+Subject: [PATCH 2/2] Valgrind's vgdb extended-remote mode broken on aarch64
+
+At the moment, valgrind doesn't provide the target description XML
+on aarch64: target_xml() in valgrind-low-arm64.c isn't implemented
+yet. But it does advertise it via qXfer:features:read.
+
+Related commit 2d3d477689a688ab mentions: What remains to be done:
+* arm64 xml register description files (allowing shadow registers to be looked at).
+* ptrace invoker : currently disabled for both arm and arm64
+* cpsr transfer to/from gdb to be looked at (see also arm equivalent code)
+
+This patch prevents advertising qXfer:features:read on aarch64 and
+makes valgrind work with gdb-17 in extended-remote mode on aarch64.
