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.

The vdso patch series now has a temporary workaround, but I still want to
get this into v6.9 so we can place the hack with CONFIG_PAGE_SIZE
in the vdso.

I've applied this to the asm-generic tree already, please let me know if
there are still remaining issues. It's really close to the merge window
already, so I'd probably give this a few more days before I send a pull
request, or defer it to v6.10 if anything goes wrong.

Sorry for the delay, I was still waiting to resolve the m68k question,
but there were no further replies in the end, so I kept my original
version.

Changes from v1:

 - improve Kconfig help texts
 - remove an extraneous line in hexagon

Thanks Arnd, looks good to me.
