They are applied per target, and not in config-host. So unpoisoining them opens the possibility to miss something. I would stick to clean up those ifdef instead, by exposing interface to all code, and link appropriate stubs depending on the variant built. > Suggested-by: Richard Henderson <richard.henderson@linaro.org> > Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> > --- > include/exec/poison.h | 4 ---- > scripts/make-config-p oison.sh | 4 ++++ > 2 files changed, 4 insertions(+), 4 deletions(-) > > diff --git a/include/exec/poison.h b/include/exec/poison.h > index 00aedc41d82..0574d683f6a 100644 > --- a/include/exec/poison.h > +++ b/include/exec/poison.h > @@ -62,11 +62,7 @@ > #pragma GCC poison CONFIG_SPARC_DIS > #pragma GCC poison CONFIG_XTENSA_DIS > > -#pragma GCC poison CONFIG_HVF > #pragma GCC poison CONFIG_LINUX_USER > -#pragma GCC poison CONFIG_KVM > -#pragma GCC poison CONFIG_WHPX > -#pragma GCC poison CONFIG_XEN > > #ifndef COMPILING_SYSTEM_VS_USER > #pragma GCC poison CONFIG_USER_ONLY > diff --git a/scripts/make-config-poison.sh b/scripts/make-config-poison.sh > index 2b36907e239..09d2384745f 100755 > --- a/scripts/make-config-poison.sh > +++ b/scripts/make-config-poison.sh > @@ -8,6 +8,10 @@ fi > # but filter out several which are handled manually. > exec sed -n \ > -e' /CONFIG_TCG/d' \ > + -e' /CONFIG_HVF/d' \ > + -e' /CONFIG_KVM/d' \ > + -e' /CONFIG_WHPX/d' \ > + -e' /CONFIG_XEN/d' \ > -e '/CONFIG_USER_ONLY/d' \ > -e '/CONFIG_SOFTMMU/d' \ > -e '/^#define / {' \

OK, so IIUC this is the same reasoning than previous patch comment, always declare kvm_enabled() so code elision isn't possible anymore, then remove all CONFIG_KVM #ifdef'ry? > >> Suggested-by: Richard Henderson <richard.henderson@linaro.org> >> Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> >> --- >> include/exec/poison.h | 4 ---- >> scripts/make-config-p oison.sh | 4 ++++ >> 2 files changed, 4 insertions(+), 4 deletions(-) >> >> diff --git a/include/exec/poison.h b/include/exec/poison.h >> index 00aedc41d82..0574d683f6a 100644 >> --- a/include/exec/poison.h >> +++ b/include/exec/poison.h >> @@ -62,11 +62,7 @@ >> #pragma GCC poison CONFIG_SPARC_DIS >> #pragma GCC poison CONFIG_XTENSA_DIS >> -#pragma GCC poison CONFIG_HVF >> #pragma GCC poison CONFIG_LINUX_USER >> -#pragma GCC poison CONFIG_KVM >> -#pragma GCC poison CONFIG_WHPX >> -#pragma GCC poison CONFIG_XEN >> #ifndef COMPILING_SYSTEM_VS_USER >> #pragma GCC poison CONFIG_USER_ONLY >> diff --git a/scripts/make-config-poison.sh b/scripts/make-config- >> poison.sh >> index 2b36907e239..09d2384745f 100755 >> --- a/scripts/make-config-poison.sh >> +++ b/scripts/make-config-poison.sh >> @@ -8,6 +8,10 @@ fi >> # but filter out several which are handled manually. >> exec sed -n \ >> -e' /CONFIG_TCG/d' \ >> + -e' /CONFIG_HVF/d' \ >> + -e' /CONFIG_KVM/d' \ >> + -e' /CONFIG_WHPX/d' \ >> + -e' /CONFIG_XEN/d' \ >> -e '/CONFIG_USER_ONLY/d' \ >> -e '/CONFIG_SOFTMMU/d' \ >> -e '/^#define / {' \ >
