6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Peter Xu <peterx@xxxxxxxxxx> [ Upstream commit 0a845e0f6348ccfa2dcc8c450ffd1c9ffe8c4add ] pud_large() is always defined as pud_leaf(). Merge their usages. Chose pud_leaf() because pud_leaf() is a global API, while pud_large() is not.
