From d2b2250c3e565038a746b5db1de2af20a6468f02 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 11 Jun 2018 11:55:04 -0700 Subject: ia64: disable CONFIG_PERFMON at least for now Al noted that the semantics of the ia64 perfmon mmap() is really wrong, and can cause serious VM problems. Before we look at whether it needs to be fixed, let's see if anybody even uses it, and mark it broken. It may be that we can just remove the code entirely.
