Hi,
The restartable sequence code needs a __get_user for u64 types.
arm32. Although a get_user() is implemented, the architecture
lacks support for 8 bytes __get_user().
Do you guys recommend extending __get_user_err() to do two
__get_user_asm_word() to read it through a temporary union,
or do you have other approaches in mind ?
Thanks,
Mathieu
