[PATCH v3 06/26] arm64/mte: Standardise GMID field name definitions

Mark Brown broonie at kernel.org
Thu Jun 9 10:08:40 PDT 2022


Usually our defines for bitfields in system registers do not include a SYS_
prefix but those for GMID do. In preparation for automatic generation of
defines remove that prefix. No functional change.
