i386: split smm helper (sysemu) smm is only really useful for sysemu, split in two modules around the CONFIG_USER_ONLY, in order to remove the ifdef and use the build system instead. add cpu_abort() when detecting attempts to enter SMM mode via SMI interrupt in user-mode, and assert that the cpu is not in SMM mode while translating RSM instructions.

i386: separate fpu_helper sysemu-only parts create a separate tcg/sysemu/fpu_helper.c for the sysemu-only parts. For user mode, some small #ifdefs remain in tcg/fpu_helper.c which do not seem worth splitting into their own user-mode module.

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_helper.c',`
