From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Yonghua Huang <yonghua.huang@intel.com>
Date: Sat, 27 Oct 2018 02:10:21 +0800
Subject: [PATCH] kernel: remove deprecated VHM IOCTLs
below IOCTLs are wrapped into IC_SET_IRQLINE:
- IC_ASSERT_IRQLINE
- IC_DEASSERT_IRQLINE
- IC_PULSE_IRQLINE
Tracked-On: projectacrn/acrn-hypervisor#861
