all right, i may have misread what's going on with
kmem_cache_alloc() and kmem_cache_zalloc(), and my earlier submission
may be entirely nonsense, since it involved transformations like this:
* it with privilege level 3 because the IVE uses non-privileged
accesses to these
* tables. IA-32 segmentation is used to protect against IA-32
accesses to them.

- vma = kmem_cache_alloc(vm_area_cachep, GFP_KERNEL);
+ vma = kmem_cache_zalloc(vm_area_cachep, GFP_KERNEL);
if (vma) {
- memset(vma, 0, sizeof(*vma));
vma->vm_mm = current->mm;
vma->vm_start = IA32_GDT_OFFSET;
vma->vm_end = vma->vm_start + PAGE_SIZE;
can someone briefly tell me if what i did makes sense?
