Rename socket_info_t (which is used many, many times differently
within pcmcia) to "struct pcmcia_bus_socket".

Also, a couple of functions in ds.c can be converted to use the "struct
pcmcia_bus_socket" as argument instead of the socket number.

As we don't have a late_initcall in ds.c any more, we can't easily
distinguish between in-kernel drivers and those built as modules. This
information was used by cardmgr to detect whether "rmmod" makes
sense. As unloading of modules seems to be deprecated behaviour anyway
in 2.5., and the current driver unloading process is IMO broken
anyway, I don't shed any tears on this lost functionality.

Previously, "Driver Services" could only be called when the socket
drivers were initialized earlier. This caused an awful lot of
problems, especially when modprobe tried to load ds.ko and a pcmcia
card driver at once.

As all socket devices are registered with the driver model core as
being of "class_type pcmcia_socket_class", we can take use of that and
register them with "Driver Services" upon detection or upon
module loading of ds.c.

Also, the "I-need-two-initcalls-in-a-module"-tweak can go away.

Unfortunately, this patch reportedly breaks some RedHat pcmcia init
scritps - they relied on the failed loading of ds.c to detect that no
socket driver was loaded previously. To properly detect this, you
should take a look at the /sys/class/pcmcia_socket/devices directory.

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.

(1) use the builtin foo-$(BAR) mechanism of the 2.5 kbuild
(2) align all += foo.o statements
