2009-03-24Driver core: Fix device_move() vs. dpm list ordering, v2Cornelia Huck
dpm_list currently relies on the fact that child devices will be registered after their parents to get a correct suspend order. Using device_move() however destroys this assumption, as an already registered device may be moved under a newly registered one. This patch adds a new argument to device_move(), allowing callers to specify how dpm_list should be adapted.

2009-03-24Driver core: implement uevent suppress in kobjectMing Lei
This patch implements uevent suppress in kobject and removes it from struct device, based on the following ideas: 1,Uevent sending should be one attribute of kobject, so suppressing it in kobject layer is more natural than in device layer. By this way, we can do it for other objects embedded with kobject. 2,It may save several bytes for each instance of struct device.(On my omap3(32bit ARM) based box, can save 8bytes per device object) This patch also introduces dev_set|get_uevent_suppress() helpers to set and query uevent_suppress attribute in case to help kobject as private part of struct device in future.

2009-02-19[S390] fix "mem=" handling in case of standby memoryHeiko Carstens
Standby memory detected with the sclp interface gets always registered with add_memory calls without considering the limitationt that the "mem=" kernel paramater implies. So fix this and only register standby memory that is below the specified limit. This fixes zfcpdump since it uses "mem=32M".

2009-02-11[S390] dasd: fix race in dasd timer handlingStefan Weinhuber
In dasd_device_set_timer and dasd_block_set_timer we interpret the return value of mod_timer in a wrong way. If the timer expires in the small window between our check of timer_pending and the call to mod_timer, then the timer will be set, mod_timer returns zero and we will call add_timer for a timer that is already pending. As del_timer and mod_timer do all the necessary checking themselves, we can simplify our code and remove the race a the same time.

2008-12-30kvm-s390: implement config_changed for virtio on s390Christian Borntraeger
This patch implements config_changed for the s390 virtio transport. We use the least significant bit of the interrupt parameter field to decide, if this interrupt should call the virtio virtqueue callback or the config_changed callback. This method is compatible with old host and guest code. Old 64 bit guests will not check the bit and trigger a harmless additional vring_interrupt call. Old host code will never set this bit, this is also safe. This patch also takes care of a potential future 31 bit virtio transport for s390. On 31 bit _LC_PFAULT_INTPARM and __LC_EXT_PARAMS are identical. We exploit the alignment of the token and fold the change bit into the lsb of the token itself.
