This adds a "timbase" entry in /proc/cpuinfo like p/iSeries that
provides the CPU timebase frequency.  It is using by a all sort of
performance analysis tools we are hacking in house.

It also remove a useless bit about the l2 cache that was copied over
from ppc32.

I've had reports of flicker that appear with large (23") flat panels
and radeonfb. From experiments, it appears that forbiding the "odd"
PLL divider values fix it (like it fixes the blur problem on TMDS2).

There should not be anything special with TMDS1 and "odd" PLL values
though, so the problem may be subtly different (a bandwidth problem),
but until I have proper bandwidth calculation and access to this
monitor, the following patch is an acceptable workaround (Odd PLL values
aren't that useful anyway)

This fixes the permedia2 framebuffer driver to the new API.

[ Currently it doesn't even compile.  This only touches the current
  permedia driver.  ]

* Tidy up some of the arguments to iommu_*()
* Comment cleanup
* Don't bump the hint to the next block for large allocs, to avoid
  fragmentation.
* Simplify vmerge logic during SG allocations
* Move the memory barriers from the bus-specific parts into the common
  code.

Some changes are mine, some are from Ben Herrenschmidt.

- fix bug introduced by my recent fixes
  (do not try to disable 66MHz clock on PDC20246)
- cleanup cable verification code a bit
- remove unused macros (leftovers from driver split-up)
  and duplicated define from pdc202xx_old.h

	parport driver list turned into list.h one; parport/share.c code that
works with that list got cleaned up.

	parport_enumerate() is gone.  The last caller was under ifdef that
never had been true.  Function itself is removed, port list handling
cleaned up (now we can do that, since drivers don't mess with the list
directly), tons of racy crap removed from parport/share.c

	parport_sunbpp switched to keeping track of the ports it had
created; in module_exit it uses the private list instead of messing
with parport_enumerate().  Added check for sbus_ioremap() failure in
port initialization.

	parport_pc switched to keeping track of the ports it had
created; in module_exit it uses the private list instead of messing
with parport_enumerate().
	Added compile fix for configs that have CONFIG_PARPORT_PC_FIFO turned
off (from -mm).

	parport_announce_port() was always called right after
parport_proc_register().  Call shifted into parport_announce_port().
Similar for parport_remove_port() and parport_proc_unregister().

	parport_unregister_port() is split; parport_remove_port() does
what parport_unregister_port() used to do sans the final parport_put_port()
call.
	Callers updated; many of them needed only parport_put_port() (failure
exit paths where we never had the port announced to drivers).
	Fixed multiple races on port removal by shifting parport_remove_port()
in front of the code that releases irq/io ports/etc.

	references to slave ports of mux added to struct parport.
parport_daisy_init() doesn't go through parport_announce_port() for mux
slaves anymore; parport_annouce_port() deals with found ones itself.
Error handling sanitized, races on unregistration fixed.

	parport_pc_probe_port() sanitized; leaks fixed.

	parport_pc options parsing moved to parport_pc.c; parport/init.c is
gone.
	Warning fixes from -mm added.

	Registration of sysctls turned into module_init().

	Init of low-level drivers (except parport_pc) turned into module_init().

	Exports moved from parport/init.c to files where functions are
actually defined.

This patch contains the following:
1.  Fix up the pcie and shpc options to make it easier for distros
    to use as what we have discussed;
2.  Fix bug encountered when installing the drivers on non-hotplug
    systems;
3.  Put PCI_CAP_ID_SHPC in include/linux/pci.h
