(AF_INET, SOCK_STREAM, 0)
I guess many applications follow this syntax as they assume TCP is the default
protocol for SOCK_STREAM type.
The same holds true for SOCK_DGRAM type sockets assuing UDP as the default.

This is due to the insertion of a new inet_protosw entry into the inetsw list
of a particular type at the head of the list. inet_create() uses the first
entry in the list if a wild-card protocol is passed.

The following patch fixes the insertion of a new entry so that it is added
after the last permanent entry in the list. This makes sure that the new 
entries do not override any existing permanent entries.

This patch adds initialization for forgotten rt_cache_stat.
However, kmalloc_percpu() may need things like kmalloc_percpu_zeroed().

This potentially helps debugging, since otherwise a double fault
would generate a triple fault and then reboot the machine. Now
instead it can print out a note about where the problem happened,
unless all the kernel data structures are truly buggered.

it's a noop in 2.5 now that the behvaiour of implicitly exporting
all symbols is gone.

This patch removes the devfs interface code in mtrr that has been
stubbed out by an ifdef forever.  It's one of the few remaining users
of regular files on devfs so there's some urge for me to get rid of it :)

Use cdevname instead in the serial driver printk cut & pasted into about
a dozend places.

small updates to bring us nearer the lm_Sensors CVS (docs, comments,
missing statics, named initializers).  I still need to review their
actual code changes before submitting those..

the number of metadata buffers. Use the same techniques as the
regular linux buffer cache here.

use more hash buckets for holding xfs metadata, and use the same
hash algorithm as the regular buffer cache.

this was always there, but exposed by the last change in
this area and made much more likely.
