Pull tty/serial driver updates from Greg KH:
"Here is the big set of tty and serial driver patches for 4.17-rc1
Not all that big really, most are just small fixes and additions to

well.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pul removal of obsolete architecture ports from Arnd Bergmann:
"This removes the entire architecture code for blackfin, cris, frv,
m32r, metag, mn10300, score, and tile, including the associated device
drivers.
I have been working with the (former) maintainers for each one to
ensure that my interpretation was right and the code is definitely
unused in mainline kernels. Many had fond memories of working on the
respective ports to start with and getting them included in upstream,
but also saw no point in keeping the port alive without any users.
In the end, it seems that while the eight architectures are extremely
different, they all suffered the same fate: There was one company in
charge of an SoC line, a CPU microarchitecture and a software
ecosystem, which was more costly than licensing newer off-the-shelf
CPU cores from a third party (typically ARM, MIPS, or RISC-V). It
seems that all the SoC product lines are still around, but have not
used the custom CPU architectures for several years at this point. In
contrast, CPU instruction sets that remain popular and have actively
maintained kernel ports tend to all be used across multiple licensees.
[ See the new nds32 port merged in the previous commit for the next
generation of "one company in charge of an SoC line, a CPU
microarchitecture and a software ecosystem" - Linus ]
The removal came out of a discussion that is now documented at
https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
marking any ports as deprecated but remove them all at once after I
made sure that they are all unused. Some architectures (notably tile,
mn10300, and blackfin) are still being shipped in products with old
kernels, but those products will never be updated to newer kernel
releases.
After this series, we still have a few architectures without mainline
gcc support:
- unicore32 and hexagon both have very outdated gcc releases, but the
maintainers promised to work on providing something newer. At least
in case of hexagon, this will only be llvm, not gcc.
- openrisc, risc-v and nds32 are still in the process of finishing
their support or getting it added to mainline gcc in the first
place. They all have patched gcc-7.3 ports that work to some
degree, but complete upstream support won't happen before gcc-8.1.
Csky posted their first kernel patch set last week, their situation
will be similar
[ Palmer Dabbelt points out that RISC-V support is in mainline gcc
since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]"
This really says it all:

Cast _pitch_ to u64 in order to give the compiler complete information
about the proper arithmetic to use. Notice that this variable is
being used in a context that expects an expression of type u64
(64 bits, unsigned).
The expression pitch * var->yres_virtual is currently being evaluated
using 32-bit arithmetic and the result of the operation is being stored
into variable mem, which is a variable of type u64. Based on that,
chances are there is a potential integer overflow as a result of the
operation.

CONFIG_FB_RADEON=m
The offb driver takes precedence over module radeonfb. It is then
impossible to load the module, error reported is:

Building with LTO enabled reveals some functions whose prototypes
in the header are different from the definition:
drivers/video/fbdev/sis/sis_main.h:765:0: error: type of 'SiS_SetCH70xxANDOR' does not match original declaration [-Werror=lto-type-mismatch]
extern void SiS_SetCH70xxANDOR(struct SiS_Private *SiS_Pr, unsigned short reg,
drivers/video/fbdev/sis/init301.c:8937:0: note: type mismatch in parameter 4
SiS_SetCH70xxANDOR(struct SiS_Private *SiS_Pr, unsigned short reg,
drivers/video/fbdev/sis/init301.c:8937:0: note: type 'short unsigned int' should match type 'unsigned char'
drivers/video/fbdev/sis/init301.c:8937:0: note: 'SiS_SetCH70xxANDOR' was previously declared here
The root cause appears to be the way that header files are used in this
driver, where they contain both static variable and declarations for
symbols in other files.
To clean that up, I'm changing all mixed headers to only contain
declarations the way we normally do in C, or contain only static
variables, and move the rest to a more appropriate place. Once that
is done, the headers can be included in the other files as well, and
guarantee that the prototypes match.
There are a few headers that now only contain static variables, and
I'm leaving those alone here as the patch is already too big. These
could be trivially moved into the respective .c files.

sbusfb_ioctl_helper().
Fixing arbitrary kernel leak in case FBIOGETCMAP_SPARC in
sbusfb_ioctl_helper().
'index' is defined as an int in sbusfb_ioctl_helper().
We retrieve this from the user:
if (get_user(index, &c->index) ||
__get_user(count, &c->count) ||
__get_user(ured, &c->red) ||
__get_user(ugreen, &c->green) ||
__get_user(ublue, &c->blue))
return -EFAULT;
and then we use 'index' in the following way:
red = cmap->red[index + i] >> 8;
green = cmap->green[index + i] >> 8;
blue = cmap->blue[index + i] >> 8;
This is a classic information leak vulnerability. 'index' should be
an unsigned int, given its usage above.
This patch is straight-forward; it changes 'index' to unsigned int
in two switch-cases: FBIOGETCMAP_SPARC && FBIOPUTCMAP_SPARC.
This patch fixes CVE-2018-6412.

The omapfb driver fails to build after commit 23c35f48f5fb
("pinctrl: remove include file from <linux/device.h>") because it
relies on the <linux/pinctrl/consumer.h> and <linux/seq_file.h>
being pulled in by the <linux/device.h> header implicitly.
Include these headers explicitly to avoid the build failures.

"This seems to have been a comparatively quieter merge window, I assume
due to holidays etc. The "biggest" change is AMD header cleanups, which
merge/remove a bunch of them. The AMD gpu scheduler is now being made generic
with the etnaviv driver wanting to reuse the code, hopefully other drivers
can go in the same direction.
Otherwise it's the usual lots of stuff in i915/amdgpu, not so much stuff
elsewhere.
Core:
- Add .last_close and .output_poll_changed helpers to reduce driver footprints
- Fix plane clipping
- Improved debug printing support
- Add panel orientation property
- Update edid derived properties at edid setting
- Reduction in fbdev driver footprint
- Move amdgpu scheduler into core for other drivers to use.
i915:

- Display planes cleanup
- New PMU interface for perf queries
- New firmware support for KBL/SKL
- Geminilake HW workaround for perforamce
- Coffeelake stolen memory improvements
- GPU reset robustness work
- Cannonlake horizontal plane flipping
- GVT work
amdgpu/radeon:
- RV and Vega header file cleanups (lots of lines gone!)
- TTM operation context support
- 48-bit GPUVM support for Vega/RV
- ECC support for Vega
- Resizeable BAR support
- Multi-display sync support
- Enable swapout for reserved BOs during allocation
- S3 fixes on Raven
- GPU reset cleanup and fixes
- 2+1 level GPU page table
