Subject: [PATCH 1/3] target/i386: Renumber EXCP_SYSCALL
Date: Tue, 14 Jan 2020 11:09:19 -1000	[thread overview]
Message-ID: <20200114210921.11216-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200114210921.11216-1-richard.henderson@linaro.org>

We are not short of numbers for EXCP_*.  There is no need to confuse things
by having EXCP_VMEXIT and EXCP_SYSCALL overlap, even though the former is
only used for system mode and the latter is only used for user mode.
