In the SMMU_STRTAB_BASE register, the stream table base address only

out to obtain the base address.
The branch for 2-level stream tables correctly applies this mask by way
of SMMU_BASE_ADDR_MASK, but the one for linear stream tables does not.
Apply the missing mask in that case as well so that the correct stream
base address is used by guests which configure a linear stream table.
Linux guests are unaffected by this change because they choose a 2-level
stream table layout for the QEMU SMMUv3, based on the size of its stream
ID space.

target/arm: Prepare generic timer for per-platform CNTFRQ
The ASPEED AST2600 clocks the generic timer at the rate of HPLL. On
recent firmwares this is at 1125MHz, which is considerably quicker than
the assumed 62.5MHz of the current generic timer implementation. The
delta between the value as read from CNTFRQ and the true rate of the
underlying QEMUTimer leads to sticky behaviour in AST2600 guests.
Add a feature-gated property exposing CNTFRQ for ARM CPUs providing the
generic timer. This allows platforms to configure CNTFRQ (and the
associated QEMUTimer) to the appropriate frequency prior to starting the
guest.
As the platform can now determine the rate of CNTFRQ we're exposed to
limitations of QEMUTimer that didn't previously materialise: In the
course of emulation we need to arbitrarily and accurately convert
between guest ticks and time, but we're constrained by QEMUTimer's use
of an integer scaling factor. The effect is QEMUTimer cannot exactly
capture the period of frequencies that do not cleanly divide
NANOSECONDS_PER_SECOND for scaling ticks to time. As such, provide an
equally inaccurate scaling factor for scaling time to ticks so at least
a self-consistent inverse relationship holds.

target/arm: Abstract the generic timer frequency
Prepare for SoCs such as the ASPEED AST2600 whose firmware configures
CNTFRQ to values significantly larger than the static 62.5MHz value
currently derived from GTIMER_SCALE. As the OS potentially derives its
timer periods from the CNTFRQ value the lack of support for running
QEMUTimers at the appropriate rate leads to sticky behaviour in the
guest.
Substitute the GTIMER_SCALE constant with use of a helper to derive the
period from gt_cntfrq_hz stored in struct ARMCPU. Initially set
gt_cntfrq_hz to the frequency associated with GTIMER_SCALE so current
behaviour is maintained.

block: Activate recursively even for already active nodes
bdrv_invalidate_cache_all() assumes that all nodes in a given subtree
are either active or inactive when it starts. Therefore, as soon as it
arrives at an already active node, it stops.
However, this assumption is wrong. For example, it's possible to take a
snapshot of an inactive node, which results in an active overlay over an
inactive backing file. The active overlay is probably also the root node
of an inactive BlockBackend (blk->disable_perm == true).
In this case, bdrv_invalidate_cache_all() does not need to do anything
to activate the overlay node, but it still needs to recurse into the
children and the parents to make sure that after returning success,
really everything is activated.

travis.yml: Remove the redundant clang-with-MAIN_SOFTMMU_TARGETS entry
We test clang with the MAIN_SOFTMMU_TARGETS twice, once without

since if compilation and tests succeeded with sanitizers enabled, it
should also work fine without sanitizers. Thus remove the clang entry
without sanitizers to speed up the CI testing a little bit.

Add use of RCU for qemu_logfile.
This now allows changing the logfile while logging is active,
and also solves the issue of a seg fault while changing the logfile.
Any read access to the qemu_logfile handle will use
the rcu_read_lock()/unlock() around the use of the handle.
To fetch the handle we will use atomic_rcu_read().
We also in many cases do a check for validity of the
logfile handle before using it to deal with the case where the
file is closed and set to NULL.
The cases where we write to the qemu_logfile will use atomic_rcu_set().

tests/boot-sector: Fix the bad s390x assembler code
There are currently two bugs in s390x_code[]: First, the initial jump
uses the wrong offset, so it was jumping to 0x10014 instead of 0x10010.
Second, LHI only loads the lower 32-bit of the register.
Everything worked fine as long as the s390-ccw bios code was jumping
here with r3 containing zeroes in the uppermost 48 bit - which just
happened to be the case so far by accident. But we can not rely on this
fact, and indeed one of the recent suggested patches to jump2ipl.c cause
the newer GCCs to put different values into r3. In that case the code
from s390x_code[] crashes very ungracefully.

instead of LHI to make sure that we always zero out the upper bits
of the register.

iotests: Fix timeout in run_job()
run_job() accepts a wait parameter for a timeout, but it doesn't
actually use it. The only thing that is missing is passing it to
events_wait(), so do that now.

qcow2: Declare BDRV_REQ_NO_FALLBACK supported
In the common case, qcow2_co_pwrite_zeroes() already only modifies
metadata case, so we're fine with or without BDRV_REQ_NO_FALLBACK set.
The only exception is when using an external data file, where the
request is passed down to the block driver of the external data file. We
are forwarding the BDRV_REQ_NO_FALLBACK flag there, though, so this is
fine, too.
Declare the flag supported therefore.

blockjob: Fix error message for negative speed
The error message for a negative speed uses QERR_INVALID_PARAMETER,
which implies that the 'speed' option doesn't even exist:
{"error": {"class": "GenericError", "desc": "Invalid parameter 'speed'"}}
Make it use QERR_INVALID_PARAMETER_VALUE instead:
{"error": {"class": "GenericError", "desc": "Parameter 'speed' expects a non-negative value"}}

block: Error out on image creation with conflicting size options
If both the create options (qemu-img create -o ...) and the size

make specifying two sizes an error.

qemu-img: fix info --backing-chain --image-opts
Only apply --image-opts to the topmost image when listing an entire

t.IMGFMT.mid <- t.IMGFMT, qemu-img info fails as follows:
