#     powerpc/32s: Fix kasan_early_hash_table() for CONFIG_VMAP_STACK
#     
#     On book3s/32 CPUs that are handling MMU through a hash table,
#     MMU_init_hw() function was adapted for VMAP_STACK in order to
#     handle virtual addresses instead of physical addresses in the
#     low level hash functions.
#     
#     When using KASAN, the same adaptations are required for the
#     early hash table set up by kasan_early_hash_table() function.
#     
#     Fixes: cd08f109e262 ("powerpc/32s: Enable CONFIG_VMAP_STACK")
