From e6c2b3cc408edc2695352dbfa991d6d33d2e5cd5 Mon Sep 17 00:00:00 2001 From: Ethan Chen Date: Mon, 3 Sep 2018 19:11:39 -0700 Subject: [PATCH] uapi: Define __BITS_PER_LONG based on compiler target * We may compile 32-bit ARM code against these kernel headers in many situations, so provide a compiler-defined method of obtaining the width of long.
