profile: Suppress warning about large allocations when profile=1 is specified

Browse Source 
When profile= is used, a large buffer is allocated early at
boot. This can be larger than what the page allocator can
provide so it prints a warning. However, the caller is able to
handle the situation so this patch suppresses the warning.
