If we use growth_mode = metadata, it is very much possible that the file
uses more disk space after we have written something to the added area.
We did indeed want to test for this case, but unfortunately we evidently
just copied the code from the "Test creation preallocation" section and
forgot to replace "$create_mode" by "$growth_mode".

We never noticed because we only read the first number from qemu-img
info's "disk size" output -- and that is effectively useless, because
qemu-img prints a human-readable value (which generally includes a
decimal point).  That will be fixed in the patch after the next one.

The difference is that we don't call scsi_disk_req_check_error() before

the request is cancelled, however it shouldn't get canceled until it

Each block_acct_done/failed call is designed to correspond to a
previous block_acct_start call, which initializes the stats cookie.
However sometimes it is not the case, e.g. some error paths might
report the same cookie twice because it is hard to accurately track if
the cookie was reported yet or not.

This patch cleans the cookie after report.
(Note: block_acct_failed/done without a previous block_acct_start at
all should be avoided. Uninitialized cookie might hold a garbage value
and there is still "< BLOCK_MAX_IOTYPE" assertion for that)

It will be particularly useful in ide code where it's hard to
keep track whether the request done its accounting or not: in the
following patch of the series, trim requests will do the accounting
separately.

Notes:

1. As BlockCopyState keeps own BlockBackend objects, remaining
job->common.blk users only use it to get bs by blk_bs() call, so clear
job->commen.blk permissions set in block_job_create and add
job->source_bs to be used instead of blk_bs(job->common.blk), to keep
it more clear which bs we use when introduce backup-top filter in
further commit.

2. Rename s/initializing_bitmap/skip_unallocated/ to sound a bit better
as interface to BlockCopyState

3. Split is not very clean: there left some duplicated fields, backup
code uses some BlockCopyState fields directly, let's postpone it for
further improvements and keep this comment simpler for review.

Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

Launching the destination VM before the source VM gives us a regression
test for HEAD^:

The guest device causes a read from the disk image through
guess_disk_lchs().  This will not work if the first sector (containing
the partition table) is yet unallocated, we use COR, and the node is
inactive.

By launching the source VM before the destination, however, the COR
filter on the source will allocate that area in the image shared between
both VMs, thus the problem will not become apparent.

Switching the launch order causes the sector to still be unallocated
when guess_disk_lchs() runs on the inactive node in the destination VM,
and thus we get our test case.

It turns out that forcing python2 for running the edk2 "build" utility is
neither necessary nor sufficient.

Forcing python2 is not sufficient for two reasons:

- QEMU is moving away from python2, with python2 nearing EOL,

- according to my most recent testing, the lacking dependency information
  in the makefiles that are generated by edk2's "build" utility can cause
  parallel build failures even when "build" is executed by python2.

And forcing python2 is not necessary because we can still return to the
original idea of filtering out jobserver-related options from MAKEFLAGS.
So do that.

While at it, cut short edk2's auto-detection of the python3.* minor
version, by setting PYTHON_COMMAND to "python3" (which we expect to be
available wherever we intend to build edk2).

With this patch, the guest UEFI binaries that are used as part of the BIOS
tables test, and the OVMF and ArmVirtQemu platform firmwares, will be
built strictly in a single job, regardless of an outermost "-jN" make
option. Alas, there appears to be no reliable way to build edk2 in an
(outer make, inner make) environment, with a jobserver enabled.

Currently the `make efi` target pulls submodules nested under the
roms/edk2 submodule as dependencies. However, when we attempt to build
from a tarball this fails since we are no longer in a git tree.

A preceding patch will pre-populate these submodules in the tarball,
so assume this build dependency is only needed when building from a
git tree.

The `make efi` target added by 536d2173 is built from the roms/edk2
submodule, which in turn relies on additional submodules nested under
roms/edk2.

The make-release script currently only pulls in top-level submodules,
so these nested submodules are missing in the resulting tarball.

We could try to address this situation more generally by recursively
pulling in all submodules, but this doesn't necessarily ensure the
end-result will build properly (this case also required other changes).

Additionally, due to the nature of submodules, we may not always have
control over how these sorts of things are dealt with, so for now we
continue to handle it on a case-by-case in the make-release script.

ppc patch queue 2019-10-04

Here's the next batch of ppc and spapr patches.  Includes:
  * Fist part of a large cleanup to irq infrastructure
  * Recreate the full FDT at CAS time, instead of making a difficult
    to follow set of updates.  This will help us move towards
    eliminating CAS reboots altogether
  * No longer provide RTAS blob to SLOF - SLOF can include it just as
    well itself, since guests will generally need to relocate it with
    a call to instantiate-rtas
  * A number of DFP fixes and cleanups from Mark Cave-Ayland
  * Assorted bugfixes
  * Several new small devices for powernv
