From ddac5cb2d95774cd019bfaf93c54ffd921095fea Mon Sep 17 00:00:00 2001 From: Juan Quintela Date: Tue, 14 Jan 2020 12:24:09 +0100 Subject: [PATCH] multifd: Be consistent about using uint64_t MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We transmit ram_addr_t always as uint64_t. Be consistent in its use (on 64bit system, it is always uint64_t problem is 32bits).
