248b920df9 s390x/css: drop data-check in interpretation
The architecture says that channel-data check is indicating that
an uncorrected storage (memory) error has been detected in regard
to the data residing in main storage (memory) that is currently
used for an I/O operation. The described detection is done using
the CBC technology.

The ccw interpretation code is however generating a channel-data check
effectively when the (device specific) ccw_cb returns -EFAULT.  In case
of virtio-ccw devices this happens when mapping memory fails, or when a
NULL pointer is encountered. So this behavior is not architecture
conform.

Furthermore the best fit for these situations (null pointer, mapping a
piece of guest memory fails) from architectural perspective the condition
described as the channel subsystem refers to a location that is not
available, which when encountered shall result in a channel-program
check.

To fix this, all we have to do is to get rid of the switch case matching
-EFAULT: the default is generating a channel-program check.

51af0ec9fa hw/misc/ivshmem: Fix ivshmem_recv_msg() to also work on big endian systems
The "slow" ivshmem-tests currently fail when they are running on a
big endian host:

$ uname -m
ppc64
$ V=1 QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 tests/ivshmem-test -m slow
/x86_64/ivshmem/single: OK
/x86_64/ivshmem/hotplug: OK
/x86_64/ivshmem/memdev: OK
/x86_64/ivshmem/pair: OK
/x86_64/ivshmem/server-msi: qemu-system-x86_64:
 -device ivshmem-doorbell,chardev=chr0,vectors=2: server sent invalid ID message
Broken pipe

The problem is that the server side code in ivshmem_server_send_one_msg()
correctly translates all messages IDs into little endian 64-bit values,
but the client side code in the ivshmem_recv_msg() function does not swap
the byte order back. Fix it by passing the value through le64_to_cpu().

01c36195d6 s390x/pci: fixup ind_offset of msix routing entry
The guest uses the mpcifc instruction to register the aibvo of a zpci
device, which is the starting offset of indicators in the indicator
area and thus remains constant. Each msix vector is an offset from the
aibvo. When we map a msix route to an adapter route, we should not
modify the starting offset, but instead add the vector to the starting
offset to get the absolute offset in the specific route.

2f84a92ec6 tests: Enable the drive_del test also on s390x
We can use the drive_del test on s390x, too, to check that adding and
deleting also works fine with the virtio-ccw bus. But we have to make
sure that we use the devices with the "-ccw" suffix instead of the
"-pci" suffix for the virtio-ccw transport on s390x. Introduce a helper
function called qvirtio_get_dev_type() that returns the correct string
for the current architecture.

Using $(and ...) is dangerous here: It only works as long as the first

first argument is set to 'n' for example. Let's use the "land" make
function instead which has been written explicitely for this purpose.

262a69f428 osdep.h: Prohibit disabling assert() in supported builds
We already have several files that knowingly require assert()
to work, sometimes because refactoring the code for proper
error handling has not been tackled yet; there are probably
other files that have a similar situation but with no comments
documenting the same.  In fact, we have places in migration
that handle untrusted input with assertions, where disabling
the assertions risks a worse security hole than the current
behavior of losing the guest to SIGABRT when migration fails
because of the assertion.  Promote our current per-file
safety-valve to instead be project-wide, and expand it to also
cover glib's g_assert().

Note that we do NOT want to encourage 'assert(side-effects);'
(that is a bad practice that prevents copy-and-paste of code to
other projects that CAN disable assertions; plus it costs
unnecessary reviewer mental cycles to remember whether a project
special-cases the crippling of asserts); and we would LIKE to
fix migration to not rely on asserts (but that takes a big code
audit).  But in the meantime, we DO want to send a message
that anyone that disables assertions has to tweak code in order
to compile, making it obvious that they are taking on additional
risk that we are not going to support.  At the same time, leave
comments mentioning NDEBUG in files that we know still need to
be scrubbed, so there is at least something to grep for.

It would be possible to come up with some other mechanism for
doing runtime checking by default, but which does not abort
the program on failure, while leaving side effects in place
(unlike how crippling assert() avoids even the side effects),
perhaps under the name q_verify(); but it was not deemed worth
the effort (developers should not have to learn a replacement
when the standard C macro works just fine, and it would be a lot
of churn for little gain).  The patch specifically uses #error
rather than #warn so that a user is forced to tweak the header
to acknowledge the issue, even when not using a -Werror
compilation.

825bfa0052 checkpatch: add hwaddr to @typeList
The script doesn't know about all possible types and learn them as
it parses the code. If it reaches a line with a type cast but the
type isn't known yet, it is misinterpreted as an identifier.

For example the following line:

    foo = (hwaddr) -1;

results in the following false-positive to be reported:

ERROR: spaces required around that '-' (ctx:VxV)

Let's add this standard QEMU type to the list of pre-known types.

8e1fe1753a scripts: let checkpatch.pl process an entire GIT branch
Currently before submitting a series, devs should run checkpatch.pl
across each patch to be submitted. This can be automated using a
command such as:

  git rebase -i master -x 'git show | ./scripts/checkpatch.pl -'

This is rather long winded to type, so this patch introduces a way
to tell checkpatch.pl to validate a series of GIT revisions.

There are now three modes it can operate in 1) check a patch 2) check a source
file, or 3) check a git branch.

If no flags are given, the mode is determined by checking the args passed to
the command. If the args contain a literal ".." it is treated as a GIT revision
list. If the args end in ".patch" or equal "-" it is treated as a patch file.
Otherwise it is treated as a source file.

This automatic guessing can be overridden using --[no-]patch --[no-]file or
--[no-]branch

For example to check a GIT revision list:

    $ ./scripts/checkpatch.pl master..
    total: 0 errors, 0 warnings, 297 lines checked

    b886d352a2bf58f0996471fb3991a138373a2957 has no obvious style problems and is ready for submission.
    total: 0 errors, 0 warnings, 182 lines checked

    2a731f9a9ce145e0e0df6d42dd2a3ce4dfc543fa has no obvious style problems and is ready for submission.
    total: 0 errors, 0 warnings, 102 lines checked

    11844169bcc0c8ed4449eb3744a69877ed329dd7 has no obvious style problems and is ready for submission.

If a genuine patch filename contains the characters '..' it is
possible to force interpretation of the arg as a patch

  $ ./scripts/checkpatch.pl --patch master..

will force it to load a patch file called "master..", or equivalently

  $ ./scripts/checkpatch.pl --no-branch master..

will simply turn off guessing of GIT revision lists.

5e95381260 hyperv: add header with protocol definitions
The definitions for Hyper-V emulation are currently taken from a header
imported from the Linux kernel.

However, as these describe a third-party protocol rather than a kernel
API, it probably wasn't a good idea to publish it in the kernel uapi.

This patch introduces a header that provides all the necessary
definitions, superseding the one coming from the kernel.

The new header supports (temporary) coexistence with the kernel one.
The constants explicitly named in the Hyper-V specification (e.g. msr
numbers) are defined in a non-conflicting way.  Other constants and
types have got new names.

While at this, the protocol data structures are defined in a more
conventional way, without bitfields, enums, and excessive unions.

The code using this stuff is adjusted, too; it can now be built both
with and without the kernel header in the tree.

Starting with Windows Server 2012 and Windows 8, if
CPUID.40000005.EAX contains a value of -1, Windows assumes specific
limit to the number of VPs. In this case, Windows Server 2012
guest VMs may use more than 64 VPs, up to the maximum supported
number of processors applicable to the specific Windows
version being used.

https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/tlfs

For compatibility, Let's introduce a new property for X86CPU,
named "x-hv-max-vps" as Eduardo's suggestion, and set it
to 0x40 before machine 2.10.

(The "x-" prefix indicates that the property is not supposed to
be a stable user interface.)

    'N;N;N;N;N;N;N; {s|fprintf(.*".*warning[,:] \(.*\)\\n"\(.*\));|warn_report("\1"\2);|Ig}' \
    {} +

Indentation fixed up manually afterwards.

Some of the lines were manually edited to reduce the line length to below
80 charecters. Some of the lines with newlines in the middle of the
string were also manually edit to avoid checkpatch errrors.

The #include lines were manually updated to allow the code to compile.

Several of the warning messages can be improved after this patch, to
keep this patch mechanical this has been moved into a later patch.

converted uses of error_report("warning:"... to use warn_report()

67548f0965 kvm: kvm_log_sync() is only called with known memory sections
Flatview will make sure that we can only end up in this function with
memory sections that correspond to exactly one slot. So we don't
have to iterate multiple times. There won't be overlapping slots but
only matching slots.

Properly align the section and look up the corresponding slot. This
heavily simplifies this function.

We can now get rid of kvm_lookup_overlapping_slot().

f357f564be kvm: we never have overlapping slots in kvm_set_phys_mem()
The way flatview handles memory sections, we will never have overlapping
memory sections in kvm.

address_space_update_topology_pass() will make sure that we will only
get called for

a) an existing memory section for which we only update parameters
(log_start, log_stop).
b) an existing memory section we want to delete (region_del)
c) a brand new memory section we want to add (region_add)

We cannot have overlapping memory sections in kvm as we will first remove
the overlapping sections and then add the ones without conflicts.

Therefore we can remove the complexity for handling prefix and suffix
slots.

d72bc7f6f8 i386/kvm: advertise Hyper-V frequency MSRs
As of kernel commit eb82feea59d6 ("KVM: hyperv: support HV_X64_MSR_TSC_FREQUENCY
and HV_X64_MSR_APIC_FREQUENCY"), KVM supports two new MSRs which are required
for nested Hyper-V to read timestamps with RDTSC + TSC page.

This commit makes QEMU advertise the MSRs with CPUID.40000003H:EAX[11] and
CPUID.40000003H:EDX[8] as specified in the Hyper-V TLFS and experimentally
verified on a Hyper-V host. The feature is enabled with the existing hv-time CPU
flag, and only if the TSC frequency is stable across migrations and known.
