UserspaceEmulator: Implement a proper VM allocator This patch brings Kernel::RangeAllocator to UserspaceEmulator in a slightly simplified form. It supports the basic three allocation types needed by virt$mmap(): allocate_anywhere, allocate_specific, and allocate_randomized. Porting virt$mmap() and virt$munmap() to use the allocator makes UE work correctly once again. :^) 2021-02-06 19:08:51 -03:00			`, m_range(Range { VirtualAddress { base }, size })`
