mm: introduce __vm_normal_page()
When dealing with the speculative fault path we should use the VMA's field
cached value stored in the vm_fault structure.
Currently vm_normal_page() is using the pointer to the VMA to fetch the
vm_flags value. This patch provides a new __vm_normal_page() which is
receiving the vm_flags flags value as parameter.
Note: The speculative path is turned on for architecture providing support
for special PTE flag. So only the first block of vm_normal_page is used
during the speculative path.
