commit fe1668ae5bf0145014c71797febd9ad5670d5d05 causes kernel to oops with

[PATCH] mm: use symbolic names instead of indices for zone initialisation
Arch-independent zone-sizing is using indices instead of symbolic names to
offset within an array related to zones (max_zone_pfns). The unintended
impact is that ZONE_DMA and ZONE_NORMAL is initialised on powerpc instead
of ZONE_DMA and ZONE_HIGHMEM when CONFIG_HIGHMEM is set. As a result, the
the machine fails to boot but will boot with CONFIG_HIGHMEM turned off.
The following patch properly initialises the max_zone_pfns[] array and uses
symbolic names instead of indices in each architecture using
arch-independent zone-sizing. Two users have successfully booted their
powerpcs with it (one an ibook G4). It has also been boot tested on x86,
x86_64, ppc64 and ia64. Please merge for 2.6.19-rc2.

first fix. Additional credit to Johannes Berg and Andreas Schwab for

IB/cm: Send DREP in response to unmatched DREQ
Currently a DREP is only sent in response to a DREQ if a connection
has been found matching the DREQ, and it is in the proper state. Once
a DREP is sent, the local connection moves into timewait. Duplicate
DREQs received while in this state result in re-sending the DREP.
However, it's likely that the local connection will enter and exit
timewait before the remote side times out a lost DREP and resends a DREQ.
To handle this, we send a DREP in response to a DREQ, even if a local
connection is not found. This avoids maintaining disconnected
id's in timewait states for excessively long times, just to handle a
lost DREP.

Enable multiple concurrent connections to the same SRP target:
1) Use port GUID instead of node GUID in the initiator port
identifier. This allows connections to be made from multiple HCA
ports at the same time.
2) Let the user specify the identifier extention when adding the
device. This allows userspace to make multiple connections even
from the same port, if it wants too.
Without this, only one connection can be made from any given HCA, even
if it has multiple ports, because we don't use multi-channel mode, so
targets will only allow one connection from a given initiator port ID.

[POWERPC] Fix secondary CPU startup on old "powersurge" SMP powermacs
On the old "powersurge" SMP powermacs, the second CPU is started up
by sending it an IPI, which has the side effect of stopping the
timebase clock (so the secondary CPU's timebase can be synchronized
with the primary's). The routine that did this used udelay, which
will hang forever when the timebase is stopped, since udelay now spins
until the timebase reaches a certain value.
The end result is that the kernel would hang when bringing up the
second CPU. This fixes it by using a simple loop which just does a
fixed number of iterations to generate the delay. These old systems
were all clocked at around 200 MHz or so, so a fixed number of
iterations is acceptable.
The IDE driver will pick up the PCI IRQ for both channels on Maple
despite the fact that it's in legacy mode. This works around it by
"hiding" the PCI IRQ of the AMD8111 IDE controller when it's configured
in legacy mode on the Maple platform, thus causing the driver to call
pci_get_legacy_ide_irq() which will return the correct interrupts for
both channels.
