From: Nicholas Piggin Date: Fri, 2 Aug 2019 10:56:42 +0000 (+1000) Subject: powerpc/64s/exception: Fix DAR load for handle_page_fault error case X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c31f7134dc53f7020b3d49e846d1b950a761e324;p=openwrt%2Fstaging%2Fblogic.git powerpc/64s/exception: Fix DAR load for handle_page_fault error case This buglet goes back to before the 64/32 arch merge, but it does not seem to have had practical consequences because bad_page_fault does not use the 2nd argument, but rather regs->dar/nip.
