[PATCH v2 24/32] sparc: define __smp_xxx

This defines __smp_xxx barriers for sparc, for use by virtualization. smp_xxx barriers are removed as they are defined correctly by asm-generic/barriers.h Signed-off-by: Michael S. Tsirkin Acked-by: Arnd Bergmann --- arch/sparc/include/asm/barrier_64.h | 8

[PATCH v2 27/32] x86: define __smp_xxx

This defines __smp_xxx barriers for x86, for use by virtualization. smp_xxx barriers are removed as they are defined correctly by asm-generic/barriers.h Signed-off-by: Michael S. Tsirkin Acked-by: Arnd Bergmann --- arch/x86/include/asm/barrier.h | 31

[PATCH v2 20/32] metag: define __smp_xxx

This defines __smp_xxx barriers for metag, for use by virtualization. smp_xxx barriers are removed as they are defined correctly by asm-generic/barriers.h Note: as __smp_XX macros should not depend on CONFIG_SMP, they can not use the existing fence() macro since that is defined differently

[PATCH v2 11/32] mips: reuse asm-generic/barrier.h

On mips dma_rmb, dma_wmb, smp_store_mb, read_barrier_depends, smp_read_barrier_depends, smp_store_release and smp_load_acquire match the asm-generic variants exactly. Drop the local definitions and pull in asm-generic/barrier.h instead. This is in preparation to refactoring this code area.

[PATCH v2 12/32] x86/um: reuse asm-generic/barrier.h

On x86/um CONFIG_SMP is never defined. As a result, several macros match the asm-generic variant exactly. Drop the local definitions and pull in asm-generic/barrier.h instead. This is in preparation to refactoring this code area. Signed-off-by: Michael S. Tsirkin Acked-by:

[PATCH v2 01/32] lcoking/barriers, arch: Use smp barriers in smp_store_release()

From: Davidlohr Bueso With commit b92b8b35a2e ("locking/arch: Rename set_mb() to smp_store_mb()") it was made clear that the context of this call (and thus set_mb) is strictly for CPU ordering, as opposed to IO. As such all archs should use the smp variant of mb(), respecting

[PATCH v2 10/32] metag: reuse asm-generic/barrier.h

On metag dma_rmb, dma_wmb, smp_store_mb, read_barrier_depends, smp_read_barrier_depends, smp_store_release and smp_load_acquire match the asm-generic variants exactly. Drop the local definitions and pull in asm-generic/barrier.h instead. This is in preparation to refactoring this code area.

[PATCH v2 02/32] asm-generic: guard smp_store_release/load_acquire

Allow architectures to override smp_store_release and smp_load_acquire by guarding the defines in asm-generic/barrier.h with ifndef directives. This is in preparation to reusing asm-generic/barrier.h on architectures which have their own definition of these macros. Signed-off-by: Michael S.

[PATCH v2 08/32] arm: reuse asm-generic/barrier.h

On arm smp_store_mb, read_barrier_depends, smp_read_barrier_depends, smp_store_release, smp_load_acquire, smp_mb__before_atomic and smp_mb__after_atomic match the asm-generic variants exactly. Drop the local definitions and pull in asm-generic/barrier.h instead. This is in preparation to

[PATCH v2 05/32] powerpc: reuse asm-generic/barrier.h

On powerpc read_barrier_depends, smp_read_barrier_depends smp_store_mb(), smp_mb__before_atomic and smp_mb__after_atomic match the asm-generic variants exactly. Drop the local definitions and pull in asm-generic/barrier.h instead. This is in preparation to refactoring this code area.

[PATCH v2 04/32] ia64: reuse asm-generic/barrier.h

On ia64 smp_rmb, smp_wmb, read_barrier_depends, smp_read_barrier_depends and smp_store_mb() match the asm-generic variants exactly. Drop the local definitions and pull in asm-generic/barrier.h instead. This is in preparation to refactoring this code area. Signed-off-by: Michael S. Tsirkin
