copy_to_user_page macro is used in mm/memory.c:access_process_vm function. This function is called from ptrace code (POKETEXT, POKEDATA) which write data to memory. Microblaze handle physical address for caches that's why there is virt_to_phys conversion. There is potential one location which can caused the problem on WB system. The important is take a look at write PTRACEs requests (POKE/TEXT, DATA, USR). Note: Majority of Microblaze PTRACE code is moved to generic location in newer kernel version that's why this solution should work on the newest kernel version too. linux/io.h is in cacheflush because of mm/nommu.c Tested on a WB system - hello world debugging.
