Less code means less bugs so add a knob to skip the compat stuff.

This is tested on ppc64le top of

https://patchwork.ozlabs.org/patch/1153850/
https://patchwork.ozlabs.org/patch/1158412/

Changes in v2: saner CONFIG_COMPAT ifdefs
Changes in v3:
 - change llseek to 32bit instead of builing it unconditionally in fs
 - clanup the makefile conditionals
 - remove some ifdefs or convert to IS_DEFINED where possible
Changes in v4:
 - cleanup is_32bit_task and current_is_64bit
 - more makefile cleanup
Changes in v5:
 - more current_is_64bit cleanup
 - split off callchain.c 32bit and 64bit parts
Changes in v6:
 - cleanup makefile after split
 - consolidate read_user_stack_32
 - fix some checkpatch warnings
Changes in v7:
 - add back __ARCH_WANT_SYS_LLSEEK to fix build with llseek
 - remove leftover hunk
 - add review tags
Changes in v8:
 - consolidate valid_user_sp to fix it in the split callchain.c
 - fix build errors/warnings with PPC64 !COMPAT and PPC32
Changes in v9:
 - remove current_is_64bit()

Michal Suchanek (8):

    default.
  powerpc/perf: split callchain.c by bitness
