Subject: [GIT PULL] parisc architecture updates for v4.9-rc1

Hi Linus,

please pull the updates for 4.9-rc1 for the parisc architecture from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.9-1

Changes include:
 
- Fix boot of 32bit SMP kernel (initial kernel mapping was too small)

- Added hardened usercopy checks

- Drop bootmem and switch to memblock and NO_BOOTMEM implementation

- Drop the BROKEN_RODATA config option (and thus remove the relevant code from
  the generic headers and files because parisc was the last architecture which
  used this config option)

- Improve segfault reporting by printing human readable error strings

- Various smaller changes, e.g. dwarf debug support for assembly code, update
  comments regarding copy_user_page_asm, switch to kmalloc_array()

Thanks,
Helge
