Remove non-UAPI Kbuild files that have become empty as a result of UAPI
disintegration. They used to have only header-y lines in them and those have
now moved to the Kbuild files in the corresponding uapi/ directories.
Possibly these should not be removed but rather have a comment inserted to say
they are intentionally left blank. This would make it easier to add generated
header lines in future without having to restore the infrastructure.
Note that at this point not all the UAPI disintegration parts have been merged,
so it is likely that more empty Kbuild files will turn up.
It is probably necessary to make the files non-empty to prevent the patch
program from automatically deleting them when it reduces them to nothing.

uapi/linux/irqnr.h was emitted by the UAPI disintegration script as an empty
file because the parent linux/irqnr.h had no UAPI stuff in it, despite being
marked with "header-y".
Unfortunately, the patch program deletes the empty file when applying a kernel
patch.
It's not clear why this file is part of the UAPI at all. Looking in:
/usr/include/linux/irqnr.h
there's nothing there but a header reinclusion guard and a comment.
So just stick a comment in there as a placeholder.
Without this, if the kernel is fabricated from, say, a tarball and a patch, you
can get this error when building x86_64 or usermode Linux (and probably
others):
include/linux/irqnr.h:4:30: fatal error: uapi/linux/irqnr.h: No such file or directory

Drivers may need to iterate the active channel

that. To make it possible, use RCU-safe list
functions.
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
On each channel that the device is operating on, it
may need to listen using one or more chains depending
on the SMPS settings of the interfaces using it. The
previous channel context changes completely removed
this ability (before, it was available as the SMPS
mode).
Add per-context tracking of the required static and
dynamic RX chains and notify the driver on changes.
To achieve this, track the chains and SMPS mode used
on each virtual interface and update the channel
context whenever this changes.

Note that the fast_io field of struct regmap_bus is ignored in case
custom locking functions are used.

A task is considered frozen enough between freezer_do_not_count() and
freezer_count() and freezers use freezer_should_skip() to test this
condition. This supposedly works because freezer_count() always calls
try_to_freezer() after clearing %PF_FREEZER_SKIP.
However, there currently is nothing which guarantees that
freezer_count() sees %true freezing() after clearing %PF_FREEZER_SKIP
when freezing is in progress, and vice-versa. A task can escape the
freezing condition in effect by freezer_count() seeing !freezing() and
freezer_should_skip() seeing %PF_FREEZER_SKIP.
This patch adds smp_mb()'s to freezer_count() and
freezer_should_skip() such that either %true freezing() is visible to
freezer_count() or !PF_FREEZER_SKIP is visible to
freezer_should_skip().

cgroup core has a bug which violates a basic rule about event
notifications - when a new entity needs to be added, you add that to
the notification list first and then make the new entity conform to
the current state. If done in the reverse order, an event happening
inbetween will be lost.
cgroup_subsys->fork() is invoked way before the new task is added to
the css_set. Currently, cgroup_freezer is the only user of ->fork()
and uses it to make new tasks conform to the current state of the
freezer. If FROZEN state is requested while fork is in progress
between cgroup_fork_callbacks() and cgroup_post_fork(), the child
could escape freezing - the cgroup isn't frozen when ->fork() is
called and the freezer couldn't see the new task on the css_set.
This patch moves cgroup_subsys->fork() invocation to
cgroup_post_fork() after the new task is added to the css_set.
cgroup_fork_callbacks() is removed.
Because now a task may be migrated during cgroup_subsys->fork(),
freezer_fork() is updated so that it adheres to the usual RCU locking
and the rather pointless comment on why locking can be different there
is removed (if it doesn't make anything simpler, why even bother?).

A platform function pointer for getting the frequency of a OneNAND device
was added so that a platform could specify a custom function for returning
the frequency and not just rely on the OneNAND version to determine the
frequency. However, this platform function pointer is not currently being
used and I am not sure if it ever has.
OneNAND devices are not so common these days and as far as I know not being
used with new devices. Therefore, it is most likely that this get_freq()
function pointer will not be used and so remove it.
Given that the get_freq() function pointer is not used, neither is the
clk_dep variable and so all references to it can also be removed.
