Marcelo Henrique Cerri 75d02bceb2 proc: Avoid mixing integer types in mem_rw() ... [ Upstream commit d238692b4b ] Use size_t when capping the count argument received by mem_rw(). Since count is size_t, using min_t(int, ...) can lead to a negative value that will later be passed to access_remote_vm(), which can cause unexpected behavior. Since we are capping the value to at maximum PAGE_SIZE, the conversion from size_t to int when passing it to access_remote_vm() as "len" shouldn't be a problem.
