From: Xiongwei Song <redacted> When CONFIG_4xx=y or CONFIG_BOOKE=y, currently in code we reference dsisr to get interrupt reasons and reference dar to get excepiton address. However, in reference manuals, esr is used for interrupt reasons and dear is used for excepiton address, so the patchset changes dsisr -> esr, dar -> dear for CONFIG_4xx=y or CONFIG_BOOKE=y. [...]
