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.

The entry offset when taking an exception to AArch64 from a lower
exception level may be 0x400 or 0x600. 0x400 is used if the
implemented exception level immediately lower than the target level
is using AArch64, and 0x600 if it is using AArch32. We were
incorrectly implementing this as checking the exception level
that the exception was taken from. (The two can be different if
for example we take an exception from EL0 to AArch64 EL3; we should
in this case be checking EL2 if EL2 is implemented, and EL1 if
EL2 is not implemented.)

Handling of semihosting calls should depend on the register width
of the calling code, not on that of any higher exception level,
so we need to identify and handle semihosting calls before we
decide whether to deliver the exception as an entry to AArch32
or AArch64. (EXCP_SEMIHOST is also an "internal exception" so
it has no target exception level in the first place.)
This will allow AArch32 EL1 code to use semihosting calls when
running under an AArch64 EL3.
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
If EL2 or EL3 is present on an AArch64 CPU, then exceptions can be
taken to an exception level which is running AArch32 (if only EL0
and EL1 are present then EL1 must be AArch64 and all exceptions are
taken to AArch64). To support this we need to have a single
implementation of the CPU do_interrupt() method which can handle both
32 and 64 bit exception entry.
Pull the common parts of aarch64_cpu_do_interrupt() and
arm_cpu_do_interrupt() out into a new function which calls
either the AArch32 or AArch64 specific entry code once it has
worked out which one is needed.
We temporarily special-case the handling of EXCP_SEMIHOST to
avoid an assertion in arm_el_is_aa64(); the next patch will
pull all the semihosting handling out to the arm_cpu_do_interrupt()
level (since semihosting semantics depend on the register width
of the calling code, not on that of any higher EL).

It's going to be quite common that bus masters out in device land
have pointers to the same memory region for their mastering yet
each will need to create its own address space. Let the memory
API implement sharing for them.
Aside from the perf optimisations, this should reduce the amount
of redundant output on info mtree as well.
Thee returned value will be malloced, but the malloc will be
automatically freed when the AS runs out of refs.

[PMM: dropped check for NULL root as unused; added doc-comment;
squashed Peter C's reference-counting patch into this one;
don't compare name string when deciding if we can share ASes;
read as->malloced before the unref of as->root to avoid possible
read-after-free if as->root was the owner of as]
