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

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.
