matthieu castet 82c01d3d5a V4L/DVB (5680): Tuner-simple.c fix suport for SECAM with FI1216MF
Allow to use SECAM-BG with the FI1216MF tuner.

The selection is done with the secam=B module argument.

The default behaviour should be the same as before.

Simon Arlott 4abdcf933f V4L/DVB (5630): Dvb-core: Handle failures to create devices
dvb-core is not started early enough when device drivers that use dvb are
compiled in so dvb_register_device fails (silently) since dvb_class is
NULL, this runs dvb_init using subsys_initcall instead of module_init.

dvb_register_device will now check the return value of class_device_create.

Hans Verkuil c74e83a863 V4L/DVB (5670): Adding new fields to v4l2_pix_format broke the ABI, reverted that change
Reverted the change to struct v4l2_pix_format. I completely missed that
this struct was used by existing ioctls so that changing it broke the ABI.
I will have to think of another way of setting the top/left coordinates
but for now this change is reverted to preserve compatibility.

This should make it stop immediately after printing the _helpful_ error

"netif_poll_enable can only be called if you've previously called
netif_poll_disable.  Otherwise a poll might already be in action
and you may get a crash like this."

Removing the call to netif_poll_enable in e1000_open should fix this issue,
the only other call to netif_poll_enable is in e1000_up() which is only
reached after a device reset or resume.

Michael S. Tsirkin 9f81036c54 IB/cm: Improve local id allocation
The IB CM uses an idr for local id allocations, with a running counter
as start_id.  This fails to generate distinct ids if

1. An id is constantly created and destroyed
2. A chunk of ids just beyond the current next_id value is occupied

This in turn leads to an increased chance of connection request being
mis-detected as a duplicate, sometimes for several retries, until
next_id gets past the block of allocated ids. This has been observed
in practice.

As a fix, remember the last id allocated and start immediately above it.
This also fixes a problem with the old code, where next_id might
overflow and become negative.

SRQ WR leakage has been observed with IPoIB/CM: e.g. flipping ports on

will start getting RNR NAKs.  Fix this in the way suggested by spec:
move the QP being destroyed to the error state, wait for "Last WQE
Reached" event and then post WR on a "drain QP" connected to the same
CQ.  Once we observe a completion on the drain QP, it's safe to call
ib_destroy_qp.

john stultz d0aff6e6f4 x86_64: vsyscall time() fix
The vsyscall time() function basically returns the second portion of
xtime directly.  This however means that there is about a ticks worth of
time each second where time() will return a second value less then what
gettimeofday() does.

Additionally, this window where vtime() is behind vgettimeofday() grows
when dynticks is enabled, so its probably good to get this in before
dynticks lands.

Big thanks to Sripathi for noticing this issue and creating a test case
to work with!

This patch changes the vtime() implemenation to call vgettimeofday(),
much as syscall time() implementation calls gettimeofday().

Yinghai Lu d8902bfcac x86_64: early_print kernel console should send CRLF not LFCR
In
	commit d358788f3f
	Author: Russell King <rmk@dyn-67.arm.linux.org.uk>
	Date:   Mon Mar 20 20:00:09 2006 +0000

Glen Turner reported that writing LFCR rather than the more
traditional CRLF causes issues with some terminals.

Since this afflicts many serial drivers, extract the common code to a
library function (uart_console_write) and arrange for each driver to
supply a "putchar" function.

but early_printk is left out.

Bernd Schmidt c824498db4 Blackfin arch: fix signal handling bug
There's a forum thread at
https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&_forum_action=MessageReply&message_id=24741

which has a testcase involving signal handling that crashes quite readily.
Inspecting the code I believe what happens is that signal handling can become
confused when it is invoked on return from an interrupt, if the contents of
P0 and R0 at the time of the interrupt happen to be such that P0 is larger
than zero (indicating to the signal code that we're in a syscall), and R0
happens to have a value of something like -EINTR or -ERESTARTSYS.
Fixed by setting orig_p0 to -1 if we're returning from an interrupt.  The
testcase now seems to run without problems.
