It's slightly tricky to get the memory layout correct, but ought not be *that* hard. The x86_64 port also had legacy absolute addresses to deal with. >> Can you describe the benefits with regard to this case?

The userland side can provide a static interface which defers to the kernel implementation. Ideally this would be done with an IFUNC relocation, but ARM binutils doesn't support that feature yet. Thankfully it is ABI compatible to replace a normal function with an IFUNC at a later date. r~ _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
