    QEMU_IFLA_BRPORT_BACKUP_PORT (from linux v4.19).

These new types fix this error flow with sudo:

Unknown host QEMU_IFLA type: 50
Unknown host QEMU_IFLA type: 51
Unknown QEMU_IFLA_BRPORT type 33

9d0bd0cdd0 linux-user: Check sscanf return value in open_net_route()
Coverity warns (CID 1390634) that open_net_route() is not
checking the return value from sscanf(), which means that
it might then use values that aren't initialized.

Errors here should in general not happen since we're passing
an assumed-good /proc/net/route from the host kernel, but
if we do fail to parse a line then just skip it in the output
we pass to the guest.

e633a5c661 configure: Avoid non-portable 'test -o/-a'
POSIX says that it is better to use &&/|| and two separate test
invocations than it is to try and use -a and -o (in fact, there
are some tests that are inherently ambiguous to parse if the
user passes in corner-case input like "(").

Since we cannot guarantee which shell runs configure, we cannot
rely on -o/-a always following bash's parser rules.

70c9483a30 target/moxie: Fix LGPL information in the file headers
It's either "GNU *Library* General Public License version 2" or "GNU
Lesser General Public License version *2.1*", but there was no "version
2.0" of the "Lesser" license. So assume that version 2.1 is meant here.
Also the files mentioned the GPL instead of the LGPL after declaring
that the files are licensed under the LGPL, so change these spots to
use LGPL, too.

68aa851aa2 target/hppa: fix PSW Q bit behaviour to match hardware
PA-RISC specification says: "Setting the PSW Q-bit, PSW{28}, to 1
with this instruction, if it was not already 1, is an undefined
operation." However, at least HP-UX 10.20 sets the Q bit from 0 to 1
with the SSM instruction. Tested this both on HP9000/712 and
HP9000/785/C3750, both machines set the Q bit from 0 to 1 without
exception. This makes HP-UX 10.20 progress a little bit further.

9fd9b7de61 accel/tcg: Consider cluster index in tb_lookup__cpu_state()
In commit f7b78602fd we added the CPU cluster number to the
cflags field of the TB hash; this included adding it to the value
kept in tb->cflags, since we pass that field directly into the hash
calculation in some places. Unfortunately we forgot to check whether
other parts of the code were doing comparisons against tb->cflags
that would need to be updated.

It turns out that there is exactly one such place: the
tb_lookup__cpu_state() function checks whether the TB it has
found in the tb_jmp_cache has a tb->cflags matching the cf_mask
that is passed in. The tb->cflags has the cluster_index in it
but the cf_mask does not.

Hoist the "add cluster index to the cf_mask" code up from
tb_htable_lookup() to tb_lookup__cpu_state() so it can be considered
in the "did this TB match in the jmp cache" condition, as well as
when we do the full hash lookup by physical PC, flags, etc.
(tb_htable_lookup() is only called from tb_lookup__cpu_state(),
so this change doesn't require any further knock-on changes.)

a15945d98d target/arm: Make FPSCR/FPCR trapped-exception bits RAZ/WI
The {IOE, DZE, OFE, UFE, IXE, IDE} bits in the FPSCR/FPCR are for
enabling trapped IEEE floating point exceptions (where IEEE exception
conditions cause a CPU exception rather than updating the FPSR status
bits). QEMU doesn't implement this (and nor does the hardware we're
modelling), but for implementations which don't implement trapped
exception handling these control bits are supposed to be RAZ/WI.
This allows guest code to test for whether the feature is present
by trying to write to the bit and checking whether it sticks.

QEMU is incorrectly making these bits read as written. Make them
RAZ/WI as the architecture requires.

In particular this was causing problems for the NetBSD automatic
test suite.

5614ca800e hw/arm/boot: Support DTB autoload for firmware-only boots
The arm_boot_info struct has a skip_dtb_autoload flag: if this is
set to true by the board code then arm_load_kernel() will not
load the DTB itself, but will leave this for the board code to
do itself later. However, the check for this is done in a
code path which is only executed for the case where we load
a kernel image file. If we're taking the "boot via firmware"
code path then the flag isn't honoured and the DTB is never
loaded.

We didn't notice this because the only real user of "boot
via firmware" that cares about the DTB is the virt board
(for UEFI boot), and that always wants skip_dtb_autoload
anyway. But the SBSA reference board model we're planning to
add will want the flag to behave correctly.

Now we've refactored the arm_load_kernel() function, the
fix is simple: drop the early 'return' so we fall into
the same "load the DTB" code the boot-direct-kernel path uses.

3a471103ac target/arm: Clean TBI for data operations in the translator
This will allow TBI to be used in user-only mode, as well as
avoid ping-ponging the softmmu TLB when TBI is in use.  It
will also enable other armv8 extensions.

51bf0d7aa9 target/arm: Default handling of BTYPE during translation
The branch target exception for guarded pages has high priority,
and only 8 instructions are valid for that case.  Perform this
check before doing any other decode.

Clear BTYPE after all insns that neither set BTYPE nor exit via
exception (DISAS_NORETURN).

Not yet handled are insns that exit via DISAS_NORETURN for some
other reason, like direct branches.
