* tests/keyctl.c: Since do_keyctl() has so convoluted calling convention
and keyctl test is so complex, let's try to improve readability a bit
with some conventions regarding do_keyctl() call formatting: arguments
representing single keyctl argument should be put on the separate line,
continuations of arguments related to the same keyctl argument should
have additional indentation and termination 0UL should always be
on a separate line. Also, while we are here, let's add spaces
to two type casts that are missing them.
Enhance runtime detection of struct rtnl_link_stats.rx_nohandler
and struct rtnl_link_stats64.rx_nohandler.
* rtnl_link.c (decode_rtnl_link_stats): Do not accept structure length
greater than min_size but less than sizeof(struct rtnl_link_stats).

greater than min_size but less than sizeof(struct rtnl_link_stats64).

struct ndt_stats than the definition used to build strace.

of struct ndt_stats.ndts_table_fulls field, print the field
when it is available.

The attribute of FRA_TABLE is not just a 32-bit integer, some constants

makes no sense.

signal= specification.
* strace.1.in: Document it.
* tests/qual_inject-syntax.test: Check it.
Introduce "flags" field to struct inject_data and use it instead
of magic rval and signo constants.
Due to layout of struct inject_data, this new field does not change
sizeof(struct inject_data).
* defs.h (INJECT_F_RETVAL, INJECT_F_SIGNAL): New macros.
(INJECT_OPTS_RVAL_DEFAULT): Remove macro.
(struct inject_data): Add "flags" field.

inject_data.flags instead of inject_data.rval and inject_data.signo.
* defs.h (inject_data): New structure.
(struct inject_opts): Replace "signo" and "rval" fields with "data"
field of type "struct inject_data".

Move exiting path out of if (entering(tcp)) { ... return 0; } else,
provide common exit point in v4l2_ioctl handler, use break instead of
return in specific command handlers.

print_v4l2_input, print_v4l2_frmivalenum): Move exiting path out of else
par of the entering(tcp) condition.

move exiting paths out of else branch of entering(tcp) condition.
Return RVAL_DECODED if we can't decode command in order to avoid being
called on exiting.
* dm.c (dm_ioctl): Return RVAL_DECODED instead of 0 if command can't be

I see no reason for not having these definitions for SPARC64 and RISC-V.
Also, borrow the check template from supported_personalities.h.
* syscall.c (update_personality) [defined RISCV, defined SPARC64]
<PERSONALITY_NAMES>: Define it for these architectures.

Apply the same treatment to this script as the one in
v4.18-278-g295cf32.
* copyright-year-gen <year>: Change format to format:%cD, remove --date,
supply output as a -d option argument to date +%Y.
Old git versions (like the one shipped in Debian 8) do not support setting
date format with --date, working this around by processing git log output
with date +%Y.
* main/update_copyright_years.sh (process_file) <first_commit_year,
last_commit_year>: Change format to format:%aD, remove --date, supply
output as a -d option argument to date +%Y.
As Chris Metcalf, the author of v4.7-40-g0b99a8a, told in private, there
is no strong reason for having tile's personality name different from
personality names on other architectures, so let's use spaces instead of
dashes here. And, while we are here, remove duplication of personality
name definitions for various architectures.
* syscall.c (update_personality) [defined TILE]: Change dashes to spaces
in personality names.
* tests/nlattr_rtmsg.c: Include <netinet/in.h> and <arpa/inet.h>.
(LWTUNNEL_ENCAP_NONE, RTA_ENCAP_TYPE): New macros.
(main): Check decoding of RTA_DST, RTA_OIF, RTA_METRICS, RTA_MULTIPATH,
RTA_CACHEINFO, RTA_MFC_STATS, RTA_VIA, and RTA_ENCAP_TYPE.
