Subject: [PATCH v2 1/5] target/i386: Renumber EXCP_SYSCALL
Date: Thu, 16 Jan 2020 09:43:37 -1000
Message-ID: <20200116194341.402-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200116194341.402-1-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.
