All checks in ipa_table_validate_build() are computed at build time, so build that unconditionally. In ipa_table_valid() calls to ipa_table_valid_one() are missing the IPA pointer parameter is missing in (a bug that shows up only when IPA_VALIDATE is defined). Don't bother checking whether hashed table memory regions are valid if hashed tables are not supported. With those things fixed, have these table validation functions built unconditionally (not dependent on IPA_VALIDATE). Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.
