a5754847e0 tests/avocado: Disable the test_sbsaref_edk2_firmware by default
The test fails occasionally, see e.g.:

 https://gitlab.com/thuth/qemu/-/jobs/4196177756#L489
 https://gitlab.com/thuth/qemu/-/jobs/4623296271#L290

It also fails on my laptop in ca. 50% of all runs. Thus disable it by
default by using the QEMU_TEST_FLAKY_TESTS environment variable to fence
it (which we also already use in flaky qtests). While we're at it, also
document this variable in docs/devel/testing.rst.

7f114a5807 linux-user/elfload: Fix /proc/cpuinfo features: on s390x
elf_hwcap_str() takes a bit number, but compares it for equality with
the HWCAP_S390_* masks. This causes /proc/cpuinfo to display incorrect
hwcaps.

Fix by introducing the HWCAP_S390_NR_* constants and using them in
elf_hwcap_str() instead of the HWCAP_S390_*. While at it, add the
missing nnpa, pcimio and sie hwcaps from the latest kernel.

Output before:

	features	: esan3 zarch stfle msa

Output after:

	features	: esan3 zarch stfle msa ldisp eimm etf3eh highgprs vx vxe

d9458f990a s390x: Fix QEMU abort by selecting S390_FLIC_KVM
If QEMU is built with --without-default-devices, the s390-flic-kvm
device is missing and QEMU aborts when started with the KVM accelerator.
Make sure it's available by selecting S390_FLIC_KVM in Kconfig.

Consequently, this also fixes an abort in tests/qtest/migration-test.

66547f416a block/nvme: invoke blk_io_plug_call() outside q->lock
blk_io_plug_call() is invoked outside a blk_io_plug()/blk_io_unplug()
section while opening the NVMe drive from:

  nvme_file_open() ->
  nvme_init() ->
  nvme_identify() ->
  nvme_admin_cmd_sync() ->
  nvme_submit_command() ->
  blk_io_plug_call()

blk_io_plug_call() immediately invokes the given callback when the
current thread is not plugged, as is the case during nvme_file_open().

Unfortunately, nvme_submit_command() calls blk_io_plug_call() with
q->lock still held:

    ...
    q->sq.tail = (q->sq.tail + 1) % NVME_QUEUE_SIZE;
    q->need_kick++;
    blk_io_plug_call(nvme_unplug_fn, q);
    qemu_mutex_unlock(&q->lock);
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^

nvme_unplug_fn() deadlocks trying to acquire q->lock because the lock is
already acquired by the same thread. The symptom is that QEMU hangs
during startup while opening the NVMe drive.

Fix this by moving the blk_io_plug_call() outside q->lock. This is safe
because no other thread runs code related to this queue and
blk_io_plug_call()'s internal state is immune to thread safety issues
since it is thread-local.

0d0be87659 virtio-gpu: replace the surface with null surface when resetting
The primary guest scanout shows the booting screen right after reboot
but additional guest displays (i.e. max_ouptuts > 1) will keep displaying
the old frames until the guest virtio gpu driver gets initialized, which
could cause some confusion. A better way is to to replace the surface with
a place holder that tells the display is not active during the reset of
virtio-gpu device.

And to immediately update the surface with the place holder image after
the switch, displaychangelistener_gfx_switch needs to be called with
'update == TRUE' in dpy_gfx_replace_surface when the new surface is NULL.

e60a7d0d4d accel/tcg: Zero-pad PC in TCG CPU exec trace lines
In commit f0a08b0913 we changed the type of the PC from
target_ulong to vaddr.  In doing so we inadvertently dropped the
zero-padding on the PC in trace lines (the second item inside the []
in these lines).  They used to look like this on AArch64, for
instance:

Trace 0: 0x7f2260000100 [00000000/0000000040000000/00000061/ff200000]

and now they look like this:
Trace 0: 0x7f4f50000100 [00000000/40000000/00000061/ff200000]

and if the PC happens to be somewhere low like 0x5000
then the field is shown as /5000/.

This is because TARGET_FMT_lx is a "%08x" or "%016x" specifier,
depending on TARGET_LONG_SIZE, whereas VADDR_PRIx is just PRIx64
with no width specifier.

Restore the zero-padding by adding an 016 width specifier to
this tracing and a couple of others that were similarly recently
changed to use VADDR_PRIx without a width specifier.

We can't unfortunately restore the "32-bit guests are padded to
8 hex digits and 64-bit guests to 16 hex digits" behaviour so
easily.

eeb9578c36 target/arm/ptw.c: Account for FEAT_RME when applying {N}SW, SA bits
In get_phys_addr_twostage() the code that applies the effects of
VSTCR.{SA,SW} and VTCR.{NSA,NSW} only updates result->f.attrs.secure.
Now we also have f.attrs.space for FEAT_RME, we need to keep the two
in sync.

These bits only have an effect for Secure space translations, not
for Root, so use the input in_space field to determine whether to
apply them rather than the input is_secure. This doesn't actually
make a difference because Root translations are never two-stage,
but it's a little clearer.

3f74da440d target/arm: Fix S1_ptw_translate() debug path
In commit fe4a5472cc we rearranged the logic in S1_ptw_translate()
so that the debug-access "call get_phys_addr_*" codepath is used both
when S1 is doing ptw reads from stage 2 and when it is doing ptw
reads from physical memory.  However, we didn't update the
calculation of s2ptw->in_space and s2ptw->in_secure to account for
the "ptw reads from physical memory" case.  This meant that debug
accesses when in Secure state broke.

Create a new function S2_security_space() which returns the
correct security space to use for the ptw load, and use it to
determine the correct .in_secure and .in_space fields for the
stage 2 lookup for the ptw load.

aab746106c linux-user: Remove pointless NULL check in clock_adjtime handling
In the code for TARGET_NR_clock_adjtime, we set the pointer phtx to
the address of the local variable htx.  This means it can never be
NULL, but later in the code we check it for NULL anyway.  Coverity
complains about this (CID 1507683) because the NULL check comes after
a call to clock_adjtime() that assumes it is non-NULL.

Since phtx is always &htx, and is used only in three places, it's not
really necessary.  Remove it, bringing the code structure in to line
with that for TARGET_NR_clock_adjtime64, which already uses a simple
'&htx' when it wants a pointer to 'htx'.

76f9d6ad19 tcg: Use HAVE_CMPXCHG128 instead of CONFIG_CMPXCHG128
We adjust CONFIG_ATOMIC128 and CONFIG_CMPXCHG128 with
CONFIG_ATOMIC128_OPT in atomic128.h.  It is difficult
to tell when those changes have been applied with the
ifdef we must use with CONFIG_CMPXCHG128.  So instead
use HAVE_CMPXCHG128, which triggers -Werror-undef when
the proper header has not been included.

Improves tcg_gen_atomic_cmpxchg_i128 for s390x host, which
requires CONFIG_ATOMIC128_OPT.  Without this we fall back
to EXCP_ATOMIC to single-step 128-bit atomics, which is
slow enough to cause some tests to time out.

deba78709a accel/tcg: Always lock pages before translation
We had done this for user-mode by invoking page_protect
within the translator loop.  Extend this to handle system
mode as well.  Move page locking out of tb_link_page.

d713cf4d6c linux-user/arm: Do not allocate a commpage at all for M-profile CPUs
Since commit fbd3c4cff6 ("linux-user/arm: Mark the commpage
executable") executing bare-metal (linked with rdimon.specs)
cortex-M code fails as:

  $ qemu-arm -cpu cortex-m3 ~/hello.exe.m3
  qemu-arm: ../../accel/tcg/user-exec.c:492: page_set_flags: Assertion `last <= GUEST_ADDR_MAX' failed.
  Aborted (core dumped)

Commit 4f5c67f8df ("linux-user/arm: Take more care allocating
commpage") already took care of not allocating a commpage for
M-profile CPUs, however it had to be reverted as commit 6cda41daa2.

Re-introduce the M-profile fix from commit 4f5c67f8df.

Fixes: fbd3c4cff6 ("linux-user/arm: Mark the commpage executable")
