442ef32ee5 pc-bios/s390-ccw/Makefile: Use -z noexecstack to silence linker warning
Recent versions of ld complain when linking the s390-ccw bios:

 /usr/bin/ld: warning: start.o: missing .note.GNU-stack section implies
              executable stack
 /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in
              a future version of the linker

We can silence the warning by telling the linker to mark the stack
as not executable.

0c2a6e1242 pc-bios/s390-ccw: Get rid of the the __u* types
The types starting with double underscores have likely been
introduced into the s390-ccw bios to be able to re-use structs
from the Linux kernel in the past, but the corresponding structs
in cio.h have been changed there a long time ago already to not
use the variants with the double underscores anymore:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/diff/drivers/s390/cio/cio.h?id=cd6b4f27b9bb2a

So it would be good to replace these in the s390-ccw bios now, too.

f7f2f96f33 s390-ccw: Getting rid of ulong
Any good reason why this still exist?
I can understand u* and __u* to be linux kernel like, but ulong?

40a205da41 target/i386: emulate 64-bit ring 0 for linux-user if LM feature is set
32-bit binaries can run on a long mode processor even if the kernel
is 64-bit, of course, and this can have slightly different behavior;
for example, SYSCALL is allowed on Intel processors.

Allow reporting LM to programs running under user mode emulation,
so that "-cpu" can be used with named CPU models even for qemu-i386
and even without disabling LM by hand.

Fortunately, most of the runtime code in QEMU has to depend on HF_LMA_MASK
or on HF_CS64_MASK (which is anyway false for qemu-i386's 32-bit code
segment) rather than TARGET_X86_64, therefore all that is needed is an
update of linux-user's ring 0 setup.

d903259dd2 target/i386: ignore CPL0-specific features in user mode emulation
Features such as PCID are only accessible through privileged operations,
and therefore have no impact on any user-mode operation.  Allow reporting
them to programs running under user mode emulation, so that "-cpu" can be
used with more named CPU models.

XSAVES would be similar, but it doesn't make sense to provide it until
XSAVEC is implemented.

With this change, all CPUs up to Broadwell-v4 can be emulate.  Skylake-Client
requires XSAVEC, while EPYC also requires SHA-NI, MISALIGNSSE and TOPOEXT.
MISALIGNSSE is not hard to implement, but I am not sure it is worth using
a precious hflags bit for it.

9fb4f5f5a1 target/i386: ignore ARCH_CAPABILITIES features in user mode emulation
ARCH_CAPABILITIES is only accessible through a read-only MSR, so it has
no impact on any user-mode operation (user-mode cannot read the MSR).
So do not bother printing warnings about it in user mode emulation.

5bef742cc4 target/i386: Export MSR_ARCH_CAPABILITIES bits to guests
On Intel CPUs there are certain bits in MSR_ARCH_CAPABILITIES that
indicates if the CPU is not affected by a vulnerability. Without these
bits guests may try to deploy the mitigation even if the CPU is not
affected.

Export the bits to guests that indicate immunity to hardware
vulnerabilities.

db5a06b3a2 target/i386/WHPX: Fix error message when fail to set ProcessorCount
003f230e37 ("machine: Tweak the order of topology members in struct
CpuTopology") changes the meaning of MachineState.smp.cores from "the
number of cores in one package" to "the number of cores in one die"
and doesn't fix other uses of MachineState.smp.cores. And because of
the introduction of cluster, now smp.cores just means "the number of
cores in one cluster". This clearly does not fit the semantics here.

And before this error message, WHvSetPartitionProperty() is called to
set prop.ProcessorCount.

So the error message should show the prop.ProcessorCount other than
"cores per cluster" or "cores per package".

641b841722 accel: Re-enable WHPX cross-build on case sensitive filesystems
Since MinGW commit 395dcfdea ("rename hyper-v headers and def
files to lower case") [*], WinHvPlatform.h and WinHvEmulation.h
got respectively renamed as winhvplatform.h / winhvemulation.h.

The mingw64-headers package included in the Fedora version we
use for CI does include this commit; and meson fails to detect
these present-but-renamed headers while cross-building (on
case-sensitive filesystems).

Use the renamed header in order to detect and successfully
cross-build with the WHPX accelerator.

Note, on Windows hosts, the libraries are still named as
WinHvPlatform.dll and WinHvEmulation.dll, so we don't bother
renaming the definitions used by load_whp_dispatch_fns() in
target/i386/whpx/whpx-all.c.

ca3fcdeeee net/vhost-net: do not assert on null pointer return from tap_get_vhost_net()
When 'vhost=off' or no vhost specific options at all are passed for the tap
net-device backend, tap_get_vhost_net() can return NULL. The function
net_init_tap_one() does not call vhost_net_init() on such cases and therefore
vhost_net pointer within the tap device state structure remains NULL. Hence,
assertion here on a NULL pointer return from tap_get_vhost_net() would not be
correct. Remove it and fix the crash generated by qemu upon initialization in
the following call chain :

qdev_realize() -> pci_qdev_realize() -> virtio_device_realize() ->
virtio_bus_device_plugged() -> virtio_net_get_features() -> get_vhost_net()

6b90a4cdc0 escc: emulate dip switch language layout settings on SUN keyboard
SUN Type 4, 5 and 5c keyboards have dip switches to choose the language layout
of the keyboard. Solaris makes an ioctl to query the value of the dipswitches
and uses that value to select keyboard layout.  Also the SUN bios like the one
in the file ss5.bin uses this value to support at least some keyboard layouts.
However, the OpenBIOS provided with qemu is hardcoded to always use an US
keyboard layout.

Before this patch, qemu allways gave dip switch value 0x21 (US keyboard),
this patch uses a command line switch like
"-global escc.chnA-sunkbd-layout=de" to select dip switch value. A table is
used to lookup values from arguments like:

-global escc.chnA-sunkbd-layout=fr
-global escc.chnA-sunkbd-layout=es

But the patch also accepts numeric dip switch values directly:

-global escc.chnA-sunkbd-layout=0x2b
-global escc.chnA-sunkbd-layout=43

Both values above are the same and select swedish keyboard as explained in
table 3-15 at
https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html

Unless you want to do a full Solaris installation but happen to have
access to a Sun bios file, the easiest way to test that the patch works
is to:

qemu-system-sparc -global escc.chnA-sunkbd-layout=sv -bios /path/to/ss5.bin

If you already happen to have a Solaris installation in a qemu disk image
file you can easily try different keyboard layouts after this patch is
applied.

44a7c2ecd4 target/sparc: Use tcg_gen_lookup_and_goto_ptr for v9 WRASI
We incorporate %asi into tb->flags so that we may generate
inline code for the many ASIs for which it is easy to do so.
Setting %asi is common for e.g. memcpy and memset performing
block copy and clear, so it is worth noticing this case.

We must end the TB but do not need to return to the main loop.
