[GIT PULL] parisc architecture fixes for v4.14-rc2

[Helge Deller]

Hi Linus,

please pull fixes for the parisc architecture for kernel 4.14-rc2 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.14-2

Changelog:

- Unbreak parisc bootloader by avoiding a gcc-7 optimization to convert
  multiple byte-accesses into one word-access.

- Add missing HWPOISON page fault handler code. I completely missed that when I
  added HWPOISON support during this merge window and it only showed up now
  with the madvise07 LTP test case.

- Fix backtrace unwinding to stop when stack start has been reached.

- Issue warning if initrd has been loaded into memory regions with broken RAM
  modules.

- Fix HPMC handler (parisc hardware fault handler) to comply with architecture
  specification.

- Avoid compiler warnings about too large frame sizes.

- Minor init-section fixes.

Thanks,
Helge
