When this flag is set, we program the hardware to execute the flip
during horizontal blank (i.e. for the next scanline) instead of during
vertical blank (i.e. for the next frame).
Currently this is only supported on ASICs which have a page flip
completion interrupt (>= R600), and only if the use_pflipirq parameter
has value 2 (the default).

git://anongit.freedesktop.org/drm-intel into drm-next
Ofc I promise just a few leftovers for drm-misc and somehow it's the
biggest pull. But really mostly trivial stuff:
- MAINTAINERS updates from Emil
- rename async to nonblock in atomic_commit to avoid the confusion between
nonblocking ioctl and async flip (= not vblank synced), from Maarten.
Needs to be regened with newer drivers, but probably only after -rc1 to
catch them all.
- actually lockless gem_object_free, plus acked driver conversion patches.
All the trickier prep stuff already is in drm-next.
- Noralf's nice work for generic defio support in our fbdev emulation.
Keeps the udl hack, and qxl is tested by Gerd.

Regulators are optional for devices using OPPs and the OPP core
shouldn't be printing any errors for such missing regulators.
It was fine before the commit 0c717d0f9cb4, but that failed to update
this part of the code to remove an 'always true' check and an extra
unwanted print message.

Currently when performing random CPU hot-plugs and suspend-to-ram(S2R)
on systems using arm_big_little cpufreq driver, we get warnings similar
to something like below:
cpu cpu1: _opp_add: duplicate OPPs detected. Existing: freq: 600000000,
volt: 800000, enabled: 1. New: freq: 600000000, volt: 800000, enabled: 1
This is mainly because the OPPs for the shared cpus are not set. We can
just use dev_pm_opp_of_cpumask_add_table in case the OPPs are obtained
from DT(arm_big_little_dt.c) or use dev_pm_opp_set_sharing_cpus if the
OPPs are obtained by other means like firmware(e.g. scpi-cpufreq.c)
Also now that the generic dev_pm_opp{,_of}_cpumask_remove_table can
handle removal of opp table and entries for all associated CPUs, we can
re-use dev_pm_opp{,_of}_cpumask_remove_table as free_opp_table in
cpufreq_arm_bL_ops.
This patch makes necessary changes to reuse the generic OPP functions for
{init,free}_opp_table and thereby eliminating the warnings.

The new use of dev_pm_opp_set_sharing_cpus resulted in a harmless compiler
warning with CONFIG_CPUMASK_OFFSTACK=y:
drivers/cpufreq/mvebu-cpufreq.c: In function 'armada_xp_pmsu_cpufreq_init':
include/linux/cpumask.h:550:25: error: passing argument 2 of 'dev_pm_opp_set_sharing_cpus' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
The problem here is that cpumask_var_t gets passed by reference, but
by declaring a 'const cpumask_var_t' argument, only the pointer is
constant, not the actual mask. This is harmless because the function
does not actually modify the mask.
This patch changes the function prototypes for all of the related functions
to pass a 'struct cpumask *' instead of 'cpumask_var_t', matching what
most other such functions do in the kernel. This lets us mark all the
other similar functions as taking a 'const' mask where possible,
and it avoids the warning without any change in object code.

Currently, the userspace governor only updates frequency on GOV_LIMITS
if policy->cur falls outside policy->{min/max}. However, it is also
necessary to update current frequency on GOV_LIMITS to match the user
requested value if it can be achieved within the new policy->{max/min}.
This was previously the behaviour in the governor until commit d1922f0
("cpufreq: Simplify userspace governor") which incorrectly assumed that
policy->cur == user requested frequency via scaling_setspeed. This won't
be true if the user requested frequency falls outside policy->{min/max}.
Ex: a temporary thermal cap throttled the user requested frequency.
Fix this by storing the user requested frequency in a seperate variable.
The governor will then try to achieve this request on every GOV_LIMITS
change.

_OSI handling code grows giant and it's time to move them into one file.
This patch collects all _OSI handling code into one single file.
So that we only have the following functions to be used externally:
early_acpi_osi_init(): Used by DMI detections;
acpi_osi_init(): Used to initialize OSI command line settings and install
Linux specific _OSI handler;
acpi_osi_setup(): The API that should be used by the external quirks.
acpi_osi_is_win8(): The API is used by the external drivers to determine
if BIOS supports Win8.
CONFIG_DMI is not useful as stub dmi_check_system() can make everything
stub because of strip.

1. Change printk into pr_xxx
2. Do not initialize values to 0
3. Do not append additional "return" at the end of the function
4. Remove useless comments which may easily break line breaking rule
After fixing the coding style issues, rename functions to make them looking

The following commit always reports positive value when Apple hardware
queries _OSI("Darwin"):
Commit: 7bc5a2bad0b8d9d1ac9f7b8b33150e4ddf197334
Subject: ACPI: Support _OSI("Darwin") correctly
However since this implementation places the judgement in runtime, it
breaks acpi_osi=!Darwin and cannot return unsupported for _OSI("WinXXX")
invoked before invoking _OSI("Darwin").
This patch fixes the issues by reverting the wrong support and implementing
the default behavior of _OSI("Darwin")/_OSI("WinXXX") on Apple hardware via
DMI matching.

The order of the _OSI related functionalities is as follows:
acpi_blacklisted()
acpi_dmi_osi_linux()
acpi_osi_setup()
acpi_osi_setup()
acpi_update_interfaces() if "!*"
<<<<<<<<<<<<<<<<<<<<<<<<
parse_args()
__setup("acpi_osi=")
acpi_osi_setup_linux()
acpi_update_interfaces() if "!*"
<<<<<<<<<<<<<<<<<<<<<<<<
acpi_early_init()
acpi_initialize_subsystem()
acpi_ut_initialize_interfaces()
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
acpi_bus_init()
acpi_os_initialize1()
acpi_install_interface_handler(acpi_osi_handler)
acpi_osi_setup_late()
acpi_update_interfaces() for "!"
>>>>>>>>>>>>>>>>>>>>>>>>
acpi_osi_handler()
Since acpi_osi_setup_linux() can override acpi_dmi_osi_linux(), the command
line setting can override the DMI detection. That's why acpi_blacklisted()
is put before __setup("acpi_osi=").
Then we can notice the following wrong invocation order. There are
acpi_update_interfaces() (marked by <<<<) calls invoked before
acpi_ut_initialize_interfaces() (marked by ^^^^). This makes it impossible
to use acpi_osi=!* correctly from OSI DMI table or from the command line.
The use of acpi_osi=!* is meant to disable both ACPICA
(acpi_gbl_supported_interfaces) and Linux specific strings
(osi_setup_entries) while the ACPICA part should have stopped working
because of the order issue.
This patch fixes this issue by moving acpi_update_interfaces() to where
it is invoked for acpi_osi=! (marked by >>>>) as this is ensured to be
invoked after acpi_ut_initialize_interfaces() (marked by ^^^^). Linux
specific strings are still handled in the original place in order to make
the following command line working: acpi_osi=!* acpi_osi="Module Device".
Note that since acpi_osi=!* is meant to further disable linux specific
string comparing to the acpi_osi=!, there is no such use case in our bug
fixing work and hence there is no one using acpi_osi=!* either from the
command line or from the DMI quirks, this issue is just a theoretical
issue.

I'm trying to pass-through Broadcom BCM5720 NIC (Dell device 1f5b) on a
Dell R720 server. Everything works fine when the target VM has only one
CPU, but SMP guests reboot when the NIC driver accesses PCI config space
with hv_pcifront_read_config()/hv_pcifront_write_config(). The reboot
appears to be induced by the hypervisor and no crash is observed. Windows
event logs are not helpful at all ('Virtual machine ... has quit
unexpectedly'). The particular access point is always different and
putting debug between them (printk/mdelay/...) moves the issue further
away. The server model affects the issue as well: on Dell R420 I'm able to
pass-through BCM5720 NIC to SMP guests without issues.
While I'm obviously failing to reveal the essence of the issue I was able
to come up with a (possible) solution: if explicit barriers are added to
hv_pcifront_read_config()/hv_pcifront_write_config() the issue goes away.
The essential minimum is rmb() at the end on _hv_pcifront_read_config() and
wmb() at the end of _hv_pcifront_write_config() but I'm not confident it
will be sufficient for all hardware. I suggest the following barriers:
1) wmb()/mb() between choosing the function and writing to its space.
2) mb() before releasing the spinlock in both _hv_pcifront_read_config()/
_hv_pcifront_write_config() to ensure that consecutive reads/writes to
the space won't get re-ordered as drivers may count on that.
Config space access is not supposed to be performance-critical so these
explicit barriers should not cause any slowdown.

10GbE Intel Wired LAN Driver Updates 2016-05-04
This series contains updates to ixgbe, ixgbevf and traffic class helpers.
Sridhar adds helper functions to the tc_mirred header to access tcf_mirred
information and then implements them for ixgbe to enable redirection to
a SRIOV VF or an offloaded MACVLAN device queue via tc 'mirred' action.
Amritha adds support to set filters with multiple header fields (L3,L4)
to match on.
KY Srinivasan from Microsoft add Hyper-V support into ixgbevf.
Emil adds 82599 sub-device IDs that were missing from the list of parts
that support WoL. Then simplified the logic we use to determine WoL
support by reading the EEPROM bits for MACs X540 and newer.
Preethi cleaned up duplicate and unused device IDs. Fixed our ethtool
stat reporting where we were ignoring higher 32 bits of stats registers,
so fill out 64 bit stat values into two 32 bit words.
Babu Moger from Oracle improves VF performance issues on SPARC.
Alex Duyck cleans up some of the Hyper-V implementation from KY so that
we can just use function pointers instead of having to identify if a
given VF is running on a Linux or Windows PF.
Usha makes sure that DCB and FCoE is disabled for X550EM_x/a MACs and
cleans up the DCB initialization in the process.
Tony cleans up the API for ixgbevf_update_xcast_mode() so we do not
have to pass in the netdev parameter, since it was never used in the

The code determines if the next ring entry is valid before proceeding
further to read the rest of the entry. The CPU can re-order and read
the rest of the entry first, possibly reading a stale entry, if DMA
of a new entry happens right after reading it. This issue can be
readily seen on a ppc64 system, causing it to crash.
