1dbdcc8109 selftests: watchdog: accept multiple params on command line
Watchdog drivers are not required to retain programming information,
such as timeouts, after the watchdog device is closed.  Therefore,
the watchdog test should be able to perform multiple actions after
opening the watchdog device.

For example, to set the timeout to 10s and ping every 5s:

	watchdog-test -t 10 -p 5 -e

Also, display the periodic decimal point only if the keep-alive call
succeeds.

70d1a4e668 selftests/vm: Set mmap()'s fd as -1 for MAP_ANONYMOUS flag
Man page of mmap() says that portable applications should ensure fd
argument to be -1 if MAP_ANONYMOUS flag is set as below:
```
The  mapping is not backed by any file; its contents are initialized to
zero.  The fd and offset arguments are ignored; however, some
implementations require  fd  to be  -1  if  MAP_ANONYMOUS  (or
MAP_ANON)  is specified, and portable applications
should ensure this.
```

However, few mmap() calls under selftests/vm/ uses 0 as fd though they
use MAP_ANONYMOUS flag.  This commit changes the argument to be -1 as
recommended.

Fix to compare a zero-filled hexadecimal value with a part of
string of long hexadecimal value.

In check_types(), the last part of testcase compares with
the hex value formatted by "%x" with a part of a string of
long hex value (trimmed by tail -c and head -c). However,
if that part of long hex value contains zero (e.g. "05" of
"a3082059"), printf generated value (e.g. "5") is diffrent
string, and the test case failed.

To fix this, pass "%02x" instead of "%x" to printf.

cf393195c3 Merge branch 'idr-4.11' of git://git.infradead.org/users/willy/linux-dax
Pull IDR rewrite from Matthew Wilcox:
 "The most significant part of the following is the patch to rewrite the
  IDR & IDA to be clients of the radix tree. But there's much more,
  including an enhancement of the IDA to be significantly more space
  efficient, an IDR & IDA test suite, some improvements to the IDR API
  (and driver changes to take advantage of those improvements), several
  improvements to the radix tree test suite and RCU annotations.

  The IDR & IDA rewrite had a good spin in linux-next and Andrew's tree
  for most of the last cycle. Coupled with the IDR test suite, I feel
  pretty confident that any remaining bugs are quite hard to hit. 0-day
  did a great job of watching my git tree and pointing out problems; as
  it hit them, I added new test-cases to be sure not to be caught the
  same way twice"

Willy goes on to expand a bit on the IDR rewrite rationale:
 "The radix tree and the IDR use very similar data structures.

  Merging the two codebases lets us share the memory allocation pools,
  and results in a net deletion of 500 lines of code. It also opens up
  the possibility of exposing more of the features of the radix tree to
  users of the IDR (and I have some interesting patches along those
  lines waiting for 4.12)

  It also shrinks the size of the 'struct idr' from 40 bytes to 24 which
  will shrink a fair few data structures that embed an IDR"

d811914d87 userfaultfd: non-cooperative: rename *EVENT_MADVDONTNEED to *EVENT_REMOVE
Patch series "userfaultfd: non-cooperative: add madvise() event for
MADV_REMOVE request".

These patches add notification of madvise(MADV_REMOVE) event to
non-cooperative userfaultfd monitor.

The first pacth renames EVENT_MADVDONTNEED to EVENT_REMOVE along with
relevant functions and structures.  Using _REMOVE instead of
_MADVDONTNEED describes the event semantics more clearly and I hope it's
not too late for such change in the ABI.

This patch (of 3):

The UFFD_EVENT_MADVDONTNEED purpose is to notify uffd monitor about
removal of certain range from address space tracked by userfaultfd.
Hence, UFFD_EVENT_REMOVE seems to better reflect the operation
semantics.  Respectively, 'madv_dn' field of uffd_msg is renamed to
'remove' and the madvise_userfault_dontneed callback is renamed to
userfaultfd_remove.

Merge tag 'drm-for-v4.11-less-shouty' of git://people.freedesktop.org/~airlied/linux

Pull drm updates from Dave Airlie:
 "This is the main drm pull request for v4.11.

  Nothing too major, the tinydrm and mmu-less support should make
  writing smaller drivers easier for some of the simpler platforms, and
  there are a bunch of documentation updates.

  Intel grew displayport MST audio support which is hopefully useful to
  people, and FBC is on by default for GEN9+ (so people know where to
  look for regressions). AMDGPU has a lot of fixes that would like new
  firmware files installed for some GPUs.

  Other than that it's pretty scattered all over.

  I may have a follow up pull request as I know BenH has a bunch of AST
  rework and fixes and I'd like to get those in once they've been tested
  by AST, and I've got at least one pull request I'm just trying to get
  the author to fix up.

9903bd7b73 userfaultfd: hugetlbfs: add userfaultfd_hugetlb test
Test userfaultfd hugetlb functionality by using the existing testing
method (in userfaultfd.c).  Instead of an anonymous memeory, a hugetlbfs
file is mmap'ed private.  In this way fallocate hole punch can be used
to release pages.  This is because madvise(MADV_DONTNEED) is not
supported for huge pages.

Use the same file, but create wrappers for allocating ranges and
releasing pages.  Compile userfaultfd.c with HUGETLB_TEST defined to
produce an executable to test userfaultfd hugetlb functionality.

b2064617c7 driver core patches for 4.11-rc1
Here is the "small" driver core patches for 4.11-rc1.
 
 Not much here, some firmware documentation and self-test updates, a
 debugfs code formatting issue, and a new feature for call_usermodehelper
 to make it more robust on systems that want to lock it down in a more
 secure way.
 
 All of these have been linux-next for a while now with no reported
 issues.
