x86/boot/smp: Don't try to poke disabled/non-existent APIC
Apparently trying to poke a disabled or non-existent APIC
leads to a box that doesn't even boot. Let's not do that.
No real clue if this is the right fix, but at least my
P3 machine boots again.

arm/arm64: KVM: Map the BSS at HYP
When used with a compiler that doesn't implement "asm goto"
(such as the AArch64 port of GCC 4.8), jump labels generate a
memory access to find out about the value of the key (instead
of just patching the code). The key itself is likely to be
stored in the BSS.
This is perfectly fine, except that we don't map the BSS at HYP,
leading to an exploding kernel at the first access. The obvious
fix is simply to map the BSS there (which should have been done
a long while ago, but hey...).

arm64: KVM: Take S1 walks into account when determining S2 write faults
The WnR bit in the HSR/ESR_EL2 indicates whether a data abort was
generated by a read or a write instruction. For stage 2 data aborts
generated by a stage 1 translation table walk (i.e. the actual page
table access faults at EL2), the WnR bit therefore reports whether the
instruction generating the walk was a load or a store, *not* whether the
page table walker was reading or writing the entry.
For page tables marked as read-only at stage 2 (e.g. due to KSM merging
them with the tables from another guest), this could result in livelock,
where a page table walk generated by a load instruction attempts to
set the access flag in the stage 1 descriptor, but fails to trigger
CoW in the host since only a read fault is reported.
This patch modifies the arm64 kvm_vcpu_dabt_iswrite function to
take into account stage 2 faults in stage 1 walks. Since DBM cannot be
disabled at EL2 for CPUs that implement it, we assume that these faults
are always causes by writes, avoiding the livelock situation at the
expense of occasional, spurious CoWs.
We could, in theory, do a bit better by checking the guest TCR
configuration and inspecting the page table to see why the PTE faulted.
However, I doubt this is measurable in practice, and the threat of
livelock is real.

drm/i915: Clean up DDI DDC/AUX CH sanitation
Now that we use the AUX and GMBUS assignment from VBT for all ports,
let's clean up the sanitization of the port information a bit.
Previosuly we only did this for port E, and only complained about a
non-standard assignment for the other ports. But as we know that
non-standard assignments are a fact of life, let's expand the

clocksource: Add J-Core timer/clocksource driver
At the hardware level, the J-Core PIT is integrated with the interrupt
controller, but it is represented as its own device and has an
independent programming interface. It provides a 12-bit countdown
timer, which is not presently used, and a periodic timer. The interval
length for the latter is programmable via a 32-bit throttle register
whose units are determined by a bus-period register. The periodic
timer is used to implement both periodic and oneshot clock event
modes; in oneshot mode the interrupt handler simply disables the timer
as soon as it fires.
Despite its device tree node representing an interrupt for the PIT,
the actual irq generated is programmable, not hard-wired. The driver
is responsible for programming the PIT to generate the hardware irq
number that the DT assigns to it.
On SMP configurations, J-Core provides cpu-local instances of the PIT;
no broadcast timer is needed. This driver supports the creation of the
necessary per-cpu clock_event_device instances.
A nanosecond-resolution clocksource is provided using the J-Core "RTC"
registers, which give a 64-bit seconds count and 32-bit nanoseconds
that wrap every second. The driver converts these to a full-range
32-bit nanoseconds count.

KVM: s390: reject invalid modes for runtime instrumentation
Usually a validity intercept is a programming error of the host
because of invalid entries in the state description.
We can get a validity intercept if the mode of the runtime
instrumentation control block is wrong. As the host does not know
which modes are valid, this can be used by userspace to trigger
a WARN.
Instead of printing a WARN let's return an error to userspace as
this can only happen if userspace provides a malformed initial
value (e.g. on migration). The kernel should never warn on bogus
input. Instead let's log it into the s390 debug feature.
While at it, let's return -EINVAL for all validity intercepts as
this will trigger an error in QEMU like

Merge tag 'mmc-v4.9-rc1' of git://git./linux/kernel/git/ulfh/mmc
Pull MMC fixes from Ulf Hansson:
"Here are some mmc fixes intended for v4.9 rc2.
This time I have also included a few changes for a memstick driver
which has a corresponding mmc driver. They use the same USB device as
parent, hence both needs to play nice with runtime PM, which they
didn't.
MMC core:
- Update MAINTAINERS as the mmc tree moved to kernel.org
- A few fixes for HS400es mode
- A few other minor fixes
MMC host:
- sdhci: Fix an issue when dealing with stop commands
- sdhci-pci: Fix a bus power failure issue
- sdhci-esdhc-imx: Correct two register accesses
- sdhci-of-arasan: Fix the 1.8V I/O signal switch behaviour
- rtsx_usb_sdmmc: Fix runtime PM issues
Other: (Because of no maintainer)
- memstick: rtsx_usb_ms: Fix runtime PM issues"
