#     powerpc/kasan: fix early boot failure on PPC32
#     
#     Due to commit 4a6d8cf90017 ("powerpc/mm: don't use pte_alloc_kernel()
#     until slab is available on PPC32"), pte_alloc_kernel() cannot be used
#     during early KASAN init.
#     
#     Fix it by using memblock_alloc() instead.
#     
#     Fixes: 2edb16efc899 ("powerpc/32: Add KASAN support")
