This changes/fixes the optcd.c stack reduction patch from last week.

Alan and Jens objected to the kmalloc() in cdromread(), suggesting that
the read buffer should be allocated one time and held onto, so this
patch does that.

The systemcall interface for adding exports checked that
the filesystem was exportable.  The new interface doesn't...

This patch splits this functionality into a separate function
which is called from both sites.

This adds the PCI ids for some of the newer Apple chips.

This updates the battery charge calculations for powerbooks.  This is
Ben Herrenschmidt's work.

This updates the ADB (Apple desktop bus) driver used on macs and
powermacs.  The main change, from Ben Herrenschmidt, is that handlers
are called without a lock held now.  It also adds a way for userland to
obtain some information about individual ADB devices from the driver.

CROSS_64KB won't work as advertised due to missing parenthesis.

Pointed out by Joern Engel.

Just want to nip this in the bud :-)

Only used for (dubious) debugging purposes, and exposes
internal kernel state.

The previous handling of PCI class masks was too primitive: the
class field is not "all or nothing" but has base class, subclass
and interface fields.  This patch changes the alias form from:
pci:vNdNsvNsdNcN to pci:vNdNsvNsdNbcNscNiN.

This removes the extable list, and the struct exception_table, in
favour of just iterating through the modules.  Now all iteration is
within kernel/module.c, this is a fairly trivial cleanup.

This removes the symbol list, and the concept of kernel symbol groups,
in favour of just iterating through the modules.  Now all iteration is
within kernel/module.c, this is a fairly trivial cleanup.

By making module_text_address return the module it found, we
simplify symbol_put_addr significantly.

  This patch makes us of a new predefined macro, instead of having the code
  directly in the driver.

  Here are the changes for s390 to set .owner for tty_drivers
  and remove MOD_INC/DEC_USE_COUNT. Martin has already approved
  this.
