2013-08-22sysfs: fix placement of EXPORT_SYMBOL()Greg Kroah-Hartman3-20/+8
The export should happen after the function, not at the bottom of the file, so fix that up. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-08-22sysfs: group.c: add kerneldoc for sysfs_remove_groupGreg Kroah-Hartman1-2/+10
sysfs_remove_group() never had kerneldoc, so add it, and fix up the kerneldoc for sysfs_remove_groups() which didn't specify the parameters properly. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-08-22sysfs: group.c: move EXPORT_SYMBOL_GPL() to the proper locationGreg Kroah-Hartman1-6/+3

2013-08-22sysfs: add sysfs_create/remove_groups()Greg Kroah-Hartman5-61/+64
These functions are being open-coded in 3 different places in the driver core, and other driver subsystems will want to start doing this as well, so move it to the sysfs core to keep it all in one place, where we know it is written properly.

2013-08-21drivers: base: use standard device online/offline for state changeSeth Jennings2-82/+58
There are two ways to set the online/offline state for a memory block: echo 0|1 > online and echo online|online_kernel|online_movable|offline > state. The state attribute can online a memory block with extra data, the "online type", where the online attribute uses a default online type of ONLINE_KEEP, same as echo online > state. Currently there is a state_mutex that provides consistency between the memory block state and the underlying memory. The problem is that this code does a lot of things that the common device layer can do for us, such as the serialization of the online/offline handlers using the device lock, setting the dev->offline field, and calling kobject_uevent(). This patch refactors the online/offline code to allow the common device_[online|offline] functions to be used. The result is a simpler and more common code path for the two state setting mechanisms. It also removes the state_mutex from the struct memory_block as the memory block device lock provides the state consistency. No functional change is intended by this patch.

2013-08-21drivers: base: refactor add_memory_section() to add_memory_block()Seth Jennings1-27/+21
Right now memory_dev_init() maintains the memory block pointer between iterations of add_memory_section(). This is nasty. This patch refactors add_memory_section() to become add_memory_block(). The refactoring pulls the section scanning out of memory_dev_init() and simplifies the signature.

2013-08-21drivers: base: remove improper get/put in add_memory_section()Seth Jennings1-4/+2
The path through add_memory_section() when the memory block already exists uses flawed refcounting logic. A get_device() is done on a memory block using a pointer that might not be valid as we dropped our previous reference and didn't obtain a new reference in the proper way. Lets stop pretending and just remove the get/put. The mem_sysfs_mutex, which we hold over the entire init loop now, will prevent the memory blocks from disappearing from under us.

2013-08-21drivers: base: unshare add_memory_section() from hotplugSeth Jennings1-3/+16
add_memory_section() is currently called from both boot time and run time via hotplug and there is a lot of nastiness to allow for shared code including an enum parameter to convey the calling context to add_memory_section(). This patch is the first step in breaking up the messy code sharing by pulling the hotplug path for add_memory_section() directly into register_new_memory().

2013-08-13driver core / cpu: Check if NUMA node is valid before bringing CPU upRafael J. Wysocki1-1/+5
There is a potential race condition between cpu_subsys_online() and either acpi_processor_remove() or remove_memory() that execute try_offline_node(). Namely, it is possible that cpu_subsys_online() will run right after the CPUs NUMA node has been put offline and cpu_to_node() executed by it will return NUMA_NO_NODE (-1). In that case the CPU is gone and it doesn't make sense to call cpu_up() for it, so make cpu_subsys_online() return -ENODEV then. Signed-off-by: Rafael J.

2013-07-29cpu topology: remove stale arch_provides_topology_pointers and ↵Hanjun Guo1-20/+0
define_siblings_show_map/list() arch_provides_topology_pointers was introduced in commit 23ca4bba3 (x86: cleanup early per cpu variables/accesses v4) to indicate pointers to the topology cpumask_t maps are valid to avoid copying data on to/off of the stack. But later in commit fbd59a8d (cpumask: Use topology_core_cpumask()/ topology_thread_cpumask()), the pointers to the topology struct cpumask maps are always valid. After that commit, the only difference is that there is a redundant "unsigned int cpu = dev->id;" if arch_provides_topology_pointers defined, but dev->id is type 'u32' which devolves to 'unsigned int' on all supported arches. So this arch_provides_topology_pointers define is pointless and only cause obfuscation now, remove it. Tested on x86 machine, topology information in sys/devices/system/cpu/ cpuX/topology/ is the same after appling this patch set.
