[PULL 2/6] target/i386: Renumber EXCP_SYSCALL

Posted by Laurent Vivier 9 weeks ago
From: Richard Henderson <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.
