#     powerpc: Fix __clear_user() with KUAP enabled
#     
#     The KUAP implementation adds calls in clear_user() to enable and disable
#     access to userspace memory. However, it doesn't add these to
#     __clear_user(), which is used in the ptrace regset code.
#     
#     As there's only one direct user of __clear_user(), and the time taken to
#     set the AMR for KUAP purposes is going to dominate the cost of a quick
#     access_ok(), there's not much point having a separate path.
#     
#     Rename __clear_user() to clear_user_asm(), and make __clear_user() just
#     call clear_user().
#
