The 80c wire bit is bit 13, not 14. Bit 14 is always 1 if word93 is
implemented. This increases the chance of incorrect wire detection
especially because host side cable detection is often unreliable and
we sometimes soley depend on drive side cable detection. Fix the test
and add word93 validity check.

With this change the sysctl inodes can be cached and nothing needs to be done
when removing a sysctl table.
For a cost of 2K code we will save about 4K of static tables (when we remove
de from ctl_table) and 70K in proc_dir_entries that we will not allocate, or
about half that on a 32bit arch.
The speed feels about the same, even though we can now cache the sysctl
dentries :(
We get the core advantage that we don't need to have a 1 to 1 mapping between
ctl table entries and proc files. Making it possible to have /proc/sys vary
depending on the namespace you are in. The currently merged namespaces don't
have an issue here but the network namespace under /proc/sys/net needs to have
different directories depending on which network adapters are visible. By
simply being a cache different directories being visible depending on who you
are is trivial to implement.

The current logic to walk through the list of sysctl table headers is slightly
painful and implement in a way it cannot be used by code outside sysctl.c
I am in the process of implementing a version of the sysctl proc support that
instead of using the proc generic non-caching monster, just uses the existing
sysctl data structure as backing store for building the dcache entries and for
doing directory reads. To use the existing data structures however I need a
way to get at them.

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name. Which is
pain for caching and the proc interface never implemented.
I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.
So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

Add support for using a filesystem UUID to identify and export point in the
filehandle.
For NFSv2, this UUID is xor-ed down to 4 or 8 bytes so that it doesn't take up
too much room. For NFSv3+, we use the full 16 bytes, and possibly also a
64bit inode number for exports beneath the root of a filesystem.
When generating an fsid to return in 'stat' information, use the UUID (hashed
down to size) if it is available and a small 'fsid' was not specifically
provided.

On ia64, drivers/base/dma-mapping.c doesn't build because it calls
dma_alloc_noncoherent() and dma_free_noncoherent(), which appear to be
terminally broken; the calls end up generating errors like
drivers/base/dma-mapping.c: In function 'dmam_noncoherent_release':
drivers/base/dma-mapping.c:32: error: 'struct ia64_machine_vector' has no member named 'platform_dma_free_coherent'
because the multiple levels of macro expansion in <asm/dma-mapping.h> and
<asm/machvec.h> end up turning a call to dma_free_noncoherent() into
ia64_mv.platform_dma_free_coherent (instead of the intended
ia64_mv.dma_free_coherent).
This patch fixes this by converting dma_{alloc,free}_noncoherent() into
inline functions that call the corresponding coherent functions, instead of
trying to do this with macros.

udbg_early_init() is a function used on 64 bit systems, which
initializes whichever early udbg backend is configured. This function
is not called on 32-bit, however if btext early debug is enabled it
does have an explicit, inline, #ifdef-ed assignment performing
analagous initialization.
This patch makes things more uniform by folding the btext
initialization as an option into udbg_early_init() and calling that
from the 32-bit setup path.

standard driver model style; document them.
- Minor doc updates to highlight zero-initialized fields in drivers, and

If any i2c drivers were previously using the old suspend/resume calls
in "struct driver", they were getting warning messages ... and will
now no longer work. Other than that, this patch changes no behaviors;
and it lets I2C drivers use conventional PM and shutdown support.
