From d939474b3d92624744a334c9e5f58ce3934584b5 Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Sun, 5 Feb 2023 18:17:04 -0500 Subject: s390/mm: define private VM_FAULT_* reasons from top bits The current definition already collapse with the generic definition of vm_fault_reason. Move the private definitions to allocate bits from the top of uint so they won't collapse anymore.
