Ok, maybe I have lots of shit in my eyes.... but it looks like get_order in asm-generic/page.h is broken.
AFAIK, get_order() should round up (and we have code here or there assuming such). However, it seems to assume that ilog2 rounds up, which it doesn't. It rounds down. At least the generic implementation seems to do so and the powerpc optimized one too. So I end up for example with get_order(0x1020) returning ... 0 (which explains some memory corruption problems I'm having on ppc32 among others0. So who is right and who is wrong ? Should we audit all users of these things ?
