Re: [Crash-utility] ppc: work out irq and fix pte translation display

This patch set updates ppc "irq" and PTE translation display of book3e. - Support "irq" command for recent kernel The ppc's "irq" could not work well for recent kernel at all because ppc_init() always made SIZE(irq_desc_t) invalid by itself. And also, "irq" options were not supported entirely. Stash legacy ppc_dump_irq() behind generic_dump_irq() so that "irq" works on recent kernel and follow toward mainline updates lightly by using generic irq functions. - Fix PTE translation for book3e Although book3e uses multiple PTE bits for one attribute, ppc_translate_pte() can not handle such attributes well. And further privilege (kernel) RW protection bit assign of book3e are different from user's ones. Fix and add these translation features in ppc_translate_pte().
