These patches contain the following linux kernel bug fixes:

kernel: user readable uninitialized kernel memory.
A user space program can read uninitialized kernel memory by appending to a file from a bad address and then reading the result back. The cause is the copy_from_user function that does not clear the remaining bytes of the kernel buffer after it got a fault on the user space address.
Fix the copy_from_user function to clear the remaining bytes of the kernel buffer after a user space fault.
qeth: stack trace with msg 'inconsistent lock state'.
[ INFO: inconsistent lock state ]
inconsistent {in-softirq-W} -> {softirq-on-W} usage.
modprobe/758 [HC0[0]:SC0[0]:HE1:SE1] takes:
(&tbl->lock){-+-.}, at: [<000000008080c396>].
qeth_init+0x396/0x4e4 [qeth]
This was discovered on a higher kernel level using the service 'Lock dependency validator'.
bhs must be disabled when accessing neighbor tables.

Everybody should apply this patch.
