Andi has asked that I send these straight forward compatibility patches
to you and he will fix up any merge problems later.  These are the
outstanding patches for x86_64 against 2.5.60.

At Linux Conf AU, Willy asked me to send any further parisc compatibility
changes directly to you, so this is what I have outstanding.  Basically,
it is just the uses of compat_sigset_t that seemed to have been missed in
the previous merges.

This brings the x86-64 port uptodate in 2.5.60. Unfortunately I cannot
test too much because i constantly get deadlocks in exit/wait in initscripts
on SMP bootup. The kernel seems to still lose a lot of SIGCHLD. 2.5.59/SMP
had the same problem. Uniprocessor and SMP kernel on UP seems to work.

This patch only touches x86-64 specific files. It requires a few simple
changes to arch independent files that I will send separately.

 - Fixed a lot of obsolete/misleading configure help texts.
 - Remove old bootblock disk loader and support fdimage target for syslinux
   instead (H. Peter Anvin)
 - Fix potential fpu signal restore problem on 32bit emulation.
 - Merge with 2.5.60 i386 (hugetlbfs, acpi etc.)
 - Some fixes for local apic disabled modus.
 - Beginngs of S3 ACPI wakeup from real-mode (not working yet, don't use)
 - Beginnings of NUMA/CONFIG_DISCONTIGMEM support for AMD K8 (work in progress,
   port from 2.4): clean up memory mapping at bootup, generalize bootmem etc.
 - Fix 64bit GS base reload problem and reenable (Karsten Keil)
 - Fix race with vmalloc accesses from interrupt handlers disturbing page fault/
   similar race for the debug handler (thanks to Andrew Morton)
 - Merge cpu access primitives with i386
 - Revert to private module list for now because putting modules
   nto vmlist triggered too many problems.
 - Some cleanups, removal of unneeded code.
 - Let early __get_free_pages see consistent pda
 - Preempt disabled for now because it is too broken right now
 - Signal handler fixes
 - Fix do_gettimeofday to be completely lockless and reenable vsyscalls
 - Optimize context switch path a bit (should be ported to i386)
 - Get thread_info via stack for better code
 - Don't leak pmd pages
 - Clean up hardcoded task stack sizes.

Since daemonize now blocks all signals, this simplification is trivially
correct.

Not that it makes any difference on x86, but there may be
architectures that actually need it.

Add a name argument to daemonize() (va_arg) to avoid all the
kernel threads having to duplicate the name setting over and
over again.

Make daemonize() disable all signals by default, and add a
"allow_signal()" function to let daemons say they explicitly
want to support a signal.

Make flush_signal() take the signal lock, so that callers do
not need to.

Patch from Roland McGrath.

This patch replaces the assumption that > PAGE_OFFSET == kernel address
with testing for user_mode(regs) and inserting switch codes instead.

This patch allows the oprofilefs files to take entry in any base
instead of just base 10

This patch updates the horrible enum for the logical CPU type with a
string instead.

The below patch implements a P4 driver for OProfile, mostly written
by Graydon Hoare.

tasks (even if we don't otherwise need to wake anything up), since
otherwise later signals would see that signals are already pending and
wouldn't cause wakeups.

wake_up_forked_process() unconditionally enables interrupts.  It is called
from sched_init().  Enabling interrupts that early makes Anton's ppc64
machine lock up.

This fixes several trivial bounds/limits errors that were pointed out by
the Stanford Checker.

This fixes a potential divide-by-zero found by the Stanford Checker.

The few platforms that cannot use the generic
get_signal_to_deliver implementation cannot do
so because they do special things for ptraced
children.  This can be easily avoided and thus
all of the signal handling code duplication can
be eliminated.

This is the first part, which adds a platform hook
right before the parent of the ptraced child is woken.
Data can be passed in via a cookie argument.

The next part will be dealing with platforms
that need to muck with breakpoints in the child
in this same code block.

Patch from Marc Zyngier <mzyngier@freesurf.fr>

My previous round of EISA hacking left the 3c59x driver unable to
compile on non-PCI systems (that is, EISA only...).

This small patch fixes it.

Patch from Marc Zyngier <mzyngier@freesurf.fr>

Fix compilation of 3c509.c

Patch from: Eric Lammerts <eric@lammerts.org>

Every time you do a loop mount, a kernel thread is started (those
processes are called "loop0", "loop1", etc.). The problem is that when
it starts, it's counted as one of your processes. Then, it's
changed to be a root-owned process without correcting that count.

Patch below fixes the problem. It moves the bookkeeping of changing
current->user to a new function switch_uid() (which is now also used
by exec_usermodehelper() in kmod.c). The patch is tested.
