tcp: speedup tcp_fixup_rcvbuf()
tcp_fixup_rcvbuf() contains a loop to estimate initial socket
rcv space needed for a given mss. With large MTU (like 64K on lo),
we can loop ~500 times and consume a lot of cpu cycles.

qlge: fix dma map leak when the last chunk is not allocated
qlge allocates chunks from a page that it maps and unmaps that page when
the last chunk is released. When the driver is unloaded or the card is
removed, all chunks are released and the page is unmapped for the last
chunk.
However, when the last chunk of a page is not allocated and the device
is removed, that page is not unmapped. In fact, its last reference is
not put and there's also a page leak. This bug prevents a device from
being properly hotplugged.
When the DMA API debug option is enabled, the following messages show
the pending DMA allocation after we remove the driver.
This patch fixes the bug by unmapping and putting the page from the ring
if its last chunk has not been allocated.

drm/mgag200: Fix writes into MGA1064_PIX_CLK_CTL register
The original line,
WREG_DAC(MGA1064_PIX_CLK_CTL_CLK_DIS, tmp);
wrote tmp into MGA1064_PIX_CLK_CTL_CLK_DIS, where
MGA1064_PIX_CLK_CTL_CLK_DIS is an offset into
MGA1064_PIX_CLK_CTL. Change the line to write properly into
MGA1064_PIX_CLK_CTL. There were other chunks of code nearby that use
the same pattern (but work correctly), so this patch updates them all
to use this new (slightly more efficient) write pattern. The WREG_DAC
macro was causing the DAC_INDEX register to be set to the same value
twice. WREG8(DAC_DATA, foo) takes advantage of the fact that DAC_INDEX
is already at the value we want.

emac: Fix EMAC soft reset on 460EX/GT
Fix EMAC soft reset on 460EX/GT to select the right PHY clock source
before and after the soft reset.
EMAC with PHY should use the clock from PHY during soft reset.
EMAC without PHY should use the internal clock during soft reset.
PPC460EX/GT Embedded Processor Advanced User's Manual
section 28.10.1 Mode Register 0 (EMACx_MR0) states:
Note: The PHY must provide a TX Clk in order to perform a soft reset
of the EMAC. If none is present, select the internal clock
(SDR0_ETH_CFG[EMACx_PHY_CLK] = 1).
After a soft reset, select the external clock.
Without the fix, 460EX/GT-based boards with RGMII PHYs attached to
EMACs experience EMAC interrupt storm and system watchdog reset when
issuing "ifconfig eth0 down" + "ifconfig eth0 up" a few times.
The system enters endless loop of serving emac_irq() with EMACx_ISR
register stuck at value 0x10000000 (Rx parity error).

I'm using following script to trigger this:
<script>
while [ 1 ]
do
ip link add link e1 name macvtap0 type macvtap mode passthru
ip link set e1 up
ip link set macvtap0 up
IFINDEX=`ip link |grep macvtap0 | cut -f 1 -d ':'`
cat /dev/tap$IFINDEX >/dev/null &
ip link del dev macvtap0
done
</script>
I run this script while "ping -f" is running on another machine to send
packets to e1 rx.
Reason of the panic is that list_first_entry() is blindly called in
macvlan_handle_frame() even if the list was empty. vlan is set to
incorrect pointer which leads to the crash.
I'm fixing this by protecting port->vlans list by rcu and by preventing
from getting incorrect pointer in case the list is empty.

drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo':
drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare]
Fix by eliminating one of them. The one kept is effectively the sas.h
one, but call it sas_device_type and make sure the enums are all
properly namespaced with the SAS_ prefix.
