ARM: dts: explicitly mark skeleton.dtsi as deprecated
As noted in commit
3ebee5a2e141496b ("arm64: dts: kill skeleton.dtsi"),
there are a number of problems with skeleton.dtsi, and it would be
prefereable to remove it entirely. As there are a large number of
existing users, fixing these up will take a while.
This patch adds a note to arm's skeleton.dtsi noting that this is the
case, to make this more obvious and hopefully minimize new uptake of
skeleton.dtsi in the mean time.

ARM: dts: keystone: specify usb mode explicitly
The USB OTG mode is not supported by Kestone 2 devices, as result, the
USB devices enumeration and detection will not work properly when
kernel is built with CONFIG_USB_DWC3_DUAL_ROLE=y (default for multi
platform build):
- it's required to load gadget drivers manually to make host mode
work and this confuses current Keystone 2 users
- device mode is not working, because port can't detect and switch to
peripheral/host mode dynamically.
Hence, specify usb mode explicitly in DT: usb0 = "host" for all KS2
devices and usb1 = "peripheral" for K2E.

drm/atomic: Don't potentially reset color_mgmt_changed on successive property updates.
Due to assigning the 'replaced' value instead of or'ing it,
if drm_atomic_crtc_set_property() gets called multiple times,
the last call will define the color_mgmt_changed flag, so
a non-updating call to a property can reset the flag and
prevent actual hw state updates required by preceding
property updates.

mm: silently skip readahead for DAX inodes
For DAX inodes we need to be careful to never have page cache pages in
the mapping->page_tree. This radix tree should be composed only of DAX
exceptional entries and zero pages.
ltp's readahead02 test was triggering a warning because we were trying
to insert a DAX exceptional entry but found that a page cache page had
already been inserted into the tree. This page was being inserted into
the radix tree in response to a readahead(2) call.
Readahead doesn't make sense for DAX inodes, but we don't want it to
report a failure either. Instead, we just return success and don't do
any work.

fs/seq_file: fix out-of-bounds read
seq_read() is a nasty piece of work, not to mention buggy.
It has (I think) an old bug which allows unprivileged userspace to read
beyond the end of m->buf.
I was getting these:

Disabling lock debugging due to kernel taint
This seems to be the same thing that Dave Jones was seeing here:
https://lkml.org/lkml/2016/8/12/334
There are multiple issues here:
1) If we enter the function with a non-empty buffer, there is an attempt
to flush it. But it was not clearing m->from after doing so, which
means that if we try to do this flush twice in a row without any call
to traverse() in between, we are going to be reading from the wrong
place -- the splat above, fixed by this patch.
2) If there's a short write to userspace because of page faults, the
buffer may already contain multiple lines (i.e. pos has advanced by
more than 1), but we don't save the progress that was made so the
next call will output what we've already returned previously. Since
that is a much less serious issue (and I have a headache after
staring at seq_read() for the past 8 hours), I'll leave that for now.

A bugfix in v4.8-rc2 introduced a harmless warning when

mm: clarify COMPACTION Kconfig text
The current wording of the COMPACTION Kconfig help text doesn't
emphasise that disabling COMPACTION might cripple the page allocator
which relies on the compaction quite heavily for high order requests and
an unexpected OOM can happen with the lack of compaction. Make sure we
are vocal about that.

Commit
bbeddf52adc1 ("printk: move braille console support into separate

_braille_console_setup(), changing the type of variable str from char*

Update the code to make "brl=" option work again and replace memcmp()

soft_dirty: fix soft_dirty during THP split
While adding proper userfaultfd_wp support with bits in pagetable and
swap entry to avoid false positives WP userfaults through swap/fork/
KSM/etc, I've been adding a framework that mostly mirrors soft dirty.
So I noticed in one place I had to add uffd_wp support to the pagetables
that wasn't covered by soft_dirty and I think it should have.
Example: in the THP migration code migrate_misplaced_transhuge_page()
pmd_mkdirty is called unconditionally after mk_huge_pmd.
entry = mk_huge_pmd(new_page, vma->vm_page_prot);
entry = maybe_pmd_mkwrite(pmd_mkdirty(entry), vma);
That sets soft dirty too (it's a false positive for soft dirty, the soft
dirty bit could be more finegrained and transfer the bit like uffd_wp
will do.. pmd/pte_uffd_wp() enforces the invariant that when it's set
pmd/pte_write is not set).
However in the THP split there's no unconditional pmd_mkdirty after
mk_huge_pmd and pte_swp_mksoft_dirty isn't called after the migration
entry is created. The code sets the dirty bit in the struct page
instead of setting it in the pagetable (which is fully equivalent as far
as the real dirty bit is concerned, as the whole point of pagetable bits
is to be eventually flushed out of to the page, but that is not
equivalent for the soft-dirty bit that gets lost in translation).
This was found by code review only and totally untested as I'm working
to actually replace soft dirty and I don't have time to test potential
soft dirty bugfixes as well :).
Transfer the soft_dirty from pmd to pte during THP splits.
This fix avoids losing the soft_dirty bit and avoids userland memory
corruption in the checkpoint.

sysctl: handle error writing UINT_MAX to u32 fields
We have scripts which write to certain fields on 3.18 kernels but this
seems to be failing on 4.4 kernels. An entry which we write to here is
xfrm_aevent_rseqth which is u32.
echo
4294967295 > /proc/sys/net/core/xfrm_aevent_rseqth
Commit
230633d109e3 ("kernel/sysctl.c: detect overflows when converting
to int") prevented writing to sysctl entries when integer overflow
occurs. However, this does not apply to unsigned integers.
Heinrich suggested that we introduce a new option to handle 64 bit
limits and set min as 0 and max as UINT_MAX. This might not work as it
leads to issues similar to __do_proc_doulongvec_minmax. Alternatively,
we would need to change the datatype of the entry to 64 bit.
static int __do_proc_doulongvec_minmax(void *data, struct ctl_table
{
i = (unsigned long *) data; //This cast is causing to read beyond the size of data (u32)
vleft = table->maxlen / sizeof(unsigned long); //vleft is 0 because maxlen is sizeof(u32) which is lesser than sizeof(unsigned long) on x86_64.
Introduce a new proc handler proc_douintvec. Individual proc entries
will need to be updated to use the new handler.
