The netdev-FAQ page in the italian translation was creted to avoid
having broken links. With the evolution of the documentation this was
not referenced anymore, but the page never removed.

The canonical way to add a heading to the ToC is to use :caption:.
Do that.
Let's also move the introduction to the top of the document to be
consistent with most other documents.

Jiri Kosina, Jonathan Corbet, and Willy Tarreau all expressed a desire
to move this document under process/.
Create a new section for security issues in the index and group it with
embargoed-hardware-issues.
I'm doing this at the start of the series to make all the subsequent
changes show up in 'git blame'.
Existing references were updated using:
git grep -l security-bugs ':!Documentation/translations/' | xargs sed -i 's|admin-guide/security-bugs|process/security-bugs|g'
git grep -l security-bugs Documentation/translations/ | xargs sed -i 's|Documentation/admin-guide/security-bugs|Documentation/process/security-bugs|g'
git grep -l security-bugs Documentation/translations/ | xargs sed -i '/Original:/s|\.\./admin-guide/security-bugs|\.\./process/security-bugs|g'
Notably, the page is not moved in the translations (due to my lack of
knowledge of these languages), but the translations have been updated
to point to the new location of the original document where these
references exist.

These char PCMCIA drivers are buggy[1] and receive only minimal care. It
was concluded[2], that we should try to remove most pcmcia drivers
completely. Let's start with these char broken one.
Note that I also removed a UAPI header: include/uapi/linux/cm4000_cs.h.
I found only coccinelle tests mentioning some ioctl constants from that
file. But they are not actually used. Anyway, should someone complain,
we may reintroduce the header (or its parts).

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer updates from Thomas Gleixner:
"Updates for timers, timekeeping and drivers:
Core:
- The timer_shutdown[_sync]() infrastructure:
Tearing down timers can be tedious when there are circular
dependencies to other things which need to be torn down. A prime
example is timer and workqueue where the timer schedules work and
the work arms the timer.
What needs to prevented is that pending work which is drained via
destroy_workqueue() does not rearm the previously shutdown timer.
Nothing in that shutdown sequence relies on the timer being
functional.
The conclusion was that the semantics of timer_shutdown_sync()
should be:
- timer is not enqueued
- timer callback is not running
- timer cannot be rearmed
Preventing the rearming of shutdown timers is done by discarding
rearm attempts silently.
A warning for the case that a rearm attempt of a shutdown timer is
detected would not be really helpful because it's entirely unclear
how it should be acted upon. The only way to address such a case is
to add 'if (in_shutdown)' conditionals all over the place. This is
error prone and in most cases of teardown not required all.
- The real fix for the bluetooth HCI teardown based on
timer_shutdown_sync().
A larger scale conversion to timer_shutdown_sync() is work in
progress.
- Consolidation of VDSO time namespace helper functions
- Small fixes for timer and timerqueue
Drivers:
- Prevent integer overflow on the XGene-1 TVAL register which causes
an never ending interrupt storm.
- The usual set of new device tree bindings
- Small fixes and improvements all over the place"

del_timer_sync() does not return the number of times it tried to delete the
timer which rearms itself. It's clearly documented:
The function returns whether it has deactivated a pending timer or not.
This part of the documentation is from 2003 where del_timer_sync() really
returned the number of deletion attempts for unknown reasons. The code
was rewritten in 2005, but the documentation was not updated.

The last user was removed in 5.1 in
commit 08300f4402ab ("a.out: remove core dumping support")
but this is part of the UAPI headers, so this may want to either wait
until a.out is removed entirely, or be removed from the magic number doc
and silently remain in the header

value

The entire file blames back to the start of git
(minus whitespace from the RST translation and a typo fix):
* there are changelog comments for March 1994 through to Linux 2.5.74
* struct tty_ldisc is two pointers nowadays, so naturally no magic
* GDA_MAGIC is defined but unused, and it's been this way
since start-of-git
* M3_CARD_MAGIC isn't defined, because
commit d56b9b9c464a ("[PATCH] The scheduled removal of some OSS
drivers") removed the entire driver in 2006
* CS_CARD_MAGIC likewise since
commit b5d425c97f7d ("more scheduled OSS driver removal") in 2007
* KMALLOC_MAGIC and VMALLOC_MAGIC were removed in
commit e38e0cfa48ac ("[ALSA] Remove kmalloc wrappers"),
six months after start of git
* SLAB_C_MAGIC has never even appeared in git
(removed in 2.4.0-test3pre6)
magic-number.rst is a low-value historial relic at best and
misleading cruft at worst, so start with cleaning out ones that only
appear therein
