Function axhal::mem::phys_to_virt

pub const fn phys_to_virt(paddr: PhysAddr) -> VirtAddr

Converts a physical address to a virtual address.

It assumes that there is a linear mapping with the offset PHYS_VIRT_OFFSET, that maps all the physical memory to the virtual space at the address plus the offset. So we have vaddr = paddr + PHYS_VIRT_OFFSET.
