the very latest linux-headers package no longer installs asm/page.h ... this
will (and is) causing trouble for many packages
no, the answer is not any of the following:
- start installing asm/page.h again
- screw with /usr/src/linux/include/asm/page.h
- patch asm/page.h internally
the solution here is quite simple:
- dont include asm/page.h
- dont use the PAGE_SIZE define
- use the getpagesize() or sysconf(_SC_PAGESIZE) functions from unistd.h
people who are maintaining portable programs and want to work with upstream to
get the issue properly resolved (this should apply to everyone :P) may want
to introduce some sort of configure magic to see which of these may be
usuable (in order of preference):
- unistd.h + _SC_PAGESIZE (or _SC_PAGE_SIZE) + sysconf()
- unistd.h + getpagesize()
- asm/page.h + PAGE_SIZE
