Show tid or pid of iterators if giving an argument of tid or pid
For example, the command `bpftool link list` may list following
lines.
1: iter prog 2 target_name bpf_map
2: iter prog 3 target_name bpf_prog
33: iter prog 225 target_name task_file tid 1644
pids test_progs(1644)
Link 33 is a task_file iterator with tid 1644. For now, only targets
of task, task_file and task_vma may be with tid or pid to filter out
tasks other than those belonging to a process (pid) or a thread (tid).

Show information of iterators in the respective files under
/proc/<pid>/fdinfo/.
For example, for a task file iterator with 1723 as the value of tid
parameter, its fdinfo would look like the following lines.
pos: 0
flags: 02000000
mnt_id: 14
ino: 38
link_type: iter
link_id: 51
prog_tag: a590ac96db22b825
prog_id: 299
target_name: task_file
task_type: TID
tid: 1723
This patch add the last three fields. task_type is the type of the
task parameter. TID means the iterator visit only the thread
specified by tid. The value of tid in the above example is 1723. For
the case of PID task_type, it means the iterator visits only threads
of a process and will show the pid value of the process instead of a
tid.

Allow creating an iterator that loops through resources of one
thread/process.
People could only create iterators to loop through all resources of
files, vma, and tasks in the system, even though they were interested
in only the resources of a specific task or process. Passing the
additional parameters, people can now create an iterator to go
through all resources or only the resources of a task.

V=1 (verbose build) shows commands executed by Make, but it may cause
misunderstanding.
For example, the following command shows the outstanding error message.
$ make V=1 INSTALL_PATH=/tmp install
test -e include/generated/autoconf.h -a -e include/config/auto.conf || ( \
echo >&2; \
echo >&2 " ERROR: Kernel configuration is invalid."; \
echo >&2 " include/generated/autoconf.h or include/config/auto.conf are missing.";\
echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it."; \
echo >&2 ; \
/bin/false)
unset sub_make_done; ./scripts/install.sh
It is not an error. Make just showed the recipe lines it has executed,
but people may think that 'make install' has failed.
Likewise, the combination of V=1 and O= shows confusing
"*** The source tree is not clean, please run 'make mrproper'".

This commit merges them.

1) build obj-y and obj-m objects
2) link vmlinux.o
3) modpost for vmlinux
4) link vmlinux
5) modpost for modules
6) link modules (*.ko)
The build steps 1) through 6) are serialized, that is, modules are
built after vmlinux. You do not get benefits of parallel builds when
scripts/link-vmlinux.sh is being run.
New build flow
==============
1) build obj-y and obj-m objects
2) link vmlinux.o
3) modpost for vmlinux and modules
4a) link vmlinux
4b) link modules (*.ko)
In the new build flow, modpost is invoked just once.
vmlinux and modules are built in parallel. One exception is

On arm32, the configuration options to specify the kernel command line
type depend on ATAGS. However, the actual CMDLINE cofiguration option
does not depend on ATAGS, and the code that handles this is not specific
to ATAGS (see drivers/of/fdt.c:early_init_dt_scan_chosen()).
Hence users who desire to override the kernel command line on arm32 must
enable support for ATAGS, even on a pure-DT system. Other architectures
(arm64, loongarch, microblaze, nios2, powerpc, and riscv) do not impose
such a restriction.
Hence drop the dependency on ATAGS.

On older platforms that boot an image with an appended DTB, or where
the boot loader has no support for updating chosen/bootargs, it is
common to rely on CMDLINE_FORCE.
While a fixed command line can make the kernel unbootable on other
platforms, it is not guaranteed to cause that. E.g. all Renesas boards
use the same chosen/bootargs in upstream DTS, which works fine if your
DHCP server hands out proper nfsroot parameters.

According to s5k6a3 driver code, the reset line for the chip appears to
be active low. This also matches the typical polarity of reset lines in
general. Let's fix it up as having correct polarity in DTS is important
when the driver will be switched over to gpiod API.
