From: Dave Martin <Dave.Martin@arm.com> ELF program properties will be needed for detecting whether to enable optional architecture or ABI features for a new ELF process. For now, there are no generic properties that we care about, so do nothing unless CONFIG_ARCH_USE_GNU_PROPERTY=y. Otherwise, the presence of properties using the PT_PROGRAM_PROPERTY phdrs entry (if any), and notify each property to the arch code. For now, the added code is not used.

As with the previous patch, this should also go to linux-fsdevel. The logic looks fine to me but I'm not sure the choice of returning -EIO is suitable in most cases. I think apart from kernel_read() returning an error, there rest look like malformed ELF notes, so rather -ENOEXEC. -- Catalin _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
