Lots of x86-64 updates. Merge with 2.4 and NUMA works now. Also reenabled
the preemptive kernel. And some other bug fixes.
IOMMU disabled by default now because it has problems.

 - Add more CONFIG options for device driver debugging and iommu
   force/debug.  (don't enable iommu force currently)
 - Some S3/ACPI fixes/cleanups from Pavel.
 - Set MSG_COMPAT_* in msg_flags for networking 32bit emulation.
   This unfortunately still doesn't fix the fd passing problems.
 - Sync PCI IOMMU code with 2.4 (minor fixes, flush less often)
 - Really fix UP compilation (Pavel)
 - Reenable preempt
 - Fix CONFIG_DISCONTIGMEM bootup and enable.  Still needs more tuning.
 - Fix some bugs in topology discovery and clean code up.
 - Don't put unwind tables into object files
 - Some kernel debugging hooks
 - Move CPU detection into early real mode code to better interact with
   vesafb consoles
 - Initialize mode in real mode character output
 - New 32bit FPU signal save/restore
 - Various fixes in FPU handling in ptrace
 - Fix security holes in ptrace (32bit and 64bit)
 - Fix serial ioctl (including security hole)
 - Add bluetooth ioctls to 32bit emu (from sparc64)
 - Correctly enable si_val in queued signals in 32bit emulation
 - Rework SEM_STAT emulation.  LTP still fails unfortunately.
 - Fix error case in msg* emulation
 - Fix debug register access from ptrace (Michal Ludvig, me)
 - Fix handling of NULL arguments in 32bit execve
 - Fix some error cases for 32bit readv/writev (LTP still complains)
 - Remove rate control from unimplemented syscall warnings
 - Fix error message for missing aperture
 - Turn some APIC printks into Dprintk to make the bootup more quiet
 - Some fixes for no APIC (probably still broken), add disableapic
   option (untested)
 - Sync K8 MCE handler with 2.4.  Should work a lot better now.
 - Remove never used KDB hooks
 - Fix buffer overflow in command line copying
 - Merge from i386: use separate status word for lazy FPU state
 - Don't force the IOMMU for dma masks < 4GB.
 - Print backtrace in Sysrq-T (from Andrea)
 - Merge from i386: fix FPU race in fork.
 - Disable NX mode by default for now
 - Rewrite dump_pagetable
 - Fix off by one bug in ioremap (i386 merge)
 - Merge from i386: handle VIA pci bridge bugs
 - Disable NUMA ACPI support (no SRAT support yet)
 - Fix aio 32bit emulation
 - Increase 32bit address space to nearly 4GB
 - Add exit_group syscall
 - Fix TLS setting in clone (Ulrich Drepper)

The ACPI NUMA support doesn't work on x86-64 currently (no SRAT
parsing yet). Disable for now.

The new aio emulation in x86-64 needs a few aio symbols exported.
Export them.

In tcp_sendmsg, make sure we jump to the out label
when seglen is decremented to zero and no more iovecs remain.
This matches the do_tcp_sendpages logic and makes sure that
PSH is set correctly at the end of a write even if the write length
equals the current mss.

Fix more annoying compile problems due to wrong types
for comparing jiffies. This patch applies to alpha arch.

From Thomas Weyergraf.

Ivan.

- Check for parent PCI bus instead of bridge device to break the
  look in common_swizzle(). Functionally it's the same, but it's
  cleaner for PC-style host bridges (nautiluses).
- Generic PCI setup changes finally went in (thanks to rmk), so that
  FIXME in common_init_pci() can go.

Ivan.

It's possible to squeeze more bits out of lower half of pte,
but 32 seem to be a plenty...

We need to save one tblock for forced transactions, and only transactions
changing the inode allocation tables should be forced.

This is needed as we are still not using the driver core model for
matching up devices to drivers, but doing it by hand.  Once that is
changed, this will not be needed.
