3a6ab5c7dc scripts/spdxcheck.py: always open files in binary mode
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).

f1733a1d3c checkstack.pl: fix for aarch64
There is actually a space after "sp," like this,

    ffff2000080813c8:       a9bb7bfd        stp     x29, x30, [sp, #-80]!

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.

61c6de6672 fs/iomap.c: get/put the page in iomap_page_create/release()
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.

8ace22bce8 hugetlbfs: call VM_BUG_ON_PAGE earlier in free_huge_page()
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.

9def36e0fa mm/sparse: add common helper to mark all memblocks present
Presently the arches arm64, arm and sh have a function which loops
through each memblock and calls memory present.  riscv will require a
similar function.

Introduce a common memblocks_present() function that can be used by all
the arches.  Subsequent patches will cleanup the arches that make use of
this.

d1402fc708 mm: introduce common STRUCT_PAGE_MAX_SHIFT define
This define is used by arm64 to calculate the size of the vmemmap
region.  It is defined as the log2 of the upper bound on the size of a
struct page.

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.

5b5260902a alpha: fix hang caused by the bootmem removal
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.

4645453cef powerpc fixes for 4.20 #4
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.

Merge tag 'powerpc-4.20-4' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:
 "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.

  Thanks to: Benjamin Herrenschmidt, Daniel Axtens, Dmitry V. Levin,
  Elvira Khabirova, Oliver O'Halloran, Paul Mackerras, Radu Rendec, Rob
  Herring, Sandipan Das"

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

  mediatek:

   - avoid crash attaching to non-existant bridges"

fd56746775 drm/vmwgfx: Protect from excessive execbuf kernel memory allocations v3
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.

28adac6f74 MAINTAINERS: Daniel for drm co-maintainer
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.

37fbd834b4 IB/core: Fix oops in netdev_next_upper_dev_rcu()
When support for bonding of RoCE devices was added, there was
necessarily a link between the RoCE device and the paired netdevice that
was part of the bond.  If you remove the mlx4_en module, that paired
association is broken (the RoCE device is still present but the paired
netdevice has been released).  We need to account for this in
is_upper_ndev_bond_master_filter() and filter out those links with a
broken pairing or else we later oops in netdev_next_upper_dev_rcu().

5b2e31201c drm/i915: Flush GPU relocs harder for gen3
Adding an extra MI_STORE_DWORD_IMM to the gpu relocation path for gen3
was good, but still not good enough. To survive 24+ hours under test we
needed to perform not one, not two but three extra store-dw. Doing so
for each GPU relocation was a little unsightly and since we need to
worry about userspace hitting the same issues, we should apply the dummy
store-dw into the EMIT_FLUSH.

fe78742d7f drm/i915: Allocate a common scratch page
Currently we allocate a scratch page for each engine, but since we only
ever write into it for post-sync operations, it is not exposed to
userspace nor do we care for coherency. As we then do not care about its
contents, we can use one page for all, reducing our allocations and
avoid complications by not assuming per-engine isolation.

For later use, it simplifies engine initialisation (by removing the
allocation that required struct_mutex!) and means that we can always rely
on there being a scratch page.

cf66b8a0ba drm/i915/execlists: Apply a full mb before execution for Braswell
Braswell is really picky about having our writes posted to memory before
we execute or else the GPU may see stale values. A wmb() is insufficient
as it only ensures the writes are visible to other cores, we need a full
mb() to ensure the writes are in memory and visible to the GPU.

The most frequent failure in flushing before execution is that we see
stale PTE values and execute the wrong pages.

24199c5436 drm/nouveau/kms: Fix memory leak in nv50_mstm_del()
Noticed this while working on redoing the reference counting scheme in
the DP MST helpers. Nouveau doesn't attempt to call
drm_dp_mst_topology_mgr_destroy() at all, which leaves it leaking all of
the resources for drm_dp_mst_topology_mgr and it's children mstbs+ports.

Fixes: f479c0ba4a ("drm/nouveau/kms/nv50: initial support for DP 1.2 multi-stream")
