The 'linux,boot-cpu' property is obsolete, so remove it from all of the DTS
files and from booting-without-of.txt.  The boot CPU is actually defined in
the device tree header, and U-Boot sets that field.  The device tree compiler
also complains if the property exists.

Getting BenH's new EMAC driver working on 440GP, I found some more
problems in the native mode paths of the new DCR code:
	- dcr_map() is supposed to return a dcr_host_t, but the native
version is a macro that doesn't expand to an expression.  With native
DCRs, dcr_host_t is an empty structure, so we just use a constructor
expression instead.
	- dcr_unmap() uses {} instead of the safer do {} while (0)
idiom to implement a no-op

Here's a fix.

Since the security checks are applied on each read and write of a sysctl file,
just like they are applied when calling sys_sysctl, they are redundant on the
standard VFS constructs.  Since it is difficult to compute the security labels
on the standard VFS constructs we just mark the sysctl inodes in proc private
so selinux won't even bother with them.

Hmmm...turns out to not be quite enough, as the /proc/sys inodes aren't truly
private to the fs, so we can run into them in a variety of security hooks
beyond just the inode hooks, such as security_file_permission (when reading
and writing them via the vfs helpers), security_sb_mount (when mounting other
filesystems on directories in proc like binfmt_misc), and deeper within the
security module itself (as in flush_unauthorized_files upon inheritance across
execve).  So I think we have to add an IS_PRIVATE() guard within SELinux, as
below.  Note however that the use of the private flag here could be confusing,
as these inodes are _not_ private to the fs, are exposed to userspace, and
security modules must implement the sysctl hook to get any access control over
them.

With this change the sysctl inodes can be cached and nothing needs to be done
when removing a sysctl table.

For a cost of 2K code we will save about 4K of static tables (when we remove
de from ctl_table) and 70K in proc_dir_entries that we will not allocate, or
about half that on a 32bit arch.

The speed feels about the same, even though we can now cache the sysctl
dentries :(

We get the core advantage that we don't need to have a 1 to 1 mapping between
ctl table entries and proc files.  Making it possible to have /proc/sys vary
depending on the namespace you are in.  The currently merged namespaces don't
have an issue here but the network namespace under /proc/sys/net needs to have
different directories depending on which network adapters are visible.  By
simply being a cache different directories being visible depending on who you
are is trivial to implement.

The current logic to walk through the list of sysctl table headers is slightly
painful and implement in a way it cannot be used by code outside sysctl.c

I am in the process of implementing a version of the sysctl proc support that
instead of using the proc generic non-caching monster, just uses the existing
sysctl data structure as backing store for building the dcache entries and for
doing directory reads.  To use the existing data structures however I need a
way to get at them.

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name.  Which is
pain for caching and the proc interface never implemented.

I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.

So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

binfmt_misc has a mount point in the middle of the sysctl and that mount point
is created as a proc_generic directory.

Doing it that way gets in the way of cleaning up the sysctl proc support as it
continues the existence of a horrible hack.  So instead simply create the
directory as an ordinary sysctl directory.  At least that removes the magic
special case.
