Since 4.3 introduced devm_memremap_pages() the pfns handled by DAX may
optionally have a struct page backing. When a mapped pfn reaches
vmf_insert_pfn_pmd() it fails with a crash signature like the following:
kernel BUG at mm/huge_memory.c:905!
[..]
Call Trace:
[<ffffffff812a73ba>] __dax_pmd_fault+0x2ea/0x5b0
[<ffffffffa01a4182>] xfs_filemap_pmd_fault+0x92/0x150 [xfs]
[<ffffffff811fbe02>] handle_mm_fault+0x312/0x1b50
Fix this by falling back to 4K mappings in the pfn_valid() case. Longer
term, vmf_insert_pfn_pmd() needs to grow support for architectures that
can provide a 'pmd_special' capability.

wasn't called
Seems the crtc helpers call drm_calc_timestamping_constants()
unconditionally even if the driver didn't initialize vblank support by
calling drm_vblank_init(). That used to be OK since the constants were
stored under drm_crtc.
However I broke this with
commit eba1f35dfe14 ("drm: Move timestamping constants into drm_vblank_crtc")
when I moved the constants to live inside the drm_vblank_crtc struct
instead. If drm_vblank_init() isn't called, we don't allocate these
structures, and so drm_calc_timestamping_constants() will oops.
Fix it by adding a check into drm_calc_timestamping_constants() to see
if vblank support was initialized at all. And to keep in line with other
such checks, also toss in a check and warn for the case where vblank
support was initialized, but the wrong number of crtcs was specified.
Fixes the following sort of oops:

exit to the host either.

AMD, the patches mostly move things from there to common
arch/x86/kvm/ code.
- generic: remove local_irq_save/restore from the guest entry and
exit paths when context tracking is enabled. The patches are a few
months old, but we discussed them again at kernel summit. Andy

Normally symbols are read from the DSO and adjusted, if need be, so that
the symbol start matches the file offset in the DSO file (we want the
file offset because that is what we know from MMAP events). That is done
by dso__load_sym() which inserts the symbols *after* adjusting them.
In the case of kcore, the symbols have been read from kallsyms and the
symbol start is the memory address. The symbols have to be adjusted to
match the kcore file offsets. dso__split_kallsyms_for_kcore() does that,
but now the adjustment is being done *after* the symbols have been
inserted. It appears dso__split_kallsyms_for_kcore() was assuming that
changing the symbol start would not change the order in the rbtree -
which is, of course, not guaranteed.

logical OR of multiple different types. In particular, we have
and unsigned long
QSGMII_PHY_CDR_EN == BIT(0) == (1ul << 0) == 0x0000000000000001ul
and a signed int
0xC << QSGMII_PHY_TX_DRV_AMP_OFFSET == 0xc0000000
which together gives a signed long value
0xffffffffc0000001l
and when this is passed into a function that takes an unsigned int type,
gcc warns about the signed overflow and the loss of the upper 32-bits that
are all ones.
This patch adds 'ul' type modifiers to the literal numbers passed in
here, so now the expression remains an 'unsigned long' with the upper
bits all zero, and that avoids the signed overflow and the warning.

There are several sound drivers that 'select ZONE_DMA'. This is
backwards as ZONE_DMA is an architecture capability exported to drivers.
Switch the polarity of the dependency to disable these drivers when the
architecture does not support ZONE_DMA. This was discovered in the
context of testing/enabling devm_memremap_pages() which depends on
ZONE_DEVICE. ZONE_DEVICE in turn depends on !ZONE_DMA.

Pull more power management and ACPI updates from Rafael Wysocki:
"The only new feature in this batch is support for the ACPI _CCA device
configuration object, which it a pre-requisite for future ACPI PCI
support on ARM64, but should not affect the other architectures.
The rest is fixes and cleanups, mostly in cpufreq (including
intel_pstate), the Operating Performace Points (OPP) framework and
tools (cpupower and turbostat).
Specifics:
- Support for the ACPI _CCA configuration object intended to tell the
OS whether or not a bus master device supports hardware managed
cache coherency and a new set of functions to allow drivers to
check the cache coherency support for devices in a platform
firmware interface agnostic way (Suravee Suthikulpanit, Jeremy
Linton).
- ACPI backlight quirks for ESPRIMO Mobile M9410 and Dell XPS L421X
(Aaron Lu, Hans de Goede).
- Fixes for the arm_big_little and s5pv210-cpufreq cpufreq drivers
(Jon Medhurst, Nicolas Pitre).
- kfree()-related fixup for the recently introduced CPPC cpufreq
frontend (Markus Elfring).
- intel_pstate fix reducing kernel log noise on systems where
P-states are managed by hardware (Prarit Bhargava).
- intel_pstate maintainers information update (Srinivas Pandruvada).
- cpufreq core optimization related to the handling of delayed work
items used by governors (Viresh Kumar).
- Locking fixes and cleanups of the Operating Performance Points
(OPP) framework (Viresh Kumar).
- Generic power domains framework cleanups (Lina Iyer).
- cpupower tool updates (Jacob Tanenbaum, Sriram Raghunathan, Thomas
Renninger).
- turbostat tool updates (Len Brown)"

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree. This
large batch that includes fixes for ipset, netfilter ingress, nf_tables
dynamic set instantiation and a longstanding Kconfig dependency problem.
More specifically, they are:
1) Add missing check for empty hook list at the ingress hook, from
Florian Westphal.
2) Input and output interface are swapped at the ingress hook,
reported by Patrick McHardy.
3) Resolve ipset extension alignment issues on ARM, patch from Jozsef
Kadlecsik.
4) Fix bit check on bitmap in ipset hash type, also from Jozsef.
5) Release buckets when all entries have expired in ipset hash type,
again from Jozsef.
6) Oneliner to initialize conntrack tuple object in the PPTP helper,
otherwise the conntrack lookup may fail due to random bits in the
structure holes, patch from Anthony Lineham.
7) Silence a bogus gcc warning in nfnetlink_log, from Arnd Bergmann.
8) Fix Kconfig dependency problems with TPROXY, socket and dup, also
from Arnd.
9) Add __netdev_alloc_pcpu_stats() to allow creating percpu counters
from atomic context, this is required by the follow up fix for
nf_tables.
10) Fix crash from the dynamic set expression, we have to add new clone
operation that should be defined when a simple memcpy is not enough.
This resolves a crash when using per-cpu counters with new Patrick
McHardy's flow table nft support.

This marks the function as __maybe_unused, so the compiler knows that

The HDMI codec parser may create a phantom jack, but the helper
function snd_hda_jack_add_kctl() treats always as a normal jack. This
is superfluous as the jack query is executed at each time the jack
sync is performed.
Since the HDMI codec parser is the only caller of this function, it's
easier to change back this directly calling the original
__snd_hda_jack_add_kctl() with phantom_jack parameter.
