All architectures currently explicitly define their page size. In some
cases (ppc, parisc, ia64, sparc64) this size is somewhat configurable.
There several reimplementations of ways to make sure that PAGE_SIZE
is usable in assembly code, yet still somewhat type safe for use in
C code (as a UL type). These are all very similar. There are also a
number of macros based off of PAGE_SIZE/SHIFT which are duplicated
across architectures.
This patch unifies all of those definitions. It defines PAGE_SIZE in
a single header which gets its definitions from Kconfig. The new
Kconfig options mirror what used to be done with #ifdefs and
arch-specific Kconfig options. The new Kconfig menu eliminates
the need for parisc, ia64, and sparc64 to have their own "choice"
menus for selecting page size. The help text has been adapted from
these three architectures, but is now more generic.
This survives cross-compilation on arm, i386, x86_64, sparc64 and
ia64.
