git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/defconfig
i.MX defconfig updates for 4.10:
- Increase CMA size to 64 MiB, so that we can use etnaviv driver with
1920x1080 display devices.
- Enable ES8328 codec driver support, which is required by Kosagi
Novena boards.

The Integrators are now migrated to handle the CPUfreq
scaling using the generic devicetree CPUfreq driver using the
common clock framework and have the required device tree
modifications, so turn off the old driver and turn on the new
generic driver.

KVM/ARM updates for 4.9-rc2
- Handle faults generated by the page table walker as being writes
- Map the BSS at EL2
|
|
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...).

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.

Although I am leaving Synopsys, I would like to keep working with the linux

sending this patch to change my contact e-mail.

The TPS65217 driver grew interrupt support which uses
irq_set_parent(). While it's not yet clear why this is used in the first
place, building the driver as a module fails with:
ERROR: ".irq_set_parent" [drivers/mfd/tps65217.ko] undefined!
The correctness of the driver change is still investigated, but for now
it's less trouble to export irq_set_parent() than dealing with the build
wreckage.
[ tglx: Rewrote changelog and made the export GPL ]
Fixes: 6556bdacf646 ("mfd: tps65217: Add support for IRQs")

The libfc stack assigns exchange IDs based on the CPU the request
was received on, so we need to send the responses via the same CPU.
Otherwise the send logic gets confuses and responses will be delayed,
causing exchange timeouts on the initiator side.
