From 9cf18e1dd74cd0061d58ac55029784ca3dd88f6a Mon Sep 17 00:00:00 2001 From: Amerigo Wang Date: Tue, 15 Dec 2009 16:47:36 -0800 Subject: ipc: HARD_MSGMAX should be higher not lower on 64bit We have HARD_MSGMAX lower on 64bit than on 32bit, since usually 64bit machines have more memory than 32bit machines. Making it higher on 64bit seems reasonable, and keep the original number on 32bit. Acked-by: Serge E.
