i386: split svm_helper into sysemu and stub-only user For now we just copy over the previous user stubs, but really, everything that requires s->cpl == 0 should be impossible to trigger from user-mode emulation. Later on we should add a check that asserts this easily f.e.: static bool check_cpl0(DisasContext *s) { int cpl = s->cpl; #ifdef CONFIG_USER_ONLY assert(cpl == 3); #endif if (cpl != 0) { gen_exception(s, EXCP0D_GPF, s->pc_start - s->cs_base); return false; } return true; } Signed-off-by: Claudio Fontana <cfontana@suse.de> Cc: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20210322132800.7470-17-cfontana@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> 2021-03-22 16:27:52 +03:00			`'svm_stubs.c',`
