apio	37bbc04719	Heap: Fix GPF caused when making many small allocations ... Apparently space was too tight to split(), but we did it anyways, corrupting the next block. This patch fixes this behavior.	2023-02-17 22:47:15 +01:00

apio	586ca19b62	Add a VERY BASIC and hacky way of allocating memory from userspace ... Only supports one-page allocations and doesn't have libc wrappers, which means it has to be invoked using syscall().	2023-01-11 23:02:42 +01:00
