+linux-user mode does not support memfd_create syscall
+
+qemu-x86_66 GIT HEAD fails on a userspace application that requires memfd_create with:
+
+"qemu: Unsupported syscall: 319".
+
+memfd_create support needs to be implemented in QEMU.
+
+Not only qemu-x86_64, but also:
+
+qemu-aarch64 => qemu: Unsupported syscall: 279
+qemu-arm => qemu: Unsupported syscall: 385
+qemu-mips => qemu: Unsupported syscall: 4354
+qemu-mips64 => qemu: Unsupported syscall: 5314
+qemu-powerpc => qemu: Unsupported syscall: 360
+qemu-powerpc64 => qemu: Unsupported syscall: 360
+
+9bdfa4d23f43 linux-user: add memfd_create
