when host mmu got updated, it should invalidate TLB & page-struct cache.
currently, there is no mmu update will be done after any AP start, so the

Per SDM Vol. 2:
If CPUID.80000008H:EAX[7:0] is supported, the maximum physical address
number supported should come from this field.
This patch gets the maximum physical address number from CPUID leaf
0x80000008 and calculates the physical address mask when the leaf is
available.
Currently ACRN does not support platforms w/o this leaf and will panic
on such platforms.
Also call get_cpu_capabilities() earlier since the physical address mask
is required for initializing paging.

Per SDM:
When CPUID executes with EAX set to 80000000H, the processor returns
the highest value the processor recognizes for returning extended
processor information. The value is returned in the EAX register and is
processor specific.
This patch caches this value in the global cpuinfo_x86.cpuid_leaves. This
value will be used to check the availability of any CPUID extended
function.

According to C99:
The empty list in a function declarator that is not part of a definition of
that function specifies that no information about the number or types of the
parameters is supplied.
This means gcc is happy with the following code, which is undesirable.
void foo(); /* declaration with an empty parameter list */
void bar() {
foo(); /* OK */
foo(1); /* OK */
foo(1, 2); /* OK */
}
This patch fixes declarations of functions with empty parameter lists by adding
an unnamed parameter of type void, which is the standard way to specify that a
function has no parameters. The following coccinelle script is used.
@@
type T;
identifier f;
@@
-T f();
+T f(void);
New compilation errors are fixed accordingly.
