[GIT PULL] parisc architecture fixes for kernel v5.2-rc4

[Helge Deller]

Hi Linus,

please pull some additional fixes and cleanups for the parisc architecture from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-5.2-3

Changes include
- Fix crashes when accessing PCI devices on some machines like C240 and J5000.
  The crashes were triggered because we replaced cache flushes by nops in the
  alternative coding where we shouldn't for some machines.
- Dave fixed a race in the usage of the sr1 space register when used to
  load the coherence index.
- Use the hardware lpa instruction to to load the physical address of kernel
  virtual addresses in the iommu driver code.
- The kernel may fail to link when CONFIG_MLONGCALLS isn't set. Solve that by
  rearranging functions in the final vmlinux executeable.
- Some defconfig cleanups and removal of compiler warnings.

Thanks,
Helge
