[ Upstream commit b330f3972f4f2a829d41fb9e9b552bec7d73a840 ]
When the compiler decides not to inline the Chunky-to-Planar core
functions, the build fails with:
c2p_planar.c:(.text+0xd6): undefined reference to `c2p_unsupported'
c2p_planar.c:(.text+0x1dc): undefined reference to `c2p_unsupported'
c2p_iplan2.c:(.text+0xc4): undefined reference to `c2p_unsupported'
c2p_iplan2.c:(.text+0x150): undefined reference to `c2p_unsupported'
Fix this by marking the functions __always_inline.
While this could be triggered before by manually enabling both
CONFIG_OPTIMIZE_INLINING and CONFIG_CC_OPTIMIZE_FOR_SIZE, it was exposed
in the m68k defconfig by commit ac7c3e4ff401b304 ("compiler: enable
CONFIG_OPTIMIZE_INLINING forcibly").
Fixes: 9012d011660ea5cf ("compiler: allow all arches to enable CONFIG_OPTIMIZE_INLINING")

[ Upstream commit dd9782834dd9dde3624ff1acea8859f3d3e792d4 ]
The page_offset was only applied to the end of the page range. This caused
the display updates to cause a scrolling effect on the display because the
amount of data written to the display did not match the range display
expected.

commit 51677dfcc17f88ed754143df670ff064eae67f84 upstream.
For various reasons, at least with x86 EFI firmwares, the xoffset and
yoffset in the BGRT info are not always reliable.
Extensive testing has shown that when the info is correct, the
BGRT image is always exactly centered horizontally (the yoffset variable
is more variable and not always predictable).
This commit simplifies / improves the bgrt_sanity_check to simply
check that the BGRT image is exactly centered horizontally and skips
(re)drawing it when it is not.
This fixes the BGRT image sometimes being drawn in the wrong place.

With commit 88ba95bedb79 ("backlight: pwm_bl: Compute brightness of
LED linearly to human eye") the number of set bits (aka hweight())
in the PWM period is used in the heuristic to determine the number
of brightness levels, when the brightness table isn't specified in
the DT. The number of set bits doesn't provide a reliable clue about
the length of the period, instead change the heuristic to:
nlevels = period / fls(period)
Also limit the maximum number of brightness levels to 4096 to avoid
excessively large tables.
With this the number of levels increases monotonically with the PWM
period, until the maximum of 4096 levels is reached:
period (ns) # levels
100 16
500 62
1000 111
5000 416
10000 769
50000 3333

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = devm_kzalloc(dev, size, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL);
Notice that, in this case, variable size is not necessary, hence it
is removed.
This code was detected with the help of Coccinelle.

Starting with ACPI 6.2 bits 1 and 2 of the BGRT status field are no longer
reserved. These bits are now used to indicate if the image needs to be
rotated before being displayed.
The efifb code does not support rotating the image before copying it to
the screen.
This commit adds a check for these new bits and if they are set leaves the
fb contents as is instead of trying to use the un-rotated BGRT image.

When the driver is built-in for PCI, we reference the exit function
after discarding it:
`pvr2fb_pci_exit' referenced in section `.ref.data' of drivers/video/fbdev/pvr2fb.o: defined in discarded section `.exit.text' of drivers/video/fbdev/pvr2fb.o
Just remove the __exit annotation as the easiest workaround.
Also apply the same workaround for pvr2fb_dc_exit().

The kbuild documentation clearly shows that the documents
there are written at different times: some use markdown,
some use their own peculiar logic to split sections.
Convert everything to ReST without affecting too much
the author's style and avoiding adding uneeded markups.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

These are actually fbcon ioctls which just happen to be exposed
through /dev/fb*. They completely ignore which fb_info they're called
on, and I think the userspace tool even hardcodes to /dev/fb0.
Hence just forward the entire thing to fbcon.c wholesale.
Note that this patch drops the fb_lock/unlock on the set side. Since
the ioctl can operate on any fb (as passed in through
con2fb.framebuffer) this is bogus. Also note that fbcon.c in general
never calls fb_lock on anything, so this has been badly broken
already.
With this the last user of the fbcon notifier callback is gone, and we
can garbage collect that too.
v2: add missing uaccess.h include (alpha fails to compile otherwise),
reported by kbuild.
v3: Remember to also drop the #defines (Maarten)
v4: Add the static inline to dummy functions.

Create a new wrapper function for this, feels like there's some
refactoring room here between the two modes.
v2: backlight notifier is also interested in the mode change event,
it calls lcd->set_mode, of which there are 3 implementations. Thanks
to Maarten for spotting this. So we keep that. We can ditch the differentiation
between mode change and all mode changes (because backlight notifier
doesn't care), and we can drop the FBINFO_MISC_USEREVENT stuff too,
because that's just to prevent recursion between fbmem.c and fbcon.c.
While at it flatten the control flow a bit.
v3: Need to add a static inline to the dummy function.

Instead of wiring almost everything down to the very last line using
goto soup (but not consistently, where would the fun be otherwise)
drop out early when checks fail. This allows us to flatten the huge
indent levels to just 1.
Aside: If a driver doesn't set ->fb_check_var, then FB_ACTIVATE_NOW
does nothing. This bug exists ever since this code was extracted as a
common helper in 2002, hence I decided against fixing it. Everyone
just better have a fb_check_var to make sure things work correctly.

There's a callchain of:
fbcon_fb_blanked -> do_(un)blank_screen -> consw->con_blank
-> fbcon_blank -> fb_blank
Things don't go horribly wrong because the BKL console_lock safes the
day, but that's about it. And the seeming recursion is broken in 2
ways:
- Starting from the fbdev ioctl we set FBINFO_MISC_USEREVENT, which
tells the fbcon_blank code to not call fb_blank. This was required
to not deadlock when recursing on the fb_notifier_chain mutex.
- Starting from the con_blank hook we're getting saved by the
console_blanked checks in do_blank/unblank_screen. Or at least
that's my theory.
Anyway, recursion isn't awesome, so let's stop it. Breaking the
recursion avoids the need to be in the FBINFO_MISC_USEREVENT critical
section, so lets move it out of that too.
The astute reader will notice that fb_blank seems to require
lock_fb_info(), which the fbcon code seems to ignore. I have no idea
how to fix that problem, so let's keep ignoring it.
v2: I forgot the sysfs blanking code.
v3: Fix typo in callchain in the commmit message (Sam).

This reverts commit 994efacdf9a087b52f71e620b58dfa526b0cf928.
The justification is that if hw blanking fails (i.e. fbops->fb_blank)
fails, then we still want to shut down the backlight. Which is exactly
_not_ what fb_blank() does and so rather inconsistent if we end up
with different behaviour between fbcon and direct fbdev usage. Given
that the entire notifier maze is getting in the way anyway I figured
it's simplest to revert this not well justified commit.
