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/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < git log --format=%s --max-count=1 fedb8da96355f5f64353625bf96dc69423ad1826 # < make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- randconfig KCONFIG_SEED=0x4E9FEBA0 # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # yes \n \| make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:40: LSE atomics not supported by binutils <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] ERROR: "__sync_icache_dcache" [drivers/xen/xen-privcmd.ko] undefined! /kisskb/src/scripts/Makefile.modpost:92: recipe for target '__modpost' failed make[2]: * [__modpost] Error 1 /kisskb/src/Makefile:1206: recipe for target 'modules' failed make[1]: * [modules] Error 2 Makefile:146: recipe for target 'sub-make' failed make: * [sub-make] Error 2 Command 'make -s -j 48 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus-rand_arm64-randconfig_arm64 # Build took: 0:02:12.258998
