The alignment exception used to only check the exception table for
-EFAULT, not for other errors. That opens an oops window if we can
coerce the kernel into getting an alignment exception for other reasons
in what would normally be a user-protected accessor, which can be done
via some of the futex ops. This fixes it by always checking the
exception tables.

this patch is required to get a SIS964 based motherboard ethernet working
(FSC D1875) (picking the #1 transceiver, instead of the last one, in case
no known ones were found might be a better default, and would have worked
in this case too)

This patch is identical to that introduced in
1a1276e7b6cba549553285f74e87f702bfff6fac to the Linus' 2.6 development tree
by Alan Cox.

'This is based on the proposed patches flying around but also checks that
the device in question is new enough to have word 93 rather thanb blindly
assuming word 93 == 0 means SATA (see ATA-5, ATA-7)' -- Alan Cox

Required for my SATA drive on an Asus Pundit-R to operate above 33MBps.

In bugzilla #6941, Jens Kilian reported:

"The function befs_utf2nls (in fs/befs/linuxvfs.c) writes a 0 byte past the
end of a block of memory allocated via kmalloc(), leading to memory
corruption.  This happens only for filenames which are pure ASCII and a
multiple of 4 bytes in length.  [...]

Without DEBUG_SLAB, this leads to further corruption and hard lockups; I
believe this is the bug which has made kernels later than 2.6.8 unusable
for me.  (This must be due to changes in memory management, the bug has
been in the BeFS driver since the time it was introduced (AFAICT).)

Steps to reproduce:
Create a directory (in BeOS, naturally :-) with files named, e.g.,
"1", "22", "333", "4444", ...  Mount it in Linux and do an "ls" or "find""

This patch implements the suggested fix. Credits to Jens Kilian for
debugging the problem and finding the right fix.

Two different exports with the same name are not a good idea:

$ grep -r EXPORT_SYMBOL\(dmasound_init\) *
drivers/media/video/saa7134/saa7134-core.c:EXPORT_SYMBOL(dmasound_init);
sound/oss/dmasound/dmasound_core.c:EXPORT_SYMBOL(dmasound_init);
$

This patch renames the saa7134 dmasound_{init,exit} to
saa7134_dmasound_{init,exit}.

The ->set_mac_address handlers expect a pointer to a
sockaddr which contains the MAC address, whereas
IFLA_ADDRESS provides just the MAC address itself.

So whip up a sockaddr to wrap around the netlink
attribute for the ->set_mac_address call.

Use proper upper limits for the loops and check for all error
conditions.
