Mark Rutland cf99a48dce arm64: introduce common ESR_ELx_* definitions ... Currently we have separate ESR_EL{1,2}_* macros, despite the fact that the encodings are common. While encodings are architected to refer to the current EL or a lower EL, the macros refer to particular ELs (e.g. ESR_ELx_EC_DABT_EL0). Having these duplicate definitions is redundant, and their naming is misleading. This patch introduces common ESR_ELx_* macros that can be used in all cases, in preparation for later patches which will migrate existing users over. Some additional cleanups are made in the process: * Suffixes for particular exception levelts (e.g. _EL0, _EL1) are replaced with more general _LOW and _CUR suffixes, matching the architectural intent. * ESR_ELx_EC_WFx, rather than ESR_ELx_EC_WFI is introduced, as this EC encoding covers traps from both WFE and WFI. Similarly, ESR_ELx_WFx_ISS_WFE rather than ESR_ELx_EC_WFI_ISS_WFE is introduced. * Multi-bit fields are given consistently named _SHIFT and _MASK macros. * UL() is used for compatiblity with assembly files. * Comments are added for currently unallocated ESR_ELx.EC encodings. For fields other than ESR_ELx.EC, macros are only implemented for fields for which there is already an ESR_EL{1,2}_* macro.
