Create a low-level synchronous implementation suitable for use
by the early boot platform code or other places where the
asynchronous driver isn't useable. This also exports the locks
used by the real driver to avoid collisions.
Use this new implementation to properly setup the clock chip
at boot on Apple latest laptops

add support for newer laptops and G5 desktops

move drivers/macintosh/nvram.c to drivers/char/generic_nvram.c,
update platform hooks,
fix powermac nvram driver for newer machines

especially related to the use of the btext early debug text
engine

It would fail to properly release the resource if taken over
by the macio device resource hierarchy. This could still use
some locking, but the io resource lock isn't exported

Without this, page aging is broken on ppc32

Another processor could be walking the page table in the middle of the
PTE page to be freeded. Synchronize with hash_page using the lock.

Add a fix fox machines that don't have HW timebase sync facility

used on machines that don't have a HW facility (or we don't drive
it yet like G5s)

contains a hack that is unfixable at the moment for getting the
IO base which is hard coded to bus number 0 (AGP on earlier machines).
We work around this by passing the IO base of bus 0xf0 when asked
for bus 0 in pciconfig_iobase on those machines. Bus 0 is the HT
root and has no IOs, so that is safe.

We no longer modify the device tree, we use an initdata static
array instead.

TI controller, add some for fixing up ATA & SATA controllers (switch normal
ATA to fully native mode and disable unused function on G5 K2 SATA)

Now that Al Viro fixed cramfs, it works beautifully as an initrd
filesystem.

So finally plumb it in.

I've been chasing a weird SELinux bug which shows up mostly when doing
installs of a dev-* rpm (ie. creating and overwriting lots of block
device inodes), but which I've also seen when doing mkinitrd.

It turned out not to be an SELinux problem at all, but a core VFS
S_ISBLK bug.  It seems that SELinux simply widens the race window.

The code at fault is fs/fs-writeback.c:__mark_inode_dirty():

		/*
		 * Only add valid (hashed) inodes to the superblock's
		 * dirty list.  Add blockdev inodes as well.
		 */
		if (!S_ISBLK(inode->i_mode)) {
			if (hlist_unhashed(&inode->i_hash))
				goto out;
			if (inode->i_state & (I_FREEING|I_CLEAR))
				goto out;
		}

The "I_FREEING|I_CLEAR" condition was added after the ISBLK/unhashed
tests were already in the source, but I can't see any reason why we'd
want the I_FREEING test not to apply to block devices.  And indeed, this
results in all sorts of inode list corruptions.  Simply moving the
I_FREEING|I_CLEAR test out of the protection of the S_ISBLK() condition
fixes things entirely.

The existing 2.6 kernel will reliably fail on me in about 2 seconds once
"rpm -Uvh --force dev*.rpm" starts its actual installation of the new
inodes.  With the patch below I can't reproduce it at all.

The #include is the part of this patch that matters, so the #ifdef below
works.

The rest of the patch removes gratuitous duplication due to some strange
aversion to concision in the presence of #ifdef, the kind that is all too
common, utterly pointless, and error prone.
