These patches contain the following linux kernel bug fixes:

Description:
kernel: user readable uninitialized kernel memory.
Symptom:
None.
Problem:
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.
Solution:
Fix the copy_from_user function to clear the remaining bytes of the kernel buffer after a user space fault.
Problem-ID:
27706
Description:
qeth: stack trace with msg 'inconsistent lock state'.
Symptom:
messages
[ 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]
Problem:
This was discovered on a higher kernel level using the service 'Lock dependency validator'.
Solution:
bhs must be disabled when accessing neighbor tables.
Problem-ID:
26014
