No need to duplicate the same define everywhere. Since the only user is stop-machine and the only provider is s390, we can use a default implementation of cpu_relax_yield in sched.h.

This patch removes support for use of NFS as a root filesystem from the kernel.

As there are no users left, we can remove cpu_relax_lowlatency.

Peter, here is v2 with some improved patch descriptions and some fixes. The previous version has survived one day of linux-next and I only changed small parts. So unless there is some other issue, feel free to pull (or to apply the patches) to tip/locking. The following changes since commit 07d9a380680d1c0eb51ef87ff2eab5c994949e69: Linux 4.9-rc2 (2016-10-23 17:10:14 -0700) are available in

For spinning loops people do often use barrier() or cpu_relax(). For most architectures cpu_relax and barrier are the same, but on some architectures cpu_relax can add some latency. For example on power,sparc64 and arc, cpu_relax can shift the CPU towards other hardware threads in an SMT environment. On s390 cpu_relax does even more, it uses an hypercall to the hypervisor to give up the timeslice.

For future rework of try_to_wake_up() we'd like to push part of that onto the CPU the task is actually going to run on, in order to do so we need a generic callback from the existing scheduler IPI. This patch introduces such a generic callback: scheduler_ipi() and implements it as a NOP. I visited existing smp_send_reschedule() implementations and tried to add a call to scheduler_ipi() in

This patch removes IP autoconfiguration (CONFIG_IP_PNP and friends) support from the kernel, and ensures that using NFS as the root filesystem (CONFIG_NFS_ROOT) will no longer work. b/arch/alpha/defconfig | 1 b/arch/arm/def-configs/a5k | 1 b/arch/arm/def-configs/adi_evb | 4 b/arch/arm/def-configs/adsbitsy | 4

Change Index.arch to the type (Arch of string | GuessedArch of string). In a future commit, the index parser will allow arch not to be set for some cases. Thus arch value will be guessed by inspecting the image. However we need to distinguish between a set value and a guessed one. Using this new type will help it: match arch with | Arch s -> (* This is a set value *) |
