Please use make<T> and destroy<T> instead of new and delete
Those are there only for common stuff (in the Luna library) that needs an environment-agnostic way of allocating memory.
new and delete are standard, thus we should use those.

caf6d1563c Kernel: Add a heap memory allocator
This is the first time I've actually dropped liballoc in favor of writing my own implementation.
Usually, malloc() and such looked so complicated that I preferred to let a nice external library do the job.
But I've decided to try writing my own allocator, and now we have heap memory without any 3rd party code!

cb88630d86 Bugfix: Make alloc_at return the start of the virtual memory range instead of the end 2022-11-20 15:11:53 +01:00
af267772f0 Rename MemoryManager::map to map_frames_at
To make it clearer that this API is only intented for mapping contiguous frames of physical memory (for MMIO perhaps?)

d96cb73995 Rename physical "pages" to "frames"
AFAIK, this is the proper naming scheme. "Pages" are virtual, and "frames" physical.
