To ARM64, we should use '(VMAP_VIRT_START + GB(1))' as VMAP_VIRT_END,
but not '(VMAP_VIRT_START + GB(1) - 1)'.
Seeing 'vm_end[type] = PFN_DOWN(end - start);' in vm_init_type,
if not correct VMAP_VIRT_END, one page is wasted.

To ARM64, setup_xenheap_mappings may call alloc_boot_pages to allocate
first level page table, if there is a big chunk memory (ie, >512GB).
So, need to make sure boot pages are ready before setup xenheap mappings.

To ARM64, "frametable_size >> SECOND_SHIFT" means the number
of second level entries, not the number of second level pages.
"DIV_ROUND_UP(frametable_size >> SECOND_SHIFT, LPAE_ENTRIES)"
is the correct way to calculate the second level pages needed
for frametable m
In setup_pagetables, need to map BOOT_RELOC_VIRT_START
in xen_second and boot_second, so we can merge the two
pieces code into one code block.
Also no need to use write_pte when map BOOT_RELOC_VIRT_START
in xen_second, because CPU0 is using boot page tables now.

There is no function change in this patch, I just think
there is no need to use flush_xen_data_tlb_range_va_local and write_pte
at that point. And I tested this patch on AArch64.

Yeah. T
The 'Base address for 4K mapping' is '(x19 >> THIRD_SHIFT) << THIRD_SHIFT'.
Also we are building 4K page mapping, not section mapping.
