026246f114 arch/*/io.h: remove ioremap_uc in some architectures 
ioremap_uc() is only meaningful on old x86-32 systems with the PAT
extension, and on ia64 with its slightly unconventional ioremap()
behavior. So remove the ioremap_uc() definition in architecutures
other than x86 and ia64. These architectures all have asm-generic/io.h
included and will have the default ioremap_uc() definition which
returns NULL.

This changes the existing behaviour, while no need to worry about
any breakage because in the only callsite of ioremap_uc(), code
has been adjusted to eliminate the impact. Please see
atyfb_setup_generic() of drivers/video/fbdev/aty/atyfb_base.c.

If any new invocation of ioremap_uc() need be added, please consider
using ioremap() intead or adding a ARCH specific version if necessary.

abc28463c8 kprobes: unify kprobes_exceptions_nofify() prototypes 
Most architectures that support kprobes declare this function in their
own asm/kprobes.h header and provide an override, but some are missing
the prototype, which causes a warning for the __weak stub implementation:

kernel/kprobes.c:1865:12: error: no previous prototype for 'kprobe_exceptions_notify' [-Werror=missing-prototypes]
 1865 | int __weak kprobe_exceptions_notify(struct notifier_block *self,

Move the prototype into linux/kprobes.h so it is visible to all
the definitions.

8f6f76a6a2 As usual, lots of singleton and doubleton patches all over the tree and 
there's little I can say which isn't in the individual changelogs.
 
 The lengthier patch series are
 
 - "kdump: use generic functions to simplify crashkernel reservation in
   arch", from Baoquan He.  This is mainly cleanups and consolidation of
   the "crashkernel=" kernel parameter handling.
 
 - After much discussion, David Laight's "minmax: Relax type checks in
   min() and max()" is here.  Hopefully reduces some typecasting and the
   use of min_t() and max_t().
 
 - A group of patches from Oleg Nesterov which clean up and slightly fix
   our handling of reads from /proc/PID/task/...  and which remove
   task_struct.therad_group.

Merge tag 'sh-for-v6.7-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux

Pull sh updates from John Paul Adrian Glaubitz:
 "While the previously announced patch series for converting arch/sh to
  device trees is not yet ready for inclusion to mainline and therefore
  didn't make it for this pull request, there are still a small number
  changes for v6.7 which include one platform (board plus CPU and driver
  code) removal plus two fixes.

  The removal sent in by Arnd Bergmann concerns the microdev board which
  was an early SuperH prototype board that was never used in production.
  With the board removed, we were able to drop the now unused code for
  the SH4-202 CPU and well as the driver code for the superhyway bus and
  a custom implementation for ioport_map() and ioport_unmap() which will
  allow us to simplify ioport handling in the future.

  Another patch set by Geert Uytterhoeven revives SuperH BIOS
  earlyprintk support which got accidentally disabled in
  e76fe57447 ("sh: Remove old early serial console code V2"), the
  second patch in the series updates the documentation.

  Finally, a patch by Masami Hiramatsu fixes a regression reported by
  the kernel test robot which uncovered that arch/sh is not implementing
  arch_cmpxchg_local() and therefore needs use __generic_cmpxchg_local()
  instead"

edd8e84ae9 sound updates for 6.7 
Most of changes at this time are for ASoC, spread over ASoC core and
 drivers due to the API prefix standardization.  Other than that, there
 have little change wrt API, rather lots of driver-specific updates and
 fixes.  Some highlight below:
 
 ASoC:
 - Standardization of API prefix
 - GPIO API usage improvements
 - Support for HDA patches
 - Lots of work on SOF, including crash dump support
 - Fixes for noise when stopping some Sounwire CODECs
 - Support for AMD platforms with es83xx, AMD ACP 6.3 and 7.0, Awinc
   AT87390 and AW88399, many Intel platforms, many Mediatek platforms,
   Qualcomm SM6115 and SC7180 platforms, Richtek RTQ9128 and Texas
   Instruments TAS575x
 
 HD-audio and USB-audio:
 - Deferred probe support of audio component binding
 - More fixes and enhancements for Cirrus subcodecs
 - USB Scarlett2 mixer and McIntosh DSD quirk
 
 Others:
 - More enhancement of snd-aloop driver
 - Update MAINTAINERS entry for linux-sound mailing list

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Use acpi_evaluate_dsm_typed() instead of open-coding _DSM
     evaluation to learn device characteristics (Andy Shevchenko)

   - Tidy multi-function header checks using new PCI_HEADER_TYPE_MASK
     definition (Ilpo Järvinen)

   - Simplify config access error checking in various drivers (Ilpo
     Järvinen)

   - Use pcie_capability_clear_word() (not
     pcie_capability_clear_and_set_word()) when only clearing (Ilpo
     Järvinen)

   - Add pci_get_base_class() to simplify finding devices using base
     class only (ignoring subclass and programming interface) (Sui
     Jingfeng)

   - Add pci_is_vga(), which includes ancient PCI_CLASS_NOT_DEFINED_VGA
     devices from before the Class Code was added to PCI (Sui Jingfeng)

   - Use pci_is_vga() for vgaarb, sysfs "boot_vga", virtio, qxl to
     include ancient VGA devices (Sui Jingfeng)

  Resource management:

   - Make pci_assign_unassigned_resources() non-init because sparc uses
     it after init (Randy Dunlap)

  Driver binding:

   - Retain .remove() and .probe() callbacks (previously __init) because
     sysfs may cause them to be called later (Uwe Kleine-König)

   - Prevent xHCI driver from claiming AMD VanGogh USB3 DRD device, so
     it can be claimed by dwc3 instead (Vicki Pfau)

  PCI device hotplug:

   - Add Ampere Altra Attention Indicator extension driver for acpiphp
     (D Scott Phillips)

  Power management:

   - Quirk VideoPropulsion Torrent QN16e with longer delay after reset
     (Lukas Wunner)

   - Prevent users from overriding drivers that say we shouldn't use
     D3cold (Lukas Wunner)

   - Avoid PME from D3hot/D3cold for AMD Rembrandt and Phoenix USB4
     because wakeup interrupts from those states don't work if amd-pmc
     has put the platform in a hardware sleep state (Mario Limonciello)

  IOMMU:

   - Disable ATS for Intel IPU E2000 devices with invalidation message
     endianness erratum (Bartosz Pawlowski)

  Error handling:

   - Factor out interrupt enable/disable into helpers (Kai-Heng Feng)

  Peer-to-peer DMA:

   - Fix flexible-array usage in struct pci_p2pdma_pagemap in case we
     ever use pagemaps with multiple entries (Gustavo A. R. Silva)

  ASPM:

   - Revert a change that broke when drivers disabled L1 and users later
     enabled an L1.x substate via sysfs, and fix a similar issue when
     users disabled L1 via sysfs (Heiner Kallweit)

  Endpoint framework:

   - Fix double free in __pci_epc_create() (Dan Carpenter)

   - Use IS_ERR_OR_NULL() to simplify endpoint core (Ruan Jinjie)

  Cadence PCIe controller driver:

   - Drop unused "is_rc" member (Li Chen)

  Freescale Layerscape PCIe controller driver:

   - Enable 64-bit addressing in endpoint mode (Guanhua Gao)

  Intel VMD host bridge driver:

   - Fix multi-function header check (Ilpo Järvinen)

  Microsoft Hyper-V host bridge driver:

   - Annotate struct hv_dr_state with __counted_by (Kees Cook)

  NVIDIA Tegra194 PCIe controller driver:

   - Drop setting of LNKCAP_MLW (max link width) since dw_pcie_setup()
     already does this via dw_pcie_link_set_max_link_width() (Yoshihiro
     Shimoda)

  Qualcomm PCIe controller driver:

   - Use PCIE_SPEED2MBS_ENC() to simplify encoding of link speed
     (Manivannan Sadhasivam)

   - Add a .write_dbi2() callback so DBI2 register writes, e.g., for
     setting the BAR size, work correctly (Manivannan Sadhasivam)

   - Enable ASPM for platforms that use 1.9.0 ops, because the PCI core

553f7ac78f sh: bios: Revive earlyprintk support 
The SuperH BIOS earlyprintk code is protected by CONFIG_EARLY_PRINTK.
However, when this protection was added, it was missed that SuperH no
longer defines an EARLY_PRINTK config symbol since commit
e76fe57447 ("sh: Remove old early serial console code V2"), so
BIOS earlyprintk can no longer be used.

Fix this by reviving the EARLY_PRINTK config symbol.

3ca64d0669 sh: Remove stale microdev board 
This board was an early prototype platform for early SH4 CPUs and related
to the already removed SH5 cayman platform.

The microdev board itself has been kept in the tree for this long despite
being in a bad shape even 20 years ago when it got merged, with no working
PCI support and ugly workarounds for its I/O port implementation that
try to emulate PC style peripheral access despite being quite different
in reality.

As far as I can tell, the ethernet, display, USB and PCI devices on it
already broke at some point (afbb9d8d52, 46bc858720), so I think
we can just removeit entirely.

they copied it from another architecture in order to build the VGA console

2fd0ebad27 arch: Reserve map_shadow_stack() syscall number for all architectures 
commit c35559f94e ("x86/shstk: Introduce map_shadow_stack syscall")
recently added support for map_shadow_stack() but it is limited to x86
only for now. There is a possibility that other architectures (namely,
arm64 and RISC-V), that are implementing equivalent support for shadow
stacks, might need to add support for it.

Independent of that, reserving arch-specific syscall numbers in the
syscall tables of all architectures is good practice and would help
avoid future conflicts. map_shadow_stack() is marked as a conditional
syscall in sys_ni.c. Adding it to the syscall tables of other
architectures is harmless and would return ENOSYS when exercised.

Note, map_shadow_stack() was assigned #453 during the merge process
since #452 was taken by fchmodat2().

For Powerpc, map it to sys_ni_syscall() as is the norm for Powerpc
syscall tables.

For Alpha, map_shadow_stack() takes up #563 as Alpha still diverges from
the common syscall numbering system in the other architectures.

0f4b5f9722 futex: Add sys_futex_requeue() 
Finish off the 'simple' futex2 syscall group by adding
sys_futex_requeue(). Unlike sys_futex_{wait,wake}() its arguments are
too numerous to fit into a regular syscall. As such, use struct
futex_waitv to pass the 'source' and 'destination' futexes to the
syscall.

This syscall implements what was previously known as FUTEX_CMP_REQUEUE
and uses {val, uaddr, flags} for source and {uaddr, flags} for
destination.

This design explicitly allows requeueing between different types of
futex by having a different flags word per uaddr.

ioremap_prot() calls ioremap_fixed() (which is marked __init), but only

Pull sh updates from Adrian Glaubitz:

 - Fix a use-after-free bug in the push-switch driver (Duoming Zhou)

 - Fix calls to dma_declare_coherent_memory() that incorrectly passed
   the buffer end address instead of the buffer size as the size
   parameter

246f80a0b1 sh: push-switch: Reorder cleanup operations to avoid use-after-free bug 
The original code puts flush_work() before timer_shutdown_sync()
in switch_drv_remove(). Although we use flush_work() to stop
the worker, it could be rescheduled in switch_timer(). As a result,
a use-after-free bug can occur. The details are shown below:

      (cpu 0)                    |      (cpu 1)
switch_drv_remove()              |
 flush_work()                    |
  ...                            |  switch_timer // timer
                                 |   schedule_work(&psw->work)
 timer_shutdown_sync()           |
 ...                             |  switch_work_handler // worker
 kfree(psw) // free              |
                                 |   psw->state = 0 // use

This patch puts timer_shutdown_sync() before flush_work() to
mitigate the bugs. As a result, the worker and timer will be
stopped safely before the deallocate operations.

Merge tag 'x86_shstk_for_6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 shadow stack support from Dave Hansen:
 "This is the long awaited x86 shadow stack support, part of Intel's
  Control-flow Enforcement Technology (CET).

  CET consists of two related security features: shadow stacks and
  indirect branch tracking. This series implements just the shadow stack
  part of this feature, and just for userspace.

  The main use case for shadow stack is providing protection against
  return oriented programming attacks. It works by maintaining a
  secondary (shadow) stack using a special memory type that has
  protections against modification. When executing a CALL instruction,
  the processor pushes the return address to both the normal stack and
  to the special permission shadow stack. Upon RET, the processor pops
  the shadow stack copy and compares it to the normal stack copy.

  For more information, refer to the links below for the earlier
  versions of this patch set"

Merge tag 'v6.6-vfs.fchmodat2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull fchmodat2 system call from Christian Brauner:
 "This adds the fchmodat2() system call. It is a revised version of the
  fchmodat() system call, adding a missing flag argument. Support for
  both AT_SYMLINK_NOFOLLOW and AT_EMPTY_PATH are included.

  Adding this system call revision has been a longstanding request but
  so far has always fallen through the cracks. While the kernel
  implementation of fchmodat() does not have a flag argument the libc
  provided POSIX-compliant fchmodat(3) version does. Both glibc and musl
  have to implement a workaround in order to support AT_SYMLINK_NOFOLLOW
  (see [1] and [2]).

  The workaround is brittle because it relies not just on O_PATH and
  O_NOFOLLOW semantics and procfs magic links but also on our rather
  inconsistent symlink semantics.

  This gives userspace a proper fchmodat2() system call that libcs can
  use to properly implement fchmodat(3) and allows them to get rid of
  their hacks. In this case it will immediately benefit them as the
  current workaround is already defunct because of aformentioned
  inconsistencies.

  In addition to AT_SYMLINK_NOFOLLOW, give userspace the ability to use
  AT_EMPTY_PATH with fchmodat2(). This is already possible with
  fchownat() so there's no reason to not also support it for
  fchmodat2().

  The implementation is simple and comes with selftests. Implementation
  of the system call and wiring up the system call are done as separate
  patches even though they could arguably be one patch. But in case
  there are merge conflicts from other system call additions it can be
  beneficial to have separate patches"

0453c9a780 sh: mm: convert to GENERIC_IOREMAP 
By taking GENERIC_IOREMAP method, the generic generic_ioremap_prot(),
generic_iounmap(), and their generic wrapper ioremap_prot(), ioremap() and
iounmap() are all visible and available to arch.  Arch needs to provide
wrapper functions to override the generic versions if there's arch
specific handling in its ioremap_prot(), ioremap() or iounmap().  This
change will simplify implementation by removing duplicated code with
generic_ioremap_prot() and generic_iounmap(), and has the equivalent
functioality as before.

Here, add wrapper functions ioremap_prot() and iounmap() for SuperH's
special operation when ioremap() and iounmap().

b94692e84d sh: add <asm-generic/io.h> including 
In <asm-generic/io.h>, it provides a generic implementation of all
I/O accessors.

For some port|mm io functions, SuperH has its own implementation in
arch/sh/kernel/iomap.c and arch/sh/include/asm/io_noioport.h.  These will
conflict with those in <asm-generic/io.h> and cause compiling error. 
Hence add macro definitions to ensure that the SuperH version of them will
override the generic version.

1f2190d6b7 arch/*/configs/*defconfig: Replace AUTOFS4_FS by AUTOFS_FS 
Commit a2225d931f ("autofs: remove left-over autofs4 stubs")
promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS
within a couple of releases, but five years later this still has not
happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs.

Get rid of it mechanically:

   git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' |
       xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/'

Also just remove the AUTOFS4_FS config option stub.  Anybody who hasn't
regenerated their config file in the last five years will need to just
get the new name right when they do.
