vm_kern: Add kmem_alloc_aligned_table
This function allows to map a table in a memory page,
using its physical address,aligning the start of the page with the start of the table
*vm/vm_kern.c (kmem_alloc_aligned_table): New function. Returns a reference for the virtual address of the table.
*vm/vm_kern.h (kmem_alloc_aligned_table): New prototype
