Subject: [PATCH 2/6] x86/irqvector: add NR_EXTERNAL_VECTORS and NR_SYSTEM_VECTORS
Date: Mon, 10 May 2021 17:55:27 -0700	[thread overview]
Message-ID: <20210511005531.1065536-3-hpa@zytor.com> (raw)
In-Reply-To: <20210511005531.1065536-1-hpa@zytor.com>

From: "H. Peter Anvin (Intel)" <hpa@zytor.com>

Add defines for the number of external vectors and number of system
vectors instead of requiring the use of (FIRST_SYSTEM_VECTOR -
FIRST_EXTERNAL_VECTOR) and (NR_VECTORS - FIRST_SYSTEM_VECTOR)
respectively.
