2024-05-01kernel: vm_map: Ensure mmap len is always alignedIan Moffett
Physical memory pages to be allocated is 'len / GRANULE'. Previously, if 'len' was less than the machine page-size, the amount of pages to allocate would be 0 causing the map to fail. Signed-off-by: Ian Moffett <ian@osmora.org>

2024-04-22kernel: vm_map: Fix anon map bugIan Moffett
We should allocate physical memory before we map so the address returned isn't 0. We should also set the virtual memory object for the mapping. Signed-off-by: Ian Moffett <ian@osmora.org>
