Robin Burchell	0dc9af5f7e	Add clang-format file ... Also run it across the whole tree to get everything using the One True Style. We don't yet run this in an automated fashion as it's a little slow, but there is a snippet to do so in makeall.sh.	2019-05-28 17:31:20 +02:00
Andreas Kling	7afc0fb9c8	Kernel: Forked children should inherit their RangeAllocator by copy. ... Otherwise we'll start handing out addresses that are very likely already in use by existing ranges.	2019-05-22 13:24:28 +02:00
Andreas Kling	87b54a82c7	Kernel: Let Region keep a Range internally.	2019-05-17 04:32:08 +02:00
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
