Deprecate the numerical sysctl name space. People can use /proc/sys
instead.

The numeric name space was never well maintained and especially
in distribution kernels is not very consistent (everybody has their
own extensions, conflicting with others). It's also a great
source of rejects when merging patches.  The name-based /proc/sys
is a much better interface for this, which people should use instead.

Discussion of this on l-k found no advocate for it, so it seems to not
be very popular anyways.

This patch deprecates numerical name space accesses to make it possible
to remove them in the future. The only exception is kernel.version,
which is used by glibc (this one has to be maintained forever)

 - __div64_32(): remove __attribute_pure__ qualifier from the prototype
   since this function obviously clobbers memory through &(n);

 - do_div(): add a check to ensure (n) is type-compatible with uint64_t;

 - as_update_iohist(): Use sector_div() instead of do_div().
   (Whether the result of the addition should always be stored in 64bits
   regardless of CONFIG_LBD is still being discussed, therefore it's
   unadderessed here);

 - Fix all places where do_div() was being called with a bad divisor argument.

Every failed SG_IO request is replayed second time without data
transfer.  Fix the problem by immediately purging the failed SG_IO
request from the request queue.

It fixes (among others)

where induced kernel crash occurs upon packet replay.

people not to remove the HAVE_KERNEL_CTX_SWITCH support that
the sparc drivers require.

Fix a FIXME.

- include/linux/wrapper.h doesn't exist in 2.5.75 and none of it's content
  is used by the driver;
- s/MINOR/minor/;
- KConfig/Makefile update.

Fixes security leak

Updates to use the new ac97

This is the newer audio used in later ALi chipsets.

This is used by some MIPS systems

This deals with several things
- Codecs that think they are modems but are not
- Abstracting modem detection out of drivers
- Abstracting digital switching out of drivers
- Codecs that have no volume control
- Codec plugins for specific setups
- Codec plugins for things like touchscreen/batmon on AC97
- More codec handlers

The plugin API is intentionally modelled on the other driver_register
type interfaces.
