from 2.4-ac - it seems to cause hangs for people.

This tunes the volume control of maestro sound boards: The log
conversion seems not good for PCM and CD.  The volume buttons
incrementing / decrementing the main volume by 10 on 100 is too much,
much better set it to 5.

Memory leak fix: the allocated areas weren't referenced any more once the
original error path returned.

It used to depend on us having a signed type (which in turn is
incorrect for the later division).

alpha, ia64, PA, sparc already export the existing "utimes()" system
call (using 'timeval[2]' instead of 'utimebuf' like the old "utime()").

Make it available on x86 too..

Some minimum critical fixes for x86-64:

- Make it compile for uni processor again
- Tell BIOS about long mode
- Fix 32bit IPC (broken by earlier patch)

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
Fixes a crash
Updates to use the new ac97

This is the newer audio used in later ALi chipsets.
