Merge from i386 for x86-64: move reboot functions to an own file.

Straightforward merge from i386: remove support for global cli for
x86-64

Update for the x86-64 PCI subsystem in 2.5.42.  Main new feature is PCI
IOMMU support through the K8 aperture.  This allows to use more than 4GB
of memory with 32bit PCI devices.  Also some other PCI changes, mostly
merges from i386.

Some bugfixes for the 32bit emulation for x86-64 and make it all compile
again.

Has rewritten ioctl registration code and some other updates.  New
system calls are supported.

It unfortunately broke some time ago by binfmt_elf changes for all
shared linked libraries.  Will fix that later.

New e820 memory map handling for x86-64.  Move it all to a new file and
clean it up a lot.  Add some simple allocator functions to deal with
holey e820 mappings cleanly A lot of this is preparation for NUMA (which
works in 2.4, but is not ported to 2.5 yet)

Update the early 32bit bootloader for x86-64.  This stuff is near
completely identical to i386, except for a few Makefile changes to tell
the x86-64 toolkit to compile in 32bit mode.

ACPI updates for x86-64/2.5.42

ACPI finally works now.

SPARC was unconditionally setting CONFIG_SERIAL_CORE_CONSOLE to y
and conditionally setting CONFIG_SERIAL_CORE depending on the Sparc
sub-drivers.  In addition, the core serial driver for SPARC is
always built, so we end up with link errors.

We instead make CONFIG_SERIAL_CORE{,_CONSOLE} dependent on building
the SPARC core driver (CONFIG_SERIAL_SUNCORE).

Problem: if another CPU is using lazy-TLB, the LDT flushing won't flush
the other CPU's LDT entry.

Fix: use active_mm instead of mm for the flush IPI.

we should allow read-write accesses - it's used for control, not
data.

Not perfectly clean yet, but uses the standard way to descend into subdirs
and gives me working vmlinux and linux targets without spurious rebuilds.

Fix buggy #if removal in iphase.c that crept in with the initcalls fixup.

This is the initial port of InterMezzo for 2.5.  It now compiles,
mounts, and completes I/Os successfully, but we are aware that more
needs to be done and we will do it as quickly as possible.

The timer-handling split patch moved cpufreq stuff from time.c to
timers/timer_tsc.c but not the corresponding #include <linux/cpufreq.h>
causing the build to fail.

The fix is simple.

Convert the tty_drivers list to use list_heads instead of open coded
doubly-linked lists.

Correct compiler warnings for 64 bit platforms and minor formatting cleanup and remove debug function that was causing a conflict with a function of the same name in SCSI
