The ir-rx51 is a pwm-based TX driver specific to the N900. This can be
handled entirely by the generic pwm-ir-tx driver, and in fact the
pwm-ir-tx driver has been compatible with ir-rx51 from the start.
Note that the suspend code in the ir-rx51 driver is unnecessary, since
during transmit, the process is not in interruptable sleep. The process
is not put to sleep until the transmit completes.

Thierry says this is not used anymore, and doesn't think it makes sense as
an iommu driver. The HW it supports is about 10 years old now and newer HW
uses different IOMMU drivers.
As this is the only driver with a GART approach, and it doesn't really
meet the driver expectations from the IOMMU core, let's just remove it
so we don't have to think about how to make it fit in.
It has a number of identified problems:
- The assignment of iommu_groups doesn't match the HW behavior
- It claims to have an UNMANAGED domain but it is really an IDENTITY
domain with a translation aperture. This is inconsistent with the core
expectation for security sensitive operations
- It doesn't implement a SW page table under struct iommu_domain so
* It can't accept a map until the domain is attached
* It forgets about all maps after the domain is detached
* It doesn't clear the HW of maps once the domain is detached
(made worse by having the wrong groups)

Inspired by Salvatore Mesoraca's earlier[1] efforts to provide some
in-tree guidance for kernel hardening Kconfig options, add a new fragment
named "hardening-basic.config" (along with some arch-specific fragments)
that enable a basic set of kernel hardening options that have the least
(or no) performance impact and remove a reasonable set of legacy APIs.
Using this fragment is as simple as running "make hardening.config".
More extreme fragments can be added[2] in the future to cover all the
recognized hardening options, and more per-architecture files can be
added too.
For now, document the fragments directly via comments. Perhaps .rst
documentation can be generated from them in the future (rather than the
other way around).

Commit a2225d931f75 ("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.

Merge tag 'slab-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
- SLAB deprecation:
Following the discussion at LSF/MM 2023 [1] and no objections, the
SLAB allocator is deprecated by renaming the config option (to make
its users notice) to CONFIG_SLAB_DEPRECATED with updated help text.
SLUB should be used instead. Existing defconfigs with CONFIG_SLAB are
also updated.
- SLAB_NO_MERGE kmem_cache flag (Jesper Dangaard Brouer):
There are (very limited) cases where kmem_cache merging is
undesirable, and existing ways to prevent it are hacky. Introduce a
new flag to do that cleanly and convert the existing hacky users.
Btrfs plans to use this for debug kernel builds (that use case is
always fine), networking for performance reasons (that should be very
rare).
- Replace the usage of weak PRNGs (David Keisar Schmidt):
In addition to using stronger RNGs for the security related features,
the code is a bit cleaner.
- Misc code cleanups (SeongJae Parki, Xiongwei Song, Zhen Lei, and
zhaoxinchao)

As discussed at LSF/MM [1] [2] and with no objections raised there,
deprecate the SLAB allocator. Rename the user-visible option so that
users with CONFIG_SLAB=y get a new prompt with explanation during make
oldconfig, while make olddefconfig will just switch to SLUB.
In all defconfigs with CONFIG_SLAB=y remove the line so those also
switch to SLUB. Regressions due to the switch should be reported to
linux-mm and slab maintainers.

Testing on a imx6dl board with a QCA9377 SDIO Wifi chip shows that the
QCA9377 firmware takes more than three minutes to start getting loaded,
which is a very inconvenient behavior.
CONFIG_FW_LOADER_USER_HELPER and CONFIG_FW_LOADER_USER_HELPER_FALLBACK
were selected by commit 30fdd51be161 ("ARM: imx_v6_v7_defconfig:
add CONFIG_FW_LOADER_USER_HELPER")
By removing the CONFIG_FW_LOADER_USER_HELPER and
CONFIG_FW_LOADER_USER_HELPER_FALLBACK options the QCA9377 firmware is
loaded around 10 seconds after boot, which is the expected behavior.
The motivation for commit 30fdd51be161 ("ARM: imx_v6_v7_defconfig:
add CONFIG_FW_LOADER_USER_HELPER") was related to loading the SDMA
firmware,and at the time of that commit, the SDMA driver was loaded
as built-in.
Now that the SDMA driver is selected as a kernel module, its firmware can
be successfully loaded as well without the need of
CONFIG_FW_LOADER_USER_HELPER and CONFIG_FW_LOADER_USER_HELPER_FALLBACK.
Remove the selection of these two options.
Also, successfully tested the loading of the VPU firmware without
these options.

Most of the changes just enable additional device drivers that
were added or that are often used on major platforms.
The virtconfig added last time now disables additional drivers
to shrink kernels for virtual machines.
The obsolete oxnas_v6_defconfig file is removed in turn.

The Versatile Express should conform to standard contemporary

the AFS flash partitions as these are used on the platform.
The removed SCHED_DEBUG is due to Kconfig changes.

Update the U8500 defconfig accordingly:
- Add the NFC modules used by some U8500-based systems.
- Switch out the now deleted UX500 crypto drivers to the
STM32 drivers that we have augmented to work with
UX500.

Build CONFIG_IMX_SDMA as a module to allow the SDMA firmware be
retrieved after the rootfs is mounted.
This change aligns with the one already done for imx_v6_v7_defconfig
in commit 5a7374ec715d ("ARM: imx_v6_v7_defconfig: build imx sdma driver
as module").

Since commit 75c2f26da03f ("PCI: imx6: Add i.MX PCIe EP mode support")
the i.MX6 PCI driver is no longer selected by default. The
existing PCI_IMX6 was made a hidden option, selected by new options
PCI_IMX6_HOST (for the existing support) and PCI_IMX6_EP (for the
endpoint mode), but there has been no corresponding update to
imx_v6_v7_defconfig so the PCI_IMX6 ends up getting disabled.
Switch imx_v6_v7_defconfig to PCI_IMX6_HOST to preserve the existing
functionality.
This is based on the same fix done in commit 0cd5780eb625 ("arm64:
defconfig: Fix unintentional disablement of PCI on i.MX").
Fixes: 75c2f26da03f ("PCI: imx6: Add i.MX PCIe EP mode support")
