linux-toradex.git/include/asm-xtensa/processor.h, branch v2.6.18-rc7 Linux kernel for Apalis and Colibri modules [PATCH] Make cpu_relax() imply barrier() on all arches 2006-07-12T19:56:45+00:00 Chase Venters chase.venters@clientec.com 2006-07-08T16:10:29+00:00 f6dc8c5b8e04ce28720155383e971561a23899d5 During the recent discussion of taking 'volatile' off of the spinlock, I noticed that while most arches #define cpu_relax() such that it implies barrier(), some arches define cpu_relax() to be empty. This patch changes the definition of cpu_relax() for frv, h8300, m68knommu, sh, sh64, v850 and xtensa from an empty while(0) to the compiler barrier().

During the recent discussion of taking 'volatile' off of the spinlock, I
noticed that while most arches #define cpu_relax() such that it implies
barrier(), some arches define cpu_relax() to be empty.

This patch changes the definition of cpu_relax() for frv, h8300, m68knommu,
sh, sh64, v850 and xtensa from an empty while(0) to the compiler barrier().
