linux-toradex.git/arch/microblaze/include/asm/uaccess.h, branch v2.6.32 Linux kernel for Apalis and Colibri modules microblaze: Fix put_user macro for 64bits arguments 2009-07-27T05:39:54+00:00 Michal Simek monstr@monstr.eu 2009-07-13T14:46:54+00:00 7bcb63b21327427b130edeb6e6ad44ee260b3043 For 64bits arguments gcc caused that put_user macro works with wrong value because of optimalization. Adding volatile caused that gcc not optimized it. It is possible to use (as Blackfin do) two put_user macros with 32bits arguments but there is one more instruction which is due to duplication zero return value which is called put_user_asm macro.

It is possible to use (as Blackfin do) two put_user
macros with 32bits arguments but there is one more
instruction which is due to duplication zero return
value which is called put_user_asm macro.
