Let the platform's Kconfig to select the clock instead of having a reverse dependency from the driver to the platform options. Add the COMPILE_TEST option for the compilation test coverage. Due to the non portable 'delay' code, this driver is only compilable on ARM. Signed-off-by:

Let the platform's Kconfig to select the clock instead of having a reverse dependency from the driver to the platform options. Add the COMPILE_TEST option for the compilation test coverage. This change is debatable as the option itself in the Kconfig allows to select the driver for the platform or not. This change will make the prcmu timer always selected. Signed-off-by:

Increase the compilation test coverage by adding the COMPILE_TEST option. The driver depends on the common clock framework, thus the dependency added on COMMON_CLK. Signed-off-by:

In order to be consistent with the rest of the drivers compilation, let's introduce the COMPILE_TEST option. Unfortunately, the delay.h code is not portable, so the compilation test coverage will be restricted to the ARM architecture. Signed-off-by:

When we try to compile a clocksource driver with the COMPILE_TEST option, we can't select the GENERIC_SCHED_CLOCK because the sched_clock() symbol will be duplicated with the one defined for the x86. In order to fix that, we don't select the GENERIC_SCHED_CLOCK in the driver Kconfig's file but we define some empty functions for the different symbols in order to prevent the unresolved ones. This patch fixes the COMPILE_TEST option for the compile test coverage for the clocksource drivers. Without this patch, we can't add the COMPILE_TEST option for the clocksource drivers using the GENERIC_SCHED_CLOCK. Signed-off-by:

Allow the timer core to change the smp affinity of the broadcast timer irq by setting CLOCK_EVT_FEAT_DYNIRQ flag. This reduces interrupt pressure and wakeups on CPU0 as well as vastly reducing the number of timer broadcast IPIs. Signed-off-by:

We cache all hotpath members of a clocksource in the time keeper core. So there is no requirement in general to cache line align struct clocksource. Remove the enforces alignment. That allows users which need to wrap struct clocksource into their own struct to align the struct without getting extra padding. Signed-off-by:

Merge slub bulk allocator updates from Andrew Morton: "This missed the merge window because I was waiting for some repairs to come in. Nothing actually uses the bulk allocator yet and the changes to other code paths are pretty small. And the net guys are waiting for this so they can start merging the client code" More comments from Jesper Dangaard Brouer: "The kmem_cache_alloc_bulk() call, in mm/slub.c, were included in previous kernel. The present version contains a bug. Vladimir Davydov noticed it contained a bug, when kernel is compiled with CONFIG_MEMCG_KMEM (see commit 03ec0ed5: "slub: fix kmem cgroup bug in kmem_cache_alloc_bulk"). Plus the mem cgroup counterpart in kmem_cache_free_bulk() were missing (see commit 03374518 "slub: add missing kmem cgroup support to kmem_cache_free_bulk"). I don't consider the fix stable-material because there are no in-tree users of the API. But with known bugs (for memcg) I cannot start using the API in the net-tree" * emailed patches from Andrew Morton <akpm@linux-foundation.org>: slab/slub: adjust kmem_cache_alloc_bulk API slub: add missing kmem cgroup support to kmem_cache_free_bulk slub: fix kmem cgroup bug in kmem_cache_alloc_bulk slub: optimize bulk slowpath free by detached freelist slub: support for bulk free with SLUB freelists
