This allows any secondary CPU thread also to become boot cpu for
POWER5.  The patch is required to solve kdump boot issue when the
kdump kernel is booted with parameter "maxcpus=1".  XICS init code
tries to match the current boot cpu id with "reg" property in each CPU
node in the device tree.  But CPU node is created only for primary
thread CPU ids and "reg" property only reflects primary CPU ids.  So
when a kernel is booted on a secondary cpu thread above condition will
never meet and the default distribution server is left as zero.  This
leads to route the interrupts to CPU 0, but which is not online at
this time.

We use ibm,ppc-interrupt-server#s to check for both primary and
secondary CPU ids.  Accordingly default distribution server value is
initialized from "ibm,ppc-interrupt-gserver#s" property.  We loop
through ibm,ppc-interrupt-gserver#s property to find the global
distribution server from the last entry that matches with boot cpuid.

It's currently not possible to build the default zImage
target if PS3 is the only selected platform. This is
a hack to fall back to building the pseries style
zImage, so the build is successful. This will probably
change in the future, if someone writes a PS3 specific
boot wrapper.
Signed-off-by: NArnd Bergmann <arnd.bergmann@de.ibm.com>

A few code paths need to check whether or not they are running
on the PS3's LV1 hypervisor before making hcalls. This introduces
a new firmware feature bit for this, FW_FEATURE_PS3_LV1.

Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES,
FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time,
which is a bug. The same problem can also happen for (PPC_ISERIES &&
!PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I
introduce a new CONFIG_PPC_NATIVE option that is set when at least
one platform is selected that can run without a hypervisor and then
turns the firmware feature check into a run-time option.

The new cell oprofile support that was recently merged does not
work on hypervisor based platforms like the PS3, therefore make
it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change
if we get oprofile support for PS3.

It may be desireable to build a kernel for cell without
