This factors out the common bits of arch/powerpc/xmon/start_*.c into
a new nonstdio.c, and removes some stuff that was supposed to make
xmon's I/O routines somewhat stdio-like but was never used.
It also makes the parsing of the xmon= command line option common,
so that ppc32 can now use xmon={off,on,early} also.

The big i2c-viapro SMBus driver update which went into 2.6.14-git1
introduced a few minor issues. Nothing critical, but I would like a
few adjustments to be merged in to fix the following problems:
* VIA should not be spelled Via.
* Frodo Looijaard and Philip Edelbrock did not write the i2c-viapro
driver.
* When debugging is disabled, half of messages would be logged.
* Drop an unneeded masking.
* Some port reads can be avoided now that the transaction size is
passed as a parameter to vt596_transaction().
* SMBus Receive Byte transactions are used for probing too (for
EEPROMs), so hide errors on these too.

This patch kills include/linux/eeprom.h .
Rationale:
- it was only used by one single driver
- even this driver didn't do anything useful with it
- most of this file are non-inline and non-static functions (sic)
This removes include/linux/eeprom.h and cleans drivers/net/ns83820.c up.
If you think eeprom.h should be used more extensively, please consider:
- the code has to be moved from the header file to a .c file
- the currently empty write function has to be implemented
- ns83820.c or any other driver should actually use it
Noone did any of these during the more than 3 years eeprom.h already
exists...

An unbindable mount does not forward or receive propagation. Also
unbindable mount disallows bind mounts. The semantics is as follows.
Bind semantics:
It is invalid to bind mount an unbindable mount.
Move semantics:
It is invalid to move an unbindable mount under shared mount.
Clone-namespace semantics:
If a mount is unbindable in the parent namespace, the corresponding
cloned mount in the child namespace becomes unbindable too. Note:
there is subtle difference, unbindable mounts cannot be bind mounted
but can be cloned during clone-namespace.

umount is done under the protection of the namespace semaphore. This
can lead to intresting deadlocks when the last reference to a mount is
released, if filesystem code is in sufficiently nasty state.
This collects all the to-be-released-mounts and releases them after
releasing the namespace semaphore. That both reduces the time we are
holding namespace semaphore and gets the things more robust.
