With PCREL, we have a page-relative view of EIP, and an
approximation of PC = EIP+CSBASE that is good enough to
detect page crossings. If we try to recompute PC after
masking EIP, we will mess up that approximation and write
a corrupt value to EIP.
We already handled masking properly for PCREL, so the
fix in b5e0d5d2 was only needed for the !PCREL path.

In 8.2, the upstream added graph lock annotations that conflict with
our coroutine patches. The GRAPH_RDLOCK_GUARD_MAINLOOP is now asserted
at some places where we turned the code into a coroutine.
My understanding is that the annotation merely asserts that the code
is running in the main loop and serves effectively as a marker of
where the graph lock should be taken if the code were to be moved out
of the main loop. That's exactly what we're doing so it should be safe
to replace the main loop check with an actual rdlock/rdunlock pair.
Commits e7e801a2a7, 94d03a7425 and c89144c058 replace
GRAPH_RDLOCK_GUARD_MAINLOOP() with GRAPH_RDLOCK_GUARD() at the
bdrv_snapshot_list, bdrv_named_nodes_list and qmp_query_block
functions. The changes are split into those patches instead of here to
preserve bisectability.

The fstat call can take a long time to finish when running over
NFS. Add a version of it that runs in the thread pool.
Adapt one of its users, raw_co_get_allocated_file size to use the new
version. That function is called via QMP under the qemu_global_mutex
so it has a large chance of blocking VCPU threads in case it takes too
long to finish.

This is another caller of bdrv_get_allocated_file_size() that needs to
be converted to a coroutine because that function will be made
asynchronous when called (indirectly) from the QMP dispatcher.
This QMP command is a candidate because it calls bdrv_do_query_node_info(),
which in turn calls bdrv_get_allocated_file_size().
We've determined bdrv_do_query_node_info() to be coroutine-safe (see
previous commits), so we can just put this QMP command in a coroutine.
Since qmp_query_block() now expects to run in a coroutine, its callers
need to be converted as well. Convert hmp_info_block(), which calls
only coroutine-safe code, including qmp_query_named_block_nodes()
which has been converted to coroutine in the previous patches.
Now that all callers of bdrv_[co_]block_device_info() are using the
coroutine version, a few things happen:
- we can return to using bdrv_block_device_info() without a wrapper;
- bdrv_get_allocated_file_size() can stop being mixed;
- bdrv_co_get_allocated_file_size() needs to be put under the graph
lock because it is being called wthout the wrapper;
- bdrv_do_query_node_info() doesn't need to acquire the AioContext
because it doesn't call aio_poll anymore;

[relax main loop requirement at qmp_query_block]
Signed-off-by: Fabiano Rosas <farosas@suse.de>
We're currently doing a full query-block just to enumerate the devices
for qmp_nbd_server_add and then discarding the BlockInfoList
afterwards. Alter hmp_nbd_server_start to instead iterate explicitly
over the block_backends list.
This allows the removal of the dependency on qmp_query_block from
hmp_nbd_server_start. This is desirable because we're about to move
qmp_query_block into a coroutine and don't need to change the NBD code
at the same time.

OBS SCM bridge can handle git submodule, while it can't handle (yet?)
meson subprojects. The (ugly, I know!) solution, for now, is to turn
the latter into the former, with commands like the followings:
git submodule add -f https://gitlab.com/qemu-project/berkeley-testfloat-3 subprojects/berkeley-testfloat-3
git -C subprojects/berkeley-testfloat-3 reset --hard 40619cbb3bf32872df8c53cc457039229428a263
(the hash used comes from the subprojects/berkeley-testfloat-3.wrap file)
It's also necessary to manually apply the layering of the packagefiles,
and that is done in the specfile.
Longer term and better solutions could be:
- Make SCM support meson subprojects
- Create standalone packages for the subprojects (and instruct
QEMU to pick stuff from there)

As part of the effort to close the gap with Leap I think we are fine
removing the $pkgversion component to creating a unique CONFIG_STAMP.
This stamp is only used in creating a unique symbol used in ensuring the
dynamically loaded modules correspond correctly to the loading qemu.
The default inputs to producing this unique symbol are somewhat reasonable
as a generic mechanism, but specific packaging and maintenance practices
might require the default to be modified for best use. This is an example
of that.

While using SCSI passthrough, Following scenario makes qemu doesn't
realized the capacity change of remote scsi target:
1. online resize the scsi target.
2. issue 'rescan-scsi-bus.sh -s ...' in host.
3. issue 'rescan-scsi-bus.sh -s ...' in vm.
In above scenario I used to experienced errors while accessing the
additional disk space in vm. I think the reasonable operations should
be:
1. online resize the scsi target.
2. issue 'rescan-scsi-bus.sh -s ...' in host.
3. issue 'block_resize' via qmp to notify qemu.
4. issue 'rescan-scsi-bus.sh -s ...' in vm.
The errors disappear once I notify qemu by block_resize via qmp.
So this patch replaces the number of logical blocks of READ CAPACITY
response from scsi target by qemu's bs->total_sectors. If the user in
vm wants to access the additional disk space, The administrator of
host must notify qemu once resizeing the scsi target.
Bonus is that domblkinfo of libvirt can reflect the consistent capacity
information between host and vm in case of missing block_resize in qemu.
E.g:

The final step of xl migrate|save for an HVM domU is saving the state of
qemu. This also involves releasing all block devices. While releasing
backends ought to be a separate step, such functionality is not
implemented.
Unfortunately, releasing the block devices depends on the optional
'live' option. This breaks offline migration with 'virsh migrate domU
dom0' because the sending side does not release the disks, as a result
the receiving side can not properly claim write access to the disks.
As a minimal fix, remove the dependency on the 'live' option. Upstream
may fix this in a different way, like removing the newly added 'live'
parameter entirely.

Allow for guests with higher amounts of ram. The current thought
is that 2TB specified on qemu commandline would be an appropriate
limit. Note that this requires the next higher bit value since
the highest address is actually more than 2TB due to the pci
memory hole.

[AF: Rebased for v2.7.0-rc2]

Virtio-Console can only process one character at a time. Using it on S390
gave me strange "lags" where I got the character I pressed before when
pressing one. So I typed in "abc" and only received "a", then pressed "d"
but the guest received "b" and so on.
While the stdio driver calls a poll function that just processes on its
queue in case virtio-console can't take multiple characters at once, the
muxer does not have such callbacks, so it can't empty its queue.
To work around that limitation, I introduced a new timer that only gets
active when the guest can not receive any more characters. In that case
it polls again after a while to check if the guest is now receiving input.
This patch fixes input when using -nographic on s390 for me.

When using hugetlbfs (which is required for HV mode KVM on 970), we
check for MMU notifiers that on 970 can not be implemented properly.
So disable the check for mmu notifiers on PowerPC guests, making
KVM guests work there, even if possibly racy in some odd circumstances.

When doing lseek, SEEK_SET indicates that the offset is an unsigned variable.
Other seek types have parameters that can be negative.
When converting from 32bit to 64bit parameters, we need to take this into
account and enable SEEK_END and SEEK_CUR to be negative, while SEEK_SET stays
absolute positioned which we need to maintain as unsigned.

Linux syscalls pass pointers or data length or other information of that sort
to the kernel. This is all stuff you don't want to have sign extended.
Otherwise a host 64bit variable parameter with a size parameter will extend
it to a negative number, breaking lseek for example.
Pass syscall arguments as ulong always.

It's easy enough to handle either per-spec or legacy smbios structures
in the smbios file input without regard to the machine type used, by
simply applying the basic smbios formatting rules. then depending on
what is detected. terminal numm bytes are added or removed for machine
type specific processing.

Certain rom subpackages build from qemu git-submodules call the date
program to include date information in the packaged binaries. This
causes repeated builds of the package to be different, wkere the only
real difference is due to the fact that time build timestamp has
changed. To promote reproducible builds and avoid customers being
prompted to update packages needlessly, we'll use the timestamp of the
VERSION file as the packaging timestamp for all packages that build in a
timestamp for whatever reason.

The sgabios submodule is no longer there, so let's get rid of any
reference to it from our spec files.
Remove no longer supported './configure' options.
We're also not set yet for using the set_version service, so we need to
update the following manually:
- the Version: tags in the spec files
- the rpm/seabios_version and rpm/skiboot_version files (see qemu.spec
for instructions on how to do that)
- the %{sbver} variable in rpm/common.inc
A better solution for handling this aspect is being worked on.
