Christophe Leroy 5865e608bc powerpc/32s: Add missing call to kuep_lock on syscall entry ... commit 57fdfbce89137ae85cd5cef48be168040a47dd13 upstream. Userspace Execution protection and fast syscall entry were implemented independently from each other and were both merged in kernel 5.2, leading to syscall entry missing userspace execution protection. On syscall entry, execution of user space memory must be locked in the same way as on exception entry.
