James Morse 1b568dfec3 arm64: errata: Hide CTR_EL0.DIC on systems affected by Neoverse-N1 #1542419 ... [ Upstream commit 05460849c3b51180d5ada3373d0449aea19075e4 ] Cores affected by Neoverse-N1 #1542419 could execute a stale instruction when a branch is updated to point to freshly generated instructions. To workaround this issue we need user-space to issue unnecessary icache maintenance that we can trap. Start by hiding CTR_EL0.DIC.
