Interrupt controllers' hooks are executed in the atomic context, so
they are not permitted to sleep (with RT kernels non-raw spinlocks are
sleepable). So, gef_pic_lock has to be a real (non-sleepable) spinlock.

Anton's commit enabling the use of the lwsync fixup mechanism on 64-bit
breaks modules. The lwsync fixup section uses .long instead of the
FTR_ENTRY_OFFSET macro used by other fixups sections, and thus will
generate 32-bit relocations that our module loader cannot resolve.
This changes it to use the same type as other feature sections.
Note however that we might want to consider using 32-bit for all the
feature fixup offsets and add support for R_PPC_REL32 to module_64.c
instead as that would reduce the size of the kernel image. I'll leave
that as an exercise for the reader for now...

Both allnodes and devtree_lock are defined in common code. The
extern declaration should be in the common header too so that the
compiler can type check. allnodes is already in of.h, but
devtree_lock should be declared there too.
This patch removes the SPARC declarations and uses decls in of.h instead.

Commit e22f628395432b967f2f505858c64450f7835365 introduced a build
breakage for ARM devtree work: the THIS_MODULE macro was added, but we
don't have module.h
This change adds the necessary #include to get THIS_MODULE defined.
While we could just replace it with NULL (PROC_FS is a bool, not a
tristate), using THIS_MODULE will prevent unexpected breakage if we
ever do compile this as a module.

Currently when processing flattened device trees, the kernel expects
the phandle in a property called "linux,phandle". The ePAPR spec -
not being Linux specific - instead requires phandles to be encoded in
a property named simply "phandle". This patch makes the kernel accept
either form when unflattening the device tree.

Properties in the device tree are specified as big-endian. At present,
the only platforms to support device trees are also big-endian, so we've
been acessing the properties as raw values.
We'd like to add device tree support to little-endian platforms too, so
add endian conversion to the sites where we access property values in
the common of code.
Compiled on powerpc (ppc44x_defconfig & ppc64_defconfig) and arm (fdt
support only for now).

At present, the fdt code sets the kernel-wide initrd_start and
initrd_end variables when parsing /chosen. On ARM, we only set these
once the bootmem has been reserved.
This change adds an arch hook to setup the initrd from the device
tree:
void early_init_dt_setup_initrd_arch(unsigned long start,
unsigned long end);
The arch-specific code can then setup the initrd however it likes.
Compiled on powerpc, with CONFIG_BLK_DEV_INITRD=y and =n.

We only need set_node_proc_entry in proc_devtree.c, so move it there.
This fixes the !HAVE_ARCH_DEVTREE_FIXUPS build, as we can't make make
the definition in linux/of.h conditional on this #define (definitions in
asm/prom.h can't be exposed to linux/of.h, due to the enforced #include

Microblaze only has one CPU, it isn't SMP at all. early_init_dt_scan_cpus()

In struct device_node, the phandle is named 'linux_phandle' for PowerPC
and MicroBlaze, and 'node' for SPARC. There is no good reason for the
difference, it is just an artifact of the code diverging over a couple
of years. This patch renames both to simply .phandle.
Note: the .node also existed in PowerPC/MicroBlaze, but the only user
seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't
look like the assignment between .linux_phandle and .node is
significantly different enough to warrant the separate code paths
unless ibm,phandle properties actually appear in Apple device trees.
I think it is safe to eliminate the old .node property and use
phandle everywhere.

Special case of of_read_ulong() was defined for PPC32 to toss away
all but the last 32 bits when a large number value was read, and the
'normal' version for ppc64 just #defined of_read_ulong to of_read_number
which causes compiler warnings on MicroBlaze and other 32 bit
architectures because it returns a u64 instead of a ulong.
This patch fixes the problem by defining a common implementation of
of_read_ulong() that works everywhere.
