+/* Some architectures have irregular system call names in
+ <asm/unistd.h>. glibc assumes that system call numbers start with
+ __NR_* and lists the system calls under proper names in
+ <arch-syscall.h>.
+
+ During consistency tests, <fixup-asm-unistd.h> is included after
+ the kernel's <asm/unistd.h>, to introduce aliases as necessary to
+ match the glibc definitions in <arch-syscall.h>.
+
+ Most architectures do not need these fixups, so the default header
+ is empty. */
