... and indicate cc=3 in case there is work remaining. Keep unicode

f1c2e27cb5 s390x/tcg: MVCL: Process max 4k bytes at a time
Process max 4k bytes at a time, writing back registers between the
accesses. The instruction is interruptible.
    "For operands longer than 2K bytes, access exceptions are not
    recognized for locations more than 2K bytes beyond the current location
    being processed."
Note that on z/Architecture, 2k vs. 4k access cannot get differentiated as
long as pages are not crossed. This seems to be a leftover from ESA/390.
Simply stay within single pages.

MVCL handling is quite different than MVCLE/MVCLU handling, so split up
the handlers.

Defer interrupt handling, as that will require more thought, add a TODO
for that.

7d69e8bc3b s390x/kvm: Officially require at least kernel 3.15
Since QEMU v2.10, the KVM acceleration does not work on older kernels
anymore since the code accidentally requires the KVM_CAP_DEVICE_CTRL
capability now - it should have been optional instead.
Instead of fixing the bug, we asked in the ChangeLog of QEMU 2.11 - 3.0
that people should speak up if they still need support of QEMU running
with KVM on older kernels, but seems like nobody really complained.
Thus let's make this official now and turn it into a proper error
message, telling the users to use at least kernel 3.15 now.

ebe15582ca pc: Add an SMB0 ACPI device to q35
This is so I2C devices can be found in the ACPI namespace.  Currently
that's only IPMI, but devices can be easily added now.

Adding the devices required some PCI information, and the bus itself
to be added to the PCMachineState structure.

Note that this only works on Q35, the ACPI for PIIX4 is not capable
of handling an SMBus device.

7b0cd78bf7 ipmi: Add a UUID device property
Using the UUID that qemu generates probably isn't the best thing
to do, allow it to be passed in via properties, and use QemuUUID
for the type.

If the UUID is not set, return an unsupported command error.  This
way we are not providing an all-zero (or randomly generated) GUID
to the IPMI user.  This lets the host fall back to the other
method of using the get device id command to determind the BMC
being accessed.

77cd44b9ec tests:ipmi: Fix IPMI BT tests
The IPMI BT tests had a race condition, if it receive an IPMI command
to enable interrupt, it would write the message to enable interrupts
after it wrote the command response.  So the test code could
receive the command response and issue the next command before the
device handled the interrupt enable command, and thus no interrupt.

So send the message to enable interrupt before the command response.

Also add some sleeps to give qemu time to handle responses, there was
no delay before, and it could result in an invalid timeout.

And re-enable the tests, as hopefully they are fixed now.

Note that I was unable to reproduce this even with the instructions
Peter gave me, but hopefully this fixes the issue.

b53c54c63f Makefile: Fix in-tree builds when Sphinx is available
In commit 27a296fce9 we switched the qemu-ga manpage over to
being built from Sphinx.  The makefile rules for this were correct
for an out-of-tree build, but break for in-tree builds if Sphinx is
present and we're trying to build the documentation.

Specifically, because Sphinx refuses to build output files into
the same directory as its sources, for an in-tree build we tell
it to build into a subdirectory docs/built, and set up a makefile
variable MANUAL_BUILDDIR indicating where the docs are going.
The makefile rule telling Make how to build qemu-ga.8 correctly
used this variable, but the lines adding qemu-ga.8 to the list
of DOCS to be built and the 'make install' rune did not. The
effect was that for an in-tree build we told Make to build
'docs/interop/qemu-ga.8' but did not provide a specific rule for
doing so, which caused Make to fall back to the old rules.make
rule for building any "%.8" file. Make tried to invoke texi2pod
with a bogus command line, resulting in the error:

  GEN     docs/interop/qemu-ga.8
No filename or title
make: *** [rules.mak:394: docs/interop/qemu-ga.8]

Fix this by using $(MANUAL_BUILDDIR) when constructing the
list of DOCS files we want to build and also in the source
file name we install for 'make install'.

(Among other things, this broke the Shippable CI builds.)

471c97a693 BootLinuxSshTest: Only run the tests when explicitly requested
Currently the Avocado framework does not distinct the time spent
downloading assets vs. the time spent running a test. With big
assets (like a full VM image) the tests likely fail.

This is a limitation known by the Avocado team.
Until this issue get fixed, do not run this tests automatically.

Tests can still be run setting the AVOCADO_TIMEOUT_EXPECTED
environment variable.

7cc0cdcd6a RISC-V Patches for the 4.2 Soft Freeze, Part 1, v3
This contains quite a few patches that I'd like to target for 4.2.
 They're mostly emulation fixes for the sifive_u board, which now much
 more closely matches the hardware and can therefor run the same fireware
 as what gets loaded onto the board.  Additional user-visible
 improvements include:
 
 * support for loading initrd files from the command line into Linux, via
   /chosen/linux,initrd-{start,end} device tree nodes.
 * The conversion of LOG_TRACE to trace events.
 * The addition of clock DT nodes for our uart and ethernet.
 
 This also includes some preliminary work for the H extension patches,
 but does not include the H extension patches as I haven't had time to
 review them yet.
 
 This passes my OE boot test on 32-bit and 64-bit virt machines, as well
 as a 64-bit upstream Linux boot on the sifive_u machine.  It has been
 fixed to actually pass "make check" this time.
 
 Changes since v2 (never made it to the list):
 
 * Sets the sifive_u machine default core count to 2 instead of 5.
 
 Changes since v1 <20190910190513.21160-1-palmer@sifive.com>:
 
 * Sets the sifive_u machine default core count to 5 instead of 1, as
   it's impossible to have a single core sifive_u machine.

198d7003f1 target/m68k/fpu_helper.c: rename the access arguments
The "access" arguments clash with a macro under Windows with MinGW:

  target/m68k/fpu_helper.c: In function 'fmovem_predec':

   but takes just 2
               size = access(env, addr, &env->fregs[i], ra);

So this renames them access_fn.

976e8c5414 Replace '-machine accel=xyz' with '-accel xyz'
We've got a separate option to configure the accelerator nowadays, which
is shorter to type and the preferred way of specifying an accelerator.
Use it in the source and examples to show that it is the favored option.
(However, do not touch the places yet which also specify other machine
options or multiple accelerators - these are currently still better
handled with one single "-machine" statement instead)
