powerpc: Add esr as a synonym for pt_regs.dsisr

2021-08-26T11:21:06Z

Create an anonymous union for dsisr and esr regsiters, we can reference esr to get the exception detail when CONFIG_4xx=y or CONFIG_BOOKE=y. Otherwise, reference dsisr. This makes code more clear.

powerpc/4xx: Move machine_check_4xx() into platforms/4xx

2017-08-10T13:31:30Z

Now that we have 4xx platform directory we can move the 4xx machine check handler in there. Again we drop get_mc_reason() and replace it with regs->dsisr directly (which is actually SPRN_ESR). Signed-off-by: Michael Ellerman
