From e8733482f59e23a8bf79526b7f83ed0d0ff5a9b2 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Fri, 18 Nov 2022 20:05:21 +0300 Subject: [PATCH] KVM: VMX: don't use "unsigned long" in vmx_vcpu_enter_exit() __vmx_vcpu_run_flags() returns "unsigned int" and uses only 2 bits of it so using "unsigned long" is very much pointless. Furthermore, __vmx_vcpu_run() and vmx_spec_ctrl_restore_host() take an "unsigned int", i.e. actually relying on an "unsigned long" value won't work.
