[PATCH] mm/page_alloc.c: variable type of 'progress' should be 'unsigned long'

[<yanfei.xu@xxxxxxxxxxxxx>]

From: Yanfei Xu <yanfei.xu@xxxxxxxxxxxxx>

try_to_free_pages returns the number of pages reclaimed, and the type of
returns is 'unsigned long'. So we should use a matched type for storing
it.
