Jiri Kosina 23d386d85a HID: fixup Kconfig entry for Roccat Kone
Make it independent on CONFIG_EMBEDDED (to be in sync with other
"full-fledged" HID drivers which are not simple quirks) and provide
a little bit better text description.

Stefan Achatz 14bf62cde7 HID: add driver for Roccat Kone gaming mouse
This Patch adds support for Kone gaming mouse from Roccat.
It provides access to profiles, settings, firmware, weight,
actual settings etc. through sysfs attributes.
Event handling of this mouse differs from standard hid behaviour
in that tilt button press is reported in each move event which
results in strange behaviour if not handled by the driver.

This is a heavily reworked version of the previously introduced driver.
The changes include most of the previously raised concerns,
memory leak and other fixes, code cleanups, adoption of additional
achieved knowlege about the hardware and is (IMHO) a much better version
than before even when I exchanged reduced USB-IO with a bigger memory
consumption.

I refused to implement one mentioned point:
Removing the 'just-because-we-can' attributes. Motivation:
Reading the clipped in weight: I'm no gamer and can't determine the
usefulness of this feature but if the manufacturer implements such a
feature it might make sense to someone and I would unwillingly limit the
functionality besides its such a small feature.
Reading the actual profile and dpi settings: Here I can testify that one
can get lost of the actual settings when switching back and forth.
The manufacturers windows driver has the ability for on-screen-display
of the values and there is a mouse in the market that has an lcd on the
underside of it to show these values. So I think this feature makes sense
not only for me and shouldn't be removed.

Heiko Carstens 57b552ba0b memory hotplug/s390: set phys_device
Implement arch specific arch_get_memory_phys_device function and
initialize phys_device for each memory section.  That way we finally can
tell which piece of memory belongs to which physical device.

This makes s390's /sys/devices/system/memory/memoryX/phys_device display
the correct thing?

Heiko Carstens bc32df0089 memory hotplug: allow setting of phys_device
/sys/devices/system/memory/memoryX/phys_device is supposed to contain the
number of the physical device that the corresponding piece of memory
belongs to.

In case a physical device should be replaced or taken offline for whatever
reason it is necessary to set all corresponding memory pieces offline.
The current implementation always sets phys_device to '0' and there is no
way or hook to change that.  Seems like there was a plan to implement that
but it wasn't finished for whatever reason.

So add a weak function which architectures can override to actually set
the phys_device from within add_memory_block().

James Chapman c3259c8a70 l2tp: Fix UDP socket reference count bugs in the pppol2tp driver
This patch fixes UDP socket refcnt bugs in the pppol2tp driver.

A bug can cause a kernel stack trace when a tunnel socket is closed.

A way to reproduce the issue is to prepare the UDP socket for L2TP (by
opening a tunnel pppol2tp socket) and then close it before any L2TP
sessions are added to it. The sequence is

Create UDP socket
Create tunnel pppol2tp socket to prepare UDP socket for L2TP
  pppol2tp_connect: session_id=0, peer_session_id=0
L2TP SCCRP control frame received (tunnel_id==0)
  pppol2tp_recv_core: sock_hold()
  pppol2tp_recv_core: sock_put
L2TP ZLB control frame received (tunnel_id=nnn)
  pppol2tp_recv_core: sock_hold()
  pppol2tp_recv_core: sock_put
Close tunnel management socket
  pppol2tp_release: session_id=0, peer_session_id=0
Close UDP socket
  udp_lib_close: BUG

The addition of sock_hold() in pppol2tp_connect() solves the problem.

For data frames, two sock_put() calls were added to plug a refcnt leak
per received data frame. The ref that is grabbed at the top of
pppol2tp_recv_core() must always be released, but this wasn't done for
accepted data frames or data frames discarded because of bad UDP
checksums. This leak meant that any UDP socket that had passed L2TP
data traffic (i.e. L2TP data frames, not just L2TP control frames)
using pppol2tp would not be released by the kernel.

Florian Fainelli 14b5d6dd40 leds: Fix race between LED device uevent and actual attributes creation
If we were to dynamically register/unregister leds and have udev or other
daemons handle the leds class uevents, we would be notified of the adding of a
new LED and if the daemon immediately tries to open one of the attributes of
the led device, it would fail with a "no such file or directory" error since
this the attributes are not yet created. Fix this by switching attributes to be
class-wide, such that the driver core will register these attributes with
device_add_attrs and then emit the kobject_uevent ADD signal.

Anton Vorontsov 0493a4ff10 leds-gpio: fix default state handling on OF platforms
The driver wrongly sets default state for LEDs that don't specify
default-state property.

Currently the driver handles default state this way:

memset(&led, 0, sizeof(led));
for_each_child_of_node(np, child) {
	state = of_get_property(child, "default-state", NULL);
	if (state) {
		if (!strcmp(state, "keep"))
			led.default_state = LEDS_GPIO_DEFSTATE_KEEP;
		...
	}
	ret = create_gpio_led(&led, ...);
}

Which means that all LEDs that do not specify default-state will inherit
the last value of the default-state property, which is wrong.

This patch fixes the issue by moving LED's template initialization into
the loop body.

When dumping /sys/kernel/debug/hid/$device/events '\0' characters show up
(invisible if cat to console but shown by less or while looking at a dump
 file).  These are due to hid_debug_event() adding strlen()+1 bytes to the ring
buffer (e.g. including the trailing '\0').  Any roll-over causes a '\0' as well
as hid_debug_event() handles the ring buffers with HID_DEBUG_BUFSIZE-1 size
while hid_debug_events_read() handles it with full HID_DEBUG_BUFSIZE size.

SAB82532_ISR0_TCD is declared in drivers/serial/subsab.h as relating to a
status register, while SAB82532_IMR0_TCD is declared in the same file as
relating to a mask register.  The latter seems more appropriate for the
interrupt_mask0 field, and follows the strategy for initializing this field
elsewhere in the same file.

Both SAB82532_ISR0_TCD and SAB82532_IMR0_TCD have the same value.

NeilBrown 627a2d3c29 md: deal with merge_bvec_fn in component devices better.
If a component device has a merge_bvec_fn then as we never call it
we must ensure we never need to.  Currently this is done by setting
max_sector to 1 PAGE, however this does not stop a bio being created
with several sub-page iovecs that would violate the merge_bvec_fn.

So instead set max_segments to 1 and set the segment boundary to the
same as a page boundary to ensure there is only ever one single-page
segment of IO requested at a time.

This can particularly be an issue when 'xen' is used as it is
known to submit multiple small buffers in a single bio.
