      arm64: dts: sdm845: add IPA iommus property · b94c280d
      Alex Elder authored 
      Add an "iommus" property to the IPA node in "sdm845.dtsi".  It is
required because there are two regions of memory the IPA accesses
through an SMMU.  The next few patches define and map those regions.

      Merge branch 'timer-add-fsleep-for-flexible-sleeping' · a88845d8

====================
timer: add fsleep for flexible sleeping

Sleeping for a certain amount of time requires use of different
functions, depending on the time period.
Documentation/timers/timers-howto.rst explains when to use which
function, and also checkpatch checks for some potentially
problematic cases.

So let's create a helper that automatically chooses the appropriate
sleep function -> fsleep(), for flexible sleeping
Not sure why such a helper doesn't exist yet, or where the pitfall is,
because it's a quite obvious idea.

If the delay is a constant, then the compiler should be able to ensure
that the new helper doesn't create overhead. If the delay is not
constant, then the new helper can save some code.

First user is the r8169 network driver. If nothing speaks against it,
then this series could go through the netdev tree.

      r8169: use fsleep in polling functions · d6836ef0
      Heiner Kallweit authored 
      Use new flexible sleep function fsleep() to merge the udelay and msleep
polling functions. We can safely do this because no polling function
is used in atomic context in this driver.

      ipv6: Implement draft-ietf-6man-rfc4941bis · 969c5464
      Fernando Gont authored 
      Implement the upcoming rev of RFC4941 (IPv6 temporary addresses):
https://tools.ietf.org/html/draft-ietf-6man-rfc4941bis-09

* Reduces the default Valid Lifetime to 2 days
  The number of extra addresses employed when Valid Lifetime was
  7 days exacerbated the stress caused on network
  elements/devices. Additionally, the motivation for temporary
  addresses is indeed privacy and reduced exposure. With a
  default Valid Lifetime of 7 days, an address that becomes
  revealed by active communication is reachable and exposed for
  one whole week. The only use case for a Valid Lifetime of 7
  days could be some application that is expecting to have long
  lived connections. But if you want to have a long lived
  connections, you shouldn't be using a temporary address in the
  first place. Additionally, in the era of mobile devices, general
  applications should nevertheless be prepared and robust to
  address changes (e.g. nodes swap wifi <-> 4G, etc.)

* Employs different IIDs for different prefixes
  To avoid network activity correlation among addresses configured
  for different prefixes

* Uses a simpler algorithm for IID generation
  No need to store "history" anywhere
