Add a basic kernel heap object. Currently allocation always fails because we don't have a way to allocate a physical page. 2023-05-18 09:46:41 -07:00
Add the ability to copy memory to non resident process. Use/Test this by loading the user space elf from the kernel process before it starts rather than as a part of the first thread. This simplifies thread start a fair bit. 2023-05-30 01:27:47 -07:00			`uint64_t AllocatePageIfNecessary(uint64_t addr, uint64_t cr3 = 0);`
