Properly set r1 before activating MMU on syscall too # # We need r1 to be properly set before activating MMU, otherwise any new # exception taken while saving registers into the stack in syscall # prologs will use the user stack, which is wrong and will even lockup # or crash when KUAP is selected. # # Do that by switching the meaning of r11 and r1 until we have saved r1 # to the stack: copy r1 into r11 and setup the new stack pointer in r1. # To avoid complicating and impacting all generic and specific prolog # code (and more), copy back r1 into r11 once r11 is save onto # the stack. # # We could get rid of copying r1 back and forth at the cost of rewriting # everything to use r1 instead of r11 all the way when CONFIG_VMAP_STACK # is set, but the effort is probably not worth it for now. # # Fixes: da7bb43ab9da ("powerpc/32: Fix vmap stack -
