powerpc/signal32: Fix erroneous SIGSEGV on RT signal return # # Return of user_read_access_begin() is tested the wrong way, # leading to a SIGSEGV when the user address is valid and likely # an Oops when the user address is bad. # # Fix the test. # # Fixes: 887f3ceb51cd ("powerpc/signal32: Convert do_setcontext[_tm]() to user access block") # Signed-off-by: Christophe Leroy # Signed-off-by:
