[PATCH] x86: find_early_table_space() cleanup

[Pekka Enberg]

From: Pekka Enberg <penberg@xxxxxxxxxxxxxx>

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.
