Your patch actually contains 2 things - Support for Cavium Octeon instructions - Support for MIPS64 userland The 2 things are independent and should be submitted as two different patches. Also the support for Octeon instruction should not depend on a global variable, but should use the CPU features system already available. Please have a look at target-mips/translate_init.c to see how it works. -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net
