Subject: [PATCH v2 1/9] x86/traps: add X86_NR_HW_TRAPS to <asm/trapnr.h>
Date: Fri, 14 May 2021 18:43:53 -0700	[thread overview]
Message-ID: <20210515014400.2999028-2-hpa@zytor.com> (raw)
In-Reply-To: <20210515014400.2999028-1-hpa@zytor.com>

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

The x86 architecture supports up to 32 trap vectors. Add that constant
to <asm/trapnr.h>.
