ChangeLog:
2017-07-26 Andrew John Hughes <gnu_andrew at member.fsf.org>
Bump shenandoah to
aarch64-shenandoah-jdk8u141-b16-shenandoah-merge-2017-07-26
* patches/hotspot/shenandoah/8175887-pr3415.patch:
Removed as applied upstream.
* Makefile.am:
(ICEDTEA_PATCHES): Move patch that still
applies to AArch32, but not Shenandoah, to the AArch32-only
block. Add PR3224 fix in the Shenandoah-only block.
* NEWS: Updated.
* hotspot.map.in: Bump shenandoah to
aarch64-shenandoah-jdk8u141-b16-shenandoah-merge-2017-07-26.
* patches/hotspot/aarch32/8175887-pr3415.patch,
Patch is still needed for AArch32 so replace symlink
with the actual patch from patches/hotspot/shenandoah.
* patches/hotspot/shenandoah/pr3224.patch:
Shenandoah update broke compilation without precompiled
headers again. This patch fixes it.
