That inline function was simply masking # out the value of r1. # # In that commit, it was changed to using current_stack_pointer() (since # renamed current_stack_frame()), which is a heavier function as it is # an outline assembly function which cannot be inlined and which reads # the content of the stack at 0(r1). # # Convert to using current_stack_pointer for geting r1 and masking out # its value to obtain the base address of the stack pointer as before. # # Fixes: 7306e83ccf5c ("powerpc: Don't use CURRENT_THREAD_INFO to find the stack") # Signed-off-by: Christophe Leroy # Signed-off-by:
