- crash due to redundant dst_release.
- setting expire timeout on wrong route
- wrong mtu is selected when device mtu changed while device is down
- not working pmtu discovery timeout on cloned routes
- more reasonable behaviour on administrative increase of device mtu
- Ported to 2.5.44 by Alexey N. Kuznetsov.

- Changed dst named metrics, to RTAX_MAX metrics array.
- Add inline shorthands to access them
- Add update_pmtu and get_mss to DST ops.
- Add path component to DST, it is DST itself by default.

This also buries ip_proc.c.

Also move the fib code back to the fib implementation, and that will
now be done for udp and arp, then finally burying the ip_proc stillborn.

The problem was that when the refcount hit 0, it was unconditionally
assuming that it had been added, which is wrong.  The patch below
corrects that, and fixes the Oops when loading the floppy driver.

Several ports (x86-64,ppc64,sparc64) which do 32bit ioctl emulation
have functions for drivers to let them define their own translation
handlers. So far it was a bit complicated to use because there
was no standard include file that declares the prototypes for this
stuff. Then drivers and other subsystems can start to declare their own
ioctl translation handlers.

This patch add include/linux/ioctl32.h to fix this.

The actual implementation is in arch specific code. It has been coordinated
with DaveM and Anton.

This patch is needed for the x86-64 merge I sent in separate mail.

There is currently no preprocessor symbol that the drivers can test
to see if they should use this. So far they have to check arch symbols.
This will be fixed later when all 64bit ports that need it add the dynamic
ioctl registration API too (that's ia64,s390x,mips64)

This fixes a few files that got lost with the last merge and merges
with 2.5.43/i386.  Only changes architecture specific files.

It depends on one other patch (for linux/ioctl32.h) which I'm sending
separately.

Changes:
- Include missing files (pageattr.c) and Makefile changes
- Update IA32 subsystem. Various small fixes and a big merge
  with sparc64.
- Change HZ to 1000
- Merge some of the 2.5.43/i386 profiling changes. No full oprofile yet.
- Fix many warnings
- Update defconfig
- Various other smaller cleanups and bugfixes.
