If the ROM provides functional STI routines, always register the sticon
driver, even if the serial console was choosen as boot device.
Additionally, in that case, do not make the sticon driver the default
output console device.

On gen2 HyperV VM, hyperv_fb will remove the old framebuffer, and the
new allocated framebuffer address could be at a differnt location,
and it might be no longer a VGA framebuffer.
Update screen_info so that after kexec the kernel won't try to reuse
the old invalid/stale framebuffer address as VGA, corrupting memory.

Also partially revert the follow-up change "drm: pl111: Absorb the
external register header".
This reverts the parts of commits
7e4e589db76a3cf4c1f534eb5a09cc6422766b93 and
0fb8125635e8eb5483fb095f98dcf0651206a7b8 that touch paths outside
of drivers/gpu/drm/pl111.
The fbdev driver is used by Android's FVP configuration. Using the
DRM driver together with DRM's fbdev emulation results in a failure
to boot Android. The root cause is that Android's generic fbdev
userspace driver relies on the ability to set the pixel format via
FBIOPUT_VSCREENINFO, which is not supported by fbdev emulation.
There have been other less critical behavioral differences identified
between the fbdev driver and the DRM driver with fbdev emulation. The
DRM driver exposes different values for the panel's width, height and
refresh rate, and the DRM driver fails a FBIOPUT_VSCREENINFO syscall
with yres_virtual greater than the maximum supported value instead
of letting the syscall succeed and setting yres_virtual based on yres.

This is one of the last users of compat_alloc_user_space()
and copy_in_user(). The actual handler is implemented in the
same file and could be shared, but as I couldn't test this
properly I leave the native case alone and just make a straight

No driver implements FBIOSCURSOR, so this function has no purpose
and can be removed. Apparently it was added in linux-2.1.44 to handle
compatibility for drivers/sbus/char/sunfb.c but lost its purpose when
that driver got rewritten in linux-2.5.63.

fbcon_get_font() is reading out-of-bounds. A malicious user may resize
`vc->vc_font.height` to a large value, causing fbcon_get_font() to
read out of `fontdata`.
fbcon_get_font() handles both built-in and user-provided fonts.
Fortunately, recently we have added FONT_EXTRA_WORDS support for built-in
fonts, so fix it by adding range checks using FNTSIZE().
This patch depends on patch "fbdev, newport_con: Move FONT_EXTRA_WORDS
macros into linux/font.h", and patch "Fonts: Support FONT_EXTRA_WORDS
macros for built-in fonts".

syzbot is reporting OOB read at fbcon_resize() [1], for
commit 39b3cffb8cf31117 ("fbcon: prevent user font height or width change
from causing potential out-of-bounds access") is by error using
registered_fb[con2fb_map[vc->vc_num]]->fbcon_par->p->userfont (which was
set to non-zero) instead of fb_display[vc->vc_num].userfont (which remains
zero for that display).
We could remove tricky userfont flag [2], for we can determine it by
comparing address of the font data and addresses of built-in font data.
But since that commit is failing to fix the original OOB read [3], this
patch keeps the change minimal in case we decide to revert altogether.

Yunhai Zhang recently fixed a VGA software scrollback bug in commit
ebfdfeeae8c0 ("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.

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 using legacy PCI power management .suspend()/.resume() callbacks
have to manage PCI states and device's PM states themselves. They also
need to take care of standard configuration registers.
Switch to generic power management framework using a "struct dev_pm_ops"
variable to take the unnecessary load from the driver.
This also avoids the need for the driver to directly call most of the PCI
helper functions and device power state control functions, as through
the generic framework PCI Core takes care of the necessary operations,
and drivers are required to do only device-specific jobs.

Fixes commit 42ddb453a0cd ("radeon: Conditionally compile PM code")
Before the above mentioned patch, codes between the line number 547 and
2803 were already inside "#ifdef CONFIG_PM" container. Thus, addition of
"#if defined(CONFIG_PM)" was not required in the patch. It also affected
the "#ifdef CONFIG_PPC_OF" container (line 1943-2510).
From the current snapshot of radeon_pm.c, remove:
1434 | #if defined(CONFIG_PM)
and,
2213 | #endif
This removes the redundant CONFIG_PM directive as well as fixes the
CONFIG_PPC (earlier CONFIG_PPC_OF) container.

par->vgapass is a u8, so if we are assuming that buf is at least
PAGE_SIZE then the extra checking is pointless.

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.

- Rename the callback as savagefb_suspend_late() and preserve the

- Define 3 new callbacks as:
* savagefb_suspend()

* savagefb_hibernate()
which in turn call savagefb_suspend_late() by passing appropriate value
for "pm_message_t" type parameter.
- Bind the callbacks in "struct dev_pm_ops" type variable

Clang static analysis reports this representative error
init.c:2501:18: warning: Array access (from variable 'queuedata') results

templ |= ((queuedata[i] & 0xc0) << 3);
This is the problem block of code

if(SiS_Pr->ChipType == SIS_730) {
queuedata = &FQBQData730[0];
} else {
queuedata = &FQBQData[0];
}
} else {
}
queuedata is not set in the else block
Reviewing the old code, the arrays FQBQData730 and FQBQData were
used directly.
So hoist the setting of queuedata out of the if-else block.
