Nutshell few patches to improve mmu_notifier : - patch 1/3 allow to free resources when mm_struct is destroy. - patch 2/3 provide context informations to mmu_notifier listener. - patch 3/3 pass vma to range_start/range_end to avoid duplicate vma lookup inside the listener. I restricted myself to set of less controversial patches and i believe i have addressed all comments that were previously made. Thanks again for all feedback, i hope this version is the good one. This is somewhat of a v5 but i do not include core hmm with those patches.
