The macro DO_UPCAST() is incorrectly named: it converts from a
parent class to a derived class (which is a downcast). Better,
and more consistent with some of the other qapi visitors, is
to use the container_of() macro through a to_FOO() helper. Names
like 'to_ov()' may be a bit short, but for a static helper it
doesn't hurt too much, and matches existing practice in files
like qmp-input-visitor.c.
Our current definition of container_of() is weaker than
DO_UPCAST(), in that it does not require the derived class to
have Visitor as its first member, but this does not hurt our
usage patterns in qapi visitors.

We already modify the processor feature bits to not report EL3
support to the guest if EL3 isn't enabled for the CPU we're emulating.
Add similar support for not reporting EL2 unless it is enabled.
This is necessary because real world guest code running at EL3
(trusted firmware or bootloaders) will query the ID registers to
determine whether it should start a guest Linux kernel in EL2 or EL3.

SPSR_ABT, SPSR_UND and SPSR_FIQ are visible and fully functional from
EL3 even if the CPU has no EL2 (unlike some others which are RES0
from EL3 in that configuration). Move them from el2_cp_reginfo[] to
v8_cp_reginfo[] so they are always present.

If executing ALIGN with shift count bp=0 within mips64 emulation,
the result of the operation should be sign extended.
Taken from the official documentation (pseudo code) :
ALIGN:
tmp_rt_hi = unsigned_word(GPR[rt]) << (8*bp)
tmp_rs_lo = unsigned_word(GPR[rs]) >> (8*(4-bp))
tmp = tmp_rt_hi || tmp_rt_lo
GPR[rd] = sign_extend.32(tmp)

Replace the uint8 softfloat-specific typedef with uint8_t.

find include hw fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\buint8\b/uint8_t/g'
together with manual removal of the typedef definition and
manual fixing of more erroneous uses found via test compilation.
It turns out that the only code using this type is an accidental
use where uint8_t was intended anyway...

Backports commit f42c222482b651400f0fa417eb174da1c9502c1c from qemu
This patch enables migrating vcpu's TSC rate. If KVM on the
destination machine supports TSC scaling, guest programs will
observe a consistent TSC rate across the migration.
If TSC scaling is not supported on the destination machine, the
migration will not be aborted and QEMU on the destination will
not set vcpu's TSC rate to the migrated value.
If vcpu's TSC rate specified by CPU option 'tsc-freq' on the
destination machine is inconsistent with the migrated TSC rate,
the migration will be aborted.
For backwards compatibility, the migration of vcpu's TSC rate is
disabled on pc-*-2.5 and older machine types.
