b2788965ba MIPS: XLR, XLS: Add comment for smp setup 
It seems that BSP could be setup twice, but the nlm_cpu_ready array is only
set for ASPs in smpboot.S, not including BSP.

39ad56805a MIPS: Netlogic: Specify architecture CFLAGS 
Use -march=xlr if available, otherwise fallback to mips64. This allows
us to support compilation with MIPS toolchains which are not customized
for XLR.

[ralf@linux-mips.org: And more importantly it works around a gas bug in
binutils 2.21 which otherwise may result in an assertion failure building
arch/mips/kernel/genex.S.  See
http://sourceware.org/bugzilla/show_bug.cgi?id=12915 for details.]

b8ecf341f1 MIPS: Do not use EXTRA_CFLAGS 
Usage of these flags has been deprecated for nearly 4 years by:

    commit f77bf01425
    Author: Sam Ravnborg <sam@neptun.(none)>
    Date:   Mon Oct 15 22:25:06 2007 +0200

        kbuild: introduce ccflags-y, asflags-y and ldflags-y

Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command
line use. By default, gmake(1) do not override command line setting, so this is
likely to result in build failure or unexpected behavior.

Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

39263eeb44 MIPS: Netlogic: SMP fixes for XLR/XLS platform code. 
Fix few issues in the Netlogic code:
- Use handle_percpu_irq to handle per-cpu interrupts
- Remove unused function nlm_common_ipi_handler()
- Call scheduler_ipi() on SMP_RESCHEDULE_YOURSELF
- Enable interrupts in nlm_smp_finish()

9b130f8004 MIPS: XLR, XLS: Add PCI support. 
Adds pci/pci-xlr.c to support for XLR PCI/PCI-X interface and XLS PCIe
interface.
