parent[PATCH] Fix COW D-cache aliasing on fork (diff)
[PATCH] Pass vma argument to copy_user_highpage().
To allow a more effective copy_user_highpage() on certain architectures, a vma argument is added to the function and cow_user_page() allowing the implementation of these functions to check for the VM_EXEC bit. The main part of this patch was originally written by Ralf Baechle; Atushi Nemoto did the the debugging.
