[PATCH v2 2/3] powerpc: Stop using init_mem_is_free

From: Christophe Leroy
Date: Sat Sep 25 2021 - 08:24:35 EST


Generic parts of the kernel for instance core_kernel_text()
use 'system_state' to check whether init memory has been
freed.

Do the same and stop using init_mem_is_free.

arch_is_kernel_initmem_freed() is likely going to go away via the mm tree, in that case this patch will void.

v2: Also remove declaration of init_mem_is_free.
