Description
change_page_attr has been removed from the upcoming Linux kernel 2.6.25. The kernel version test currently conditionally compiles some change_page_attr workarounds for kernels >= 2.4.20; this now needs to be upper-bounded as well.
Patch attached, lightly tested (I tried booting DragonFly BSD, and got to the boot menu, but then hit a known bug that DF BSD would freeze at the countdown screen)

Hmm, you checked this on a x86 platform, right? Because on AMD64 changing of the page attributes should be necessary.

No, this is on AMD64. The chage_page_attr function is simply not part of the 2.6.25 API at all -- there is a discussion in the LKML about this:

Right, on lkml.org they write that some has to use set_memory_nx()/set_memory_x(). You cannot simply ignore these calls. The fix should be in SVN now.
