ff2e2937a5 Kernel: Remove offset from OpenFileDescriptor
This is now handled on the libc side. There might be reasons to
have it in kernel side, but for simplicity's sake I'm moving it
to libc for now :)

512be884ed Kernel: Add barebones GeneralAllocator for >4096B 2023-05-08 22:10:49 +03:00
b0ec0f1a1a Kernel: We add FixedWidthAllocators on demand
On SYS_ALLOC we will add a new FixedWidthAllocator if the old ones
are already full or we don't have one with proper size. This allows
arbitary number of allocations as long as you have enough memory
available :)

Next I will be writing a general allocator for allocations larger
than 4096 bytes which should make SYS_ALLOC syscall complete :)

12e42f40c5 Kernel/LibC: add free function for FixedWidthAllocator
I have to rework the syscall API and allocators in process. For
now this works well enough :)

bcfd838131 Kernel: Add basic fixed width allocator for userspace
We have to move process stacks to the general heap and maybe map
kernel to higher half.
