Masahiro Yamada a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Mike Rapoport e31cf2f4ca mm: don't include asm/pgtable.h if linux/mm.h is already included
Patch series "mm: consolidate definitions of page table accessors", v2.

The low level page table accessors (pXY_index(), pXY_offset()) are
duplicated across all architectures and sometimes more than once.  For
instance, we have 31 definition of pgd_offset() for 25 supported
architectures.

Most of these definitions are actually identical and typically it boils
down to, e.g.

static inline unsigned long pmd_index(unsigned long address)
{
        return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1);
}

static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
{
        return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
}

These definitions can be shared among 90% of the arches provided
XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined.

For architectures that really need a custom version there is always
possibility to override the generic version with the usual ifdefs magic.

These patches introduce include/linux/pgtable.h that replaces
include/asm-generic/pgtable.h and add the definitions of the page table
accessors to the new header.

This patch (of 12):

The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the
functions involving page table manipulations, e.g.  pte_alloc() and
pmd_alloc().  So, there is no point to explicitly include <asm/pgtable.h>
in the files that include <linux/mm.h>.

The include statements in such cases are remove with a simple loop:

	for f in $(git grep -l "include <linux/mm.h>") ; do
		sed -i -e '/include <asm\/pgtable.h>/ d' $f
	done

Linus Torvalds 7ae77150d9 powerpc updates for 5.8
- Support for userspace to send requests directly to the on-chip GZIP
    accelerator on Power9.
 
  - Rework of our lockless page table walking (__find_linux_pte()) to make it
    safe against parallel page table manipulations without relying on an IPI for
    serialisation.
 
  - A series of fixes & enhancements to make our machine check handling more
    robust.
 
  - Lots of plumbing to add support for "prefixed" (64-bit) instructions on
    Power10.
 
  - Support for using huge pages for the linear mapping on 8xx (32-bit).
 
  - Remove obsolete Xilinx PPC405/PPC440 support, and an associated sound driver.
 
  - Removal of some obsolete 40x platforms and associated cruft.
 
  - Initial support for booting on Power10.
 
  - Lots of other small features, cleanups & fixes.

Michal Simek 7ade8495dc powerpc: Remove Xilinx PPC405/PPC440 support
The latest Xilinx design tools called ISE and EDK has been released in
October 2013. New tool doesn't support any PPC405/PPC440 new designs.
These platforms are no longer supported and tested.

PowerPC 405/440 port is orphan from 2013 by
commit cdeb89943b ("MAINTAINERS: Fix incorrect status tag") and
commit 19624236cc ("MAINTAINERS: Update Grant's email address and maintainership")
that's why it is time to remove the support fot these platforms.

UAPI Changes:

- drm/i915: Show per-engine default property values in sysfs

    By providing the default values configured into the kernel via sysfs, it
    is much more convenient for userspace to restore those sane defaults, or
    at least know what are considered good baseline. This is useful, for
    example, to cleanup after any failed userspace prior to commencing new

Gwan-gyeong Mun f45ce9336f video/hdmi: Add Unpack only function for DRM infoframe
It adds an unpack only function for DRM infoframe for dynamic range and
mastering infoframe readout.
It unpacks the information data block contained in the binary buffer into
a structured frame of the HDMI Dynamic Range and Mastering (DRM)
information frame.

In contrast to hdmi_drm_infoframe_unpack() function, it does not verify
a checksum.

It can be used for unpacking a DP HDR Metadata Infoframe SDP case.
DP HDR Metadata Infoframe SDP uses the same Dynamic Range and Mastering
(DRM) information (CTA-861-G spec.) such as HDMI DRM infoframe.
But DP SDP header and payload structure are different from HDMI DRM
Infoframe. Therefore unpacking DRM infoframe for DP requires skipping of
a verifying checksum.

v9: Add clear comments to hdmi_drm_infoframe_unpack_only() and
    hdmi_drm_infoframe_unpack() (Laurent Pinchart)

This converts the l4f00242t03 backlight driver to use GPIO
descriptors and switches the two Freescale i.MX boards over
to passing descriptors instead of global GPIO numbers.

We use the typical names "enable" and "reset" as found in
the device tree bindings for panel GPIOs.

This saves a lot of code in the driver and makes it possible
to get rid of the platform data header altogether.

Chuhong Yuan 8213fb4187 fbdev: s1d13xxxfb: add missed unregister_framebuffer in remove
The driver calls register_framebuffer() in probe but does not call
unregister_framebuffer() in remove.
Rename current remove to __s1d13xxxfb_remove() for error handler.
Then add a new remove to call unregister_framebuffer().

Uwe Kleine-König 5c694f8094 video: fbdev: imxfb: ensure balanced regulator usage
The fbdev framework doesn't care to call the .set_power callback only on
changes. So the driver has to care for itself that the regulator doesn't
get disabled more often than enabled.

This fixes the regulator warning

	unbalanced disables for lcd supply

which can be triggered by doing

	echo 4 > /sys/class/lcd/imxfb-lcd/lcd_power

twice.

Change the file to just pass the struct by reference, which is
