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

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.

The justifications being automatic destruction of the vm instances
when no longer needed and more compact test naming under a common
class.
Besides those, a smaller test makes the one and only assertion rather
obvious, which suggests that we could even get rid of the more verbose
(and manual) error messages (to be decided).
Naming of the tests tries to follow the following pattern:
test_($cpu_version)_($no_arch_capabitilies_set_or_unset)_($machine_version)
The presence of each naming component is optional, depending on
whether the test manually sets it or not.

Note that this only works on Q35, the ACPI for PIIX4 is not capable

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.

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.)
