    powerpc/32: Add KASAN support · 2edb16ef
    Christophe Leroy authored
    This patch adds KASAN support for PPC32. The following patch
    will add an early activation of hash table for book3s. Until
    then, a warning will be raised if trying to use KASAN on an
    hash 6xx.
    
    To support KASAN, this patch initialises that MMU mapings for
    accessing to the KASAN shadow area defined in a previous patch.
    
    An early mapping is set as soon as the kernel code has been
    relocated at its definitive place.
    
    Then the definitive mapping is set once paging is initialised.
    
    For modules, the shadow area is allocated at module_alloc().
