Subject: [patch V2 00/17] VDSO consolidation

This is the second version of the VDSO consolidation series. The first
version can be found here:

   https://lore.kernel.org/lkml/r/20200114185237.273005683@linutronix.de

The changes since V1:

    - Tiny optimization of x86/TSC (new)

    - Address review comments from V1 (bisectability, spelling ...)

    - Include the preparatory patches from Christophe which allow powerpc
      to be switched over.

This conflicts slightly with the ARM64 time namespace patch series, but
that's trivial to fix up.

Thanks,

	tglx
