Pull power management fixes from Rafael Wysocki:
 "These fix two cpufreq issues, one in the core and one in the
  intel_pstate driver:

   - Fix CPU device node reference counting in the cpufreq core (Miquel
     Sabaté Solà)

   - Turn the spinlock used by the intel_pstate driver in hard IRQ
     context into a raw one to prevent the driver from crashing when
     PREEMPT_RT is enabled (Uwe Kleine-König)"

syzbot was able to trigger this warning [1], after injecting a
malicious packet through af_packet, setting skb-&gt;csum_start and thus
the transport header to an incorrect value.

We can at least make sure the transport header is after
the end of the network header (with a estimated minimal size).

syzbot was able to trigger this warning [1], after injecting a
malicious packet through af_packet, setting skb-&gt;csum_start and thus
the transport header to an incorrect value.

We can at least make sure the transport header is after
the end of the network header (with a estimated minimal size).

Pull generic unaligned.h cleanups from Al Viro:
 "Get rid of architecture-specific &lt;asm/unaligned.h&gt; includes, replacing
  them with a single generic &lt;linux/unaligned.h&gt; header file.

  It's the second largest (after asm/io.h) class of asm/* includes, and
  all but two architectures actually end up using exact same file.

  Massage the remaining two (arc and parisc) to do the same and just
  move the thing to from asm-generic/unaligned.h to linux/unaligned.h"

[ This is one of those things that we're better off doing outside the
  merge window, and would only cause extra conflict noise if it was in
  linux-next for the next release due to all the trivial #include line
  updates.  Rip off the band-aid.   - Linus ]

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

	sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i
