It used # to work (by chance ?) because CPU wake-up interrupt never comes from # user, so r2 is expected to point to 'current' on return. # # Commit e2fb9f544431 ("powerpc/32: Prepare for Kernel Userspace Access # Protection") broke it even more by clobbering r0 which is not # restored by fast_exception_return either. # # Use r6 instead of r0. This is possible because r3-r6 are restored by # fast_exception_return and only r3-r5 are used for exception arguments. # # For r2 it could be converted back to virtual address, but stay on the # safe side and restore it from the stack instead. It should be live # in the cache at that moment, so loading from the stack should make # no difference compared to converting it from phys to virt. # # Fixes: f7354ccac844 ("powerpc/32: Remove CURRENT_THREAD_INFO and rename TI_CPU") # Fixes: e2fb9f544431 ("powerpc/32: Prepare for Kernel Userspace Access Protection") # Cc: stable@vger.kernel.org # Signed-off-by: Christophe Leroy
