From 454d0a68e7983b33b7601e95565b4fc17939328c Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Fri, 2 Aug 2019 20:56:46 +1000 Subject: [PATCH] powerpc/64s/exception: remove 0xb00 handler This vector is not used by any supported processor, and has been implemented as an unknown exception going back to 2.6. There is nothing special about 0xb00, so remove it like other unused vectors.
