Subject: [GIT PULL] parisc architecture fixes for 4.14

Hi Linus,

please pull three small but important fixes for the parisc architecture for kernel 4.14 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.14-3

Three small important fixes for the parisc architecture:

- Export __cmpxchg_u64() symbol on 32bit kernel too. This unbreaks building the
  kernel with ixgbe kernel module. From Guenter Roeck.

- Fix 64-bit atomic cmpxchg kernel helper function for 32-bit kernel in LWS
  code for userspace. This unbreaks e.g. the 64-bit variant of the glibc
  function __sync_fetch_and_add() with a 32-bit parisc kernel. From John
  David Anglin, tagged for backport to v3.13+.

- Detect nonsynchronous CPU-internal cr16 cycle counters more reliable. This
  avoids stalled CPU warnings by the kernel soft lockup detector. From me,
  tagged for backport to v4.13+.

Thanks,
Helge
