   - fix a section naming error - ".init.text" rather than ".text.init"
   - preallocate DMA debug memory at core_initcall() time rather than
     fs_initcall(), as we have some core drivers that need to use DMA

With the new (in 4.9) option to use a virtually-mapped stack
(CONFIG_VMAP_STACK), stack buffers cannot be used as input/output for
the scatterlist crypto API because they may not be directly mappable to
struct page.  get_crypt_info() was using a stack buffer to hold the
output from the encryption operation used to derive the per-file key.
Fix it by using a heap buffer.

This bug could most easily be observed in a CONFIG_DEBUG_SG kernel
because this allowed the BUG in sg_set_buf() to be triggered.

The reason is that kvm_put_kvm is causing the destruction of the VM, but
the page fault is still on the ->queue list.  The ->queue list is owned
by the VCPU, not by the work items, so we cannot just add list_del to
the work item.

Instead, use work->vcpu to note async page faults that have been resolved
and will be processed through the done list.  There is no need to flush
those.

  Summary:

     many users just unconditionally rely on it to be available. And it

Recently algif_hash has been changed to allow null hashes.  This
triggers a bug when used with an shash algorithm whereby it will
cause a crash during the digest operation.

This patch fixes it by avoiding the digest operation and instead
doing an init followed by a final which avoids the buggy code in
shash.

This patch also ensures that the result buffer is freed after an
error so that it is not returned as a genuine hash result on the
next recv call.

The shash/ahash wrapper code will be fixed later to handle this
case correctly.

KVM calls kvm_pmu_set_counter_event_type() when PMCCFILTR is configured.
But this function can't deals with PMCCFILTR correctly because the evtCount
bits of PMCCFILTR, which is reserved 0, conflits with the SW_INCR event
type of other PMXEVTYPER<n> registers. To fix it, when eventsel == 0, this
function shouldn't return immediately; instead it needs to check further
if select_idx is ARMV8_PMU_CYCLE_IDX.

Another issue is that KVM shouldn't copy the eventsel bits of PMCCFILTER
blindly to attr.config. Instead it ought to convert the request to the
"cpu cycle" event type (i.e. 0x11).

To support this patch and to prevent duplicated definitions, a limited
set of ARMv8 perf event types were relocated from perf_event.c to
asm/perf_event.h.

We're missing the handling code for the cycle counter accessed
from a 32bit guest, leading to unexpected results.

On POWER9 DD1, when we do a local TLB invalidate we also need to explicitly
invalidate the ERAT.

since clk_prepare_enable() is used to get i2c->clk, we should
use clk_disable_unprepare() to release it for the error path.

Allwinner fixes for 4.9

A fix to reintroduce missing pinmux options that turned out not to be
optional.

i.MX fixes for 4.9, 2nd round:

It fixes a boot failure on imx53-qsb board with a DA9053 PMIC, which is
caused by the regulator core change, commit fa93fd4e ("regulator:
core: Ensure we are at least in bounds for our constraints").

Merge tag 'omap-for-v4.9/fixes-for-rc-cycle' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

Fixes for omaps for v4.9-rc cycle. Except for the omap3 fix for the SoC
features printed, all these are quite trivial and tiny. The omap5 jack
detection and gpadc patches are not strictly fixes, but I wanted to get
binding document typo fixed before it pops up on other boards. The
gpadc one liner was in the same series and I applied and pushed it out
already before noticing it could have waited. The list of changes is:

- Fix omap3 SoC features printed
- Make sure OMAP_INTERCONNECT is selected for am43xx only configurations
- Add missing memory node for torpedo
- Initialize uart4_mask properly to avoid writing garbage to PRM registers
- Fix NULL pointer dereference for omap4 volt_data
- Add alias for omap5 gpadc needed by iio drivers
- Enable omap5 jack headset jack detection and fix it's binding typo
- Add missing memory node for logicpd-som-lv
- Fix wrong SMPS6 voltage for VDD-DDR3 for omap5
