---------------------------

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, and ARM64_ILP32 - support of ILP32 ABI (see following
patches). COMPAT indicates that one of them or both is enabled.

Where needed, CONFIG_COMPAT is changed over to use CONFIG_AARCH32_EL0
instead.
