2013-08-23sysfs: create __ATTR_WO()Greg Kroah-Hartman
This creates the macro __ATTR_WO() for write-only attributes, instead of having to "open define" them. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-08-23driver-core: platform: convert bus code to use dev_groupsGreg Kroah-Hartman
The dev_attrs field of struct bus_type is going away soon, dev_groups should be used instead. This converts the platform bus code to use the correct field. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-08-22Kconfig: Remove hotplug enable hints in CONFIG_KEXEC help textsGeert Uytterhoeven
commit 40b313608ad4ea655addd2ec6cdd106477ae8e15 ("Finally eradicate CONFIG_HOTPLUG") removed remaining references to CONFIG_HOTPLUG, but missed a few plain English references in the CONFIG_KEXEC help texts.

2013-08-22w1: add attribute groups to struct w1_family_opsGreg Kroah-Hartman
This lets w1 slave drivers declare an attribute group, and not have to create/destroy sysfs files directly. All w1 slave drivers will be fixed to use this field up in follow-on patches to this one.

2013-08-22w1: use default attribute groups for w1 slave devicesGreg Kroah-Hartman
As we have 2 sysfs files for the w1 slave devices, let the driver core create / destroy them automatically by setting the default attribute group for them, saving code and housekeeping logic. Acked-by: Evgeniy Polyakov <zbr@ioremap.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-08-22w1: remove race with sysfs file creationGreg Kroah-Hartman
W1 slave sysfs files are created _after_ userspace is notified that the device has been added to the system. Fix that race by moving the creation/remove of the files to the bus notifier that is there for doing this type of thing.

2013-08-22sysfs.h: remove attr_name() macroGreg Kroah-Hartman
Gotta love a macro that doesn't reduce the typing you have to do. Also, only the driver core, and one network driver uses this. The driver core functions will be going away soon, and I'll convert the network driver soon to not need this as well, so delete it for now before anyone else gets some bright ideas and wants to use it.

2013-08-22acpi: bgrt: fix build error due to attribute changeGreg Kroah-Hartman
No need to call sysfs_bin_attr_init, as the attribute is not dynamically created. Also, we renamed the attribute, so this one isn't even valid anymore.

2013-08-21sysfs: group.c: move EXPORT_SYMBOL_GPL() to the proper locationGreg Kroah-Hartman
This fixes up the coding style issue of incorrectly placing the EXPORT_SYMBOL_GPL() macro, it should be right after the function itself, not at the end of the file. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-08-21sysfs: add sysfs_create/remove_groups()Greg Kroah-Hartman
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. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-08-21drivers: base: use standard device online/offline for state changeSeth Jennings
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 Jennings
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 Jennings
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: reduce add_memory_section() for boot-time onlySeth Jennings

2013-08-21drivers: base: unshare add_memory_section() from hotplugSeth Jennings
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().

2013-08-21drivers: base: use device get/put functionsSeth Jennings
Use the [get|put]_device functions for ref'ing the memory block device rather than the kobject functions which should be hidden away by the device layer. Signed-off-by: Seth Jennings <sjenning@linux.vnet.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-08-21drivers: base: move mutex lock out of add_memory_section()Seth Jennings
There is no point in releasing the mutex for each section that is added during boot time. Just hold it over the entire initialization loop. Signed-off-by: Seth Jennings <sjenning@linux.vnet.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-08-21ACPI: bgrt: take advantage of binary sysfs groupsGreg KH
