On our AT91SAM9260 board we use the same sdio bus for wifi and for the
sd card slot. This caused the atmel-mci to give the following splat on
the serial console:

 "11 fixes"

* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
  scripts/spdxcheck.py: always open files in binary mode
  checkstack.pl: fix for aarch64
  userfaultfd: check VM_MAYWRITE was set after verifying the uffd is registered
  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).

There is actually a space after "sp," like this,

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
function's objdump, and is then able to calculate each function's stack
correctly.

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 82cb1417
("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.

A stack trace was triggered by VM_BUG_ON_PAGE(page_mapcount(page), page)
in free_huge_page().  Unfortunately, the page->mapping field was set to
NULL before this test.  This made it more difficult to determine the
root cause of the problem.

Move the VM_BUG_ON_PAGE tests earlier in the function so that if they do
trigger more information is present in the page struct.

Most architectures provide prototypes for the PCI I/O mapping operations
when asm/io.h is included but SH doesn't currently do that, leading to
for example warnings in sound/pci/hda/patch_ca0132.c when pci_iomap() is
used on current -next.  Make SH more consistent with other architectures
by including asm-generic/pci_iomap.h in asm/io.h.

region.  It is defined as the log2 of the upper bound on the size of a

We move it into mm_types.h so it can be defined properly instead of set
and checked with a build bug.  This also allows us to use the same
define for riscv.

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.

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.

Merge tag 'for-4.20/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm

Pull device mapper fixes from Mike Snitzer:

 - Fix DM cache metadata to verify that a cache has block before trying
   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.

lkml and Linus gained a CoC, and it's serious this time. Which means
my no 1 reason for declining to officially step up as drm maintainer
is gone, and I didn't find any new good excuse.

I chatted with a few people in private already, and the biggest
concern is that I mislay my community hat and start running around
with my intel hat only. Or some other convenient abuse of trust.

That's why this patch doesn't just need a lot of acks that mean "yeah
seems fine to me", but a lot of acks that mean "yeah we'll tell you
when you're over the line and usurp you from that comfy chair if you
don't get it". Which I think we've been done a fairly good job here at
dri-devel in general, but better to be clear.

Rough idea is that I'll do this for maybe 2-3 years, helping Dave
figure out a group model for drm overall. And getting the tooling and
infrastructure for that off the ground. Then step down again because
some other shiny thing that needs chasing. Of course as plans tend to
do, this one will probably pan out a bit different in reality.
