+Subject: [PATCH] Fix RISC-V vfork build with Linux 5.3 kernel headers.
+
+Building glibc for RISC-V with Linux 5.3 kernel headers fails because
+<linux/sched.h>, included in vfork.S for CLONE_* constants, contains a
+structure definition not safe for inclusion in assembly code.
+
+All other architectures already avoid use of that header in vfork.S,
+either defining the CLONE_* constants locally or embedding the
+required values directly in the relevant instruction, where they
+implement vfork using the clone syscall (see the implementations for
+aarch64, ia64, mips and nios2).  This patch makes the RISC-V version
+define the constants locally like the other architectures.
+
+Tested build for all three RISC-V configurations in
+build-many-glibcs.py with Linux 5.3 headers.
+
+	* sysdeps/unix/sysv/linux/riscv/vfork.S: Do not include
+	<linux/sched.h>.
+	(CLONE_VM): New macro.
+	(CLONE_VFORK): Likewise.
+
+(cherry picked from commit 8cacbcf4a984ccac24efedb795d9c8a7f149d17b)
