2007-07-26cyclone.c: silly use of volatile, __iomem fixesAl Viro
u32* volatile cyclone_timer means volatile auto pointer to u32, which is clearly not what had been intended (we never even take the address of that variable, let alone pass it to something that could change it behind our back). u32 volatile * is what the authors apparently wanted to say, but in reality we don't need that qualifier there at all - it's (properly) only passed to iomem helpers which takes care of that stuff just fine.

2007-07-26ip6_tunnel - endianness annotationsAl Viro
Convert rel_info to host-endian before calling ip6_tnl_err(). The things become much more straightforward that way. The key observation (and the reason why that code actually worked) is that after ip6_tnl_err() we either immediately bailed out or had rel_info set to 0 or had it set to host-endian and guaranteed to hit (rel_type == ICMP_DEST_UNREACH && rel_code == ICMP_FRAG_NEEDED) case. So inconsistent endianness didn't really lead to bugs, but it had been subtle and prone to breakage. New variant is saner and obviously safe.

2007-07-26[PATCH] sched: update Documentation/sched-stats.txtJoachim Deguara
While learning about schedstats I found that the documentation in the tree is old. I updated it and found some interesting stuff like schedstats version 14 is the same as version and version 13 never saw a kernel release! Also there are 6 fields in the current schedstats that are not used anymore. Nick had made them irrelevant in commit 476d139c218e44e045e4bc6d4cc02b010b343939 but never removed them.

2007-07-26[POWERPC] spusched: Fix initial timeslice calculationChristoph Hellwig
Currently we calculate the first timeslice for every context incorrectly - alloc_spu_context calls spu_set_timeslice before we set ctx->prio so we always calculate the longest possible timeslice for the lowest possible priority. This patch makes sure to update the schedule-related fields before calculating the timeslice and also makes sure we update the timeslice for a non-running context when entering spu_run so a priority change affects the context as soon as possible.

2007-07-26[POWERPC] spufs: Fix incorrect initialization of cbe_spu_info.spusMasato Noguchi
We currently initialize cbe_spu_info[].spus in both init_spu_base and spu_sched_init. The initialise in spu_sched_init clears the SPU list, so we end up with no physical SPUs. Because of this, the spu_run syscall will block forever. This change removes the unnecessary initialization in spu_sched_init.

2007-07-26[POWERPC] Make pci_iounmap actually unmap thingsBenjamin Herrenschmidt
This patch uses the newly added functions for testing if an address is an ISA or PCI IO port to properly unmap things in pci_iounmap that aren't such ports. Without that, drivers using the iomap API will never actually unmap resources, which on IBM server machines will prevent hot-unplug of the corresponding HW adapters.

2007-07-26[POWERPC] Fix Pegasos keyboard detectionAlan Curry
As of 2.6.22 the kernel doesn't recognize the i8042 keyboard/mouse controller on the PegasosPPC. This is because of a feature/bug in the OF device tree: the "device_type" attribute is an empty string instead of "8042" as the kernel expects. This adds a secondary detection which looks for a device whose *name* is "8042" if there is no device whose *type* is "8042".
