From a446a330117998a655e76c2e05ea46c01d365516 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Fri, 21 Feb 2020 17:16:25 +0100 Subject: [PATCH] x86/p2m: p2m_flags_to_type() deals only with "unsigned int" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit PTE flags, for now at least, get stored in "unsigned int". Hence there's no need to widen the values to "unsigned long" before processing them.
