Fix UV call into kgdb to depend only on whether KGDB is defined
and not both KGDB and KDB.  This allows the power nmi command to
use the gdb remote connection if enabled.  Note new action of
'kgdb' needs to be set as well to indicate user wants to wait
for gdb to be connected.  If it's set to 'kdb' then an error
message is displayed if KDB is not configured.

Also note that if both KGDB and KDB are enabled, then the action
of 'kgdb' or 'kdb' has no affect on which is used.  See the KGDB
documentation for further information.

Some code added to the debug_core module had KDB dependencies
that it shouldn't have.  Move the KDB dependent REASON back to
the caller to remove the dependency in the debug core code.

Update the call from the UV NMI handler to conform to the new
interface.

A couple of years ago all the "L: lkml" email list entries in
MAINTAINERS were removed and replaced with a 'the rest' entry
at the end of the file - under the theory that this is unnecessary
duplication and that people would find it intuitive:

  b5472cdd MAINTAINERS: remove L: linux-kernel@vger.kernel.org from all but "THE REST"

So it turns out that it's all but intuitive, not all people
use scripts/get_maintainer.pl to extract maintainer contact info,
some people read the MAINTAINERS file and see the lack of 'L:' entries
of various lkml-only subsystems and are sending patches to the
maintainers only, without Cc:-ing lkml.  They arguably have a point.

In hindsight removing all the "L: lkml" entries was probably not
an overly good idea, not all mechanic duplication should be eliminated:
in files read by humans it's useful to have 'at a glance' summary for
all email addresses important to a subsystem's maintenance, in a single
place, without too many imported rules and assumptions.

So, to make the lkml fallback really apparent, add back 'L: lkml'
entries to all subsystem entries whose workflow I'm involved in.
This should at minimum be a per subsystem policy thing.

 "This includes the basic infrastructure for MPX (Memory Protection
  Extensions) support, but does not include MPX support itself.  It is,
  however, a prerequisite for KVM support for MPX, which I believe will
  be pushed later this merge window by the KVM team.

  This includes moving the functionality in
  futex_atomic_cmpxchg_inatomic() into a new function in uaccess.h so it
  can be reused - this will be used by the final MPX patches.

  The actual MPX functionality (map management and so on) will be pushed

     - Add shell completion support (Ramkumar Ramachandra)
     - Add '-v' option (Dongsheng Yang)
     - Support --guestmount (Dongsheng Yang)

       at probe time and other 'perf probe' operations that use DWARF
       information.

       This supports only binaries with debugging information at this
       time, detached debuginfo (aka debuginfo packages) support should
       come in later patches (Masami Hiramatsu)

   - 'perf record':
     - Rename --no-delay option to --no-buffering, better reflecting its
       purpose and freeing up '--delay' to take the place of
       '--initial-delay', so that 'record' and 'stat' are consistent
       (Arnaldo Carvalho de Melo)
     - Default the -t/--thread option to no inheritance (Adrian Hunter)
     - Make per-cpu mmaps the default (Adrian Hunter)

       --header option in the stdio UI (Namhyung Kim)

   - 'perf script':
     - Add an option in 'perf script' to print the source line number
       (Adrian Hunter)
     - Add --header/--header-only options to 'script' and 'report', the
       default is not tho show the header info, but as this has been the
       default for some time, leave a single line explaining how to
       obtain that information (Jiri Olsa)
     - Add options to show comm, fork, exit and mmap PERF_RECORD_ events
       (Namhyung Kim)

   - 'perf top':
     - Make 'perf top -g' refer to callchains, for consistency with
       other tools (David Ahern)

     - Handle old kernels where the "raw_syscalls" tracepoints were
       called plain "syscalls" (David Ahern)
     - Remove thread summary coloring, by Pekka Enberg.
     - Honour -m option in 'trace', the tool was offering the option to
       set the mmap size, but wasn't using it when doing the actual mmap
       on the events file descriptors (Jiri Olsa)

   - generic:
     - Backport libtraceevent plugin support (trace-cmd repository, with
       plugins for jbd2, hrtimer, kmem, kvm, mac80211, sched_switch,
       function, xen, scsi, cfg80211 (Jiri Olsa)
     - Print session information only if --stdio is given (Namhyung Kim)

  Tooling side changes, developer visible (plumbing):

   - Improve 'perf probe' exit path, release resources (Masami
     Hiramatsu)
   - Improve libtraceevent plugins exit path, allowing the registering
     of an unregister handler to be called at exit time (Namhyung Kim)
   - Add an alias to the build test makefile (make -C tools/perf
     build-test) (Namhyung Kim)
   - Get rid of die() and friends (good riddance!) in libtraceevent
     (Namhyung Kim)
   - Fix cross build problems related to pkgconfig and CROSS_COMPILE not
     being propagated to the feature tests, leading to features being
     tested in the host and then being enabled on the target (Mark
     Rutland)
   - Improve forked workload error reporting by sending the errno in the
     signal data queueing integer field, using sigqueue and by doing the
     signal setup in the evlist methods, removing open coded equivalents
     in various tools (Arnaldo Carvalho de Melo)
   - Do more auto exit cleanup chores in the 'evlist' destructor, so
     that the tools don't have to all do that sequence (Arnaldo Carvalho
     de Melo)
   - Pack 'struct perf_session_env' and 'struct trace' (Arnaldo Carvalho
     de Melo)

     'inject' (Jiri Olsa)
   - Use pr_*() functions where applicable in 'report' (Namhyumg Kim)
   - Add 'machine' 'addr_location' struct to have full picture (machine,
     thread, map, symbol, addr) for a (partially) resolved address,
     reducing function signatures (Arnaldo Carvalho de Melo)
   - Reduce code duplication in the histogram entry creation/insertion
     (Arnaldo Carvalho de Melo)
   - Auto allocate annotation histogram data structures (Arnaldo
     Carvalho de Melo)

     memory in struct pointers to NULL, to help fixing use after free
     bugs (Arnaldo Carvalho de Melo)
   - Rename some struct DSO binary_type related members and methods, to
     clarify its purpose and need for differentiation (symtab_type, ie
     one is about the files .text, CFI, etc, i.e.  its binary contents,
     and the other is about where the symbol table came from (Arnaldo
     Carvalho de Melo)
   - Convert to new topic libraries, starting with an API one (sysfs,

Pull strong stackprotector support from Ingo Molnar:
 "This tree adds a CONFIG_CC_STACKPROTECTOR_STRONG=y, a new, stronger
  stack canary checking method supported by the newest GCC versions (4.9
  and later).

  Here's the 'intensity comparison' between the various protection
  modes:

      - defconfig
        11430641 kernel text size
        36110 function bodies

      - defconfig + CONFIG_CC_STACKPROTECTOR_REGULAR
        11468490 kernel text size (+0.33%)
        1015 of 36110 functions are stack-protected (2.81%)

      - defconfig + CONFIG_CC_STACKPROTECTOR_STRONG via this patch
        11692790 kernel text size (+2.24%)
        7401 of 36110 functions are stack-protected (20.5%)

  the strong model comes with non-trivial costs, which is why we
  preserved the 'regular' and 'none' models as well"

Pull core debug changes from Ingo Molnar:
 "Currently there are two methods to set the panic_timeout: via
  'panic=X' boot commandline option, or via /proc/sys/kernel/panic.

  This tree adds a third panic_timeout configuration method:
  configuration via Kconfig, via CONFIG_PANIC_TIMEOUT=X - useful to
  distros that generally want their kernel defaults to come with the
  .config.

  CONFIG_PANIC_TIMEOUT defaults to 0, which was the previous default
  value of panic_timeout.

  Doing that unearthed a few arch trickeries regarding arch-special
  panic_timeout values and related complications - hopefully all
  resolved to the satisfaction of everyone"

Pull localmodconfig update from Steven Rostedt:
 "While debugging the problem with localmodconfig and the ALSA codec
  modules all being set, I discovered a small bug in the dependency
  logic.

  If a config has a dependency based on its setting value,
  localmodcondig misses it.

  For example:

    config FOO
        default y if BAR || ZOO

  If FOO is needed for a module and is set to '=m', and so are BAR or
  ZOO, localmodconfig will not see that BAR or ZOO are also needed for
  the foo module, and will incorrectly disable them"

NULL, since it's still being called from the constructor.  Instead, pass
