Subject: powerpc: Make MPIC honor the "pic-no-reset" device tree property

This property, defined in the Open PIC binding, tells the kernel not to use
the reset bit in the global configuration register.  Additionally, its
presence mandates that only sources which are actually used (i.e. appear in
the device tree) should have their VECPRI bits initialized.

Although, "pic-no-reset" can be used for the same use cases that
"protected-sources" is covering, the "protected-sources" implementation was
left completely intact.  This is a more pragmatic approach as there are
already several existing systems which use protected sources.  If
"pic-no-reset" *and* "protected-sources" are both used, however, then
"pic-no-reset" takes precedence in terms of the init behavior and the
sanity checks done by protected sources will still take place.

Subject: powerpc: Factoring mpic cpu id fetching into a function

The following code snippet:

	unsigned int cpu = 0;
	if (mpic->flags & MPIC_PRIMARY)
		cpu = hard_smp_processor_id();

is seen in several places in the 'mpic.c' code.  This changeset factors
that pattern out into a helper function called 'mpic_processor_id'.

Subject: rapidio: add architecture specific callbacks

This set of patches eliminates RapidIO dependency on PowerPC architecture
and makes it available to other architectures (x86 and MIPS).  It also
enables support of new platform independent RapidIO controllers such as
PCI-to-SRIO and PCI Express-to-SRIO.

This patch:

Extend number of mport callback functions to eliminate direct linking of
architecture specific mport operations.

Subject: rapidio: modify mport ID assignment

Changes mport ID and host destination ID assignment to implement unified
method common to all mport drivers.  Makes "riohdid=" kernel command line
parameter common for all architectures with support for more that one host
destination ID assignment.

Subject: rapidio: remove mport resource reservation from common RIO code

Removes resource reservation from the common sybsystem initialization code
and make it part of mport driver initialization.  This resolves conflict
with resource reservation by device specific mport drivers.

Subject: powerpc: mpic: Cleanup flow type handling

The core irq_set_type() function updates the flow type when the chip
callback returns 0. So setting the type is bogus.

The new core code allows to update the type in irq_data and return
IRQ_SET_MASK_OK_NOCOPY, so the core code will not touch it, except for
setting the IRQ_LEVEL flag.

Retrieve the IRQ_LEVEL information from irq_data which avoids a
redundant sparse irq lookup as well.

The core irq_set_type() function updates the flow type when the chip
callback returns 0. So setting the type is bogus. The core also
updates IRQ_LEVEL.

Use irq_data to get the level type information in the chip functions.

Subject: powerpc/85xx: Don't add disabled PCIe devices

PCIe nodes with the property status="disabled" are not usable and so
avoid adding "disabled" PCIe bridge with the system.

Subject: RapidIO/mpc85xx: fix possible mport registration problems

Fix a possible problem with mport registration left non-cleared after
fsl_rio_setup() exits on link error.  Abort mport initialization if
registration failed.

This patch is applicable to 2.6.39-rc1 only.  The problem does not exist
for earlier versions.
