Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Merge 'net' bug fixes into 'net-next' as we have patches that will build on top of them. This merge commit includes a change from Emil Goode (emilgoode@gmail.com) that fixes a warning that would have been introduced by this merge. Specifically it fixes the pingv6_ops method ipv6_chk_addr() to add a "const" to the "struct net_device *dev" argument and likewise update the dummy_ipv6_chk_addr() declaration. Signed-off-by: David S. Miller <davem@davemloft.net>

55 * For MIPS, we use KVM_SET_ONE_REG and KVM_GET_ONE_REG to access CP0
56 * registers. The id field is broken down as follows:
57 *
58 * bits[2..0] - Register 'sel' index.
59 * bits[7..3] - Register 'rd' index.
60 * bits[15..8] - Must be zero.
61 * bits[63..16] - 1 -> CP0 registers.
62 *
63 * Other sets registers may be added in the future. Each set would
64 * have its own identifier in bits[63..16].
65 *
66 * The addr field of struct kvm_one_reg must point to an aligned
67 * 64-bit wide location. For registers that are narrower than
68 * 64-bits, the value is stored in the low order bits of the location,
69 * and sign extended to 64-bits.
70 *
71 * The registers defined in struct kvm_regs are also accessible, the
72 * id values for these are below.
