platforms/embedded6xx is probably going away, and 52xx boards need

To allow arch/powerpc/kernel/crash.c to build on 32-bit we need a
definition of hard_irq_disable(). 32-bit doesn't support the lazy
interrupt disabling mechanism, so on 32-bit hard_irq_disable() is
simply local_irq_disable(). Add a definition for hard_irq_enable()
just for completeness.
This allows (KEXEC=y && PPC32=y) to build again. Broken since
d04c56f73c30a5e593202ecfcf25ed43d42363a2.

"extern inline" generates a warning with -Wmissing-prototypes and I'm
currently working on getting the kernel cleaned up for adding this to
the CFLAGS since it will help us to avoid a nasty class of runtime
errors.
If there are places that really need a forced inline, __always_inline
would be the correct solution.

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.

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
spufs, e.g. as the initial kboot kernel. This requires
that the SPU specific parts of the core dump and the xmon
code depend on CONFIG_SPU_BASE instead of CONFIG_PPC_CELL.

Currently, we only send a sigtrap if the current task is being ptraced.
This is somewhat inconsistant, and it breaks utrace support in fedora.
