Negative micro/nanoseconds values are treated as invalid by kernel
anyway, and in one case (timespec_valid in include/linux/time.h)
it is even checked by conversion to unsigned long.
* print_timespec.c (timespec_fmt): Change tv_sec format to %lld and
tv_nsec format to %llu.

zero_extend_signed_to_ull.

* print_timeval.c (timeval_fmt): Change tv_sec format to %lld and
tv_usec format to %llu.
(print_timeval_t): Cast tv_sec to long long and process tv_nsec with
zero_extend_signed_to_ull.

* defs.h (TIMESPEC_TEXT_BUFSIZE): Update.
* tests/adjtimex.c (main): Change tv_sec printing format to %lld, cast
it to long long; change tv_usec printing format to %llu, process it with
zero_extend_signed_to_ull.
* tests/clock_nanosleep.c (main): Change tv_sec printing format to %lld,
cast it to long long; change tv_nsec printing format to %llu, process it
with zero_extend_signed_to_ull.

This follows the rename of print_timeval_item to print_timeval_utimes.
* defs.h [ALPHA] (print_timeval32_pair): Rename
to print_timeval32_utimes.
* print_timeval.c [ALPHA] (print_timeval32_pair): Likewise.
* utimes.c [ALPHA] (SYS_FUNC(osf_utimes)): Replace print_timeval32_pair
with print_timeval32_utimes.
When the whole pair of struct timeval structures cannot be fetched from
tracee's memory, print the address. This behavior follows the kernel's
that uses copy_from_user for the whole pair, too.
* print_timeval.c (print_timeval_item): Remove.
(print_timeval_pair): Rename to print_timeval_utimes, all callers
updated. Fetch the whole timeval_t array with a single
umove_or_printaddr call.
* tests/futimesat.c (main): Update expected output.
* tests/utimes.c (main): Likewise.
Remove temporary macros created for transition from long
to kernel_ulong_t.
Automatically replace PRI_kr[dux] with PRI_kl[dux] using
$ git grep -l 'PRI_kr[dux]' | xargs sed -ri 's/PRI_kr([dux])/PRI_kl\1/g'
* defs.h (PRI_krd, PRI_kru, PRI_krx): Remove. All users updated.
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'
* kernel_types.h (kernel_scno_t, kernel_ureg_t): Remove.
All users updated.
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.
* defs.h [ALPHA] (sprint_timeval32, print_timeval32,
print_timeval32_pair, print_itimerval32): Change address argument type
from long to kernel_ureg_t.
* desc.c (decode_select): Change the type of tracee address argument
of print_tv_ts and sprint_tv_ts from long to kernel_ureg_t.
* print_timespec.c (print_timespec, sprint_timespec,
print_timespec_utime_pair, print_itimerspec): Change address argument
type from long to kernel_ureg_t.
* print_timeval.c (print_timeval, print_timeval_pair, sprint_timeval,
print_itimerval, print_timeval32, print_timeval32_pair,
print_itimerval32, sprint_timeval32): Likewise.
* print_timeval.c (print_timeval_item): New function.
(print_timeval_pair): Use it as a print_function in print_array call.
* tests/futimesat.c (main): Update to test new behaviour.
* tests/utimes.c (main): Likewise.
* defs.h [ALPHA] (timeval32_t): New type.
[ALPHA] (print_timeval32_t): New prototype.
* print_timeval.c [ALPHA] (timeval32_t): Remove.
[ALPHA] (print_timeval32_t): Remove static keyword.
* printrusage.c [ALPHA] (printrusage32): Use timeval32_t instead
of local definition of struct timeval32. Use print_timeval32_t.
After commit v4.14-136-g151d1d1 that removed the last object common
for timespec and timeval parsers there is no need to keep them all
in a single file.
* print_timespec.c: New file.
* print_timeval.c: Likewise.
* Makefile.am (strace_SOURCES): Add them.
* print_time.c: Move all timespec related code to print_timespec.c.
Move all timeval related code to print_timeval.c.
