8545cd2011 [POWERPC] Remove unused inclusion of linux/ide.h
Remove unneeded inclusion of linux/ide.h
It does not compile with CONFIG_BLOCK=n.

Remove asm/ide.h from ksyms file, it gets included earlier via
linux/ide.h.

Compile tested with all defconfig files.

e51b85dcf5 [POWERPC] PMU LED whitelisting of PowerMac 7,2 and 7,3
This allows the PMU LED on both a PowerMac 7,2 (Dual G5 2.0GHz, June 2003)
and a PowerMac 7,3 (Dual G5 2.0GHz, June 2004) to be controlled.
The physical LED is never off, unlike an iBook/PowerBook LED.
It is rather dim ("off") or very bright ("on").

3af82a8b00 [POWERPC] Clean up zImage handling of the command line
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.

27fbaa9702 [POWERPC] Add device tree utility functions to zImage
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.

569975591c [POWERPC] DMA 4GB boundary protection
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.

61e8b858ab EHCI: fix remote wakeup regression in 2.6.21-rc
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.

76ca1af10e ide: ugly messages trying to open CD drive with no media present
I get the following error messages when trying to open a CD device
(specifically, the Teac CD-ROM CD-224E) that has no media present:

hda: packet command error: status=3D0x51 { DriveReady SeekComplete Error }
hda: packet command error: error=3D0x54 { AbortedCommand LastFailedSense=0x05 }
ide: failed opcode was: unknown

This happens when a "start stop unit" command (0x1b 0 0 0 3 0 0 0 0 0)
is sent to the drive to try to close the CD-ROM tray, but this drive
doesn't have that capability (it's a slim portable-type CD-ROM), so it
reports sense key 5 (illegal request) with asc/ascq 24/0.  This is
exactly how SFF8090i says it should respond.

But ide-cd.c (in cdrom_decode_status() ) just sees sense key 5 and spews
out an error.  It then goes on to request sense data, and
cdrom_log_sense() understands this error and doesn't log it.

The patch, for kernel 2.6.20.4, suppresses this error message.

23450319e2 ide: correctly prevent IDE timer expiry function to run if request was already handled
It is possible for the timer expiry function to run even though the
request has already been handled: ide_timer_expiry() only checks that
the handler is not NULL, but it is possible that we have handled a
request (thus clearing the handler) and then started a new request
(thus starting the timer again, and setting a handler). 

A simple way to exhibit this is to set the DMA timeout to 1 jiffy and
run dd: The kernel will panic after a few minutes because
ide_timer_expiry() tries to add a timer when it's already active.

To fix this, we simply add a request generation count that gets
incremented at every interrupt, and check in ide_timer_expiry() that
we have not already handled a new interrupt before running the expiry
function.

6371ea3d48 IPoIB/cm: Fix DMA direction typo
Receive buffers need to be mapped with DMA_FROM_DEVICE.  Incorrectly
mapping with DMA_TO_DEVICE causes a hard lock on ppc64 machines with
an IOMMU.

ae6ead4623 [PATCH] zd1211rw: Reject AL2230S devices
zd1211rw currently detects AL2230S-based devices as AL2230, and hence
programs the RF incorrectly. Transmit silently fails on this
misconfiguration.

After this patch, AL2230S devices are rejected with an error message, to
avoid any confusion with an apparent driver bug.

52ea0718ea [AGPGART] intel_agp: fix G965 GTT size detect
On G965, I810_PGETBL_CTL is a mmio offset, but we wrongly take it
as pci config space offset in detecting GTT size. This one line patch
fixs this.

15d33c070d [TCP]: slow_start_after_idle should influence cwnd validation too
For the cases that slow_start_after_idle are meant to deal
with, it is almost a certainty that the congestion window
tests will think the connection is application limited and
we'll thus decrease the cwnd there too.  This defeats the
whole point of setting slow_start_after_idle to zero.

So test it there too.

We do not cancel out the entire tcp_cwnd_validate() function
so that if the sysctl is changed we still have the validation
state maintained.
