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/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc-gcc --version # < git log --format=%s --max-count=1 fedb8da96355f5f64353625bf96dc69423ad1826 # < make -s -j 120 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- axs101_defconfig # Added to kconfig CONFIG_INITRAMFS_SOURCE="" # make -s -j 120 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- olddefconfig # make -s -j 120 ARCH=arc O=/kisskb/build/linus_axs101_defconfig_arcompact CROSS_COMPILE=/opt/cross/kisskb/arcompact-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc- <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] In file included from /kisskb/src/include/asm-generic/bug.h:18:0, from /kisskb/src/arch/arc/include/asm/bug.h:32, from /kisskb/src/include/linux/bug.h:5, from /kisskb/src/include/linux/mmdebug.h:5, from /kisskb/src/include/linux/gfp.h:5, from /kisskb/src/include/linux/slab.h:15, from /kisskb/src/mm/nobootmem.c:14: /kisskb/src/mm/nobootmem.c: In function '__free_pages_memory': /kisskb/src/include/linux/kernel.h:812:29: warning: comparison of distinct pointer types lacks a cast [enabled by default] (!!(sizeof((typeof(x) )1 == (typeof(y) )1))) ^ /kisskb/src/include/linux/kernel.h:826:4: note: in expansion of macro '__typecheck' (__typecheck(x, y) && __no_side_effects(x, y)) ^ /kisskb/src/include/linux/kernel.h:836:24: note: in expansion of macro '__safe_cmp' __builtin_choose_expr(__safe_cmp(x, y), \ ^ /kisskb/src/include/linux/kernel.h:845:19: note: in expansion of macro '__careful_cmp' #define min(x, y) __careful_cmp(x, y, <) ^ /kisskb/src/mm/nobootmem.c:104:11: note: in expansion of macro 'min' order = min(MAX_ORDER - 1UL, __ffs(start)); ^ /kisskb/src/net/xfrm/xfrm_policy.c: In function '__xfrm_policy_check': /kisskb/src/net/xfrm/xfrm_policy.c:2380:15: warning: array subscript is above array bounds [-Warray-bounds] if (sp->xvec[k]->props.mode != XFRM_MODE_TRANSPORT) { ^ /kisskb/src/net/ipv4/tcp_input.c: In function 'tcp_data_queue': /kisskb/src/net/ipv4/tcp_input.c:4313:49: warning: array subscript is above array bounds [-Warray-bounds] tp->selective_acks[i-1] = tp->selective_acks[i]; ^ Completed OK # rm -rf /kisskb/build/linus_axs101_defconfig_arcompact # Build took: 0:00:22.229727
