Several drivers need font support independent of CONFIG_VT, cfr. commit
9cbce8d7e1dae0744ca4f68d62aa7de18196b6f4, "console/font: Refactor font
support code selection logic").
Hence move the fonts and their support logic from drivers/video/console/ to
its own library directory lib/fonts/.
This also allows to limit processing of drivers/video/console/Makefile to
CONFIG_VT=y again.

Commit 9ddec56131 (cifs: move handling of signed connections into
separate function) broke signing on SMB2/3 connections. While the code
to enable signing on the connections was very similar between the two,
the bits that get set in the sec_mode are different.
Declare a couple of new smb_version_values fields and set them
appropriately for SMB1 and SMB2/3. Then change cifs_enable_signing to
use those instead.

1672d04070 ("cgroup: fix cgroupfs_root early destruction path")
introduced CGRP_ROOT_SUBSYS_BOUND which is used to mark completion of
subsys binding on a new root; however, this broke remounts.
cgroup_remount() doesn't allow changing root options via remount and
CGRP_ROOT_SUBSYS_BOUND, which is set on all fully initialized roots,
makes the function reject all remounts.
Fix it by putting the options part in the lower 16 bits of root->flags
and masking the comparions. While at it, make cgroup_remount() emit
an error message explaining why it's rejecting a remount request, so
that it's less of a mystery.

commit f8f7d63fd96ead101415a1302035137a866f8998 ("powerpc/eeh: Trace eeh
device from I/O cache") broke EEH on pseries for devices that were
present during boot and have not been hotplugged/DLPARed.
eeh_check_failure will get the eeh_dev from the cache, and will get
NULL. eeh_addr_cache_build adds the addresses to the cache, but eeh_dev
for the giving pci_device is not set yet. Just reordering the call to
eeh_addr_cache_insert_dev works fine. The ordering is similar to the one
in eeh_add_device_late.

git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/late
From David Brown:
MSM clock updates for 3.11.
Per Stephen Boyd's coverletter:
Resending to collect higher level maintainer acks per Olof's request.
The plan is to push this patchset through MSM to the arm-soc tree.
This patchset moves the existing MSM clock code and affected drivers
to the common clock framework. A prerequisite of moving to the common
clock framework is to use clk_prepare() and clk_enable() so the first
few patches migrate drivers to that call (clk_prepare() is a no-op on
MSM right now). It also removes some custom clock APIs that MSM
provides and finally moves the proc_comm clock code to the common
struct clk.
This patch series will be used as the foundation of the MSM 8660/8960
clock code that I plan to send out after this series.

pm_trace uses the system's Real Time Clock (RTC) to save the magic
number. The reason for this is that the RTC is the only reliably
available piece of hardware during resume operations where a value
can be set that will survive a reboot.
Consequence is that after a resume (even if it is successful) your
system clock will have a value corresponding to the magic number
instead of the correct date/time! It is therefore advisable to use
a program like ntp-date or rdate to reset the correct date/time from
an external time source when using this trace option.
There is no run-time message to warn users of the consequences of
enabling pm_trace. Adding a warning message to pm_trace_store()
will serve as a reminder to users to set the system date and time
after resume.

The Roland Quad/Octo-Capture devices use some unknown vendor-specific
mechanism to switch sample rates (and to manage other controls). To
prevent the driver from attempting to use any other than the default
44.1 kHz sample rate, use quirks to hide the other alternate settings.

snd_card_register() registers all devices newly added since the last
call. However, the playback/capture streams are handled as one ALSA
device, so the second /dev device will not be registered if the PCM
streams are added in two steps.
QUIRK_AUTODETECT caused the probe callback to be called once for each
interface, which triggered this problem. Work around this by handling
this like the composite quirk, i.e., autodetecting all other interfaces
that might be used for PCM or MIDI.

Commits fcf8058 (cpufreq: Simplify cpufreq_add_dev()) and aa77a52
(cpufreq: acpi-cpufreq: Don't set policy->related_cpus from .init())
changed the contents of the "related_cpus" sysfs attribute on systems
where acpi-cpufreq is used and user space can't get the list of CPUs
which are in the same hardware coordination CPU domain (provided by
the ACPI AML method _PSD) via "related_cpus" any more.
To make up for that loss add a new sysfs attribute "freqdomian_cpus"
for the acpi-cpufreq driver which exposes the list of CPUs in the
same domain regardless of whether it is coordinated by hardware or
software.

Whenever we are changing frequency of a cpu, we are calling PRECHANGE and
POSTCHANGE notifiers. They must be serialized. i.e. PRECHANGE or POSTCHANGE
shouldn't be called twice contiguously.
This can happen due to bugs in users of __cpufreq_driver_target() or actual
cpufreq drivers who are sending these notifiers.
This patch adds some protection against this. Now, we keep track of the last
transaction and see if something went wrong.

ACPI Timer() opcode should return monotonically increasing clock with 100ns
granularity according the ACPI 5.0 spec.
Testing the current Timer() implementation with following ASL code (and an
additional debug print in acpi_os_sleep() to get the sleep times dumped out
to dmesg):
// Test: 10ms
Store(Timer, Local1)
Sleep(10)
Divide(Subtract(Timer, Local1), 10000,, Local1)
Sleep(Local1)
// Test: 200ms
Store(Timer, Local1)
Sleep(200)
Divide(Subtract(Timer, Local1), 10000,, Local1)
Sleep(Local1)
// Test 1300ms
Store(Timer, Local1)
Sleep(1300)
Divide(Subtract(Timer, Local1), 10000,, Local1)
Sleep(Local1)
The second sleep value is calculated using Timer(). If the implementation
is good enough we should be able to get the second value pretty close to
the first.
However, the current Timer() gives pretty bad sleep times:
[ 11.488100] ACPI: acpi_os_get_timer() TBD
[ 11.492150] ACPI: Sleep(10)
[ 11.502993] ACPI: Sleep(0)
[ 11.506315] ACPI: Sleep(200)
[ 11.706237] ACPI: Sleep(0)
[ 11.709550] ACPI: Sleep(1300)
[ 13.008929] ACPI: Sleep(0)
Fix this with the help of ktime_get(). Once the fix is applied and run
against the same ASL code we get:
[ 11.486786] ACPI: Sleep(10)
[ 11.499029] ACPI: Sleep(12)
[ 11.512350] ACPI: Sleep(200)
[ 11.712282] ACPI: Sleep(200)
[ 11.912170] ACPI: Sleep(1300)
[ 13.211577] ACPI: Sleep(1300)
That is much more closer to the values we expected.

On HP Folio 13-2000, the BIOS defines a CMOS RTC Operation Region and
the EC's _REG methord accesses that region. Thus an appropriate
address space handler must be registered for that region before the
EC driver is loaded.
Introduce a mechanism for adding CMOS RTC address space handlers.
Register an ACPI scan handler for CMOS RTC devices such that, when
a device of that kind is detected during an ACPI namespace scan, a
common CMOS RTC operation region address space handler will be
installed for it.

Due to a lack of device and vendor identification registers, the
Dallas/Maxim DS16xx devices cannot be uniquely detected, sometimes
resulting in false positives. Therefore, the detect function is
being removed in favor of explicit device instantiation.

The ds1721 device can be configured for 9..12 bit resolutions;
add a sysfs attribute for userspace to configure this attribute.
The definition, description, details, and usage are shown in the
documentation and were crafted from an LM73 driver patch done by
Chris Verges & Guenter Roeck).

If a GFS2 file system is mounted with quotas and a file is grown
in such a way that its free blocks for the allocation are represented
in a secondary bitmap, GFS2 ran out of blocks in the transaction.
That resulted in "fatal: assertion "tr->tr_num_buf <= tr->tr_blocks".
This patch reserves extra blocks for the quota change so the
transaction has enough space.
