When LAPIC timer is working in oneshot or periodic mode, OS uses
initial counter register/current counter register to program
a timer. Both initial counter and current counter depend on the
LAPIC frequency. ACRN emulated vLAPIC timer based on the TSC.
vLAPIC freq is the same as TSC freq.

For platform that supports RRSBA (Restricted Return Stack Buffer
Alternate), using retpoline may not be sufficient to guard against branch
history injection or intra-mode branch target injection. RRSBA must
be disabled to prevent CPUs from using alternate predictors for RETs.
Quoting Intel CVE-2022-0001/CVE-2022-0002:
Where software is using retpoline as a mitigation for BHI or intra-mode BTI,
and the processor both enumerates RRSBA and enumerates RRSBA_DIS controls,
it should disable this behavior.
...
Software using retpoline as a mitigation for BHI or intra-mode BTI should use
these new indirect predictor controls to disable alternate predictors for RETs.

Commit d575edf79a changes the internal
implementation of wait_event and signal_event to use a counter instead
of a boolean value.
The background was:
ACRN utilizes vcpu_make_request and signal_event pair to shoot down
other vcpus and let them wait for signals. vcpu_make_request eventually
leads to target vcpu calling wait_event.
However vcpu_make_request/signal_event pair was not thread-safe,
and concurrent calls of this pair of API could lead to problems.
One such example is the concurrent wbinvd emulation, where vcpus may
concurrently issue vcpu_make_request/signal_event to synchronize wbinvd
emulation.
d575edf commit uses a counter in internal implementation of
wait_event/signal_event to avoid data races.
However by using a counter, the wait/signal pair now carries semantics of
semaphores instead of events. Semaphores require caller to carefully
plan their calls instead of multiply signaling any number of times to the same
event, which deviates from the original "event" semantics.
This patch changes the API implementation back to boolean-based, and
re-resolve the issue of concurrent wbinvd in next patch.
This also partially reverts commit 10963b04d1,
which was introduced because of the d575edf.

- add a new acrn-dm parameter "--iasl <iasl_compiler_path>"

acrn-dm uses <iasl_compiler_path> as the path to the "iasl" compiler;
otherwise, "which iasl" is used to detect the "iasl" compiler.
If "iasl" is not found at run time, refuse to launch the post-launched VM
and exit directly.
