6086e30026 hw/i2c/smbus_ich9: Fix the confusing contributions-after-2012 statement
The license information in this file is rather confusing. The text
declares LGPL first, but then says that contributions after Jan 2012
are licensed under the GPL instead. How should the average user who
just downloaded the release tarball know which part is now GPL and
which is LGPL? Also, as far as I can see, the file has been added to
QEMU *after* January in 2012, so the whole file should be GPL by
default instead.

Furthermore, looking at the text of the LGPL (see COPYING.LIB in the
top directory), the license clearly states in section "3." that one
should rather replace the license information in such a case instead.
Thus let's clean up the confusing statements and use the proper GPL
text only.

libqos functions should not use functions that require global_qtest to
be set, since such library functions could also be used by tests that
deal with multiple test states. Add a parameter to this function to
explicitly specify the test state.

1e47ac8216 tests/Makefile: Remove unused test-obj-y variable
I recently noticed that test-obj-y contains a file called
tests/check-block-qtest.o which simply does not belong to any .c
file and thus wondered why this is not causing any trouble. It is
only used to add -Itests to the command line (which refers to the
build directory). However, it is not needed because "-iquote $(@D)"
already sets this up in rules.mak. Thus we can simply remove this
variable.

da9cd2d06c tests/qmp-cmd-test: Use qtest_init() instead of qtest_start()
qtest_start() + qtest_end() should be avoided, since they use the
global_qtest variable that we want to get rid of in the long run
(since global_qtest can not be used in tests that have to track
multiple QEMU states, like migration tests). Use qtest_init() and
qtest_quit() instead.

4ac2670bf9 tests: Force Python I/O encoding for check-qapi-schema
test-qapi.py doesn't force a specific encoding for stderr or
stdout, but the reference files used by check-qapi-schema are in
UTF-8.  This breaks check-qapi-schema under certain circumstances
(e.g. if using the C locale and Python < 3.7).

We need to make sure test-qapi.py always generate UTF-8 output
somehow.  On Python 3.7+ we can do it using
`sys.stdout.reconfigure(...)`, but we need a solution that works
with older Python versions.

Instead of trying a hack like reopening sys.stdout and
sys.stderr, we can just tell Python to use UTF-8 for I/O encoding
when running test-qapi.py.  Do it by setting PYTHONIOENCODING.

0b3ca76e52 block: Assert that drv->bdrv_child_perm is set in bdrv_child_perm()
There is no need to check for this because all block drivers that have
children implement bdrv_child_perm and all callers already ensure that
bs->drv is set.

Furthermore, if this check would fail then the callers would end up
with uninitialized values for nperm and nshared.

This patch replaces the check with an assertion.

b8c1f90118 block/ssh: Implement .bdrv_refresh_filename()
This requires some changes to keep iotests 104 and 207 working.

qemu-img info in 104 will now return a filename including the user name
and the port, which need to be filtered by adjusting REMOTE_TEST_DIR in
common.rc.  This additional information has to be marked optional,
however (which is simple as REMOTE_TEST_DIR is a regex), because
otherwise 197 and 215 would fail: They use it (indirectly) to filter
qemu-img create output which contains a backing filename they have
passed to it -- which probably does not contain a user name or port
number.

The problem in 207 is a nice one to have: qemu-img info used to return
json:{} filenames, but with this patch it returns nice plain ones.  We
now need to adjust the filtering to hide the user name (and port number
while we are at it).  The simplest way to do this is to include both in
iotests.remote_filename() so that bdrv_refresh_filename() will not
change it, and then iotests.img_info_log() will filter it correctly
automatically.

qcow2_inc_refcounts_imrt() (through realloc_refcount_array()) can eat

here. So, change the test appropriately.

63159601fb target/arm: Stop using variable length array in dc_zva
Currently the dc_zva helper function uses a variable length
array. In fact we know (as the comment above remarks) that
the length of this array is bounded because the architecture
limits the block size and QEMU limits the target page size.
Use a fixed array size and assert that we don't run off it.

f1e2598c46 target/arm: Implement XPSR GE bits
In the M-profile architecture, if the CPU implements the DSP extension
then the XPSR has GE bits, in the same way as the A-profile CPSR. When
we added DSP extension support we forgot to add support for reading
and writing the GE bits, which are stored in env->GE. We did put in
the code to add XPSR_GE to the mask of bits to update in the v7m_msr
helper, but forgot it in v7m_mrs. We also must not allow the XPSR we
pull off the stack on exception return to set the nonexistent GE bits.
Correct these errors:
 * read and write env->GE in xpsr_read() and xpsr_write()
 * only set GE bits on exception return if DSP present
 * read GE bits for MRS if DSP present

a03ffaefce hw/intc/armv7m_nvic: Don't enable ARMV7M_EXCP_DEBUG from reset
The M-profile architecture specifies that the DebugMonitor exception
should be initially disabled, not enabled. It should be controlled
by the DEMCR register's MON_EN bit, but we don't implement that
register yet (like most of the debug architecture for M-profile).

Note that BKPT instructions will still work, because they
will be escalated to HardFault.

The non-secure versions of the BFAR and BFSR registers are

b01e2f0284 hw/arm/armv7m_nvic: Check subpriority in nvic_recompute_state_secure()
Rule R_CQRV says that if two pending interrupts have the same
group priority then ties are broken by looking at the subpriority.
We had a comment describing this but had forgotten to actually
implement the subpriority comparison. Correct the omission.

(The further tie break rules of "lowest exception number" and
"secure before non-secure" are handled implicitly by the order
in which we iterate through the exceptions in the loops.)

946376c21b osdep: Fix mingw compilation regarding stdio formats
I encountered the following compilation error on mingw:

/mnt/d/qemu/include/qemu/osdep.h:97:9: error: '__USE_MINGW_ANSI_STDIO' macro redefined [-Werror,-Wmacro-redefined]
 #define __USE_MINGW_ANSI_STDIO 1

 #define __USE_MINGW_ANSI_STDIO 0      /* was not defined so it should be 0 */

It turns out that __USE_MINGW_ANSI_STDIO must be set before any
system headers are included, not just before stdio.h.

8ac6557892 qga: Fix mingw compilation warnings on enum conversion
The win2qemu[] is supposed to be the conversion table to convert between
STORAGE_BUS_TYPE in Windows SDK and GuestDiskBusType in qga.

But it was incorrectly written that it forces to set a GuestDiskBusType
value to STORAGE_BUS_TYPE, which generates an enum conversion warning in clang.
