Pull parisc architecture fixes from Helge Deller:
 "Some small parisc architecture fixes for 6.0-rc6:

  One patch lightens up a previous commit and thus unbreaks building the
  debian kernel, which tries to configure a 64-bit kernel with the
  ARCH=parisc environment variable set.

  The other patches fixes asm/errno.h includes in the tools directory
  and cleans up memory allocation in the iosapic driver.

  Summary:

   - Allow configuring 64-bit kernel with ARCH=parisc

   - Fix asm/errno.h includes in tools directory for parisc and xtensa

   - Clean up iosapic memory allocation

   - Minor typo and spelling fixes"

Enabling this option will probably slow down your kernel.

help
Enable this if you want to support 64bit kernel on PA-RISC platform.
At the moment, only people willing to use more than 2GB of RAM,
or having a 64bit-only capable PA-RISC machine should say Y here.
Since there is no 64bit userland on PA-RISC, there is no point to
enable this option otherwise. The 64bit kernel is significantly bigger
and slower than the 32bit one.
