Lifted from http://bugzilla.kernel.org/show_bug.cgi?id=8182
Steps to reproduce:
- Boot an Ocotea board with the mainline 2.6.20.1 kernel.
- Create an /etc/ntp.conf file with at least one NTP server and iburst mode set.
- Issue the command "ntpd -g".
- Wait about two minutes.
- Verify ntpd's status via "ntpq -pn" and by looking in /var/log/ntp.
This fixes this problem by adjusting the expected clock frequency.

There is no reason to yield the CPU in spu_yield - if the backing

This cleans up how the zImage code manipulates the kernel
command line. Notable improvements from the old handling:
- Command line manipulation is consolidated into a new
prep_cmdline() function, rather than being scattered across start()
and some helper functions
- Less stack space use: we use just a single global command
line buffer, which can be initialized by an external tool as before,
we no longer need another command line sized buffer on the stack.
- Easier to support platforms whose firmware passes a
commandline, but not a device tree. Platform code can now point new
loader_info fields to the firmware's command line, rather than having
to do early manipulation of the /chosen bootargs property which may
then be rewritten again by the core.

This patch adds a library of useful device tree manipulation functions
to the zImage library, for use by platform code. These functions are
based on the hooks already in dt_ops, so they're not dependent on a
particular device tree implementation. This patch also slightly
streamlines the code in main.c using these new functions.
This is a consolidation of my work in this area with Scott Wood's
patches to a very similar end.

There are many adapters which cannot handle DMAing across any 4 GB
boundary. For instance, the latest Emulex adapters.
This normally is not an issue as firmware gives dma-windows under
4gigs. However, some of the new System-P boxes have dma-windows above
4gigs, and this present a problem.
During initialization of the IOMMU tables, the last entry at each 4GB
boundary is marked as used. Thus no mappings can cross the boundary.
If a table ends at a 4GB boundary, the entry is not marked as used.
A boot option to remove this 4GB protection is given w/ protect4gb=off.
This exposes the potential issue for driver and hardware development
purposes.

There is one significant difference between the behavior of root hubs
(as embodied in host controller hardware) and external hubs: When a
remote-wakeup signal is received, an external hub sends an interrupt
message at the _end_ of the resume sequence but a root hub generates
and interrupt at the _beginning_ of the resume sequence. The host
system must poll for the end of the sequence.
When ehci-hcd was converted to interrupt-driven operation instead of
using polling, the remaining need for this particular poll was
overlooked. This patch (as894) fixes the problem.
