pmac mixer update from shadow register on resume and switching DRC on headphone plug

The attached patch improved the pmac driver by implementing updating the
mixer from the shadow register after a resume or headphone interrupt, as
well as automatically selecting DRC on headphone plug.

For normal line-out one does not want the DRC, but it should
automatically be reenabled after the headphone is unplugged: Otherwise
the power to the internal speakers is high enought to destroy them
(happend once to my iBook - when it still had warrenty ... ;-)

On some platforms (notably power5) you can't enable surveillance
(firmware/service processor watchdog) from the kernel - you have to do
it in the firmware.

This patch changes enable_surveillance() to make the message that is
printed in this situation more informative.  Additionaly, the rtas_call
was changed to rtas_set_indicator so as to avoid having to handle
RTAS_BUSY returns.

The code doesn't actually _care_ about 32/64-bit issues,
only about F_SETLK vs F_SETLKW, and the F_SETLK64 doesn't
exist except as a compatibility thing on 64-bit architectures
(since the regular one already _is_ 64-bit, of course).

   call allows for the client to request that the mtime and/or atime
   of an inode be set to the current server time, the given (client)
   time, or not changed.  The set-to-current-server value is used
   when you run "touch file" on the client.

The NFSv2 RFC defines no such encoding for the sattr structure. 
   However Solaris and Irix machine obey a convention where passing
   the invalid value mtime.useconds=1000000 means "set both mtime and
   atime to the current server time".  The convention is documented
   in the book "NFS Illustrated" by Brent Callaghan.  The patch below
   implements this convention for the Linux client and server (hence
   multiple To:s).

   direct I/O support for NFS files.  The 2.4 VFS O_DIRECT logic was
   block based, thus the NFS client had to provide a minimum
   allowable blocksize for O_DIRECT reads and writes on NFS files. 
   For various reasons we chose 512 bytes. In 2.6, there is no
   requirement for a minimum blocksize.  NFS O_DIRECT reads and
   writes can go to any byte at any offset in a file.  Thus we revert
   the blocksize setting for NFS file systems to the previous
   behavior, which was to advertise the "wsize" setting as the
   optimal I/O block size.  This improves the performance of
   applications like 'cp' which use this value as their transfer
   size.

This patch also exposes the server's reported disk block size in the
   f_frsize of the vfsstat structure.
