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/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux-gcc --version # < git log --format=%s --max-count=1 fedb8da96355f5f64353625bf96dc69423ad1826 # < make -s -j 10 ARCH=parisc O=/kisskb/build/linus_a500_defconfig_parisc64 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux- a500_defconfig # make -s -j 10 ARCH=parisc O=/kisskb/build/linus_a500_defconfig_parisc64 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa64-linux/bin/hppa64-linux- <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] /kisskb/src/crypto/ablkcipher.c: In function 'crypto_ablkcipher_report': /kisskb/src/crypto/ablkcipher.c:374:2: warning: 'strncpy' specified bound 64 equals destination size [-Wstringop-truncation] strncpy(rblkcipher.geniv, alg->cra_ablkcipher.geniv ?: "<default>", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sizeof(rblkcipher.geniv));
