Remove any unused macros.
Cleanup indenting in the .h file.
drivers/staging/sm7xxfb/sm7xxfb.c:821 smtcfb_pci_probe() warn: 'smtc_regbaseaddress' can't be NULL.
move the BIG_ENDIAN ifdefs to the .h file. I don't understand why only
big endian systems get a fb_read/write? Cleanup casts in fb_read/write.
cleanup comments. make sure they are up to date and make sense.
cleanup function declarations. Make the style consistent.
run checkpatch.pl --strict
Remind me we need the #ifndef MODULE?

I believe it is completely fair for some maintainers to take the
position of what the documentation used to say prior to the new
documentation patch on queue for v4.2, but note that that is an old
position and I seriously caution against it. A few reasons I caution
against it:
1) It used to be believed that EXPORT_SYMBOL_GPL() was pretty
pointless by many maintainers and developers -- in particular for all
those who have always written even EXPORT_SYMBOL() code with the same
intent as EXPORT_SYMBOL_GPL(). Experience and comments with attorneys
even on Linus' part reflects that there is a huge legal value to
EXPORT_SYMBOL_GPL() [0].
The skinny: Intent matters a lot and "circumventing a GPL-only export
requires an explicit action, making it clear that the resulting
copyright infringement was a deliberate act".
Naturally lax positions on the matter over use of EXPORT_SYMBOL_GPL()
have evolved over time then, not only about its value but also then as
a consequence about where its used in practice today by maintainers
and developers in different trees.
[0] https://lwn.net/Articles/154602/
2) The old position of use of EXPORT_SYMBOL_GPL() about the
derivatives work punts onto the maintainer the onus over the question
of derivatives work -- such question really should not be taken
lightly and this responsibility should really not fall onto the
developer, it requires attorney involvement and should not be taken
lightly by any means.
3) Most drivers are upstream these days, we want to avoid bug reports
from crappy proprietary drivers, specially as we add new features. We
don't have to be begging vendors to work upstream these days, that's
rather the norm. The landscape has changed dramatically. Even Linus
has told Nvidia to go fuck themselves lately, bravo.

Those are two old APIs, and quite the contrary, as I noted we have a
series of new PAT APIs that old modules did not use that are now being
added and spread into the kernel onto which upstream maintainers have
been insisting on using EXPORT_SYMBOL_GPL() even though older similar
APIs only used EXPORT_SYMBOL(). As a recent example the family of APIs
set_pages_array_xx() are all EXPORT_SYMBOL() but Toshi's new
set_pages_array_wt() was asked to be changed to EXPORT_SYMBOL_GPL()
because as noted by Ingo:
--------------
By default we make new APIs EXPORT_SYMBOL_GPL():
we don't want proprietary modules mucking around with new code
PAT interfaces, we only want modules we can analyze and fix
in detail.

Its not just me as I note above, and the new APIs I'm introducing are
also to help with PAT usage.
> That makes for a messy environment to work in, and it's messy enough already.
You're right about the mismatch over the kernel and even on a set of
family of APIs, that's a fair argument, but *that* is a very different
problem. Also the "messy environment" you describe is for proprietary
drivers and it always has been a messy environment for them, that's on
them and they should be talking to attorneys! The issue is already
super messy for them considering tons of folks using EXPORT_SYMBOL()
with the same intent as EXPORT_SYMBOL_GPL(), and refusing to use
EXPORT_SYMBOL_GPL() because of this.

You're not the only one who has argued over this and the misfortune
over the naming used for EXPORT_SYMBOL_GPL(). Christoph made a similar
argument recently and provided some technical ideas on how to improve
the situation with symbol groups to reflect more of what was intended.
I also followed up with some further possibilities of how to do that
work [1]. If we really care about this so much perhaps we should talk
about this as a separate topic and address it but I would strongly
prefer to avoid this discussion at this point on this thread. If we
really want to we can talk about it over beers at Plumbers perhaps.

> But as long as we keep it, I think it should mean something more than the preference of the author.
We extend the documentation as things become relevant and as you noted
to help with guidance, we did just that recently upon your request and
I provided basis for why things have changed over time now, as well as
reasoning by other maintainers on PAT interfaces, I hope this helps
clarify things.

I appreciate your thoroughness over this matter and patience. I hope I
have provided new information to help you reconsider. Contrary to the
old days where we needed more of technical reason to use
EXPORT_SYMBOL_GPL() since its use has proven to have huge value, I
personally will always prefer to *always* use EXPORT_SYMBOL_GPL() for
all *new* exported symbols, unless explicitly told by the maintainer,
and even if they do ask for me to use EXPORT_SYMBOL_GPL() obviously
my intent remains the same, and no one can change that. These days
maintainer's don't ask me to change EXPORT_SYMBPOL_GPL() to
EXPORT_SYMBOL() though, and if they do they are of the position that
EXPORT_SYBOL() means the same thing as EXPORT_SYMBOL_GPL(), you're the
first to question this but it seems it was for the lack of guidance we
had to reflect new best practices.
I hope to have provided a bit of new information to help you
reconsider this series to go through you but since you seem to be fine
for this to go through another tree and since I failed to notice that
I should also get Arnd's Ack I am in hopes this might be able to go
through Arnd's tree if not through you. Please let me know, in case I
have to resubmit to Arnd.

Arnd,
After a long-winded conversation with Bjorn over use of
EXPORT_SYMBOL_GPL() instead of EXPORT_SYMBOL() he's noted he'd
be OK if this goes through you as an alternative. This series
goes unmodified from the last posted v6 series, I am just
reposting and addressing this to you now in hopes you might
be comfortable with my use of EXPORT_SYMBOL_GPL() on new
PAT interfaces. I use EXPORT_SYMBOL_GPL() for new PAT symbols,
this parallels Ingo's stated preference as "we don't want
proprietary modules mucking around with new code PAT interfaces,
we only want modules we can analyze and fix in detail" [1].
Other than this Bjorn seemed comfortable with the series and
even had provided an Ack to the series, the EXPORT_SYMBOL_GPL()
thing was the ony thing he was not comfortable with, and also
that of the devres change going in with no users yet.
Tomi has already Ack'd the framebuffer driver specific changes
and is comfortable with the driver changes to go through the
tree that the depending symbols depend on.
I typically had submitted two series for these patches but since
the patches are all related and now already Acked I've bundled
them together and rebased them on top of today's linux-next tree.
This series is part of a larger effort to help avoid direct use
of MTRR code and instead replace it with more generic PAT
interfaces, I posted a full description of the entire series
recently [2].
Please let me know if there are any issues.

Convert the driver from using the x86 specific MTRR code to
the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add()
will avoid MTRR if write-combining is available, in order to
take advantage of that also ensure the ioremap'd area is requested
as write-combining.
There are a few motivations for this:
a) Take advantage of PAT when available
b) Help bury MTRR code away, MTRR is architecture specific and on
x86 its replaced by PAT
c) Help with the goal of eventually using _PAGE_CACHE_UC over
_PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
de33c442e titled "x86 PAT: fix performance drop for glx,
use UC minus for ioremap(), ioremap_nocache() and
pci_mmap_page_range()")
The conversion done is expressed by the following Coccinelle
SmPL patch, it additionally required manual intervention to
address all the #ifdery and removal of redundant things which
arch_phys_wc_add() already addresses such as verbose message
about when MTRR fails and doing nothing when we didn't get
an MTRR.

From: "Luis R. Rodriguez" <mcgrof@suse.com>
Convert the driver from using the x86 specific MTRR code to
the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add()
will avoid MTRR if write-combining is available, in order to
take advantage of that also ensure the ioremap'd area is requested
as write-combining.
There are a few motivations for this:
a) Take advantage of PAT when available
b) Help bury MTRR code away, MTRR is architecture specific and on
x86 its replaced by PAT
c) Help with the goal of eventually using _PAGE_CACHE_UC over
_PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
de33c442e titled "x86 PAT: fix performance drop for glx,
use UC minus for ioremap(), ioremap_nocache() and
pci_mmap_page_range()")
The conversion done is expressed by the following Coccinelle
SmPL patch, it additionally required manual intervention to
address all the #ifdery and removal of redundant things which
arch_phys_wc_add() already addresses such as verbose message
about when MTRR fails and doing nothing when we didn't get
an MTRR.

The driver doesn't use mtrr_add() or arch_phys_wc_add() but
since we know the framebuffer is isolated already on an
ioremap() we can take advantage of write combining for
performance where possible.
In this case there are a few motivations for this:
a) Take advantage of PAT when available
b) Help with the goal of eventually using _PAGE_CACHE_UC over
_PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit

From: "Luis R. Rodriguez" <mcgrof@suse.com>
PCI BARs tell us whether prefetching is safe, but they don't say anything
about write combining (WC). WC changes ordering rules and allows writes to
be collapsed, so it's not safe in general to use it on a prefetchable
region.
Add pci_iomap_wc() and pci_iomap_wc_range() so drivers can take advantage
of write combining when they know it's safe.
On architectures that don't fully support WC, e.g., x86 without PAT,
drivers for legacy framebuffers may get some of the benefit by using
arch_phys_wc_add() in addition to pci_iomap_wc(). But arch_phys_wc_add()
is unreliable and should be avoided in general. On x86, it uses MTRRs,
which are limited in number and size, so the results will vary based on
driver loading order.
The goals of adding pci_iomap_wc() are to:
- Give drivers an architecture-independent way to use WC so they can stop
using interfaces like mtrr_add() (on x86, pci_iomap_wc() uses
PAT when available)
- Move toward using _PAGE_CACHE_MODE_UC, not _PAGE_CACHE_MODE_UC_MINUS,
on x86 on ioremap_nocache() (see de33c442ed2a ("x86 PAT: fix
performance drop for glx, use UC minus for ioremap(), ioremap_nocache()
and pci_mmap_page_range()")

* [PATCH v7 7/9] video: fbdev: arkfb: use arch_phys_wc_add() and pci_iomap_wc()

In-Reply-To: <1434751712-24333-1-git-send-email-mcgrof@do-not-panic.com>
From: "Luis R. Rodriguez" <mcgrof@suse.com>
Convert the driver from using the x86 specific MTRR code to
the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add()
will avoid MTRR if write-combining is available, in order to
take advantage of that also ensure the ioremap'd area is requested
as write-combining.
There are a few motivations for this:
a) Take advantage of PAT when available
b) Help bury MTRR code away, MTRR is architecture specific and on
x86 its replaced by PAT
c) Help with the goal of eventually using _PAGE_CACHE_UC over
_PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
de33c442e titled "x86 PAT: fix performance drop for glx,
use UC minus for ioremap(), ioremap_nocache() and
pci_mmap_page_range()")
The conversion done is expressed by the following Coccinelle
SmPL patch, it additionally required manual intervention to
address all the #ifdery and removal of redundant things which
arch_phys_wc_add() already addresses such as verbose message
about when MTRR fails and doing nothing when we didn't get
an MTRR.

* [PATCH] staging: sm750fb: use tabs for indentation
From: Juston Li @ 2015-06-20 0:50 UTC (permalink / raw)
To: sudipm.mukherjee, teddy.wang, gregkh, linux-fbdev, devel,
linux-kernel
Cc: Juston Li
Replace spaces with tabs for indentation to fix the checkpatch.pl warning
'WARNING: please, no spaces at the start of a line'
checkpatch doesn't catch comments indented by spaces but I fixed comments
adjacent to warnings as well so they would remain aligned.

* [PATCH v2] staging: sm750fb: use tabs for indentation
From: Juston Li @ 2015-06-20 5:13 UTC (permalink / raw)
To: sudipm.mukherjee, teddy.wang, gregkh, linux-fbdev, devel,
linux-kernel
Cc: Juston Li
Replace spaces with tabs for indentation to fix the checkpatch.pl warning
'WARNING: please, no spaces at the start of a line'
checkpatch doesn't catch comments indented by spaces but I fixed comments
adjacent to warnings as well so they would remain aligned.
Changes since v1:
fix alignment in ddk750_display.c:154
didn't remove a space in ddk750_hwi2c.c:48

Replace spaces with tabs for indentation to fix the checkpatch.pl warning
'WARNING: please, no spaces at the start of a line'
checkpatch doesn't catch comments indented by spaces but I fixed comments
adjacent to warnings as well so they would remain aligned.
