5d74c8a065 ARM: EXYNOS: mark the DMA channel binding for SPI as preliminary
Bindings for DMA channels are still under discussion and will
change once this has been resolved. Therefore we mark them
the newly added ones as preliminary. Let's hope nobody starts
relying on them...

c540521bba security: Minor improvements to no_new_privs documentation
The documentation didn't actually mention how to enable no_new_privs.
This also adds a note about possible interactions between
no_new_privs and LSMs (i.e. why teaching systemd to set no_new_privs
is not necessarily a good idea), and it references the new docs
from include/linux/prctl.h.

c1cb438522 bindings: update imx and mxs #gpio-cells
The of_get_named_gpio_flags can retrieve the second cell of
gpio-specifier as the "flags".  The imx and mxs gpio driver do not
have their own .xlate callback, which means of_gpio_simple_xlate is
used and it's a 1:1 mapping between gpio controller flags and Linux
"enum of_gpio_flags".

Update imx and mxs bindings document to make it clear.

21f27291f5 Driver Core fixes for 3.5-rc5
Here is a number of printk() fixes, specifically a few reported by the
 crazy blog program that ships in SUSE releases (that's "boot log" and
 not "web log", it predates the general "blog" terminology by many
 years), and the restoration of the continuation line functionality
 reported by Stephen and others.  Yes, the changes seem a bit big this
 late in the cycle, but I've been beating on them for a while now, and
 Stephen has even optimized it a bit, so all looks good to me.
 
 The other change in here is a Documentation update for the stable kernel
 rules describing how some distro patches should be backported, to
 hopefully drive a bit more response from the distros to the stable
 kernel releases.

Merge tag 'driver-core-3.5-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver Core fixes from Greg Kroah-Hartman:
 "Here is a number of printk() fixes, specifically a few reported by the
  crazy blog program that ships in SUSE releases (that's "boot log" and
  not "web log", it predates the general "blog" terminology by many
  years), and the restoration of the continuation line functionality
  reported by Stephen and others.  Yes, the changes seem a bit big this
  late in the cycle, but I've been beating on them for a while now, and
  Stephen has even optimized it a bit, so all looks good to me.

  The other change in here is a Documentation update for the stable
  kernel rules describing how some distro patches should be backported,
  to hopefully drive a bit more response from the distros to the stable
  kernel releases.

eb3979f64d stable: Allow merging of backports for serious user-visible performance issues
Distribution kernel maintainers routinely backport fixes for users that
were deemed important but not "something critical" as defined by the
rules. To users of these kernels they are very serious and failing to fix
them reduces the value of -stable.

The problem is that the patches fixing these issues are often subtle and
prone to regressions in other ways and need greater care and attention.
To combat this, these "serious" backports should have a higher barrier
to entry.

This patch relaxes the rules to allow a distribution maintainer to merge
to -stable a backported patch or small series that fixes a "serious"
user-visible performance issue. They should include additional information on
the user-visible bug affected and a link to the bugzilla entry if available.
The same rules about the patch being already in mainline still apply.

bc259adc9b staging tree fixes for 3.5-rc4
Here are a number of small fixes for the drivers/staging tree, as well as iio
 and pstore drivers (which came from the staging tree in the 3.5-rc1 merge).
 All of these are tiny, but resolve issues that people have been reporting.
 
 There's also a documentation update to reflect what the iio drivers really are
 doing, which is good to get straightened out.
