This reverts most of commit 19d36ccdc34f5ed444f8a6af0cbfdb6790eb1177.
The way to DEBUG_RODATA interactions with KPROBES and CPU hotplug is to
just not mark the text as being write-protected in the first place.
Both of those facilities depend on rewriting instructions.Having "helpful" debug facilities that just cause more problem is not
being helpful. It just adds complexity and bugs. Not worth it.Reported-by: Rafael J. Wysocki

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.Signed-off-by: Al Viro

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.Signed-off-by: Christoph Hellwig

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.

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.Signed-off-by: Benjamin Herrenschmidt

This adds a function that tells you if a given kernel virtual address

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".Signed-off-by: Alan Curry

Scan the device tree for i2c devices, check their "compatible" property
against a hard-coded table, and, if found, register with i2c boardinfo.
This provides the infrastructure needed to find i2c devices in the
device tree and register them with the i2c subsystem.This and the following commit let the linkstation work with the new i2c
API and thus fix a regression.Signed-off-by: G. Liakhovetski

The Freescale PCI PHBs actual report back values in the BAR registers
this causes issues in that we try to allocate resources for them
and will get error messages like the following on MPC8544 DS:PCI: Failed to allocate mem resource #1:80000000@0 for 0000:00:00.0

This reverts commit fd6e9d3945ee122eb513ada8b17296d243c1ce5e.
Having #size-cells == 0 in a node indicates that things under the
node aren't directly accessible, and therefore we shouldn't try to
translate addresses for devices under the node into CPU physical
addresses.Some drivers, such as the nvram driver for powermacs, rely on
of_address_to_resource failing if they are called for a node
representing a device whose resources aren't directly accessible
by the CPU. These drivers were broken by commit fd6e9d39,
resulting in the "Lombard" powerbook hanging early in the boot
process.Signed-off-by: Paul Mackerras
