Both of these options are poorly named. The features they provide are
necessary for system security and should not be considered debug only.
Change the names to CONFIG_STRICT_KERNEL_RWX and
CONFIG_STRICT_MODULE_RWX to better describe what these options do.

The current code uses the CLOCKSOURCE_OF_DECLARE macro to fill the clksrc
table with a t-uple (name, init_function).
Unfortunately it ends up to the clockevent and the clocksource being
both initialized with this macro. It is not a problem by itself but there
is not a clear distinction between a clockevent and a clocksource in the
code initialization path. Somebody can argue there are the same IP block
and the same DT node. But conceptually from the software side, there are
two distincts entities and as is they should be initialized separetely.
Some drivers which do not have a clocksource end up by using the
CLOCKSOURCE_OF_DECLARE macro to declare a clockevent.
Another result is the fuzzy organization in the clocksource directory,
where the clockevents are implemented in the same file than the
clocksources or file labelled timer-something implementing a clocksource.
This patch provides another macro to specifically declare a clockevent in
the same way than the clocksource and gives the opportunity to write two
separate drivers, one for the clocksource and another for the clockevents.
Hopefully, that can help to do some housework in the directory, perhaps
split the drivers in to entities, for example:
- clksrc-rockchip.c
- clkevt-rockchip.c
Also, it gives the possibility to declare clocksources separately in the
DT and then use a clocksource from IP block while while clockevents are
used from another IP block.

__packed is considered harmful as it potentially generates code that
doesn't perform well and its usage should be avoided as much as
possible.
This patch drops __packed from all SCTP structures except one, which is
sctp_signed_cookie. In there it's required, as per changelog on
commit 9834a2bb4970 ("[SCTP]: Fix sctp_cookie alignment in the packet.").
After this patch, no alignment changes neither in x86 or x86_64 and
no exceptions were noticed during testing on both archs.
Code size for SCTP module also didn't change with this patch.

Saeed Mahameed says:
====================
mlx5-updates-2017-01-31
This series includes some updates to mlx5 core and ethernet driver.
We got one patch from Or to fix some static checker warnings.
2nd patche from Dan came to add the support for 128B cache line
in the HCA, which will configures the hardware to use 128B alignment only
on systems with 128B cache lines, otherwise it will be kept as the current
default of 64B.
From me three patches to support no inline copy on TX on ConnectX-5 and
later HCAs. Starting with two small infrastructure changes and
refactoring patches followed by two patches to add the actual support for
both xmit ndo and XDP xmit routines.
Last patch is a simple fix to return a mistakenly removed pointer from the
SQ structure, which was remove in previous submission of mlx5 4K UAR.

git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc into HEAD
The big feature this time is support for POWER9 using the radix-tree
MMU for host and guest. This required some changes to arch/powerpc
code, so I talked with Michael Ellerman and he created a topic branch
with this patchset, which I merged into kvm-ppc-next and which Michael
will pull into his tree. Michael also put in some patches from Nick
Piggin which fix bugs in the interrupt vector code in relocatable
kernels when coming from a KVM guest.
Other notable changes include:
* Add the ability to change the size of the hashed page table,
from David Gibson.
* XICS (interrupt controller) emulation fixes and improvements,
from Li Zhong.
* Bug fixes from myself and Thomas Huth.
These patches define some new KVM capabilities and ioctls, but there
should be no conflicts with anything else currently upstream, as far
as I am aware.

Allow drivers to use the new DSA API with platform data. Most of the
code in net/dsa/dsa2.c does not rely so much on device_nodes and can get
the same information from platform_data instead.
We purposely do not support distributed configurations with platform
data, so drivers should be providing a pointer to a 'struct
dsa_chip_data' structure if they wish to communicate per-port layout.
Multiple CPUs port could potentially be supported and dsa_chip_data is
extended to receive up to one reference to an upstream network device
per port described by a dsa_chip_data structure.
dsa_dev_to_net_device() increments the network device's reference count,
so we intentionally call dev_put() to be consistent with the DT-enabled
path, until we have a generic notifier based solution.

For XDP we will need to reset the queues to allow for buffer headroom
to be configured. In order to do this we need to essentially run the
freeze()/restore() code path. Unfortunately the locking requirements
between the freeze/restore and reset paths are different however so
we can not simply reuse the code.
This patch refactors the code path and adds a reset helper routine.

Get the firmware's secure-boot status in the kernel boot wrapper and stash
it somewhere that the main kernel image can find.
The efi_get_secureboot() function is extracted from the ARM stub and (a)
generalised so that it can be called from x86 and (b) made to use
efi_call_runtime() so that it can be run in mixed-mode.
For x86, it is stored in boot_params and can be overridden by the boot
loader or kexec. This allows secure-boot mode to be passed on to a new

list of #defines had to be updated in every filesystem whenever a change
was made to the public fscrypt functions. To make things more
maintainable now that we have three filesystems using fscrypt, split the
old header fscrypto.h into several new headers. fscrypt_supp.h contains
the real declarations and is included by filesystems when configured
with encryption support, whereas fscrypt_notsupp.h contains the inline
stubs and is included by filesystems when configured without encryption
support. fscrypt_common.h contains common declarations needed by both.

Move the document describing the system sleep state transitions API
for devices to Documentation/driver-api/pm/, convert it to reST and
update it to use current terminology. Also remove the remaining
reference to the old version of it from pm.h.
The new document still contains references to some documents in the
.txt format that will be converted later.

Refresh the struct dev_pm_ops kerneldoc comment, so that it looks
better and is more readable after processing by Sphinx, and drop
the kerneldoc marker from a few other comments ("PM_EVENT_ messages"
and a couple of enum types declarations) which are not proper
kerneldoc and generally confuse Sphinx.
Also change the comment describing struct dev_pm_domain into
a kerneldoc one.
