we find that some apps will read cpuinfo when start up,
they need the string as follows:
"Processor : AArch64 Processor rev 0 (aarch64)"
Then thay could load the corresponding libs. But now
arm64 platform's cpuinfo don't has this now, so
we need add this.

When DEFERRED_STRUCT_PAGE_INIT is enabled, just a subset of memmap at boot
are initialized, then the rest are initialized in parallel by starting one-off
"pgdatinitX" kernel thread for each node X.
If page_ext_init is called before it, some pages will not have valid extension,
so move page_ext_init() after it.
