  workqueue: Fix NULL pointer dereference

Currently we are leaking addresses from the kernel to user space. This
script is an attempt to find some of those leakages. Script parses
`dmesg` output and /proc and /sys files for hex strings that look like
kernel addresses.

Only works for 64 bit kernels, the reason being that kernel addresses on
64 bit kernels have 'ffff' as the leading bit pattern making greping
possible. On 32 kernels we don't have this luxury.

Scripts is _slightly_ smarter than a straight grep, we check for false
positives (all 0's or all 1's, and vsyscall start/finish addresses).

[ I think there is a lot of room for improvement here, but it's already
  useful, so I'm merging it as-is. The whole "hash %p format" series is
  expected to go into 4.15, but will not fix %x users, and will not
  incentivize people to look at what they are leaking.     - Linus ]

There have been some cases where external tooling (e.g., kpatch-build)
creates a corrupt relocation which targets the wrong address.  This is a
silent failure which can corrupt memory in unexpected places.

On x86, the bytes of data being overwritten by relocations are always
initialized to zero beforehand.  Use that knowledge to add sanity checks
to detect such cases before they corrupt memory.

This fixes the following warning with GCC 4.6:

  mm/migrate.o: warning: objtool: migrate_misplaced_transhuge_page()+0x71: unreachable instruction

The problem is that the compiler merged identical annotate_unreachable()
inline asm blocks, resulting in a missing 'unreachable' annotation.

This problem happened before, and was partially fixed with:

  3d1e2360

 ("objtool: Prevent GCC from merging annotate_unreachable()")

That commit tried to ensure that each instance of the
annotate_unreachable() inline asm statement has a unique label.  It used
the __LINE__ macro to generate the label number.  However, even the line
number isn't necessarily unique when used in an inline function with
multiple callers (in this case, __alloc_pages_node()'s use of
VM_BUG_ON).

This reverts commit 43858b4f.

The reason I removed the leave_mm() calls in question is because the
heuristic wasn't needed after that patch.  With the original version
of my PCID series, we never flushed a "lazy cpu" (i.e. a CPU running
kernel thread) due a flush on the loaded mm.

Unfortunately, that caused architectural issues, so now I've
reinstated these flushes on non-PCID systems in:

    commit b956575b

 ("x86/mm: Flush more aggressively in lazy TLB mode").

That, in turn, gives us a power management and occasionally
performance regression as compared to old kernels: a process that
goes into a deep idle state on a given CPU and gets its mm flushed
due to activity on a different CPU will wake the idle CPU.

Reinstate the old ugly heuristic: if a CPU goes into ACPI C3 or an
intel_idle state that is likely to cause a TLB flush gets its mm
switched to init_mm before going idle.

FWIW, this heuristic is lousy.  Whether we should change CR3 before
idle isn't a good hint except insofar as the performance hit is a bit
lower if the TLB is getting flushed by the idle code anyway.  What we
really want to know is whether we anticipate being idle long enough
that the mm is likely to be flushed before we wake up.  This is more a
matter of the expected latency than the idle state that gets chosen.
This heuristic also completely fails on systems that don't know
whether the TLB will be flushed (e.g. AMD systems?).  OTOH it may be a
bit obsolete anyway -- PCID systems don't presently benefit from this
heuristic at all.

We also shouldn't do this callback from innermost bit of the idle code
due to the RCU nastiness it causes.  All the information need is
available before rcu_idle_enter() needs to happen.

Pull networking fixes from David Miller:
 "Hopefully this is the last batch of networking fixes for 4.14

  Fingers crossed...

   1) Fix stmmac to use the proper sized OF property read, from Bhadram
      Varka.

   2) Fix use after free in net scheduler tc action code, from Cong
      Wang.

   3) Fix SKB control block mangling in tcp_make_synack().

   4) Use proper locking in fib_dump_info(), from Florian Westphal.

   5) Fix IPG encodings in systemport driver, from Florian Fainelli.

   6) Fix division by zero in NV TCP congestion control module, from
      Konstantin Khlebnikov.

   7) Fix use after free in nf_reject_ipv4, from Tejaswi Tanikella"

  fib: fib_dump_info can no longer use __in_dev_get_rtnl
  stmmac: use of_property_read_u32 instead of read_u8
  net_sched: hold netns refcnt for each action
  net_sched: acquire RTNL in tc_action_net_exit()
  net: vrf: correct FRA_L3MDEV encode type

MIPS will soon not be a part of Imagination Technologies, and as such
many @imgtec.com email addresses will no longer be valid. This patch
updates the addresses for those who:

 - Have 10 or more patches in mainline authored using an @imgtec.com
   email address, or any patches dated within the past year.

 - Are still with Imagination but leaving as part of the MIPS business
   unit, as determined from an internal email address list.

 - Haven't already updated their email address (ie. JamesH) or expressed
   a desire to be excluded (ie. Maciej).

 - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt &
   myself.

New addresses are of the form firstname.lastname@mips.com, and all
verified against an internal email address list.  An entry is added to
.mailmap for each person such that get_maintainer.pl will report the new
addresses rather than @imgtec.com addresses which will soon be dead.

Instances of the affected addresses throughout the tree are then
mechanically replaced with the new @mips.com address.
