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.

We don't always have lmb available, so make arches provide an
early_init_dt_alloc_memory_arch() to handle the allocation of
memory in the fdt code.
When we don't have lmb.h included, we need asm/page.h for __va.

Currently, we're using u32 for cell values, and hence assuming
host-endian device trees.
As we'd like to support little-endian platforms, use a __be32 for cell
values, and convert in the cell accessors.

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

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.

Borislav Petkov reports issues with duplicate sysfs endpoint files after a
resume from a hibernate. It turns out that the code to support alternate
settings under xHCI has issues when a device with a non-default alternate
setting is reset during the hibernate:

[ 427.916699] Call Trace:
The problem is caused by a mismatch between the USB core's view of the
device state and the USB device and xHCI host's view of the device state.
After the device reset and re-configuration, the device and the xHCI host
think they are using alternate setting 0 of all interfaces. However, the
USB core keeps track of the old state, which may include non-zero
alternate settings. It uses intf->cur_altsetting to keep the endpoint
sysfs files for the old state across the reset.
The bandwidth allocation functions need to know what the xHCI host thinks
the current alternate settings are, so original patch set
intf->cur_altsetting to the alternate setting 0. This caused duplicate
endpoint files to be created.
The solution is to not set intf->cur_altsetting before calling
usb_set_interface() in usb_reset_and_verify_device(). Instead, we add a
new flag to struct usb_interface to tell usb_hcd_alloc_bandwidth() to use
alternate setting 0 as the currently installed alternate setting.
