50b50e78f6 Remove getarg_klu
After transition from long to kernel_ulong_t we no longer need
tcp->ext_arg, and therefore a function to access it is also no longer
needed.

* defs.h (getarg_klu): Remove prototype.
* util.c (getarg_klu): Remove.
(printargs): Access tcp->u_arg directly
* bjm.c (SYS_FUNC(init_module)): Likewise.
* clone.c (SYS_FUNC(unshare)): Likewise.
* fadvise.c (SYS_FUNC(fadvise64)): Likewise.
* kcmp.c (SYS_FUNC(kcmp)): Likewise.
* kexec.c (SYS_FUNC(kexec_file_load)): Likewise.
* keyctl.c (SYS_FUNC(keyctl)): Likewise.
* lookup_dcookie.c (SYS_FUNC(lookup_dcookie)): Likewise.
* mem.c (do_mprotect): Likewise.
* mq.c (SYS_FUNC(mq_timedsend), SYS_FUNC(mq_timedreceive)): Likewise.
* pkeys.c (SYS_FUNC(pkey_alloc)): Likewise.
* prctl.c (print_prctl_args, SYS_FUNC(prctl), SYS_FUNC(arch_prctl)):
Likewise.

a2485b86e7 Use kernel_ulong_t instead of unsigned long long where appropriate
* defs.h (printaddr_ull): Rename to printaddr_klu, change argument
type from unsigned long long to kernel_ulong_t.  All callers updated.
(getarg_ull): Rename to getarg_klu, change return value type
from unsigned long long to kernel_ulong_t.  All callers updated.
(PRI_kl, PRI_kld, PRI_klu, PRI_klx): New macros.
* bjm.c (SYS_FUNC(init_module)): Print kernel_ulong_t type using
PRI_klu format.
* desc.c (SYS_FUNC(pselect6)): Likewise.
* fadvise.c (SYS_FUNC(fadvise64)): Likewise.
* lookup_dcookie.c (SYS_FUNC(lookup_dcookie)): Likewise.
* mq.c (SYS_FUNC(mq_timedsend), SYS_FUNC(mq_timedreceive)): Likewise.
* kcmp.c (SYS_FUNC(kcmp)): Print kernel_ulong_t type using
PRI_klx format.
* keyctl.c (SYS_FUNC(keyctl)): Likewise.
* pkeys.c (SYS_FUNC(pkey_alloc)): Likewise.
* prctl.c (print_prctl_args, SYS_FUNC(prctl), SYS_FUNC(arch_prctl)):
Print kernel_ulong_t type using PRI_kld, PRI_klu, or PRI_klx format.
* util.c (printaddr_ull): Rename to printaddr_klu, change argument
type from unsigned long long to kernel_ulong_t, print it using
PRI_klx format.
(getarg_ull): Rename to getarg_klu, change return value type
from unsigned long long to kernel_ulong_t, print it using
PRI_klx format.

2c871eb566 fadvise: use getarg_ull for obtaining len argument of fadvise64 syscall
Since its type is size_t, it is 64-bit wide on x32 and special care
should be taken in order to obtain it.

* fadvise.c (SYS_FUNC(fadvise64)): Use getarg_ull for obtaining value
of "len" syscall argument.

11f7093560 fadvise: change printing of len argument to unsigned in fadvise64 syscall
The kernel declares fadvise64 as
long sys_fadvise64(int fd, loff_t offset, size_t len, int advice);

* fadvise.c (SYS_FUNC(fadvise64)): Change conversion specifier from
"%ld" to "%lu" for printing len argument since kernel expects argument
of type size_t.

38a34c9349 Add copyright headers to some files which lack them
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.

429c6775d4 fadvise.c: make use of RVAL_DECODED
* fadvise.c (sys_fadvise64, sys_fadvise64_64): Update for RVAL_DECODED.

a0bd3749fc Declare syscall parsers using SYS_FUNC macro
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.

63f28dd197 file.c: move fadvise64 and fadvise64_64 parsers to a separate file
* fadvise.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* file.c: Move sys_fadvise64, sys_fadvise64_64, and related code
to fadvise.c.
