gcc support for __builtin_bswap16() was supposedly added for powerpc in
gcc 4.6, and was then later added for other architectures in gcc 4.8.

However, Stephen Rothwell reported that attempting to use it on powerpc
in gcc 4.6 fails with:

  lib/vsprintf.c:160:2: error: initializer element is not constant
  lib/vsprintf.c:160:2: error: (near initialization for 'decpair[0]')
  lib/vsprintf.c:160:2: error: initializer element is not constant
  lib/vsprintf.c:160:2: error: (near initialization for 'decpair[1]')
  ...

I'm not entirely sure what those errors mean, but I don't see them on
gcc 4.8.  So let's consider gcc 4.8 to be the official starting point
for __builtin_bswap16().

Arnd Bergmann adds:
 "I found the commit in gcc-4.8 that replaced the powerpc-specific
  implementation of __builtin_bswap16 with an architecture-independent
  one.  Apparently the powerpc version (gcc-4.6 and 4.7) just mapped to
  the lhbrx/sthbrx instructions, so it ended up not being a constant,
  though the intent of the patch was mainly to add support for the
  builtin to x86:

    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52624

  has the patch that went into gcc-4.8 and more information."

net/mlx5e: Kconfig fixes for VxLAN

Reposting to net the build errors fixes posted by Arnd last week.

Originally Arnd posted those fixes to net-next, while the issue
is also seen in net.  For net-next a different approach is required
for fixing the issue as VXLAN and Device Drivers are no longer
dependent, but there is no harm for those fixes to get into net-next.

Optionally, once net is merged into net-next we can
Revert "net/mlx5e: make VXLAN support conditional" as the
CONFIG_MLX5_CORE_EN_VXLAN will no longer be required.

VXLAN can be disabled at compile-time or it can be a loadable
module while mlx5 is built-in, which leads to a link error:

drivers/net/built-in.o: In function `mlx5e_create_netdev':
ntb_netdev.c:(.text+0x106de4): undefined reference to `vxlan_get_rx_port'

This avoids the link error and makes the vxlan code optional,
like the other ethernet drivers do as well.

UDP tunnel segmentation code relies on the inner offsets being set for
an UDP tunnel GSO packet, but the inner *_complete() functions will
set the inner offsets only if 'encapsulation' is set before calling
them.  Currently, udp_gro_complete() sets 'encapsulation' only after
the inner *_complete() functions are done.  This causes the inner
offsets having invalid values after udp_gro_complete() returns, which
in turn will make it impossible to properly segment the packet in case
it needs to be forwarded, which would be visible to the user either as
invalid packets being sent or as packet loss.

This patch fixes this by setting skb's 'encapsulation' in
udp_gro_complete() before calling into the inner complete functions,
and by making each possible UDP tunnel gro_complete() callback set the
inner_mac_header to the beginning of the tunnel payload.

qede requires qed to provide enough resources to accommodate 16 combined
channels, but that upper-bound isn't actually being enforced by it.
Instead, qed inform back to qede how many channels can be opened based on
available resources - but that calculation doesn't really take into account
the resources requested by qede; Instead it considers other FW/HW available
resources.

As a result, if a user would increase the number of channels to more than
16 [e.g., using ethtool] the chip would hang.

This change increments the resources requested by qede to 64 combined
channels instead of 16; This value is an upper bound on the possible
available channels [due to other FW/HW resources].

  sti-cpufreq, ARM64 cpuidle, Operating Performance Points framework,
  generic device properties framework) and one fix for a hotplug-related
  deadlock in ACPICA that's been there forever, but is nasty enough.

  Specifics:

   - Fix for a recent regression in the intel_pstate driver causing it
     to fail to restore the HWP (HW-managed P-states) configuration of
     the boot CPU after suspend-to-RAM (Rafael Wysocki).

   - Fix for two recent regressions in the intel_pstate driver, one that
     can trigger a divide by zero if the driver is accessed via sysfs
     before it manages to take the first sample and one causing it to
     fail to update a structure field used in a trace point, so the
     information coming from it is less useful (Rafael Wysocki).

   - Fix for a problem in the sti-cpufreq driver introduced during the
     4.5 cycle that causes it to break CPU PM in multi-platform kernels
     by registering cpufreq-dt (which subsequently doesn't work)
     unconditionally and preventing the driver that would actually work
     from registering (Sudeep Holla).

   - Stable-candidate fix for an ARM64 cpuidle issue causing idle state
     usage counters to be incorrectly updated for idle states that were
     not entered due to errors (James Morse).

   - Fix for a recently introduced issue in the OPP (Operating
     Performance Points) framework causing it to print bogus error
     messages for missing optional regulators (Viresh Kumar).

   - Fix for a recently introduced issue in the generic device
     properties framework that may cause it to attempt to dereferece and
     invalid pointer in some cases (Heikki Krogerus).

With the newly introduced helper functions the skb pulling is hidden
in the checksumming function - and undone before returning to the
caller.

The IGMP and MLD query parsing functions in the bridge still
assumed that the skb is pointing to the beginning of the IGMP/MLD
message while it is now kept at the beginning of the IPv4/6 header.

If there is a querier somewhere else, then this either causes
the multicast snooping to stay disabled even though it could be
enabled. Or, if we have the querier enabled too, then this can
create unnecessary IGMP / MLD query messages on the link.

Fixing this by taking the offset between IP and IGMP/MLD header into
account, too.
