From eb952c6bce53b5389c41ffc3698594cb43b5aeb9 Mon Sep 17 00:00:00 2001 From: Suzuki K Poulose Date: Thu, 24 Oct 2019 14:47:50 +0200 Subject: [PATCH] arm64: Documentation: cpu-feature-registers: Remove RES0 fields [ Upstream commit 847ecd3fa311cde0f10a1b66c572abb136742b1d ] Remove the invisible RES0 field entries from the table, listing fields in CPU ID feature registers, as : 1) We are only interested in the user visible fields. 2) The field description may not be up-to-date, as the field could be assigned a new meaning. 3) We already explain the rules of the fields which are not visible.
