From 6042b8c7c08cad7a8bdc0456c619ae941962b40a Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck II Date: Mon, 2 Oct 2017 20:33:35 +0100 Subject: ARM: 8701/1: fix sparse flags for build on 64bit machines By default sparse uses the characteristics of the build machine to infer things like the wordsize. This is fine when doing native builds but for ARM it's, I suspect, very rarely the case and if the build are done on a 64bit machine we get a bunch of warnings like: 'cast truncates bits from constant value (... becomes ...)' Fix this by adding the -m32 flags for sparse.
