I've had ia32-discontigmem under test for a month, uneventfully.  Possibly
because I don't have a machine to test it on....

A major part of this work is a general move to convert the low-level
memory management to consistently use pageframe numbers.  It's a bit
schizo at present..

This patch was written by Martin Bligh.  A version of this patch is in
the 2.4 aa tree.

It changes the unsigned longs node_start_paddr and zone_start_paddr to
page frame numbers.  This is necessary because a PAE address is 36 bits
and cannot be represented in an unsigned long.

 - The per-node physical memory start address node_start_paddr becomes
   a pfn, node_start_pfn.

 - The per-zone physical memory start address zone_start_paddr becomes
   a pfn, zone_start_pfn.

 - free_area_init_node() takes a pfn rather than a physical address.

Patricia has tested this patch on the following configurations: UP,
SMP, SMP PAE, multiquad, multiquad PAE, multiquad DISCONTIGMEM,
multiquad DISCONTIGMEM PAE.

The rmap locking inlines are causing some header file
dependency/ordering problems - move them out of page-flags.h and into
their own header file.

This adds IBM thinkpads to a list of mainboards that should not be
scanned by i2c sensors during detection phase.

OK, Linus, you are right... there are enough instances of this we are
not going to find them all (although I suspect Andrew's slab.c fixes
will cover most of the cases).  Further, I think we can should actually
purposely call preempt_schedule() in certain cases after interrupt
reenable to check for reschedules...

Let's just make it a rule "no preemption if interrupts are off" and
enforce that.

This fixes various instances of the interrupt flag variable not being
the proper `unsigned long', most notably kernel/softirq.c ...

This is a cleanup of the sigio/sigurg code.

Summary:
  o Removed sk->proc, SIGURG now sent via vfs, credentials checked
    during delivery.
  o SIOCSPGRP etc. ioctls use vfs, and work now for SIGIO as well
    as SIGURG.
  o Removed socket fcntl code.
  o Consolidate lsm file_set_fowner() hooks.
  o Fixed fowner race.
  o Fixed associated mainline memory leak in fcntl_dirnotify().

contortions instead of just calling "end_that_request_first()" with
the proper sector count.

This was _bad_. Major floppy corruption, and possibly the reason
for other block device corruption for any driver that generated
partial results for a block device request.

ptrace.h needs struct task_struct, so we need to include <linux/sched.h>.

bools don't have depencies, only dep_bools do.  Use three-space indents.

Fix various Makefiles to really list the objects which use EXPORT_SYMBOL.

#define __NO_VERSION__ has been unnecessary for a long time, so here it

Defining CONFIG_DEVFS_FS in two different places does not work correctly.
Nobody objected on linux-ia64, so I just removed the statements
unconditionally enabling devfs on IA64/SNI.

Pointed out by Greg Banks.

I don't know if the current form is harmless or not, but it is
definitely incorrect.  The patch below corrects the compile failure, as
well as the multi-statement macro defines used in bare if statements;
please apply.

The BUG_ON(p->ptrace) will be called if the CLONE_DETACH process is
traced.  This patch removes BUG_ON(p->ptrace), and also removes a
workaround for it in sys_wait4().
