Simplify things by making the i.MX SDHCI driver just use
slot GPIO with descriptors instead of passing around the global
GPIO numbers that we want to get rid of.
As it turns out, just one single board is using the platform
data to pass in GPIOs numbers for CD and WP, so we augment this
to use a machine descriptor table instead.

The power GPIO line is passed with inversion flags and all from
the platform data. Switch to using an optional GPIO descriptor and
use this to switch the power.
Augment the only boardfile to pass in the proper "power" descriptor
in the GPIO descriptor machine table instead.
As the GPIO handling is now much simpler, we can cut down on some
overhead code.

Modifty the JZ4740 driver to retrieve card detect and write
protect GPIO pins from GPIO descriptors instead of hard-coded
global numbers. Augment the only board file using this in the
process and cut down on passed in platform data.
Preserve the code setting the caps2 flags for CD and WP
as active low or high since the slot GPIO code currently
ignores the gpiolib polarity inversion semantice and uses
the raw accessors to read the GPIO lines, but set the right
polarity flags in the descriptor table for jz4740.

On few SDHCI-MSM controllers, the host controller's clock tuning
circuit may go out of sync if controller clocks are gated which
eventually will result in data CRC, command CRC/timeout errors.
To overcome this h/w limitation, the DLL needs to be re-initialized
and restored with its old settings once clocks are ungated.

Existing data command CRC error handling is non-standard and does not work
with some Intel host controllers. Specifically, the assumption that the host
controller will continue operating normally after the error interrupt,
is not valid. Change the driver to handle the error in the same manner
as a data CRC error, taking care to ensure that the data line reset is
done for single or multi-block transfers, and it is done before

fs/iomap.c: get/put the page in iomap_page_create/release()

mm/sparse: add common helper to mark all memblocks present
mm: introduce common STRUCT_PAGE_MAX_SHIFT define
alpha: fix hang caused by the bootmem removal
The spdxcheck script currently falls over when confronted with a binary
file (such as Documentation/logo.gif). To avoid that, always open files
in binary mode and decode line-by-line, ignoring encoding errors.
One tricky case is when piping data into the script and reading it from
standard input. By default, standard input will be opened in text mode,
so we need to reopen it in binary mode.
The breakage only happens with python3 and results in a
UnicodeDecodeError (according to Uwe).

Right now, checkstack.pl isn't able to print anything on aarch64,
because it won't be able to match the stating objdump line of a function
due to this missing space. Hence, it displays every stack as zero-size.
After this patch, checkpatch.pl is able to match the start of a

migrate_page_move_mapping() expects pages with private data set to have
a page_count elevated by 1. This is what used to happen for xfs through
the buffer_heads code before the switch to iomap in commit 82cb14175e
("xfs: add support for sub-pagesize writeback without buffer_heads").
Not having the count elevated causes move_pages() to fail on memory
mapped files coming from xfs.
Make iomap compatible with the migrate_page_move_mapping() assumption by
elevating the page count as part of iomap_page_create() and lowering it
in iomap_page_release().
It causes the move_pages() syscall to misbehave on memory mapped files
from xfs. It does not not move any pages, which I suppose is "just" a
perf issue, but it also ends up returning a positive number which is out
of spec for the syscall. Talking to Michal Hocko, it sounds like
returning positive numbers might be a necessary update to move_pages()
anyway though
(https://lkml.kernel.org/r/20181116114955.GJ14706@dhcp22.suse.cz).
I only hit this in tests that verify that move_pages() actually moved
the pages. The test also got confused by the positive return from
move_pages() (it got treated as a success as positive numbers were not
expected and not handled) making it a bit harder to track down what's
going on.

The conversion of alpha to memblock as the early memory manager caused
boot to hang as described at [1].
The issue is caused because for CONFIG_DISCTONTIGMEM=y case,
memblock_add() is called using memory start PFN that had been rounded
down to the nearest 8Mb and it caused memblock to see more memory that
is actually present in the system.
Besides, memblock allocates memory from high addresses while bootmem was
using low memory, which broke the assumption that early allocations are
always accessible by the hardware.
This patch ensures that memblock_add() is using the correct PFN for the
memory start and forces memblock to use bottom-up allocations.

arm64: dma-mapping: Fix FORCE_CONTIGUOUS buffer clearing
One notable fix for our change to split pt_regs between user/kernel, we forgot
to update BPF to use the user-visible type which was an ABI break for BPF
programs.
A slightly ugly but minimal fix to do_syscall_trace_enter() so that we use
tracehook_report_syscall_entry() properly. We'll rework the code in next to
avoid the empty if body.
Seven commits fixing bugs in the new papr_scm (Storage Class Memory) driver.
The driver was finally able to be tested on the other hypervisor which exposed
several bugs. The fixes are all fairly minimal at least.
Fix a crash in our MSI code if an MSI-capable device is plugged into a non-MSI
capable PHB, only seen on older hardware (MPC8378).
Fix our legacy serial code to look for "stdout-path" since the device trees were
updated to use that instead of "linux,stdout-path".
A change to the COFF zImage code to fix booting old powermacs.
A couple of minor build fixes.

Pull drm fixes from Dave Airlie:
"While I hoped things would calm down, the world hasn't joined with me,
but it's a few things scattered over a wide area. The i915 workarounds
regression fix is probably the largest, the rest are more usual sized.
We also get some new AMD PCI IDs.
There is also a patch in here to MAINTAINERS to added Daniel as an
official DRM toplevel co-maintainer, he's decided he wants to step up
and share the glory, and he'll likely process next weeks fixes while
I'm away on holidays.
Summary:
amdgpu:
- some new PCI IDs
- fixed firmware image updates
- power management fixes
- locking warning fix
nouveau:
- framebuffer flushing fix
- memory leak fix
- tegra device init regression fix
vmwgfx:
- OOM kernel memory fix
- excess return in function fix
i915:
- the biggest fix is a regression fix where workarounds weren't
getting reapplied after a gpu hang causing further crashing, this
fixes the workaround application to make it happen again
- GPU hang fixes for Braswell and some GEN3 GPUs
- GVT fix for broadwell tiling
rockchip:
- revert to fix a regression causing a WARN on shutdown

- avoid crash attaching to non-existant bridges"

With the new validation code, a malicious user-space app could
potentially submit command streams with enough buffer-object and resource
references in them to have the resulting allocated validion nodes and
relocations make the kernel run out of GFP_KERNEL memory.
Protect from this by having the validation code reserve TTM graphics
memory when allocating.

v2: Removed leftover debug printouts
to continue with operation that requires them.
- Fix bio-based DM core's dm_make_request() to properly impose device
limits on individual bios by making use of blk_queue_split().
- Fix long-standing race with how DM thinp notified userspace of
thin-pool mode state changes before they were actually made.
- Fix the zoned target's bio completion handling; this is a fairly
invassive fix at this stage but it is localized to the zoned target.
Any zoned target users will benefit from this fix.
