However, in one heavily interrupt-driven SMT1 # workload, some regression was observed. This patch adds a kvm_hv # module parameter called h_ipi_redirect to control this feature. # # The default value for this tunable is 1 - that is enable the feature. # # Signed-off-by: Suresh Warrier # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 6f5701c04edc0b4d00d482117c89a7a13d647b5f # < make -s -j 8 ARCH=powerpc O=/kisskb/build/mpe-0day_ppc44x_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc44x_defconfig In file included from scripts/kconfig/zconf.tab.c:2576: /kisskb/src/scripts/kconfig/confdata.c: In function 'conf_write': /kisskb/src/scripts/kconfig/confdata.c:770:19: warning: '%s' directive writing likely 7 or more bytes into a region of size between 1 and 4097 [-Wformat-overflow=] 770 | sprintf(newname, "%s%s", dirname, basename);
