anna	b4ed811920	mm: refactor page allocator ... This is hopefully the last time in a while that something in the mm subsystem needs a refactor this large. There are two main changes: - The page frame allocator returns a vm_page_t rather than a virtual address. - Data for the slab allocator is now stored in struct vm_page, which means there is no overhead in the slab itself so the space is used in a more efficient manner.	2 years ago

anna	385af1b7ef	mm: refactor page frame allocator ... This is part 3 of the mm subsystem overhaul. The allocator doesn't rely on mutexes anymore and uses individual per-order spinlocks instead. Also, it is aware of multiple memory zones (normal and DMA) as well as emergency reserves. Page bitmaps take up 50 % less overhead now.	3 years ago
anna	d19e665d47	mm: generalize boot allocator ... The boot page frame allocator is now architecture independent. This is part 2 of the mm subsystem refactor.	3 years ago
