fbdev: fbmem: convert CONFIG_FB_LOGO_CENTER into a cmd line option
A command line option is much more flexible than a config option and the supporting code is small. Gets rid of #ifdefs in the code too...

omap2fb: Fix stack memory disclosure
Using [1] for static analysis I found that the OMAPFB_QUERY_PLANE,
OMAPFB_GET_COLOR_KEY, OMAPFB_GET_DISPLAY_INFO, and OMAPFB_GET_VRAM_INFO
cases could all leak uninitialized stack memory--either due to
uninitialized padding or 'reserved' fields.
Fix them by clearing the shared union used to store copied out data.

Remove 'type' argument from access_ok() function
Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument
of the user address range verification function since we got rid of the
old racy i386-only code to walk page tables by hand.
It existed because the original 80386 would not honor the write protect
bit when in kernel mode, so you had to do COW by hand before doing any
user access. But we haven't supported that in a long time, and these
days the 'type' argument is a purely historical artifact.
A discussion about extending 'user_access_begin()' to do the range
checking resulted this patch, because there is no way we're going to
move the old VERIFY_xyz interface to that model. And it's best done at
the end of the merge window when I've done most of my merges, so let's
just get this done once and for all.
This patch was mostly done with a sed-script, with manual fix-ups for
the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form.
There were a couple of notable cases:
- csky still had the old "verify_area()" name as an alias.
- the iter_iov code had magical hardcoded knowledge of the actual
values of VERIFY_{READ,WRITE} (not that they mattered, since nothing
really used it)
- microblaze used the type argument for a debug printout
but other than those oddities this should be a total no-op patch.
I tried to fix up all architectures, did fairly extensive grepping for
access_ok() uses, and the changes are trivial, but I may have missed
something. Any missed conversion should be trivially fixable, though.

Pull Devicetree updates from Rob Herring:
"The biggest highlight here is the start of using json-schema for DT
bindings. Being able to validate bindings has been discussed for years
with little progress.
- Initial support for DT bindings using json-schema language. This is
the start of converting DT bindings from free-form text to a
structured format.
- Reworking of initrd address initialization. This moves to using the
phys address instead of virt addr in the DT parsing code. This
rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary
rebuilding of lots of files.
- Fix stale phandle entries in phandle cache
- DT overlay validation improvements. This exposed several memory
leak bugs which have been fixed.
- Use node name and device_type helper functions in DT code
- Last remaining conversions to using %pOFn printk specifier instead
of device_node.name directly
- Create new common RTC binding doc and move all trivial RTC devices
out of trivial-devices.txt.

PHY, and Xen shared memory

fbdev: fbcon: Fix unregister crash when more than one framebuffer
When unregistering fbdev using unregister_framebuffer(), any bound
console will unbind automatically. This is working fine if this is the
only framebuffer, resulting in a switch to the dummy console. However if
there is a fb0 and I unregister fb1 having a bound console, I eventually
get a crash. The fastest way for me to trigger the crash is to do a
reboot, resulting in this splat:

The problem is in the console rebinding in fbcon_fb_unbind(). It uses the
virtual console index as the new framebuffer index to bind the console(s)
to. The correct way is to use the con2fb_map lookup table to find the
framebuffer index.

fbdev: Remove depends on HAS_DMA in case of platform dependency
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing.

fbdev: fbmem: behave better with small rotated displays and many CPUs
Blitting an image with "negative" offsets is not working since there is no clipping. It hopefully just crashes. For the bootup logo, there is protection so that blitting does not happen as the image is drawn further and further to the right (ROTATE_UR) or further and further down (ROTATE_CW). There is however no protection when drawing in the opposite directions (ROTATE_UD and ROTATE_CCW). Add back this protection. The regression is 20-odd years old but the mindless warning-killing mentality displayed in commit |

udlfb: fix some inconsistent NULL checking
In the current kernel, then kzalloc() can't fail for small allocations,
but if it did fail then we would have a NULL dereference in the error
handling. Also in dlfb_usb_disconnect() if "info" were NULL then it
would cause an Oops inside the unregister_framebuffer() function but it
can't be NULL so let's remove that check.

backlight: pwm_bl: Fix brightness levels for non-DT case.
Commit '88ba95bedb79 ("backlight: pwm_bl: Compute brightness of LED
linearly to human eye")' allows the possibility to compute a default
brightness table when there isn't the brightness-levels property in the
DT. Unfortunately the changes made broke the pwm backlight for the
non-DT boards.
Usually, the non-DT boards don't pass the brightness levels via platform
data, instead, it sets the max_brightness in their platform data and the
driver calculates the level without a table. The offending patch assumed
that when there is no brightness levels table we should create one, but this
is clearly wrong for the non-DT case.
After this patch the code handles the DT and the non-DT case taking in
consideration also if max_brightness is set or not.

powerpc updates for 4.20
Notable changes:
- A large series to rewrite our SLB miss handling, replacing a lot of fairly
complicated asm with much fewer lines of C.
- Following on from that, we now maintain a cache of SLB entries for each
process and preload them on context switch. Leading to a 27% speedup for our
context switch benchmark on Power9.
- Improvements to our handling of SLB multi-hit errors. We now print more debug
information when they occur, and try to continue running by flushing the SLB
and reloading, rather than treating them as fatal.
- Enable THP migration on 64-bit Book3S machines (eg. Power7/8/9).
- Add support for physical memory up to 2PB in the linear mapping on 64-bit
Book3S. We only support up to 512TB as regular system memory, otherwise the
percpu allocator runs out of vmalloc space.
- Add stack protector support for 32 and 64-bit, with a per-task canary.
- Add support for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.
- Support recognising "big cores" on Power9, where two SMT4 cores are presented
to us as a single SMT8 core.
- A large series to cleanup some of our ioremap handling and PTE flags.
- Add a driver for the PAPR SCM (storage class memory) interface, allowing
guests to operate on SCM devices (acked by Dan).
- Changes to our ftrace code to handle very large kernels, where we need to use
a trampoline to get to ftrace_caller().
Many other smaller enhancements and cleanups.

Devicetree updates for 4.20:
- Sync dtc with upstream version v1.4.7-14-gc86da84d30e4
- Work to get rid of direct accesses to struct device_node name and
type pointers in preparation for removing them. New helpers for
parsing DT cpu nodes and conversions to use the helpers. printk
conversions to %pOFn for printing DT node names. Most went thru
subystem trees, so this is the remainder.
- Fixes to DT child node lookups to actually be restricted to child
nodes instead of treewide.
- Refactoring of dtb targets out of arch code. This makes the support
more uniform and enables building all dtbs on c6x, microblaze, and
powerpc.
- Various DT binding updates for Renesas r8a7744 SoC
- Vendor prefixes for Facebook, OLPC
- Restructuring of some ARM binding docs moving some peripheral bindings
out of board/SoC binding files
- New "secure-chosen" binding for secure world settings on ARM
- Dual licensing of 2 DT IRQ binding headers

drivers/video/fbdev: use ioremap_wc/wt() instead of __ioremap()
_PAGE_NO_CACHE is a platform specific flag. In addition, this flag is misleading because one would think it requests a noncached page whereas a noncached page is _PAGE_NO_CACHE | _PAGE_GUARDED _PAGE_NO_CACHE alone means write combined noncached page, so lets use ioremap_wc() instead. _PAGE_WRITETHRU is also platform specific flag. Use ioremap_wt() instead.

backlight: pwm_bl: Switch to using "atomic" PWM API
The "atomic" API allows us to configure PWM period and duty_cycle and enable it in one call.

fbdev: fix broken menu dependencies
The framebuffer options and devices menu is unintentionally split or broken because some items in it do not depend on FB (including several under omap and mmp). Fix this by moving FB_CMDLINE, FB_NOTIFY, and FB_CLPS711X_OLD to just before the FB Kconfig symbol definition and by moving the omap, omap2, and mmp menus to last, following FB_SM712. Also, the FB_VIA dependencies are duplicated by both being inside an "if FB_VIA/endif" block and "depends on FB_VIA", so drop the "depends on FB_VIA" lines since they are redundant. Fixes: |

video: fbdev: sis: Remove unnecessary parentheses and commented code
Clang warns when multiple pairs of parentheses are used for a single
conditional statement.
drivers/video/fbdev/sis/init301.c:851:42: warning: equality comparison
with extraneous parentheses [-Wparentheses-equality]

1 warning generated.
Remove the parentheses and while we're at it, clean up the commented
code, which has been here since the beginning of git history.

video: fbdev: omapfb: lcd_ams_delta: use GPIO lookup table
Now as Amstrad Delta board - the only user of this driver - provides GPIO lookup tables, switch from GPIO numbers to GPIO descriptors and use the table to locate required GPIO pins. Declare static variables for storing GPIO descriptors and replace gpio_ function calls with their gpiod_ equivalents. Move GPIO lookup to the driver probe function so device initialization can be deferred instead of aborted if a GPIO pin is not yet available. Pin naming used by the driver should be followed while respective GPIO lookup table is initialized by a board init code.
