Compile tested.
remove unnecessary code that matches this coccinelle pattern

	ret = phy_write(x, y , z)
	if (ret < 0)
	       	return ret;

As phy_write returns error code, we dont need to do not need extra check
before returning.

net/hyperv: Add flow control based on hi/low watermark · 33be96e4

Haiyang Zhang authored Mar 27, 2012

In the existing code, we only stop queue when the ringbuffer is full,
so the current packet has to be dropped or retried from upper layer.

This patch stops the tx queue when available ringbuffer is below
the low watermark. So the ringbuffer still has small amount of space
available for the current packet. This will reduce the overhead of
retries on sending.

sky2: fix missing register reset on error path in sky2_test_msi() · ede7193d

Lino Sanfilippo authored Mar 30, 2012

In sky2_test_msi() the temporarily set SW IRQ in B0 register is not reset in case
that request_irq() fails.
With this patch we only set the interrupt mask if request_irq() was successful.

af_unix: reduce high order page allocations · eb6a2481

Eric Dumazet authored Apr 03, 2012

unix_dgram_sendmsg() currently builds linear skbs, and this can stress
page allocator with high order page allocations. When memory gets
fragmented, this can eventually fail.

We can try to use order-2 allocations for skb head (SKB_MAX_ALLOC) plus
up to 16 page fragments to lower pressure on buddy allocator.

This patch has no effect on messages of less than 16064 bytes.
(on 64bit arches with PAGE_SIZE=4096)

For bigger messages (from 16065 to 81600 bytes), this patch brings
reliability at the expense of performance penalty because of extra pages
allocations.

net: Report dev->promiscuity in netlink reports. · edbc0bb3

Ben Greear authored Mar 29, 2012

The standard ways of probing a device's promiscuity
(ifi_flags, for instance) does not report the actual
state of the device.  This patch adds dev->promiscuity
to the netlink netdevice report so that users can know
for certain if the device is acting PROMISC or not.
