Eventually went with not using in-place linked list for PMM (Don't really want to mix up PMM and VMM).
...
So yeah, now keep trace of those physical pages on kernel heap, Windows does that, linux does that, I have to do that since there are more attributes(paged/non-paged) that the kernel requires.
Hmm finished PMM alpha and redefined all those PMM/VMM interfaces.
The code is still broken right now.

not quite working stuff. Rethinking memory allocator. Maybe not buddy allocator. Basically use salloc for heap for now and talloc with O(log n) for system page allocation. A linear external allocator is not necessarily needed. Todo: finish talloc and add lock/alignment to salloc

Interrupt working (Except that I need to remap PIC).
...
1. Fix a stupid mistake in idt dispatch table (IDT_ENTRY_NUM instead of IDT_ENTRY_SIZE)!
2. Figured out that before enabling APIC, the PIC is not completely disabled/remapped. Took hours to debug why immediately after enabling interrupt, a double fault happens when executing "mov eax, 0". Turned out that PIC maps timer interrupt to int vet 8, which is double fault in the vector table. The double fault normally pushes an error code 0, the ISR is expecting the error code but the timer interrupt does not push an error code thereby screwing up the interrupt stack completely. The kernel runs normally after "sti" after changing the int 8 vector to just "iretq". (Remapping the PIC: http://wiki.osdev.org/I_Cant_Get_Interrupts_Working#I.27m_receiving_EXC9_instead_of_IRQ1_when_striking_a_key_.3F.21 ). Oh FML, hours wasted..
