* ARM: 5698/1: MMCI pass capabilities in platform dataLinus Walleij2009-09-15
| | | | | | | | | | | | This makes it possible to pass down the host controller capabilities for the MMCI driver using the platform data. It also provides the capabilties for the U300 implementation as an example, and makes sure the 4bit wide mode is set if this is requested by the ios() now that we can actually set that capability for a platform.

* ARM: 5697/1: MMCI Break out clock divider setupLinus Walleij2009-09-15
| | | | | | | | | | | | | This breaks out the clock divider set-up code from the mmci_set_ios() code and surrounds the two register writes with a host lock so we don't get collisions if (in future code) two code paths want to change the clock divider at the same time as can be the case if we get something like pre/post- clock frequency change notifications soonish.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a number of problems with the new key garbage collector: (1) A rogue semicolon in keyring_gc() was causing the initial count of dead keys to be miscalculated. (2) A missing return in keyring_gc() meant that under certain circumstances, the keyring semaphore would be unlocked twice. (3) The key serial tree iterator (key_garbage_collector()) part of the garbage collector has been modified to: (a) Complete each scan of the keyrings before setting the new timer. (b) Only set the new timer for keys that have yet to expire. This means that the new timer is now calculated correctly, and the gc doesn't get into a loop continually scanning for keys that have expired, and preventing other things from happening, like RCU cleaning up the old keyring contents. (c) Perform an extra scan if any keys were garbage collected in this one as a key might become garbage during a scan, and (b) could mean we don't set the timer again. (4) Made key_schedule_gc() take the time at which to do a collection run, rather than the time at which the key expires. This means the collection of dead keys (key type unregistered) can happen immediately. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>
| * KEYS: Unlock tasklist when exiting early from keyctl_session_to_parentMarc Dionne2009-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | When we exit early from keyctl_session_to_parent because of permissions or because the session keyring is the same as the parent, we need to unlock the tasklist. The missing unlock causes the system to hang completely when using keyctl(KEYCTL_SESSION_TO_PARENT) with a keyring shared with the parent.

| * | PM / Hibernate / Memory hotplug: Always use for_each_populated_zone()Gerald Schaefer2009-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use for_each_populated_zone() instead of for_each_zone() in hibernation code. This fixes a bug on s390, where we allow both config options HIBERNATION and MEMORY_HOTPLUG, so that we also have a ZONE_MOVABLE here. We only allow hibernation if no memory hotplug operation was performed, so in fact both features can only be used exclusively, but this way we don't need 2 differently configured (distribution) kernels. If we have an unpopulated ZONE_MOVABLE, we allow hibernation but run into a BUG_ON() in memory_bm_test/set/clear_bit() because hibernation code iterates through all zones, not only the populated zones, in several places. For example, swsusp_free() does for_each_zone() and then checks for pfn_valid(), which is true even if the zone is not populated, resulting in a BUG_ON() later because the pfn cannot be found in the memory bitmap. Replacing all occurences of for_each_zone() in hibernation code with for_each_populated_zone() would fix this issue.

| * | PM/Hibernate: Do not try to allocate too much memory too hard (rev. 2)Rafael J. Wysocki2009-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to avoid attempting to free too much memory too hard during hibernation, so estimate the minimum size of the image to use as the lower limit for preallocating memory. The approach here is based on the (experimental) observation that we can't free more page frames than the sum of: * global_page_state(NR_SLAB_RECLAIMABLE) * global_page_state(NR_ACTIVE_ANON) * global_page_state(NR_INACTIVE_ANON) * global_page_state(NR_ACTIVE_FILE) * global_page_state(NR_INACTIVE_FILE) minus * global_page_state(NR_FILE_MAPPED) Namely, if this number is subtracted from the number of saveable pages in the system, we get a good estimate of the minimum reasonable size of a hibernation image.

| * | PM/Hibernate: Do not release preallocated memory unnecessarily (rev. 2)Rafael J. Wysocki2009-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the hibernation code is now going to use allocations of memory to make enough room for the image, it can also use the page frames allocated at this stage as image page frames. The low-level hibernation code needs to be rearranged for this purpose, but it allows us to avoid freeing a great number of pages and allocating these same pages once again later, so it generally is worth doing.

With this patch struct pdev_archdata is added to struct platform_device, similar to struct dev_archdata in found in struct device. Useful for architecture code that needs to keep extra data associated with each platform device. Struct pdev_archdata is different from dev.platform_data, the convention is that dev.platform_data points to driver-specific data. It may or may not be required by the driver. The format of this depends on driver but is the same across architectures. The structure pdev_archdata is a place for architecture specific data. This data is handled by architecture specific code (for example runtime PM), and since it is architecture specific it should _never_ be touched by device driver code. Exactly like struct dev_archdata but for platform devices. [rjw: This change is for power management mostly and that's why it goes through the suspend tree.] Signed-off-by: Magnus Damm <damm@igel.co.jp> Acked-by: Kevin Hilman <khilman@deeprootsystems.com> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Rafael J.
