- remove .data and .text directives. We want to place all the boot data and
text in the .entry section since the boot code is different from others
in terms of relocation fixup. With this change, the page tables are in
entry section now and it's aligned at 4KB.
- regardless CONFIG_MULTIBOOT2 is set or not, the 64-bit entry offset is
fixed at 0x1200:
0x00 -- 0x10: Multiboot1 header
0x10 -- 0x88: Multiboot2 header if CONFIG_MULTIBOOT2 is set
0x1000: start of entry section: cpu_primary_start_32
0x1200: cpu_primary_start_64 (thanks to the '.org 0x200' directive)
GDT tables
initial page tables
etc.
