pm_idle_save resp. pm_idle_old can be NULL when the restore code in acpi_processor_cst_has_changed() resp. cpuidle_uninstall_idle_handler() is called. This can set pm_idle unconditinally to NULL, which causes the kernel to panic when calling pm_idle in the x86 idle code. This was covered by an extra check for !pm_idle in the x86 idle code, which was removed during the x86 idle code refactoring. Instead of restoring the pm_idle check in the x86 code prevent the acpi/cpuidle code to set pm_idle to NULL.

ipwireless: Increase PPP outgoing queue size Increase default size of PPP outgoing queue. Currently set to 1, which means that a packet quickly following another pushed by PPP must wait until hardware actually sends the previous and PPP has to be waken up by ppp_wakeup(). This slows down upstream. Now PPP can push more packets at once which get buffered inside driver and pushed immediatelly to hardware when previous packet is out. Experiments show that size = 10 is quite good for all connection types (GPRS/EDGE/UMTS) and gains 4 KB/sec of upload for UMTS for batch uploads. Need for higher queue size than 10 occures in only < 0.1 % of cases.

Allow the platform data to specify the bus bumber that the new I2C bus will be given. This is to allow the use of the board registration mechanism to specify the new style of I2C device registration which allows boards to provide a list of attached devices. Note, as discussed on the mailing list, we have dropped backwards compatibility of adding an dynamic bus number as it should not affect most boards to have the bus pinned to 0 if they have either not specified platform data for driver. Any board supplying platform data will automatically have the bus_num field set to 0, and anyone who needs the driver on a different bus number can supply platform data to set bus_num.

Put all i/o statistics in struct proc_io_accounting and use inline functions to initialize and increment statistics, removing a lot of single variable assignments.

Piss-poor sysctl registration API strikes again, film at 11... What we really need is _pathname_ required to be present in already registered table, so that kernel could warn about bad order. That's the next target for sysctl stuff (and generally saner and more explicit order of initialization of ipv[46] internals wouldn't hurt either). For the time being, here are full fixups required by ..._rotable() stuff; we make per-net sysctl sets descendents of "ro" one and make sure that sufficient skeleton is there before we start registering per-net sysctls.
