+Subject: [PATCH] configure.ac: add option --enable-kernel-64-userland-32
+
+The ebtables build system seems to assume that 'sparc64' is the
+only case where KERNEL_64_USERSPACE_32 is relevant, but this is not true.
+This situation can happen on many architectures, especially in embedded
+systems. For example, an Aarch64 processor with kernel in 64-bit but
+userland build for 32-bit Arm. Or a 64-bit MIPS Octeon III processor, with
+userland running in the 'n32' ABI.
+
+While it is possible to set CFLAGS in the environment when calling the
+configure script, the caller would need to know to not only specify
+KERNEL_64_USERSPACE_32 but also the EBT_MIN_ALIGN value.
+
+Instead, add a configure option. All internal details can then be handled by
+the configure script.
