[PATCH] ppc32/ppc64: cleanup /proc/device-tree

This cleans up the /proc/device-tree representation of the Open Firmware
device-tree on ppc and ppc64.  It does the following things:

 - Workaround an issue in some Apple device-trees where a property may
   exist with the same name as a child node of the parent.  We now
   simply "drop" the property instead of creating duplicate entries in
   /proc with random result...

 - Do not try to chop off the "@0" at the end of a node name whose unit
   address is 0.  This is not useful, inconsistent, and the code was
   buggy and didn't always work anyway.

 - Do not create symlinks for the short name and unit address parts of a
   node.  These were never really used, bloated the memory footprint of
   the device-tree with useless struct proc_dir_entry and their matching
   dentry and inode cache bloat.

This results in smaller code, smaller memory footprint, and a more
accurate view of the tree presented to userland.

[PATCH] ppc64: Fix a device-tree bug on Apple's

Apple's Open Firmware has a funny bug when creating the /cpus nodes

appearing in the full path of the node. This is bogus and
confuses /proc/device-tree badly.

reading the device-tree from Open Firmware. The "name" property is not
modified and still contains the spurrious 0 (it basically contains 0
tailing 0 instead of one) but that shouldn't be a problem.

- Use list_rwsem to avoid slot status change races between disable_slot

- Fixed oopsing in cpci_hp_unregister_bus caused by calling list_del on

- Removed kfree calls in cleanup_slots since release_slot will have

[PATCH] ppc32: Simplified load string emulation error checking

The error checking for emulation of load string instructions was overly
generous and would cause certain valid forms of the instructions to be
treated as illegal.  We drop the range checking since the architecture
allows this to be boundedly undefined.  Tests on CPUs that support these
instructions appear not do cause illegal instruction traps on range errors
and just allow the execution to occur.

doing.
