From: Andrew Pinski <[email protected]> In this patchset ILP32 ABI support is added. Additionally to AARCH32, which is binary-compatible with ARM, ILP32 is (mostly) ABI-compatible.
>From now, AARCH32_EL0 (former COMPAT) config option means the support of AARCH32 userspace, ARM64_ILP32 - support of ILP32 ABI (see next patches), and COMPAT indicates that one of them, or both, is enabled.
