If uio_register_device() fails in probe(), it breaks off initialization,

The current organization of Documentation/stable_kernel_rules.txt
doesn't clearly differentiate the mutually exclusive options for
submission to the -stable review process. As I understand it, patches
are not actually required to be mailed directly to
stable@vger.kernel.org, but the instructions do not make this clear.Also, there are some established processes that are not listed --
specifically, what I call Option 2 below.This patch updates and reorganizes a bit, to make things clearer.

The loop for measuring the square wave periods over some cycles is
refactored to be more easily readable. This includes avoiding a
"by-hand-implemented" for loop with a "real" one and adding some
comments.Furthermore the following compiler warning is avoided by this patch:
drivers/misc/ioc4.c: In function ‘ioc4_probe’:
drivers/misc/ioc4.c:194:16: warning: ‘start’ may be used uninitialized
in this function [-Wmaybe-uninitialized]

st_kim_ref() does not take care of the fact that platform_get_drvdata() might return NULL. On AM437x EVM, this causes the platform to stop booting as soon as the module is inserted.
This patch fixes the issue by checking for NULL return value. Oops log follows.
I have not tested BT functionality after this patch. But at least the platform boots now.

Modifying a non-existent slot is not allowed. Also check that the
first loop doesn't move a deleted slot beyond the used part of
the mslots array.Signed-off-by: Paolo Bonzini
-
Before commit 0e60b0799fed (kvm: change memslot sorting rule from size
to GFN, 2014-12-01), the memslots' sorting key was npages, meaning
that a valid memslot couldn't have its sorting key equal to zero.
On the other hand, a valid memslot can have base_gfn == 0, and invalid
memslots are identified by base_gfn == npages == 0.Because of this, commit 0e60b0799fed broke the invariant that invalid
memslots are at the end of the mslots array. When a memslot with
base_gfn == 0 was created, any invalid memslot before it were left
in place.This can be fixed by changing the insertion to use a ">=" comparison
instead of "

parisc: fix out-of-register compiler error in ldcw inline assembler function -
The __ldcw macro has a problem when its argument needs to be reloaded from
memory. The output memory operand and the input register operand both need to
be reloaded using a register in class R1_REGS when generating 64-bit code.
This fails because there's only a single register in the class. Instead, use a
memory clobber. This also makes the __ldcw macro a compiler memory barrier.Signed-off-by: John David Anglin

Implemented separate stream_tag assignment for input and output streams.
According to hda specification stream tag must be unique throughout the
input streams group, however an output stream might use a stream tag
which is already in use by an input stream. This change is necessary
to support HW which provides a total of more than 15 stream DMA engines
which with legacy implementation causes an overflow on SDxCTL.STRM
field (and the whole SDxCTL register) and as a result usage of
Reserved value 0 in the SDxCTL.STRM field which confuses HDA controller.Signed-off-by: Rafal Redzimski
