From: Paul Mackerras Date: Mon, 19 Mar 2018 21:46:12 +0000 (+1100) Subject: powerpc: Book E: Remove unused CPU_FTR_L2CSR bit X-Git-Tag: v5.15~9084^2~72^2~14 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dd0efb3f11cc0adcb4caa192ba09ad802d1fa6c0;p=platform%2Fkernel%2Flinux-starfive.git powerpc: Book E: Remove unused CPU_FTR_L2CSR bit The CPU_FTR_L2CSR bit is never tested anywhere, so let's reclaim the bit. The last usage was removed in 86d63363defc ("powerpc/e500mc: Remove dead L2 flushing code in idle_e500.S") (Jun 2015).
