[PATCH] mm: mminit_loglevel cannot be __meminitdata anymore

[PATCH] mm: mminit_loglevel cannot be __meminitdata anymore

[Marcin Slusarz]

mminit_loglevel is now used from mminit_verify_zonelist <- build_all_zonelists <-

1. online_pages <- memory_block_action <- memory_block_change_state <- store_mem_state (sys handler)
2. numa_zonelist_order_handler (proc handler)

so it cannot be annotated __meminit - drop it

fixes following section mismatch warning:
WARNING: vmlinux.o(.text+0x71628): Section mismatch in reference from the function mminit_verify_zonelist() to the variable .meminit.data:mminit_loglevel
The function mminit_verify_zonelist() references
the variable __meminitdata mminit_loglevel.
This is often because mminit_verify_zonelist lacks a __meminitdata
annotation or the annotation of mminit_loglevel is wrong.
