We need the tty/serial fixes in here and this resolves a merge issue in
the 8250 driver.

Pull tty/serial/fbcon fixes from Greg KH:
"Here are some small tty/serial and one more fbcon fix.
They include:
- serial core locking regression fixes
- new device ids for 8250_pci driver
- fbcon fix for syzbot found issue
All have been in linux-next with no reported issues"
* tag 'tty-5.9-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty:
fbcon: Fix user font detection test at fbcon_resize().
serial: 8250_pci: Add Realtek 816a and 816b
serial: core: fix console port-lock regression
serial: core: fix port-lock initialisation
This (and the VGA soft scrollback) turns out to have various nasty small
special cases that nobody really is willing to fight. The soft
scrollback code was really useful a few decades ago when you typically
used the console interactively as the main way to interact with the
machine, but that just isn't the case any more.
So it's not worth dragging along.

Samsung S3C24xx and S3C64xx machine code cleanup for v5.10
Big cleanup for the Samsung S3C24xx and S3C64xx platforms, although it
also touches files shared with S5Pv210 and Exynos. This is mostly Arnd
Bergmann work which Krzysztof Kozlowski took over, rebased and polished.
The goal is to cleanup, merge and finally make the Samsung S3C24xx and
S3C64xx architectures multiplatform. The multiplatform did not happen
yet here - just cleaning up and merging into one arch/arm/mach-s3c
directory. However this is step forward for multiplatform or at least
to keep this code still maintainable.
This pulls also branch with changes for Samsung SoC sound drivers from
broonie/sound because the cleanups there were part of this series and
all further patches depend on them.

Drivers should do only device-specific jobs. But in general, drivers using
legacy PCI PM framework for .suspend()/.resume() have to manage many PCI
PM-related tasks themselves which can be done by PCI Core itself. This
brings extra load on the driver and it directly calls PCI helper functions
to handle them.
Switch to the new generic framework by updating function signatures and
define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove
unnecessary calls to the PCI Helper functions along with the legacy
.suspend & .resume bindings.
The ark_pci_suspend() is not designed to function in the case of Freeze.
Thus, the code checked for "if (state.event == PM_EVENT_FREEZE....)". This
is because, in the legacy framework, this callback was invoked even in the
event of Freeze. Hence, added the load of unnecessary function-call.
The goal can be achieved by binding the callback with only ".suspend" and
".poweroff" in the "ark_pci_pm_ops" const variable. This also avoids the
step of checking "state.event == PM_EVENT_FREEZE" every time the callback
is invoked.

Pull powerpc fixes from Michael Ellerman:
- Revert our removal of PROT_SAO, at least one user expressed an
interest in using it on Power9. Instead don't allow it to be used in
guests unless enabled explicitly at compile time.
- A fix for a crash introduced by a recent change to FP handling.
- Revert a change to our idle code that left Power10 with no idle
support.
- One minor fix for the new scv system call path to set PPR.
- Fix a crash in our "generic" PMU if branch stack events were enabled.
- A fix for the IMC PMU, to correctly identify host kernel samples.
- The ADB_PMU powermac code was found to be incompatible with
VMAP_STACK, so make them incompatible in Kconfig until the code can
be fixed.
- A build fix in drivers/video/fbdev/controlfb.c, and a documentation
fix.

The build is currently broken, if COMPILE_TEST=y and PPC_PMAC=n:
linux/drivers/video/fbdev/controlfb.c: In function ‘control_set_hardware’:
linux/drivers/video/fbdev/controlfb.c:276:2: error: implicit declaration of function ‘btext_update_display’
276 | btext_update_display(p->frame_buffer_phys + CTRLFB_OFF,

Fix it by including btext.h whenever CONFIG_BOOTX_TEXT is enabled.
