This patch series implement arch_cmpxchg[64]_local for arc, openrisc and hexagon.
For architectures that support native cmpxchg, we'd like to implement arch_cmpxchg[64]_local with the native variants of supported data size. If not, the generci_cmpxchg[64]_local will be used. wuqiang.matt (4): locking/atomic: arc: data size checking in arch_cmpxchg locking/atomic: arc: arch_cmpxchg[64]_local undefined locking/atomic: openrisc: arch_cmpxchg[64]_local undefined locking/atomic: hexagon: arch_cmpxchg[64]_local undefined arch/arc/include/asm/cmpxchg.h | 40 ++++++++++++++++++---- arch/hexagon/include/asm/cmpxchg.h | 51 ++++++++++++++++++++++++++++- arch/openrisc/include/asm/cmpxchg.h | 6 ++++ 3 files changed, 90 insertions(+), 7 deletions(-) -- 2.40.1 _______________________________________________ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc
