This one seems convincing argument. ATM do you have any mm_context flag which would you like to incorporate?


I think that this is not what was intended when you added new field in
mm_context_t.

In this patch the MMCF_AARCH32 flag is introduced, where MMCF prefix stands for
mm_context_t flags. And the new flag is used for uprobes code instead of TIF_32BIT.
