Ayaz Abdulla 001eb84bbf forcedeth: xmit lock fix
This patch fixes a potential race condition between xmit thread and xmit
completion thread. The calculation of empty tx descriptors is not
performed under the lock. This could cause it to set the stop flag while
the completion thread finishes all tx's. This will result in the tx
queue in stopped state and no one to wake it up.

Reported by Randy Dunlap http://marc.info/?l=linux-netdev&m=123147942302885&w=2

As well, escape the colon in the field's text description, as it is
causing the generated text to be erraticly broken up (with paragraphs
moved down). Could not find a reason why it is happening so, even when
other field descriptions use colons and work as expected.

Felix Fietkau 4ca857958c b44: fix misalignment and wasted space in rx handling
Broadcom 4400 puts a header of configurable size (apparently needs
to be at least 28 bytes) in front of received packets. When handling
this, the previous code accidentally added the offset 30 *twice* for
the software and once for the hardware, thereby cancelling out the
IP alignment effect of the 30 byte padding and wasting an additional
30 bytes of memory per packet.

This patch fixes this problem and improves routing throughput by
about 30% on MIPS, where unaligned access is expensive.

If you do

As always, implementing it in C is the correct thing to do.

While we're there, uninline it for size and possible header dependency
reasons.

And create a new kernel/up.c, as a place in which to put

Linus Torvalds 0176260fc3 btrfs: fix for write_super_lockfs/unlockfs error handling
Commit c4be0c1dc4 added the ability for
write_super_lockfs to return errors, and renamed them to match.  But
btrfs didn't get converted.

Do the minimal conversion to make it compile again.

Artem Bityutskiy f4b477c473 rbtree: add const qualifier to some functions
The 'rb_first()', 'rb_last()', 'rb_next()' and 'rb_prev()' calls
take a pointer to an RB node or RB root. They do not change the
pointed objects, so add a 'const' qualifier in order to make life
of the users of these functions easier.

Indeed, if I have my own constant pointer &const struct my_type *p,
and I call 'rb_next(&p->rb)', I get a GCC warning:

warning: passing argument 1 of ‘rb_next’ discards qualifiers from pointer target type

Eric Piel cfce41a6d6 LIS3LV02D: separate the core from HP ACPI API
The sensor can be accessed via various buses.  In particular, SPI, I²C
and, on HP laptops, via a specific ACPI API (the only one currently
supported).  Separate this latest platform from the core of the sensor
driver to allow support for the other bus type.  The second, and more
direct goal is actually to be able to merge this part with the
hp-disk-leds driver, which has the same ACPI PNP number.
