Greg Kroah-Hartman 6e30a66433 driver core: class: remove struct module owner out of struct class
The module owner field for a struct class was never actually used, so
remove it as it is not doing anything at all.

Greg Kroah-Hartman 10a03c36b7 drivers: remove struct module * setting from struct class
There is no need to manually set the owner of a struct class, as the
registering function does it automatically, so remove all of the
explicit settings from various drivers that did so as it is unneeded.

This allows us to remove this pointer entirely from this structure going
forward.

Greg Kroah-Hartman 4a46ac9d64 driver core: class: specify the module owner in __class_register()
There's no need to manually have to set the module owner of a class, the
compiler should do it automatically for you, so add a module * to the
__class_register() function and allow it to set the module owner
automatically.

This will let us move the module pointer out of struct class eventually,
as it should not be embedded in there if we wish for it to be a
read-only structure eventually.

And, funny story, this module pointer isn't even being used for
anything, so while we will keep it around for now, it's not like it even
matters.

Thomas Weißschuh 64414da25b kobject: align stacktrace levels to logging message
Without an explicit level the stacktraces are printed at a default
level.
If this level does not match the one from the logging level it may
happen that the stacktrace is shown without the message or vice versa.

Both these cases are confusing, so make sure the user always sees both,
the message and the stacktrace.

Andy Shevchenko 295209ca7b device property: Clarify description of returned value in some functions
Some of the functions do not provide Return: section on absence of which
kernel-doc complains. Besides that several functions return the fwnode
handle with incremented reference count. Add a respective note to make sure
that the caller decrements it when it's not needed anymore.

While at it, unify the style of the Return: sections.

Saravana Kannan f8fb576658 driver core: Make state_synced device attribute writeable
If the file is written to and sync_state() hasn't been called for the
device yet, then call sync_state() for the device independent of the
state of its consumers.

This is useful for supplier devices that have one or more consumers that
don't have a driver but the consumers are in a state that don't use the
resources supplied by the supplier device.

This gives finer grained control than using the
fw_devlink.sync_state=timeout kernel commandline parameter.

Saravana Kannan ffbe08a8e8 driver core: Add fw_devlink.sync_state command line param
When all devices that could probe have finished probing (based on
deferred_probe_timeout configuration or late_initcall() when
!CONFIG_MODULES), this parameter controls what to do with devices that
haven't yet received their sync_state() calls.

fw_devlink.sync_state=strict is the default and the driver core will
continue waiting on all consumers of a device to probe successfully
before sync_state() is called for the device. This is the default
behavior since calling sync_state() on a device when all its consumers
haven't probed could make some systems unusable/unstable. When this
option is selected, we also print the list of devices that haven't had
sync_state() called on them by the time all devices the could probe have
finished probing.

fw_devlink.sync_state=timeout will cause the driver core to give up
waiting on consumers and call sync_state() on any devices that haven't
yet received their sync_state() calls. This option is provided for
systems that won't become unusable/unstable as they might be able to
save power (depends on state of hardware before kernel starts) if all
devices get their sync_state().

Greg Kroah-Hartman 22fd6153c1 driver core: class: fix block class problem when removing CONFIG_SYSFS_DEPRECATED*
In removing the CONFIG_SYSFS_DEPRECATED and CONFIG_SYSFS_DEPRECATED_V2
config options, I messed up in the __class_register() function and got
the logic incorrect.  Fix this all up by just removing the special case
of a block device class logic in this function, as that is what is
intended.

In testing, this solves the boot problem on my systems, hopefully on
others as well.

Greg Kroah-Hartman 721da5cee9 driver core: remove CONFIG_SYSFS_DEPRECATED and CONFIG_SYSFS_DEPRECATED_V2
CONFIG_SYSFS_DEPRECATED was added in commit 88a22c985e
("CONFIG_SYSFS_DEPRECATED") in 2006 to allow systems with older versions
of some tools (i.e. Fedora 3's version of udev) to boot properly.  Four
years later, in 2010, the option was attempted to be removed as most of
userspace should have been fixed up properly by then, but some kernel
developers clung to those old systems and refused to update, so we added
CONFIG_SYSFS_DEPRECATED_V2 in commit e52eec13cd ("SYSFS: Allow boot
time switching between deprecated and modern sysfs layout") to allow
them to continue to boot properly, and we allowed a boot time parameter
to be used to switch back to the old format if needed.

Over time, the logic that was covered under these config options was
slowly removed from individual driver subsystems successfully, removed,
and the only thing that is now left in the kernel are some changes in
the block layer's representation in sysfs where real directories are
used instead of symlinks like normal.

Because the original changes were done to userspace tools in 2006, and
all distros that use those tools are long end-of-life, and older
non-udev-based systems do not care about the block layer's sysfs
representation, it is time to finally remove this old logic and the
config entries from the kernel.

Linus Torvalds fe15c26ee2 Linux 6.3-rc1 2023-03-05 14:52:03 -08:00
Linus Torvalds 596ff4a09b cpumask: re-introduce constant-sized cpumask optimizations
Commit aa47a7c215 ("lib/cpumask: deprecate nr_cpumask_bits") resulted
in the cpumask operations potentially becoming hugely less efficient,
because suddenly the cpumask was always considered to be variable-sized.

The optimization was then later added back in a limited form by commit
6f9c07be9d ("lib/cpumask: add FORCE_NR_CPUS config option"), but that
FORCE_NR_CPUS option is not useful in a generic kernel and more of a
special case for embedded situations with fixed hardware.

Instead, just re-introduce the optimization, with some changes.

Instead of depending on CPUMASK_OFFSTACK being false, and then always
using the full constant cpumask width, this introduces three different
cpumask "sizes":

 - the exact size (nr_cpumask_bits) remains identical to nr_cpu_ids.

   This is used for situations where we should use the exact size.

 - the "small" size (small_cpumask_bits) is the NR_CPUS constant if it
   fits in a single word and the bitmap operations thus end up able
   to trigger the "small_const_nbits()" optimizations.

   This is used for the operations that have optimized single-word
   cases that get inlined, notably the bit find and scanning functions.

 - the "large" size (large_cpumask_bits) is the NR_CPUS constant if it
   is an sufficiently small constant that makes simple "copy" and
   "clear" operations more efficient.

   This is arbitrarily set at four words or less.

As a an example of this situation, without this fixed size optimization,
cpumask_clear() will generate code like

        movl    nr_cpu_ids(%rip), %edx
        addq    $63, %rdx
        shrq    $3, %rdx
        andl    $-8, %edx
        callq   memset@PLT

on x86-64, because it would calculate the "exact" number of longwords
that need to be cleared.

In contrast, with this patch, using a MAX_CPU of 64 (which is quite a
reasonable value to use), the above becomes a single

	movq $0,cpumask

instruction instead, because instead of caring to figure out exactly how
many CPU's the system has, it just knows that the cpumask will be a
single word and can just clear it all.

Note that this does end up tightening the rules a bit from the original
version in another way: operations that set bits in the cpumask are now
limited to the actual nr_cpu_ids limit, whereas we used to do the
nr_cpumask_bits thing almost everywhere in the cpumask code.

But if you just clear bits, or scan for bits, we can use the simpler
compile-time constants.

In the process, remove 'cpumask_complement()' and 'for_each_cpu_not()'
which were not useful, and which fundamentally have to be limited to
'nr_cpu_ids'.  Better remove them now than have somebody introduce use
of them later.

Of course, on x86-64 with MAXSMP there is no sane small compile-time
constant for the cpumask sizes, and we end up using the actual CPU bits,
and will generate the above kind of horrors regardless.  Please don't
use MAXSMP unless you really expect to have machines with thousands of
cores.

Linus Torvalds 1a8d05a726 VM_FAULT_RETRY fixes
Some of the page fault handlers do not deal with the following case
 correctly:
 	* handle_mm_fault() has returned VM_FAULT_RETRY
 	* there is a pending fatal signal
 	* fault had happened in kernel mode
 Correct action in such case is not "return unconditionally" - fatal
 signals are handled only upon return to userland and something like
 copy_to_user() would end up retrying the faulting instruction and
 triggering the same fault again and again.
 
 What we need to do in such case is to make the caller to treat that
 as failed uaccess attempt - handle exception if there is an exception
 handler for faulting instruction or oops if there isn't one.
 
 Over the years some architectures had been fixed and now are handling
 that case properly; some still do not.  This series should fix the
 remaining ones.
 
 Status:
 	m68k, riscv, hexagon, parisc: tested/acked by maintainers.
 	alpha, sparc32, sparc64: tested locally - bug has been
 reproduced on the unpatched kernel and verified to be fixed by
 this series.
 	ia64, microblaze, nios2, openrisc: build, but otherwise
 completely untested.

Pull VM_FAULT_RETRY fixes from Al Viro:
 "Some of the page fault handlers do not deal with the following case
  correctly:

   - handle_mm_fault() has returned VM_FAULT_RETRY

   - there is a pending fatal signal

   - fault had happened in kernel mode

  Correct action in such case is not "return unconditionally" - fatal
  signals are handled only upon return to userland and something like
  copy_to_user() would end up retrying the faulting instruction and
  triggering the same fault again and again.

  What we need to do in such case is to make the caller to treat that as
  failed uaccess attempt - handle exception if there is an exception
  handler for faulting instruction or oops if there isn't one.

  Over the years some architectures had been fixed and now are handling
  that case properly; some still do not. This series should fix the
  remaining ones.

  Status:

   - m68k, riscv, hexagon, parisc: tested/acked by maintainers.

   - alpha, sparc32, sparc64: tested locally - bug has been reproduced
     on the unpatched kernel and verified to be fixed by this series.

   - ia64, microblaze, nios2, openrisc: build, but otherwise completely
     untested"

Masahiro Yamada 95207db816 Remove Intel compiler support
include/linux/compiler-intel.h had no update in the past 3 years.

We often forget about the third C compiler to build the kernel.

For example, commit a0a12c3ed0 ("asm goto: eradicate CC_HAS_ASM_GOTO")
only mentioned GCC and Clang.

init/Kconfig defines CC_IS_GCC and CC_IS_CLANG but not CC_IS_ICC,
and nobody has reported any issue.

I guess the Intel Compiler support is broken, and nobody is caring
about it.

Harald Arnesen pointed out ICC (classic Intel C/C++ compiler) is
deprecated:

    $ icc -v
    icc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is
    deprecated and will be removed from product release in the second half
    of 2023. The Intel(R) oneAPI DPC++/C++ Compiler (ICX) is the recommended
    compiler moving forward. Please transition to use this compiler. Use
    '-diag-disable=10441' to disable this message.
    icc version 2021.7.0 (gcc version 12.1.0 compatibility)

Arnd Bergmann provided a link to the article, "Intel C/C++ compilers
complete adoption of LLVM".

lib/zstd/common/compiler.h and lib/zstd/compress/zstd_fast.c were kept
untouched for better sync with https://github.com/facebook/zstd

Linus Torvalds e77d587a2c mm: avoid gcc complaint about pointer casting
The migration code ends up temporarily stashing information of the wrong
type in unused fields of the newly allocated destination folio.  That
all works fine, but gcc does complain about the pointer type mis-use:

    mm/migrate.c: In function ‘__migrate_folio_extract’:
    mm/migrate.c:1050:20: note: randstruct: casting between randomized structure pointer types (ssa): ‘struct anon_vma’ and ‘struct address_space’

     1050 |         *anon_vmap = (void *)dst->mapping;
          |         ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~

and gcc is actually right to complain since it really doesn't understand
that this is a very temporary special case where this is ok.

This could be fixed in different ways by just obfuscating the assignment
sufficiently that gcc doesn't see what is going on, but the truly
"proper C" way to do this is by explicitly using a union.

Using unions for type conversions like this is normally hugely ugly and
syntactically nasty, but this really is one of the few cases where we
want to make it clear that we're not doing type conversion, we're really
re-using the value bit-for-bit just using another type.

IOW, this should not become a common pattern, but in this one case using
that odd union is probably the best way to document to the compiler what
is conceptually going on here.

[ Side note: there are valid cases where we convert pointers to other
  pointer types, notably the whole "folio vs page" situation, where the
  types actually have fundamental commonalities.

  The fact that the gcc note is limited to just randomized structures
  means that we don't see equivalent warnings for those cases, but it
  migth also mean that we miss other cases where we do play these kinds
  of dodgy games, and this kind of explicit conversion might be a good
  idea. ]

I verified that at least for an allmodconfig build on x86-64, this
generates the exact same code, apart from line numbers and assembler
comment changes.

Linus Torvalds e778361555 umh: simplify the capability pointer logic
The usermodehelper code uses two fake pointers for the two capability
cases: CAP_BSET for reading and writing 'usermodehelper_bset', and
CAP_PI to read and write 'usermodehelper_inheritable'.

This seems to be a completely unnecessary indirection, since we could
instead just use the pointers themselves, and never have to do any "if
this then that" kind of logic.

So just get rid of the fake pointer values, and use the real pointer
values instead.

Linus Torvalds 34c108a02c Rust fixes for 6.3-rc1
A single build error fix: there was a change during the merge window
 to a C header parsed by the Rust bindings generator, introducing a
 type that it does not handle well. The fix tells the generator to
 treat the type as opaque (for now).

Benjamin Gray a76d19e6ac i2c: Disable I2C_APPLE when I2C_PASEMI is a builtin
The ppc64le_allmodconfig sets I2C_PASEMI=y and leaves COMPILE_TEST to
default to y and I2C_APPLE to default to m, running into a known
incompatible configuration that breaks the build [1]. Specifically,
a common dependency (i2c-pasemi-core.o in this case) cannot be used by
both builtin and module consumers.

Disable I2C_APPLE when I2C_PASEMI is a builtin to prevent this.

Linus Torvalds 0bdf4a8bf0 s390 updates for 6.3 merge window part 2
- Add empty command line parameter handling stubs to kernel for all command
   line parameters which are handled in the decompressor. This avoids
   invalid "Unknown kernel command line parameters" messages from the
   kernel, and also avoids that these will be incorrectly passed to user
   space. This caused already confusion, therefore add the empty stubs
 
 - Add missing phys_to_virt() handling to machine check handler
 
 - Introduce and use a union to be used for zcrypt inline assemblies. This
   makes sure that only a register wide member of the union is passed as
   input and output parameter to inline assemblies, while usual C code uses
   other members of the union to access bit fields of it
 
 - Add and use a READ_ONCE_ALIGNED_128() macro, which can be used to
   atomically read a 128-bit value from memory. This replaces the (mis-)use
   of the 128-bit cmpxchg operation to do the same in cpum_sf code.
   Currently gcc does not generate the used lpq instruction if __READ_ONCE()
   is used for aligned 128-bit accesses, therefore use this s390 specific
   helper
 
 - Simplify machine check handler code if a task needs to be killed because
   of e.g. register corruption due to a machine malfunction
 
 - Perform CPU reset to clear pending interrupts and TLB entries on an
   already stopped target CPU before delegating work to it
 
 - Generate arch/s390/boot/vmlinux.map link map for the decompressor, when
   CONFIG_VMLINUX_MAP is enabled for debugging purposes
 
 - Fix segment type handling for dcssblk devices. It incorrectly always
   returned type "READ/WRITE" even for read-only segements, which can result
   in a kernel panic if somebody tries to write to a read-only device
 
 - Sort config S390 select list again
 
 - Fix two kprobe reenter bugs revealed by a recently added kprobe kunit

If snd_ctl_add() fails in aureon_add_controls(), it immediately returns
and leaves ice->gpio_mutex locked. ice->gpio_mutex locks in
snd_ice1712_save_gpio_status and unlocks in
snd_ice1712_restore_gpio_status(ice).

It seems that the mutex is required only for aureon_cs8415_get(),
so snd_ice1712_restore_gpio_status(ice) can be placed
just after that. Compile tested only.
