(or new bugs) will cause copies to be rejected.
This isn't a direct revert of commit 2d891fbc3b ("usercopy: Allow

effectively 0, the fallback handling is removed too.
This also removes the usercopy_fallback module parameter on slab_common.

Merge the changes to retire the legacy WR sbc8548 and sbc8641 platforms
from Paul. These were sent as a pull request, but I rebased them onto
rc2 so as not to pull too many unrelated changes in to my next.
Description from Paul's pull request follows:
In v2.6.27 (2008, 917f0af9e5) the sbc8260 support was implicitly
retired by not being carried forward through the ppc --> powerpc
device tree transition.
Then, in v3.6 (2012, b048b4e17c) we retired the support for the
sbc8560 boards.
Next, in v4.18 (2017, 3bc6cf5a86) we retired the support for the
2006 vintage sbc834x boards.
The sbc8548 and sbc8641d boards were maybe 1-2 years newer than the
sbc834x boards, but it is also 3+ years later, so it makes sense to
now retire them as well - which is what is done here.
These two remaining WR boards were based on the Freescale MPC8548-CDS
and the MPC8641D-HPCN reference board implementations. Having had the
chance to use these and many other Fsl ref boards, I know this: The
Freescale reference boards were typically produced in limited quantity
and primarily available to BSP developers and hardware designers, and
not likely to have found a 2nd life with hobbyists and/or collectors.
It was good to have that BSP code subjected to mainline review and
hence also widely available back in the day. But given the above, we
should probably also be giving serious consideration to retiring
additional similar age/type reference board platforms as well.
I've always felt it is important for us to be proactive in retiring
old code, since it has a genuine non-zero carrying cost, as described
in the 930d52c012 merge log. But for the here and now, we just
clean up the remaining BSP code that I had added for SBC platforms.
Link: https://lore.kernel.org/r/20210824174209.GB160508@windriver.com
The support was for this was added to mainline over 12 years ago, in
v2.6.26 [4e8aae89a3] just around the ppc --> powerpc migration.
I believe the board was introduced shortly after the sbc8548 board,
making it roughly a 14 year old platform - with the CPU speed and
memory size typical for that era.
I haven't had one of these boards for several years, and availability
was discontinued several years before that.
Given that, there is no point in adding a burden to testing coverage
that builds all possible defconfigs, so it makes sense to remove it.
Of course it will remain in the git history forever, for anyone who
happens to find a functional board and wants to tinker with it.

CONFIG_MTD_PHYSMAP_OF is not longer enabled as it depends on
MTD_PHYSMAP which is not enabled.
This is a regression from commit 642b1e8dbe ("mtd: maps: Merge

Add CONFIG_MTD_PHYSMAP=y so this stays in the config, as Christophe said

mpc885_ads_defconfig is used by several CI robots.
A few functionnalities are specific to 8xx and are not covered
by other default configuration, so improve build test coverage
by adding them to mpc885_ads_defconfig.
8xx is the only platform supporting 16k page size in addition
to 4k page size. Considering that 4k page size is widely tested
by other configurations, lets make 16k pages the selection for
8xx, as it has demonstrated in the past to be a weakness.
CONFIG_PIN_TLB is specific to 8xx, select it as it mainly adds
code with removing much.
CONFIG_BDI_SWITCH is specific to PPC32 and adds codes.
CONFIG_PPC_PTDUMP has specific part for 8xx.
CONFIG_MODULES has specific handling for 8xx.
CONFIG_SMC_UCODE_PATCH is specific to 8xx for loading microcode.
CONFIG_PERF_EVENTS has specific parts for 8xx.
CONFIG_MATH_EMULATION is used by 8xx.
CONFIG_STRICT_KERNEL_RWX has specificities for 8xx.
CONFIG_VIRT_CPU_ACCOUNTING_NATIVE has specific parts for PPC32.
CONFIG_IPV6 has specificities for PPC32.
CONFIG_BPF_JIT has specificities for PPC32.
A few drivers are tightly linked to the 8xx:
- CONFIG_SPI_FSL_SPI
- CONFIG_CRYPTO_DEV_TALITOS
- CONFIG_8xxx_WDT
- CONFIG_8xx_GPIO
- CONFIG_PPC_EARLY_DEBUG_CPM

Noone stepped up in the past two years since it was marked as BROKEN by

Three remarks:
* we remove also the uapi header (as noone is able to use that interface
anyway)
* we do *not* remove the N_R3964 constant definition from tty.h, so it
remains reserved.
* in_interrupt() check is now removed from vt's con_put_char. Noone else
calls tty_operations::put_char from interrupt context.

Summary of modules changes for the 5.12 merge window:
- Retire EXPORT_UNUSED_SYMBOL() and EXPORT_SYMBOL_GPL_FUTURE(). These export
types were introduced between 2006 - 2008. All the of the unused symbols have
been long removed and gpl future symbols were converted to gpl quite a long
time ago, and I don't believe these export types have been used ever since.
So, I think it should be safe to retire those export types now. (Christoph Hellwig)

- Retire EXPORT_UNUSED_SYMBOL() and EXPORT_SYMBOL_GPL_FUTURE(). These
export types were introduced between 2006 - 2008. All the of the
unused symbols have been long removed and gpl future symbols were
converted to gpl quite a long time ago, and I don't believe these
export types have been used ever since. So, I think it should be safe
to retire those export types now (Christoph Hellwig)
- Refactor and clean up some aged code cruft in the module loader
(Christoph Hellwig)
- Build {,module_}kallsyms_on_each_symbol only when livepatching is
enabled, as it is the only caller (Christoph Hellwig)
- Unexport find_module() and module_mutex and fix the last module
callers to not rely on these anymore. Make module_mutex internal to
the module loader (Christoph Hellwig)
- Harden ELF checks on module load and validate ELF structures before
checking the module signature (Frank van der Linden)
- Fix undefined symbol warning for clang (Fangrui Song)
- Fix smatch warning (Dan Carpenter)

A large series adding wrappers for our interrupt handlers, so that irq/nmi/user
tracking can be isolated in the wrappers rather than spread in each handler.
Conversion of the 32-bit syscall handling into C.
A series from Nick to streamline our TLB flushing when using the Radix MMU.
Switch to using queued spinlocks by default for 64-bit server CPUs.
A rework of our PCI probing so that it happens later in boot, when more generic
infrastructure is available.
Two small fixes to allow 32-bit little-endian processes to run on 64-bit
kernels.
Other smaller features, fixes & cleanups.

The AKEBONO config has various selects under it, including some with
user-selectable dependencies, which means those dependencies can be
disabled. This leads to warnings from Kconfig.
This can be seen with eg:
$ make allnoconfig
$ ./scripts/config --file build~/.config -k -e CONFIG_44x -k -e CONFIG_PPC_47x -e CONFIG_AKEBONO
$ make olddefconfig
WARNING: unmet direct dependencies detected for ATA

Depends on [n]: MMC [=n] && MMC_SDHCI [=y]
Selected by [y]:
- AKEBONO [=y] && PPC_47x [=y]
The problem is that AKEBONO is using select to enable things that are
not true dependencies, but rather things you probably want enabled in
an AKEBONO kernel. That is what a defconfig is for.
So drop those selects and instead move those symbols into the
defconfig. This fixes all the kconfig warnings, and the result of make
44x/akebono_defconfig is the same before and after the patch.

The "oprofile" user-space tools don't use the kernel OPROFILE support
any more, and haven't in a long time. User-space has been converted to
the perf interfaces.
This commits stops building oprofile for powerpc and removes any
reference to it from directories in arch/powerpc/ apart from
arch/powerpc/oprofile, which will be removed in the next commit (this is
broken into two commits as the size of the commit became very big, ~5k
lines).
Note that the member "oprofile_cpu_type" in "struct cpu_spec" isn't
removed as it was also used by other parts of the code.

The driver has its own HID descriptor parsing code, that had and still
has several issues discovered by syzbot and other tools. Ideally we
should move the driver over to the HID subsystem, so that it uses proven
parsing code. However the devices in question are EOL, and GTCO is not
willing to extend resources for that, so let's simply remove the driver.
Note that our HID support has greatly improved over the last 10 years,
we may also consider reverting 6f8d9e26e7 ("hid-core.c: Adds all GTCO
CalComp Digitizers and InterWrite School Products to blacklist") and see
if GTCO devices actually work with normal HID drivers.

It's sometimes handy to have a config that boots a bit like a system
under secure boot (forcing lockdown=integrity, without needing any
extra stuff like a command line option).
This config file allows that, and also turns on a few assorted security
and hardening options for good measure.

A note from the vendor:
"The hardware used with synclink.c and synclinkmp.c has not been
manufactured for 15 years and was low volume. The chances of either
driver still being in use is very low. Not even Microgate (me) has
the ability to test either anymore (no hardware). I don’t know the
policy about driver removal, but I think both could be removed
without upsetting anyone."

Drop the separate Kconfig symbol for Xircom / Entrega and always include
support in the keyspan_pda driver.
Note that all configs that enabled CONFIG_USB_SERIAL_XIRCOM also enable
CONFIG_USB_SERIAL_KEYSPAN_PDA.

Yunhai Zhang recently fixed a VGA software scrollback bug in commit
ebfdfeeae8 ("vgacon: Fix for missing check in scrollback handling"),
but that then made people look more closely at some of this code, and
there were more problems on the vgacon side, but also the fbcon software
scrollback.
We don't really have anybody who maintains this code - probably because
nobody actually _uses_ it any more. Sure, people still use both VGA and
the framebuffer consoles, but they are no longer the main user
interfaces to the kernel, and haven't been for decades, so these kinds
of extra features end up bitrotting and not really being used.
So rather than try to maintain a likely unused set of code, I'll just
aggressively remove it, and see if anybody even notices. Maybe there
are people who haven't jumped on the whole GUI badnwagon yet, and think
it's just a fad. And maybe those people use the scrollback code.
If that turns out to be the case, we can resurrect this again, once
we've found the sucker^Wmaintainer for it who actually uses it.
