powerpc/kasan: Fix boot failure with RELOCATABLE && FSL_BOOKE
When enabling CONFIG_RELOCATABLE and CONFIG_KASAN on FSL_BOOKE, the kernel doesn't boot. relocate_init() requires KASAN early shadow area to be set up because it needs access to the device tree through generic functions. Call kasan_early_init() before calling relocate_init() Reported-by: Lexi Shao <shaolexi@huawei.com> Fixes: 2edb16efc899 ("powerpc/32: Add KASAN support") Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/b58426f1664a4b344ff696d18cacf3b3e8962111.1575036985.git.christophe.leroy@c-s.fr
