Since commit 75c2f26da0 ("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 0cd5780eb6 ("arm64:
defconfig: Fix unintentional disablement of PCI on i.MX").

As usual, this branch contains all the patches to enable options
for newly added device drivers in the 32-bit and 64-bit defconfig
files.
I have sorted the files according to the changes to Kconfig files,
to make it easier to check what has changed compared to the 'make
savedefconfig' output.
The most notable change this time is a series from Mark Brown
to add a 'virtconfig' target for arm64, which is for the moment
the same as the 'defconfig' target but disables all the top-level
SoC specific options in order to have a smaller and faster
kernel build.

ARM systems are often memory constrained and more often than not
use slow single-channel storage such as flash memory or MMC/SD-cards.
For any interactive systems (such as mobile phones, tablets,
chromebooks...) the BFQ I/O scheduler will be desireable.
Make sure the BFQ I/O scheduler is available on these systems.
Loongarch, MIPS, m68k, UM and S390 has also enabled BFQ in their
defconfigs, cf commit b495dfed70
"um: Cleanup CONFIG_IOSCHED_CFQ" where the motivation is that
it replaces the former CFQ scheduler.

For some reason that is unclear to me the i.MX defconfig for v6 and v7
boards enables PROVE_LOCKING. Since the defconfigs are generally
intended to be more production style configurations this doesn't seem
particularly intentional so drop this from the defconfig.

In order for HPE platforms to be supported by linux on GXP it is
necessary for there to be fan and spi driver support. There fan driver
can support up to 16 fans that are driven by pwm through the CPLD. The
SPI driver supports access to the core flash and bios part. The SPI
driver spi-gxp was added previously to linux.

The only missing configuration option preventing us from using
multi_v7_defconfig with the Raspberry Pi 4 is ARM_LPAE. It's needed as
the PCIe controller found on the SoC depends on 64bit addressing, yet
can't be included as not all v7 boards support LPAE.
Introduce multi_v7_lpae_defconfig, built off multi_v7_defconfig, which will
avoid us having to duplicate and maintain multiple similar configurations.
Needless to say the Raspberry Pi 4 is not the only platform that can
benefit from this new configuration.

In particular, all of the reference designs get removed now, as these

As explained in [1], we would like to remove SLOB if possible.
- There are no known users that need its somewhat lower memory footprint
so much that they cannot handle SLUB (after some modifications by the
previous patches) instead.
- It is an extra maintenance burden, and a number of features are
incompatible with it.
- It blocks the API improvement of allowing kfree() on objects allocated
via kmem_cache_alloc().
As the first step, rename the CONFIG_SLOB option in the slab allocator
configuration choice to CONFIG_SLOB_DEPRECATED. Add CONFIG_SLOB
depending on CONFIG_SLOB_DEPRECATED as an internal option to avoid code
churn. This will cause existing .config files and defconfigs with
CONFIG_SLOB=y to silently switch to the default (and recommended
replacement) SLUB, while still allowing SLOB to be configured by anyone
that notices and needs it. But those should contact the slab maintainers
and linux-mm@kvack.org as explained in the updated help. With no valid
objections, the plan is to update the existing defconfigs to SLUB and
remove SLOB in a few cycles.
To make SLUB more suitable replacement for SLOB, a CONFIG_SLUB_TINY
option was introduced to limit SLUB's memory overhead.
There is a number of defconfigs specifying CONFIG_SLOB=y. As part of
this patch, update them to select CONFIG_SLUB and CONFIG_SLUB_TINY.
