Documentation for eBPF helpers can be parsed from bpf.h and eventually
turned into a man page. Commit 6f96674dbd ("bpf: relax constraints on
formatting for eBPF helper documentation") changed the script used to
parse it, in order to allow for different indent style and to ease the
work for writing documentation for future helpers.
The script currently considers that the first tab can be replaced by 6
to 8 spaces. But the documentation for bpf_fib_lookup() uses a mix of
tabs (for the "Description" part) and of spaces ("Return" part), and
only has 5 space long indent for the latter.
We probably do not want to change the values accepted by the script each
time a new helper gets a new indent style. However, it is worth noting
that with those 5 spaces, the "Description" and "Return" part *look*
aligned in the generated patch and in `git show`, so it is likely other
helper authors will use the same length. Therefore, allow for helper
documentation to use 5 spaces only for the first indent level.

There is multiple issues with the genaration of maintainer string
It uses DEBEMAIL and EMAIL enviroment variables, which may contain angle brackets,
creating invalid maintainer strings. The documented KBUILD_BUILD_USER and
KBUILD_BUILD_HOST variables are not used. Undocumented and uncommon NAME
variable is used. Refactor the Maintainer string to:
- use EMAIL or DEBEMAIL directly if they are in form "name <user@host>"
- use KBUILD_BUILD_USER and KBUILD_BUILD_HOST if set before falling
back to autodetection
- no longer use NAME variable or the useless Anonymous string
The logic is switched from multiline if/then/fi statements to compact
shell variable substition commands.

but they are currently much too noisy. So turn off
'graph_child_address', 'graph_port', and 'unique_unit_address' warnings
by default. They can be enabled by building dtbs with W=1.

Running 'test -r' on an awk variable name whose value is an empty
string results in test being run with no arguments, and causes system()
to return 0, which indicates success when used to test values returned
by function calls. This results in code within the if blocks being run
when it should not be.
Instead of testing if a file is accessible and readable via calls to
system("test -r " file), rely on the value returned by getline to perform
this kind of testing. Getline returns -1 on error, with the code within
the while loops not being run.

The bpf syscall and selftests conflicts were trivial
overlapping changes.
The r8169 change involved moving the added mdelay from 'net' into a
different function.
A TLS close bug fix overlapped with the splitting of the TLS state
into separate TX and RX parts. I just expanded the tests in the bug
fix from "ctx->conf == X" into "ctx->tx_conf == X && ctx->rx_conf

The original shell script works, but:
1) it is too slow;
2) it is hard to exclude rejex patterns
Convert it to perl.
Here, the new version is able to check the entire tree in
less than a second (after cached):
real 0m0,284s
user 0m0,668s
sys 0m0,778s
The old version takes more than a minute to complete (also
after cached):
real 1m17,905s
user 0m25,583s
sys 0m55,334s
It also produce less false-positives (if any).
The new script also contains an auto-fix mode.
Usually, file references get lost when they're moved to some other
place and/or renamed to .rst.
Add an experimental mode to auto-fix those.
