Coming back to this problem... Reading ttbr0 worked for me on ARM, reading cr3 worked on x86. Now I'm looking for a similar thing on MIPS. I.e. I need a pointer to the process' translation table - something that can be compared to task->mm->pgd (after virt2phys conversion). I'd appreciate any idea!
