CONFIG_HAVE_ARCH_PARSE_SRAT=y
in which case acpi.h defines the acpi_numa_slit_init() and
acpi_numa_processor_affinity_init() methods as a macro.

Currently, fsl_i2c_of_init() uses the order of the I2C adapter nodes in the
device tree to enumerate the I2C adapters. Instead, let's check for the
cell-index property and use it if it exists.
This is handy for device drivers that need to identify the I2C adapters by
specific numbers. The Freescale MPC8610 ASoC V2 sound drivers are an example.

Both the PNP/PCI conflict detection quirk and the PNP system
driver must use the same mechanism to mark resources as disabled.
I think it's best to keep the resource and to keep the type bit
(IORESOURCE_MEM, etc), so that we match the list from firmware
as closely as possible.

On machines with more than one exception level any system register that
might be modified by the "normal" exception level needs to be saved and
restored on taking a higher level exception. We already are saving
and restoring ESR and DEAR.
For critical level add SRR0/1.
For debug level add CSRR0/1 and SRR0/1.
For machine check level add DSRR0/1, CSRR0/1, and SRR0/1.
On FSL Book-E parts we always save/restore the MAS registers for critical,
debug, and machine check level exceptions. On 44x we always save/restore
the MMUCR.
Additionally, we save and restore the ksp_limit since we have to adjust it
for each exception level.

For the additonal exception levels (critical, debug, machine check) on
40x/book-e we were using "static" allocations of the stack in the
associated head.S.
Move to a runtime allocation to make the code a bit easier to read as
we mimic how we handle IRQ stacks. Its also a bit easier to setup the
stack with a "dummy" thread_info in C code.

This MSI driver can be used on 83xx/85xx/86xx board.
In this driver, virtual interrupt host and chip were
setup. There are 256 MSI interrupts in this host, Every 32
MSI interrupts cascaded to one IPIC/MPIC interrupt.
The chip was treated as edge sensitive and some necessary
functions were setup for this chip.
Before using the MSI interrupt, PCI/PCIE device need to
ask for a MSI interrupt in the 256 MSI interrupts. A 256bit
bitmap show which MSI interrupt was used, reserve bit in
the bitmap can be used to force the device use some designate
MSI interrupt in the 256 MSI interrupts. Sometimes this is useful
for testing the all the MSI interrupts. The msi-available-ranges
property in the dts file was used for this purpose.
