* firmware: export firmware_kset so that people can use that instead of the ↵Greg Kroah-Hartman2008-01-24
| | | | | | | | | | | | | | | braindead firmware_register interface Needed for future firmware subsystem cleanups. In the end, the firmware_register/unregister functions will be deleted entirely, but we need this symbol so that subsystems can migrate over.

* fix struct user_info export's sysfs interactionKay Sievers2008-01-24
| | | | | | | | | | | | | | | | Clean up the use of ksets and kobjects. Kobjects are instances of objects (like struct user_info), ksets are collections of objects of a similar type (like the uids directory containing the user_info directories). So, use kobjects for the user_info directories, and a kset for the "uids" directory. On object cleanup, the final kobject_put() was missing.

* Driver Core: add kobj_attribute handlingKay Sievers2008-01-24
| | | | | | | | | | | | Add kobj_sysfs_ops to replace subsys_sysfs_ops. There is no need for special kset operations, we want to be able to use simple attribute operations at any kobject, not only ksets. The whole concept of any default sysfs attribute operations will go away with the upcoming removal of subsys_sysfs_ops.

* PM: Acquire device locks on suspendRafael J. Wysocki2008-01-24
| | | | | | | | | | | | | | | | | | This patch reorganizes the way suspend and resume notifications are sent to drivers. The major changes are that now the PM core acquires every device semaphore before calling the methods, and calls to device_add() during suspends will fail, while calls to device_del() during suspends will block. It also provides a way to safely remove a suspended device with the help of the PM core, by using the device_pm_schedule_removal() callback introduced specifically for this purpose, and updates two drivers (msr and cpuid) that need to use it.

The reservation up to page size of memory after init data was previously not done if BLK_DEV_INITRD was undefined. This caused a kernel oops when init memory pages were freed after startup, data placed in the same page as the last init memory would also be freed and reused, with disastrous results. - Use macros for initcalls and .text sections. - Replace hardcoded page size constant with PAGE_SIZE define. - Change include/asm-cris/page.h to use the _AC macro to instead of testing __ASSEMBLY__.

* lockdep: fix workqueue creation API lockdep interactionJohannes Berg2008-01-16
| | | | | | | | | | | | | | | | | | | | Dave Young reported warnings from lockdep that the workqueue API can sometimes try to register lockdep classes with the same key but different names. This is not permitted in lockdep. Unfortunately, I was unaware of that restriction when I wrote the code to debug workqueue problems with lockdep and used the workqueue name as the lockdep class name. This can obviously lead to the problem if the workqueue name is dynamic. This patch solves the problem by always using a constant name for the workqueue's lockdep class, namely either the constant name that was passed in or a string consisting of the variable name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 473980a99316c0e788bca50996375a2815124ce1 added a call to clear the SLB shadow buffer before registering it. Unfortunately this means that we clear out the entries that slb_initialize has previously set in there. On POWER6, the hypervisor uses the SLB shadow buffer when doing partition switches, and that means that after the next partition switch, each non-boot CPU has no SLB entries to map the kernel text and data, which causes it to crash. This fixes it by reverting most of 473980a9 and instead clearing the 3rd entry explicitly in slb_initialize. This fixes the problem that 473980a9 was trying to solve, but without breaking POWER6.
