#     powerpc/highmem: Change BUG_ON() to WARN_ON()
#     
#     In arch/powerpc/mm/highmem.c, BUG_ON() is called only when
#     CONFIG_DEBUG_HIGHMEM is selected, this means the BUG_ON() is not vital
#     and can be replaced by a a WARN_ON().
#     
#     At the same time, use IS_ENABLED() instead of #ifdef to clean a bit.
