 - Avoid using i2c_client.adapter, since that field is redundant and

 - Extend type enum to include various RTCs this is expected to

It also cleans up the support for multiple chip types, and fixes a

We want it to be possible for users to restrict exports both by IP address and
by pseudoflavor.  The pseudoflavor information has previously been passed
using special auth_domains stored in the rq_client field.  After the preceding
patch that stored the pseudoflavor in rq_pflavor, that's now superfluous; so
now we use rq_client for the ip information, as auth_null and auth_unix do.

However, we keep around the special auth_domain in the rq_gssclient field for
backwards compatibility purposes, so we can still do upcalls using the old
"gss/pseudoflavor" auth_domain if upcalls using the unix domain to give us an
appropriate export.  This allows us to continue supporting old mountd.

In fact, for this first patch, we always use the "gss/pseudoflavor"
auth_domain (and only it) if it is available; thus rq_client is ignored in the
auth_gss case, and this patch on its own makes no change in behavior; that
will be left to later patches.

Note on idmap: I'm almost tempted to just replace the auth_domain in the idmap
upcall by a dummy value--no version of idmapd has ever used it, and it's
unlikely anyone really wants to perform idmapping differently depending on the
where the client is (they may want to perform *credential* mapping
differently, but that's a different matter--the idmapper just handles id's
used in getattr and setattr).  But I'm updating the idmapd code anyway, just
out of general backwards-compatibility paranoia.

knfsd: nfsd4: vary maximum delegation limit based on RAM size

Our original NFSv4 delegation policy was to give out a read delegation on any
open when it was possible to.

Since the lifetime of a delegation isn't limited to that of an open, a client
may quite reasonably hang on to a delegation as long as it has the inode
cached.  This becomes an obvious problem the first time a client's inode cache
approaches the size of the server's total memory.

Our first quick solution was to add a hard-coded limit.  This patch makes a
mild incremental improvement by varying that limit according to the server's
total memory size, allowing at most 4 delegations per megabyte of RAM.

My quick back-of-the-envelope calculation finds that in the worst case (where
every delegation is for a different inode), a delegation could take about
1.5K, which would make the worst case usage about 6% of memory.  The new limit
works out to be about the same as the old on a 1-gig server.

Both lockd and (in the nfsv4 case) nfsd enforce a "grace period" after reboot,
during which clients may reclaim locks from the previous server instance, but
may not acquire new locks.

Currently the lockd and nfsd enforce grace periods of different lengths.  This
may cause problems when we reboot a server with both v2/v3 and v4 clients.
For example, if the lockd grace period is shorter (as is likely the case),
then a v3 client might acquire a new lock that conflicts with a lock already
held (but not yet reclaimed) by a v4 client.

This patch calculates a lease time that lockd and nfsd can both use.

knfsd: exportfs: remove iget abuse

When the exportfs interface was added the expectation was that filesystems
provide an operation to convert from a file handle to an inode/dentry, but it
kept a backwards compat option that still calls into iget.

Calling into iget from non-filesystem code is very bad, because it gives too
little information to filesystem, and simply crashes if the filesystem doesn't
implement the ->read_inode routine.

Fortunately there are only two filesystems left using this fallback: efs and
jfs.  This patch moves a copy of export_iget to each of those to implement the
get_dentry method.

While this is a temporary increase of lines of code in the kernel it allows
for a much cleaner interface and important code restructuring in later
patches.

Of course, the code here might actually be buggy, in which case this patch
should not be applied?

Answer:

  No this field is ignored inside linux kernel.Yes this is ugly, but it's
  the CAPI spec for all OS.

  CAPI DATA_B3 Request/Indication CAPI Message has a mandatory field which
  represent the 32 bit buffer address of the payload data.  In linux the
  payload data do not use a sperate buffer, data follows directely after the
  CAPI Message in the same skb and we use this assumption inside the drivers,
  so we can ignore this field.

  Inside the linux CAPI implemetation we never use this field, so it could
  also have no value, but since random data in a message is bad as well (e.g.
  displayed in CAPI traces) we set is to the most adequate value.

  Outside the kernel the capi20 library sets the correct addresses (there is
  an optional second field for 64 bit adresses for 64 bit systems, we do not
  use here).

as the TLE6220 or TLE6230.  These can be viewed as output GPIOs specialized

interface to those GPIOs, and to the switch status they provide.

spi_mpc83xx.c underclocking hotfix

The MPC83xx SPI controller clock divider can divide the system clock by not
more then 1024.  The spi_mpc83xx driver does not check this and silently
writes garbage to the SPI controller registers when asked to run at lower
frequencies.  I've tried to run the SPI on a 266MHz MPC8349E with 100kHz
for debugging a bus problem and suddenly was confronted with a 2nd problem
to debug..  ;-)

The patch adds an additional check which avoids writing garbage to the SPI
controller registers and warn the user about it.  This might help others to
avoid simmilar problems.
