This adds two sysfs attributes to /sys/bus/ibmebus which can be used to

Echoing the device's location code (as found in the OFDT "ibm,loc-code"

device and cause the appropriate device driver's probe function to be called
on the device.
Likewise, echoing the location code into the "remove" attribute will cause
the device to be removed from the system.
The writes will block until the respective operation has finished and return
an error code if the operation failed.
In addition, two minor tidbits are fixed:
- The fake root device used to provide a common parent for all ebus devices
is now based on device instead of of_device - it had no associated devtree
node. This saves several checks throughout the ebus driver.
- The sysfs attributes are now generated automagically by device_register()
instead of by the ibmebus code, which saves a few compiler warnings about

[POWERPC] zImage: Cleanup and improve zImage entry point
This patch re-organises the way the zImage wrapper code is entered, to
allow more flexibility on platforms with unusual entry conditions.
After this patch, a platform .o file has two options:
1) It can define a _zimage_start, in which case the platform code gets
control from the very beginning of execution. In this case the
platform code is responsible for relocating the zImage if necessary,
clearing the BSS, performing any platform specific initialization, and
finally calling start() to load and enter the kernel.
2) It can define platform_init(). In this case the generic crt0.S
handles initial entry, and calls platform_init() before calling
start(). The signature of platform_init() is changed, however, to
take up to 5 parameters (in r3..r7) as they come from the platform's
initial loader, instead of a fixed set of parameters based on OF's
usage.
When using the generic crt0.S, the platform .o can optionally
supply a custom stack to use, using the BSS_STACK() macro. If this
is not supplied, the crt0.S will assume that the loader has
supplied a usable stack.
In either case, the platform code communicates information to the
generic code (specifically, a PROM pointer for OF systems, and/or an
initrd image address supplied by the bootloader) via a global
structure "loader_info".
In addition the wrapper script is rearranged to ensure that the
platform .o is always linked first. This means that platforms where
the zImage entry point is at a fixed address or offset, rather than
being encoded in the binary header can be supported using option (1).

- The address of the initrd image is now added as device tree
properties, as the kernel expects.
- We only copy a packaged initrd image to a new location if it
is in danger of being clobbered when the kernel moves to its final
location, instead of always.
- By default we decompress the kernel directly to address 0,
instead of requiring it to relocate itself. Platforms (such as OF)
where doing this could clobber still-live firmware data structures can
override the vmlinux_alloc hook to provide an alternate place to
decompress the kernel.

[POWERPC] zImage: Add more flexible gunzip convenience functions
At present, arch/powerpc/boot/main.c includes a gunzip() function
which is a convenient wrapper around zlib. However, it doesn't
conveniently allow decompressing part of an image to one location,
then the remainder to a different address.
This patch adds a new set of more flexible convenience wrappers around
zlib, moving them to their own file, gunzip_util.c, in the process.
These wrappers allow decompressing sections of the compressed image to
different locations. In addition, they transparently handle
uncompressed data, avoiding special case code to handle uncompressed
vmlinux images.
The patch also converts main.c to use the new wrappers, using the new
flexibility to avoid decompressing the vmlinux's ELF header twice as
we did previously. That in turn means we avoid extending our
allocations for the vmlinux to allow space for the extra copy of the

[POWERPC] Allow duplicate lmb_reserve() calls
At present calling lmb_reserve() (and hence lmb_add_region()) twice
for exactly the same memory region will cause strange behaviour.
This makes life difficult when booting from a flat device tree with
memory reserve map. Which regions are automatically reserved by the
kernel has changed over time, so it's quite possible a newer kernel
could attempt to auto-reserve a region which is also explicitly listed
in the device tree's reserve map, leading to trouble.
This patch avoids the problem by making lmb_reserve() ignore a call to
reserve a previously reserved region. It also removes a now redundant
test designed to avoid one specific case of the problem noted above.
At present, this patch deals only with duplicate reservations of an
identical region. Attempting to reserve two different, but
overlapping regions will still cause problems. I might post another
patch later dealing with this case, but I'm avoiding it now since it
is substantially more complicated to deal with, less likely to occur
and more likely to indicate a genuine bug elsewhere if it does occur.

This reverts commit
39d61db0edb34d60b83c5e0d62d0e906578cc707.
The commit was buggy in multiple ways:
- the conversion to ilog2() was incorrect to begin with
- it tested the wrong #defines, so on all architectures but FRV you'd
never see the bug except for constant arguments.
- the new "get_order()" macro used its arguments multiple times, and
didn't even parenthesize them properly
- despite the comments, it was not true that you could use it for
constant initializers, since not all architectures even use the
generic page.h header file.
All of the problems are individually fixable, but it all boils down to:
better just revert it, and re-do it from scratch.
