This replaces the binding for flash chips in booting-without-of.txt
with an clarified and improved version. It also makes
drivers/mtd/maps/physmap_of.c recognize this new binding. Finally it
revises the Ebony device tree source to use the new binding as an
example.Signed-off-by: David Gibson

Previously, the TLB miss handlers assumed that pages above KERNELBASE are
always present and read/write. This assumption is false in the case of
CONFIG_DEBUG_PAGEALLOC.Signed-off-by: Scott Wood

Some firmwares (such as PlanetCore) only provide a base MAC address, and
expect the kernel to set certain bits to generate the addresses for the
other ports. As such, MAC addresses are generated that may not correspond
to actual hardware.Signed-off-by: Scott Wood

1. ft_create_node was returning the internal pointer rather than a phandle.
2. ft_find_device_rel was treating a "top" phandle of NULL as an error,
rather than as the root of the tree. The old, absolute ft_find_device
is removed, and the relative version is renamed to ft_find_device().Signed-off-by: Scott Wood

Remove leftover cruft from ARCH=ppc.

Move pasemi_idle_init() to be a late_initcall instead of being called from
setup_arch(). This way the cpufreq driver has a chance to initialize and

Add printout of some SoC error status registers, and dump the SLB contents
for those machine check events where it makes sense.Since we can't go about and ioremap registers at machine check time,
and we generally want to do as little as possible to print out the
information, pre-build a table of the registers to dump and their address
in the common PCI config space range.Signed-off-by: Olof Johansson

Erratum 5945 causes some of the registers on the PCIe root ports to

The most common match semantic is an exact match based on the device node.
So provide a default implementation that does this, and hook it up if no
match routine is specified.Signed-off-by: Michael Ellerman
Signed-off-by: Paul Mackerras -
Currently if you don't specify a match callback for your irq_host it's
assumed you match everything. This is a kind of opt-out approach, and
turns out to be the exception rather than the rule.So change the semantics to be opt-in, ie. you don't match anything unless
you provide a match callback. This in itself isn't very useful, but will
allow us to provide a default match implementation in a subsequent patch.Signed-off-by: Michael Ellerman

The majority of irq_host implementations (3 out of 4) are associated
with a device_node, and need to stash it somewhere. Rather than having
it somewhere different for each host, add an optional device_node pointer
to the irq_host structure.Signed-off-by: Michael Ellerman

Currently the bootwrapper has implementations of strchr() and
strncmp(), but they're inlines in flatdevtree_env.h, rather than in
string.S with all the rest of the string functions. This moves

Per conversations with BenH, IOMMU virtual merging should no longer

One of the very first things lguest_init() does is a memcpy. On
Athlon/Duron/K7 or CyrixIII/VIA-C3 or Geode GX/LX, this tries to use
MMX.memcpy -> _mmx_memcpy -> kernel_fpu_begin -> clts -> paravirt_ops.clts
But we haven't set paravirt_ops.clts yet, so we do the native version
and crash. The simplest solution is to use __memcpy.Thanks to Michael Rasenberger for the bug report.

With the I/O space rewrite by BenH, the legacy_serial serial_dev_init()
initcall is now called before I/O space is setup, but it's dependent on
it being available.Since there's no way to make dependencies between initcalls, we'll just
have to move it to device_initcall(). Yes, it's suboptimal but I'm not
aware of any better solution at this time, and it fixes a regression
from 2.6.22.Signed-off-by: Olof Johansson

leds: Add missing include for leds.h -
Commit f629307c857c030d5a3dd777fee37c8bb395e171 introduced uses of
kernel_termios_to_user_termios_1 and user_termios_to_kernel_termios_1
on all architectures. However, powerpc, s390, avr32 and frv don't
currently define those functions since their termios struct didn't
need to be changed when the arbitrary baud rate stuff was added, and
thus the kernel won't currently build on those architectures.This adds definitions of kernel_termios_to_user_termios_1 and
user_termios_to_kernel_termios_1 to include/asm-generic/termios.h
which are identical to kernel_termios_to_user_termios and
user_termios_to_kernel_termios respectively. The definitions are the
same because the "old" termios and "new" termios are in fact the same
on these architectures (which are the same ones that use
asm-generic/termios.h).Signed-off-by: Paul Mackerras

Since the ULI1575 has a ISA bus we need to enable the generic ISA dma
support for drivers that might expect it. Without this we get compile

On the root PCI bus, the OBP device tree lists device 3 twice.
Once as 'pm' and once as 'lomp'.Everything goes downhill from there.
Ignore the second instance to workaround this.
