/* 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. */
