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).

This commit 7d2078310c ("dt-bindings: arm: move cpu-capacity to a
shared loation") updates some references about capacity-dmips-mhz
property in this document.
The list of architectures using capacity-dmips-mhz omits RISC-V, so
supplements it here.

There are only a handful of users of gpio_export() and
related functions.
As these are just wrappers around the modern gpiod_export()
helper, remove the wrappers and open-code the gpio_to_desc
in all callers to shrink the legacy API.

RISC-V uses the same generic topology code as arm64 & while there
currently exists no binding for cpu-capacity on RISC-V, the code paths
can be hit if the property is present.
Move the documentation of cpu-capacity to a shared location, ahead of
defining a binding for capacity-dmips-mhz on RISC-V. Update some
references to this document in the process.

The canonical location for the tracefs filesystem is at /sys/kernel/tracing.
But, from Documentation/trace/ftrace.rst:
Before 4.1, all ftrace tracing control files were within the debugfs
file system, which is typically located at /sys/kernel/debug/tracing.
For backward compatibility, when mounting the debugfs file system,
the tracefs file system will be automatically mounted at:
/sys/kernel/debug/tracing
Many parts of Documentation still reference this older debugfs path, so
let's update them to avoid confusion.

Sphinx by default, reducing the number of other dependencies that need to
be installed. It also (IMO) produces a cleaner and more readable result.

- 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

In order to make sure that a timer is not re-armed after it is stopped
before freeing, a new shutdown state is added to the timer code. The API
timer_shutdown_sync() and timer_shutdown() must be called before the
object that holds the timer can be freed.
Update the documentation to reflect this new workflow.

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.

Start the process of translating kernel documentation to Spanish. Create
directory sp_SP/ instead of es_ES/ (diverging from format of prior
translated directories) since this directory should accept any dialects of
Spanish. Include an index and a disclaimer, following the approach of
prior translations. Add Carlos Bilbao as MAINTAINER of this effort.

Declaration is '.. c:function:: ktime_t ktime_get( void )'.

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

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 d56b9b9c46 ("[PATCH] The scheduled removal of some OSS
drivers") removed the entire driver in 2006
* CS_CARD_MAGIC likewise since
commit b5d425c97f ("more scheduled OSS driver removal") in 2007
* KMALLOC_MAGIC and VMALLOC_MAGIC were removed in
commit e38e0cfa48 ("[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

grep MAGIC Documentation/process/magic-number.rst | while read -r mag _;
do git grep -wF "$mag" | grep -vq '^Documentation.*magic-number.rst:' ||

"Most of the MM queue. A few things are still pending.
Liam's maple tree rework didn't make it. This has resulted in a few
other minor patch series being held over for next time.
Multi-gen LRU still isn't merged as we were waiting for mapletree to

later reintroduce mapletree, with a view to hopefully getting both
into 6.1-rc1.

understand problems with device drivers and has been part
of Qualcomm's vendor kernels for many years.
- A patch from Sebastian Siewior to rework the handling of
IRQ stacks in softirqs across architectures, which is
needed for enabling PREEMPT_RT.
- The last patch to remove the CONFIG_VIRT_TO_BUS option and
some of the code behind that, after the last users of this
old interface made it in through the netdev, scsi, media and

and discussed a lot.
- potential error path cleanup fixes
- deferred driver probe cleanups
- firmware loader cleanups and tweaks

I noticed that there are some Chinese words that can be more accurate.
So I fix them as follows.
首先，英文原文中的"release" 在这个语境下
是物理页面“释放”的意思，而不是“发布”。
其次，标准表的第一列和第二列，
表达的是“长短键”的意思，第一列是“短键”，
而第二列是“长键”。这样翻译或会更清晰一些。

All architecture-independent users of virt_to_bus() and bus_to_virt()
have been fixed to use the dma mapping interfaces or have been
removed now. This means the definitions on most architectures, and the
CONFIG_VIRT_TO_BUS symbol are now obsolete and can be removed.
The only exceptions to this are a few network and scsi drivers for m68k
Amiga and VME machines and ppc32 Macintosh. These drivers work correctly
with the old interfaces and are probably not worth changing.
On alpha and parisc, virt_to_bus() were still used in asm/floppy.h.
alpha can use isa_virt_to_bus() like x86 does, and parisc can just
open-code the virt_to_phys() here, as this is architecture specific
code.
I tried updating the bus-virt-phys-mapping.rst documentation, which
started as an email from Linus to explain some details of the Linux-2.0
driver interfaces. The bits about virt_to_bus() were declared obsolete
backin 2000, and the rest is not all that relevant any more, so in the
end I just decided to remove the file completely.

Add some basic documentation (zh_CN version) for LoongArch. LoongArch is
a new RISC ISA, which is a bit like MIPS or RISC-V. LoongArch includes a
reduced 32-bit version (LA32R), a standard 32-bit version (LA32S) and a
64-bit version (LA64).
