As it might be of interest. Since uaddr itself is as important as the
containing value, it's alwais printed as comment.

Remove temporary types created for transition from long
to kernel_ulong_t.
Automatically replace kernel_scno_t and kernel_ureg_t with
kernel_ulong_t using
$ git grep -El 'kernel_(scno|ureg)_t' |
xargs sed -ri 's/kernel_(scno|ureg)_t/kernel_ulong_t/g'

Prepare for the change of kernel_ureg_t and kernel_scno_t from
unsigned long to kernel_ulong_t.
* defs.h (PRI_krd, PRI_kru, PRI_krx): New temporary macros.
All users updated.
It is a number which consists of several xlat values, not a structure.
* futex.c (SYS_FUNC(futex)): Modify output of the val3 argument
of the FUTEX_WAKE_OP futex syscall command.
* tests/futex.c (main): Update expected output.

As configure.ac does not check for linux/futex.h, HAVE_LINUX_FUTEX_H is
never defined and therefore the inclusion of <linux/futex.h> guarded by
HAVE_LINUX_FUTEX_H makes no sense.
Moreover, <linux/futex.h> used to have an incorrect definition
of FUTEX_WAIT_BITSET_PRIVATE and FUTEX_WAKE_BITSET_PRIVATE:
since kernel commit v2.6.24-6320-gcd68998 where these definitions
were initially introduced and up to v2.6.31-7082-gf8d1e54 where they
were finally fixed these macros had been incorrectly defined via
FUTEX_WAIT_BITS and FUTEX_WAKE_BITS instead of FUTEX_WAIT_BITSET
and FUTEX_WAKE_BITSET, and these incorrect definitions made their way
into some distributions still in use.
* futex.c [HAVE_LINUX_FUTEX_H]: Remove.
This is analogous to timeout argument omitting in FUTEX_WAKE_BITSET
command.
* futex.c (SYS_FUNC(futex)): Remove common printing of val argument.
Add printing of val argument for all futex commands except
FUTEX_LOCK_PI, FUTEX_UNLOCK_PI, and FUTEX_TRYLOCK_PI.
Use alternate form for printing hexadecimal numbers to avoid confusion.
Use printaddr to print uaddr as the latter is interpreted as a pointer
in all currently supported futex operations.
* futex.c (SYS_FUNC(futex)): Fix formatting of unknown command
argument.
Since obsolete FUTEX_FD command is known and used to have some expected
argument format, print FUTEX_FD using that format.
* futex.c (SYS_FUNC(futex)): Handle FUTEX_FD command.
According to the initial and current (v4.7) kernel implementations,
in FUTEX_WAKE_OP case the compare function does not have
FUTEX_OP_OPARG_SHIFT flag and occupies 4 bits starting with bit 24.
* futex.c (SYS_FUNC(futex)): Do not print FUTEX_OP_OPARG_SHIFT
for 27th bit of val3 in FUTEX_WAKE_OP case.
Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't. This
change fixes the inconsistency by adding missing copyright headers.
It doesn't mean that copyright headers became maintained. In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.
Introduce SYS_FUNC macro to declare and define all syscall parsers.
* Makefile.am (BUILT_SOURCES, CLEANFILES): Add sys_func.h.
(sys_func.h): New rule.
* defs.h (SYS_FUNC_NAME, SYS_FUNC): New macros.
* linux/syscall.h: Include "sys_func.h".
[NEED_UID16_PARSERS]: Use SYS_FUNC to declare uid16 syscall parsers.
Remove other declarations.
* linux/alpha/syscallent.h (160, 161): Add sys_ prefix to osf_statfs
and osf_fstatfs syscall parsers.
* *.c: Use SYS_FUNC to define syscall parsers.
