3.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Seung-Woo Kim <sw0312.kim@samsung.com>

commit 5fdd1b56be51b1ec4dbde5b213d649ac717442da upstream.

The SRC_MFC register offset was incorrect, which could cause have caused
wrong calculation of rate of sclk_mfc clock, that could in turn lead to
incorrect operation of MFC. This patch corrects it.

From: "David S. Miller" <davem@davemloft.net>

[ Upstream commit aca5f58f9ba803ec8c2e6bcf890db17589e8dfcc ]

The VLAN tag handling code in netpoll_send_skb_on_dev() has two problems.

1) It exits without unlocking the TXQ.

2) It then tries to queue a NULL skb to npinfo->txq.

3.10-stable review patch. If anyone has any objections, please let me know.

------------------

From: Lan Tianyu <tianyu.lan@intel.com>

commit a90b40385735af0d3031f98e97b439e8944a31b3 upstream.

The AML method _BIX of NEC LZ750/LS returns a broken package which
skips the first member "Revision" (ACPI 5.0, Table 10-234).

Add a quirk for this machine to skip member "Revision" during parsing
the package returned by _BIX.
