[PATCH 0/4] arch: mm, vdso: consolidate PAGE_SIZE definition

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

Naresh noticed that the newly added usage of the PAGE_SIZE macro in
include/vdso/datapage.h introduced a build regression. I had an older
patch that I revived to have this defined through Kconfig rather than
through including asm/page.h, which is not allowed in vdso code.

I rebased and tested on top of the tip/timers/core branch that
introduced the regression. If these patches get added, the
compat VDSOs all build again, but the changes are a bit invasive.

  arch: consolidate existing CONFIG_PAGE_SIZE_*KB definitions
  arch: simplify architecture specific page size configuration
  arch: define CONFIG_PAGE_SIZE_*KB on all architectures
  vdso: avoid including asm/page.h
