commit 3c26c30fd2a5bdec081384d45e42a7ea4e424846
Author: Samuel Thibault <samuel.thibault@ens-lyon.org>
Date:   Mon Dec 12 00:03:05 2022 +0100

    copy_to/from_phys: fix non-page-aligned case
    
    The vaddr field of the returned map only points to the base address, we
    have to add the offset within the page before reading/writing.
    
    This fixes accessing tasks different from the current task, and
    the user part of ddb backtraces.
