Soft mmu uses direct shadow page to fill guest large mapping with small
pages if huge mapping is disallowed on host. So zapping direct shadow
page works well both for soft mmu and hard mmu, it's just less widely
applicable.

As Andres pointed out:
| I don't understand the value of this check here. Are we looking for a
| broken memslot? Shouldn't this be a BUG_ON? Is this the place to care
| about these things? npages is capped to KVM_MEM_MAX_NR_PAGES, i.e.
| 2^31. A 64 bit overflow would be caused by a gigantic gfn_start which
| would be trouble in many other ways.
This patch drops the memslot overflow check to make the codes more simple.

Commit 27356f54c8c3 ("mm/hotplug: verify hotplug memory range")
introduced a check that makes add_memory() only accept section size
aligned memory.
Therefore on z/VM systems, where standby memory is not aligned, no
standby memory is registered at all.
Example:
#cp def store 3504M standby 2336M
00: CP Q V STORE
00: STORAGE = 3504M MAX = 6G INC = 8M STANDBY = 2336M RESERVED = 0
For this setup the following error message is printed:
Section-unaligned hotplug range: start 0xdb000000, size 0x92000000
So fix this and register aligned memory in "sclp_cmd.c". This means
that for the corner cases where the standby memory is not aligned we
loose some memory.
In order to inform the user about the potential loss of standby memory,
we add a new message for each added standby block and print how
much of the standby memory is usable, for example:
sclp_cmd.4336b4: Standby memory at 0x50000000 (256M of 256M usable)
sclp_cmd.4336b4: Standby memory at 0xb0000000 (256M of 256M usable)
sclp_cmd.4336b4: Standby memory at 0xdb000000 (2048M of 2336M usable)
We also ensure that a potential memory block that contains both "assigned"
and "standby" memory cannot be setup offline.

If the device being added to Xen is not contained in the ACPI table,
walk the PCI device tree to find a parent that is contained in the ACPI
table before finding the PXM information from this device.
Previously, it would try to get a handle for the device, then the
device's bridge, then the physfn. This changes the order so that it
tries to get a handle for the device, then the physfn, the walks up the

Originally Xen PV drivers only use single-page ring to pass along
information. This might limit the throughput between frontend and
backend.
The patch extends Xenbus driver to support multi-page ring, which in
general should improve throughput if ring is the bottleneck. Changes to
various frontend / backend to adapt to the new interface are also
included.
Affected Xen drivers:
* blkfront/back
* netfront/back
* pcifront/back
* scsifront/back
* vtpmfront
The interface is documented, as before, in xenbus_client.c.

Pull ARM updates from Russell King:
"Included in this update are both some long term fixes and some new
features.
Fixes:
- An integer overflow in the calculation of ELF_ET_DYN_BASE.
- Avoiding OOMs for high-order IOMMU allocations
- SMP requires the data cache to be enabled for synchronisation
primitives to work, so prevent the CPU_DCACHE_DISABLE option being
visible on SMP builds.
- A bug going back 10+ years in the noMMU ARM94* CPU support code,
where it corrupts registers. Found by folk getting Linux running
on their cameras.
- Versatile Express needs an errata workaround enabled for CPU
hot-unplug to work.
Features:
- Clean up module linker by handling out of range relocations
separately from relocation cases we don't handle.
- Fix a long term bug in the pci_mmap_page_range() code, which we
hope won't impact userspace (we hope there's no users of the
existing broken interface.)
- Don't map DMA coherent allocations when we don't have a MMU.
- Drop experimental status for SMP_ON_UP.
- Warn when DT doesn't specify ePAPR mandatory cache properties.
- Add documentation concerning how we find the start of physical
memory for AUTO_ZRELADDR kernels, detailing why we have chosen the
mask and the implications of changing it.
- Updates from Ard Biesheuvel to address some issues with large
kernels (such as allyesconfig) failing to link.
- Allow hibernation to work on modern (ARMv7) CPUs - this appears to
have never worked in the past on these CPUs.
- Enable IRQ_SHOW_LEVEL, which changes the /proc/interrupts output
format (hopefully without userspace breaking... let's hope that if
it causes someone a problem, they tell us.)
- Fix tegra-ahb DT offsets.
- Rework ARM errata 643719 code (and ARMv7 flush_cache_louis()/
flush_dcache_all()) code to be more efficient, and enable this
errata workaround by default for ARMv7+SMP CPUs. This complements
the Versatile Express fix above.
- Rework ARMv7 context code for errata 430973, so that only Cortex A8
CPUs are impacted by the branch target buffer flush when this
errata is enabled. Also update the help text to indicate that all
r1p* A8 CPUs are impacted.
- Switch ARM to the generic show_mem() implementation, it conveys all
the information which we were already reporting.
- Prevent slow timer sources being used for udelay() - timers running
at less than 1MHz are not useful for this, and can cause udelay()
to return immediately, without any wait. Using such a slow timer
is silly.
- VDSO support for 32-bit ARM, mainly for gettimeofday() using the
ARM architected timer.
- Perf support for Scorpion performance monitoring units"
vdso semantic conflict fixed up as per linux-next.

- ACPI backlight driver update including a new mechanism to allow
native backlight handling to be forced on non-Windows 8 systems and
a new quirk for Lenovo Ideapad Z570 (Aaron Lu, Hans de Goede)

- gk20a iommu support
- gm107 graphics support without needing proprietary ucode
- various random fixes
- more gm20x bring-up, fifo/ce are ok, gr is mostly complete with the
exception of ctxsw ucode.. nvidia aren't playing nice yet so there's
not much more that can be done at this point...
I spent a lot of time trying to find a viable way of doing gr ctxsw
without signed firmware, but the "security" restrictions on the
fecs/gpccs falcons are excessive and go beyond what'd be necessary to
protect the host from malicious firmware. This newer nvidia hw is
VERY open-source unfriendly.
I have some experimental host-based ctxsw work that could be a viable
(albeit unsatisfactory and slow) workaround in the meantime, but it
needs some more work and i'd like to get the 3d driver working
properly before i commit to pushing it.

Intel Wired LAN Driver Updates 2015-04-14
This series contains updates to fm10k only.
Fixed transmit statistics which was actually using values from the
receive ring, instead of the transmit ring. Fixed up spelling mistakes
in code comments and resolved unused argument warnings. Added support
for netconsole. Fixed up statistic reporting so that we are only
reporting from actual queues as well as display PF only stats for
just the PF and not the VF. Also fixed an issue that when returning
virtualization queues from the VF back to the PF, we were retaining
the VF rate limiter.
Fixed up the driver to use a separate workqueue, which helps reduce
and stabilize latency between scheduling the work in our interrupt and
actually performing the work.
Fixed a bug where the VF tried to set a multicast address before
requesting the required xcast mode.
Fix VF multicast update since VFs were being improperly added to the
switch's mutlicast group. The error stems from the fact that incorrect
arguments were passed to the update_mc_addr().
Thanks to Alex Duyck for the extensive review.

It is reported that ACPI interrupts do not work any more on
Dell Latitude D600 after commit c50f13c672df (ACPICA: Save
current masks of enabled GPEs after enable register writes).
The problem turns out to be related to the fact that the
enable_mask and enable_for_run GPE bit masks are not in
sync (in the absence of any system suspend/resume events)
for at least one GPE register on that machine.
Address this problem by writing the enable_for_run mask into
enable_mask as soon as enable_for_run is updated instead of
doing that only after the subsequent register write has
succeeded. For consistency, update acpi_hw_gpe_enable_write()
to store the bit mask to be written into the GPE register
in enable_mask unconditionally before the write.
Since the ACPI_GPE_SAVE_MASK flag is not necessary any more after
that, drop it along with the symbols depending on it.
