x86/debug: Add KERN_<LEVEL> to bare printks, convert printks to pr_<level>
caused warn_bad_vsyscall to output garbage in the middle of the
line. Revert the bad part of it.
The printk in question isn't actually bare; the level is "%s".
The bug this fixes is purely cosmetic; backports are optional.

There's also a small collection of bug fixes that aren't critical
-rc worthy regressions because the consumer drivers aren't present
or using the buggy clocks and one optimization for HDMI.
This patch adds helper functions to configure clock parents and rates
as specified through 'assigned-clock-parents', 'assigned-clock-rates'
DT properties for a clock provider or clock consumer device.
The helpers are now being called by the bus code for the platform, I2C
and SPI busses, before the driver probing and also in the clock core
after registration of a clock provider.

and,
"One more fix - for a bug in the newly introduced code that obtains rate
control information for stations."
For the iwlwifi fixes, Emmanuel says:
"It includes a merge damage fix. This region has been changed in -next
and -fixes quite a few times and apparently, I failed to handle it
properly, so here the fix. Along with that I have a fix from Eliad
to properly handle overlapping BSS in AP mode."
On top of that, Felix provides and ath9k fix for Tx stalls that happen
after an aggregation session failure.

net: phy: Prevent an MDIO bus from being unloaded while in use
Changes from v1:
* Dropped the unneeded module_put() on phy_attach_direct().
The motivation of this small series is to fix the current lack of relationship
between an ethernet driver and the MDIO bus behind the PHY device. In such
cases, we would find no visible link between the drivers:
$ lsmod
Module Size Used by Not tainted
mvmdio 2941 0
mvneta 22069 0
Which means nothing prevents the MDIO driver from being removed:
$ modprobe -r mvmdio
# Unable to handle kernel NULL pointer dereference at virtual address 00000060
pgd = c0004000
[00000060] *pgd=00000000
Internal error: Oops: 17 [#1] SMP ARM
Modules linked in: mvneta [last unloaded: mvmdio]

PC is at phy_state_machine+0x1c/0x468
LR is at phy_state_machine+0x18/0x468
[snip]
This patchset fixes this problem by adding a pair of module_{get,put},
so the module reference count is increased when the PHY device is attached
and is decreased when the PHY is detached.
Tested with mvneta and mv643xx_eth drivers, which depend on the mvmdio
driver to handle MDIO. This series applies on both net and net-next branches.

mdiobus_register() registers a device which is already bound to a driver.
Hence, the driver pointer should be set properly in order to track down

This will be used to allow ethernet driver to pin down a MDIO bus driver,

This fix was necessary after
9c15a24b03 ("x86/mce: Improve mcheck_init_device() error handling")
went in. What this patch did was, among others, check the return value
of misc_register and exit early if it encountered an error. Original
code sloppily didn't do that.
However,
cef12ee52b ("xen/mce: Add mcelog support for Xen platform")
made it so that xen's init routine xen_late_init_mcelog runs first. This
was needed for the xen mcelog device which is supposed to be independent
from the baremetal one.
Initially it was reported that misc_register() fails often on xen and
that's why it needed fixing. However, it is *supposed* to fail by
design, when running in dom0 so that the xen mcelog device file gets
registered first.
And *then* you need the notifier *not* unregistered on the error path so
that the timer does get deleted properly in the CPU hotplug notifier.
Btw, this fix is needed also on baremetal in the unlikely event that
misc_register(&mce_chrdev_device) fails there too.
I was unsure whether to rush it in now and decided to delay it to 3.17.
However, xen people wanted it promoted as it breaks xen when doing cpu
hotplug there. So, after a bit of simmering in tip/master for initial
smoke testing, let's move it to 3.16. It fixes a semi-regression which
got introduced in 3.16 so no need for stable tagging.
tip/x86/ras contains that exact same commit but we can't remove it
there as it is not the last one. It won't cause any merge issues, as I
confirmed locally but I should state here the special situation of this
one fix explicitly anyway.
Thanks.
