Andreas Kling	4a6fcfbacf	Kernel: Use a RangeAllocator for kernel-only virtual space allocation too.	2019-05-17 04:02:29 +02:00
Andreas Kling	c414e65498	Kernel: Implement a simple virtual address range allocator. ... This replaces the previous virtual address allocator which was basically just "m_next_address += size;" With this in place, virtual addresses can get reused, which cuts down on the number of page tables created. When we implement ASLR some day, we'll probably have to do page table deallocation, but for now page tables are only deallocated once the process dies.	2019-05-17 03:40:15 +02:00
