    2021-05-01  Andrew John Hughes  <gnu_andrew at member.fsf.org>

        Bump aarch32 to jdk8u292-ga-aarch32-20210423.
        * Makefile.am:
        (ICEDTEA_PATCHES): Apply AArch64 part of
        JDK-8158260/PR2991/RH1341258 to AArch32 port
        builds as well, now AArch64 port is upstream
        and thus part of the AArch32 repository too.
        * hotspot.map.in: Bump aarch32 to
        * patches/hotspot/aarch32/8158260-pr2991-rh1341258-aarch64.patch:
        Symlink to Shenandoah version.
