This is a series to switch powerpc VDSO to generic C implementation.
Changes in v13:
- Reorganised headers to avoid the need for a fake 32 bits config for building
VDSO32 on PPC64
- Rebased after the removal of powerpc 601
- Using DOTSYM() macro to call functions directly without using OPD
- Expl
For VDSO32 on PPC64, we create a fake 32 bits config, on the same
principle as MIPS architecture, in order to get the correct parts of
the different asm header files.
With the C VDSO, the performance is slightly lower, but it is worth
it as it will ease maintenance and evolution, and also brings c

64 bits version of __kernel_clock_gettime() which is

- Prepare the clocksource.h files to define VDSO_ARCH_CLOCKMODES
