Subject: [PATCH 12/13] ppc64: Remove redundant PTE checks
|
|
|
|
Remove redundant checks for PTE (Page Table Entry) because those
|
|
conditions are already covered.
|
|
|
|
if (!(pte & _PAGE_PRESENT)) {
|
|
...
|
|
return FALSE;
|
|
}
|
|
|
|
if (!pte)
|
|
return FALSE;
|
|
|
|
The second pte check is redundant because it holds true only when pte is
|
|
0. If pte is 0 then (!(pte & _PAGE_PRESENT)) is true and it will return
|
|
false. So there is no need for one more pte check.
