Subject: [PATCH] x86: find_early_table_space() cleanup
From: Pekka Enberg <penberg@...helsinki.fi>
Impact: cleanup
The init_memory_mapping() function (and thus find_early_table_space) is called
from only one place on 32-bit. The call-site is in setup_arch() and the 'end'
parameter passed is explicitly set to max_pfn_mapped << PAGE_SHIFT. Therefore,
we can move the find_e820_area() call out of the ifdef.
