Subject[PATCH 2/3] profile: Suppress warning about large allocations when profile=1 is specified
Date
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.
