powerpc/kernel: Check features don't change after patching Early in boot we binary patch some sections of code based on the CPU and MMU feature bits. But it is a one-time patching, there is no facility for repatching the code later if the set of features change. It is a major bug if the set of features changes after we've done the code patching - so add a check for it. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
