+Subject: [PATCH] Fix missing include in sys/mman.h
+
+Linux commit 746c9398f5ac ("arch: move common mmap flags to
+linux/mman.h") moved a few mmap flags, particularly MAP_PRIVATE, from
+asm/mman.h to linux/mman.h.  This broke klibc's build, which uses
+MAP_PRIVATE.
+
+linux/mman.h includes asm/mman.h, so this commit merely includes
+linux/mman.h instead of asm/mman.h.
