This patch introduces static memory initialization, during system RAM boot

The word "RAM" looks spurious.
Thx. I check the "spurious" in dictionary, it means fake? So I will leave "during
system boot up"
here.
Yes, this reads better.
2. scrub the page in need synchronously.
Can you explain why this is necessary?
Since I'm borrowing the logic in free_heap_pages, I'm also trying to cover all
the scenarios here like it does.
So I assume that free_staticmem_page will not only be used on initialization,
but also when destroying/rebooting the domain.
On these cases, it is necessary to scrub the page, ig.
I wasn't asking about scrubbing specifically but instead why it is
synchronous. Sorry for the confusion.
