commit bda4584cd9 ("MIPS: Support CPU topology files in sysfs")
added topology related macros for all MIPS platforms and commit
bbbf6d8768 ("MIPS: NL: Fix nlm_xlp_defconfig build error")
removed most of the contents from mach-netlogic/topology.h.
The netlogic specific topology is not needed anymore, we just need
to setup the package field in current_cpu_data.

The nlm_xlp_defconfig build fails with
./arch/mips/include/asm/mach-netlogic/topology.h:15:0:
error: "topology_core_id" redefined [-Werror]
In file included from include/linux/smp.h:59:0,
[ ...]
from arch/mips/mm/dma-default.c:12:
./arch/mips/include/asm/smp.h:41:0:
note: this is the location of the previous definition
and similar errors.
This is caused by commit bda4584cd9 ("MIPS: Support CPU topology files
in sysfs") which adds the defines to arch/mips/include/asm/smp.h.
Remove the defines from arch/mips/include/asm/mach-netlogic/topology.h
as no longer necessary.

Most IO block offsets have changed in XLP9XX. Update iomap.h to add the
new addresses of different SoC blocks like PIC, SYS, UART etc. that are
needed by the base code.
On XLP9xx, the SoC blocks of other nodes are seen on a PCI bus
corresponding to the node. Update iomap code to reflect this.

Add MSI chip and MSIX chip definitions.
For MSI, we map the link interrupt to a MSI link IRQ which will
do a second level of dispatch based on the MSI status register.
The MSI chip definitions use the MSI enable register to enable
and disable the MSI irqs.
For MSI-X, we split the 32 available MSI-X vectors across the
four PCIe links (8 each). These PIC interrupts generate an IRQ
per link which uses a second level dispatch as well.
The MSI-X chip definition uses the standard functions to enable
and disable interrupts.

Patchwork: http://patchwork.linux-mips.org/patch/6270/
Most supported systems currently hardwire cpu_has_dsp to 0, so we also
can disable support for cpu_has_dsp2 resulting in a slightly smaller
kernel.

Add support for Netlogic's XLP MIPS SoC. This patch adds:
* XLP processor ID in cpu_probe.c and asm/cpu.h
* XLP case to asm/module.h
* CPU_XLP case to mm/tlbex.c
* minor change to r4k cache handling to ignore XLP secondary cache
* XLP cpu overrides to mach-netlogic/cpu-feature-overrides.h
