+Subject: [PATCH 17/28] Fix powerpc64 ELFv2 big-endian struct-passing ABI
+
+The requirements here are not "ELFv1" requirements, but big-endian
+requirements, as the extension or non-extension of the argument is
+necessary to put the argument in the correct half of the register.
+Parameter passing in the ELFv2 ABI needs these same transformations.
+Since this code makes no difference on little-endian machines, simplify
+it to use the same code path everywhere.

+
+`const LE_I128` needs parentheses to negate the value *before* calling
+`to_le()`, otherwise it doesn't match the operations performed in the
+black-boxed part of the test. This only makes a tangible difference on
+big-endian targets.

+Subject: [PATCH] Re-add aarch64 stuff removed by previous commit
+
+Previous commit
+
+dcff154781e4b3c6ef3a6a4024c73631f52f48cb
+"libc: changes to ppc64le musl branch to support building of rust on Alpine"
+
+has removed stuff from mod.rs and added it to some submodules, but
+missed the aarch64 submodule.
+
+This copies the stuff that that commit added to the x86_64.rs submodule
+and puts it into aarch64.rs.
