Commit ddb5cdbafaaad ("kbuild: generate KSYMTAB entries by modpost")
deprecated <asm/export.h>, which is now a wrapper of <linux/export.h>.
Replace #include <asm/export.h> with #include <linux/export.h>.
After all the <asm/export.h> lines are converted, <asm/export.h> and
<asm-generic/export.h> will be removed.

As explained by Nick in the original issue: the kernel usually does a
good job of providing library helpers that have similar semantics as
their ordinary userspace libc equivalents, but -ffreestanding disables
such libcall optimization and other related features in the compiler,
which can lead to unexpected things such as CONFIG_FORTIFY_SOURCE not
working (!).
However, due to the desire for better control over unaligned accesses
with respect to CONFIG_ARCH_STRICT_ALIGN, and also for avoiding the
GCC bug https://gcc.gnu.org/PR109465, we do want to still disable
optimizations for the memory libcalls (memcpy, memmove and memset for
now). Use finer-grained -fno-builtin-* toggles to achieve this without
losing source fortification and other libcall optimizations.

In drivers/Kconfig, drivers/firmware/Kconfig is sourced for all ports so
there is no need to source it in the port-specific Kconfig file. And
sourcing it here also caused the "Firmware Drivers" menu appeared two
times: one in the "Device Drivers" menu, another in the toplevel menu.
This is really puzzling so remove it.

All posix lock ops, for all lockspaces (gfs2 file systems) are
sent to userspace (dlm_controld) through a single misc device.
The dlm_controld daemon reads the ops from the misc device
and sends them to other cluster nodes using separate, per-lockspace
cluster api communication channels. The ops for a single lockspace
are ordered at this level, so that the results are received in
the same sequence that the requests were sent. When the results
are sent back to the kernel via the misc device, they are again
funneled through the single misc device for all lockspaces. When
the dlm code in the kernel processes the results from the misc
device, these results will be returned in the same sequence that
the requests were sent, on a per-lockspace basis. A recent change
in this request/reply matching code missed the "per-lockspace"
check (fsid comparison) when matching request and reply, so replies
could be incorrectly matched to requests from other lockspaces.

A trivial execve scalability test which tries to be very friendly
(statically linked binaries, all separate) is predominantly bottlenecked
by back-to-back per-cpu counter allocations which serialize on global
locks.
Ease the pain by allocating and freeing them in one go.
Bench can be found here:
http://apollo.backplane.com/DFlyMisc/doexec.c
$ cc -static -O2 -o static-doexec doexec.c
$ ./static-doexec $(nproc)
Even at a very modest scale of 26 cores (ops/s):
before: 133543.63
after: 186061.81 (+39%)
While with the patch these allocations remain a significant problem,
the primary bottleneck shifts to page release handling.

Allocations and frees are globally serialized on the pcpu lock (and the
CPU hotplug lock if enabled, which is the case on Debian).
At least one frequent consumer allocates 4 back-to-back counters (and
frees them in the same manner), exacerbating the problem.
While this does not fully remedy scalability issues, it is a step
towards that goal and provides immediate relief.

fail_iommu_setup() registers the fail_iommu_bus_notifier struct to both
PCI and VIO buses. struct notifier_block is a linked list node, so this
causes any notifiers later registered to either bus type to also be
registered to the other since they share the same node.
This causes issues in (at least) the vgaarb code, which registers a
notifier for PCI buses. pci_notify() ends up being called on a vio
device, converted with to_pci_dev() even though it's not a PCI device,
and finally makes a bad access in vga_arbiter_add_pci_device() as
discovered with KASAN:

Remove support for gpio_disable_free() because it is called when the libgpiod
command "gpioset" is invoked. This gives the GPIO control back to hardware which
cancels out the effort to set the GPIO value.
Reminder of the code flow to change a GPIO value from software:
1) All GPIOs are controlled by hardware by default
2) To change the GPIO value, enable software control via a mux.
3) Once software has control over the GPIO pin, the gpio-mlxbf3 driver
will be able to change the direction and value of the GPIO.
When the user runs "gpioset gpiochip0 0=0" for example, the gpio
pin value should change from 1 to 0. In this case, mlxbf3_gpio_request_enable()
is called via gpiochip_generic_request(). The latter switches GPIO control from
hardware to software. Then the GPIO value is changed from 1 to 0. However,
gpio_disable_free() is also called which changes control back to hardware
which changes the GPIO value back to 1.

enc_dec_hypercall() accepted a page count instead of a size, which
forced its callers to round up. As a result, non-page aligned
vaddrs caused pages to be spuriously marked as decrypted via the
encryption status hypercall, which in turn caused consistent
corruption of pages during live migration. Live migration requires
accurate encryption status information to avoid migrating pages
from the wrong perspective.
Fixes: 064ce6c550a0 ("mm: x86: Invoke hypercall when page encryption status is changed")

This reverts commit b9296bb41275 ("dt-bindings: crypto: qcom,prng: Add SM8450"),
since the RNG HW on the SM8450 SoC is in fact a True Random Number Generator,
a more appropriate compatible should be instead as reported at [1].
