However, Jeff Law recently indicated on gcc-patches that this is # not correct. There are various degrees of out-of-order execution all the # way back to the PA7xxx processor series (hit-under-miss). The PA8xxx # series has full out-of-order execution for both integer operations, and # loads and stores. # # This is described in the following article: # http://web.archive.org/web/20040214092531/http://www.cpus.hp.com/technical_references/advperf.shtml # # For this reason, we need to define mb() and to insert a memory barrier # before the store unlocking spinlocks. This ensures that all memory # accesses are complete prior to unlocking. The ldcw instruction performs # the same function on entry. # # Signed-off-by: John David Anglin <dave.anglin@bell.net> # Cc: stable@vger.kernel.org # 4.0+ # Signed-off-by: Helge Deller <deller@gmx.de> # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 fedb8da96355f5f64353625bf96dc69423ad1826 # < make -s -j 48 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- randconfig KCONFIG_SEED=0x4F8C34D8 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # yes \n \| make -s -j 48 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- /kisskb/src/drivers/gpu/drm/bridge/cdns-dsi.c:1340:12: warning: 'cdns_dsi_resume' defined but not used [-Wunused-function] static int cdns_dsi_resume(struct device dev) ^ /kisskb/src/drivers/gpu/drm/bridge/cdns-dsi.c:1353:12: warning: 'cdns_dsi_suspend' defined but not used [-Wunused-function] static int cdns_dsi_suspend(struct device dev) ^ Completed OK # rm -rf /kisskb/build/linus-rand_x86_64-randconfig_um-x86_64 # Build took: 0:02:24.511266
