This adds some initial support for the latest model of iBook G4 (still
need some work on the clock chip at least and some radeonfb updates that
I'll send later along with other fixes for this driver). 

It also removes a useless delay and fixes detection of the airport card
on the "Windtunnel" class desktop G4 machines.

Those were missing from ppc32, please apply.

Heh, I moved 6 month ago, time to update CREDITS ;)

This cleans up the code used to initialize the 970 CPU.

More specifically, it adds support for the 970FX, makes sure we don't
touch registers we aren't supposed to when running in LPAR mode, and
stop blindly zeroing out HID4 and HID5, we just clear the bits we really
want clear in there and leave the rest to the firmware.

During mqueue_get_inode(), it's possible that kmalloc() of the
info->messages array will fail.  This failure mode will cause the
queues_count to be (incorrectly) decremented twice.  This patch uses
info->messages on mqueue_delete_inode() to determine whether the
mqueue was every truly created, and hence proper accounting is needed
on destruction.

Patch from Bjorn Helgaas

This adds efi_uart_console_only() so we can default to using a serial
console if the EFI console path only contains UARTs.

Patch from Alex Williamson

Here's a trivial patch that makes 8250_hcdp setup the correct flags
when IRQ sharing is enabled for serial ports.

The HCDP table tells us if the device is a PCI UART.  We can use this
to set the shared interrupt flag as well as program the interrupt with
the correct polarity/trigger (should get rid of "changing vector <x>
from IO-SAPIC-edge to IO-SAPIC-level" messages at bootup).  This also
allows non-PCI UARTs to be left un-shareable, which is likely much
more safe (edge triggered).

The bit that I'm keying on is still part of the older 1.0a HCDP spec,
so should be implemented (it was on all the boxes I tested).  If
there's firmware out there that doesn't set this bit or the interrupt
supported flag, the HCDP UART may run in polling mode, but should
still be functional.

Patch from Daniel Ritz.

This patch clears an almost undocumented EnE specific test register
that makes sound on RME Hammerfall DSP Carbus work...should even work
after suspend.

This fixes a potential oops/use after free bug, and removes an unused
variable warning.

From: <Andries.Brouwer@cwi.nl>

In the old days the printk log buffer had a constant size, and dmesg asked
for the 4096, later 8192, later 16384 bytes in there.  These days the
printk log buffer has variable size, and it is not easy for dmesg to do the
right thing, especially when doing a "read and clear".  The patch below
adds a syslog subfuntion that reports the buffer size.

Move error handling to capture all three possible error conditions on
sending to a full queue.  Without this fix any unprivileged user can
leak arbitrary amounts of kernel memory.

txAbortCommit is broken and fixing it makes it equivalent to txAbort,
so get rid of it and use txAbort instead.

Get a reference count on the the sleeper, so that
it can't possibly go away before we've sent it the
wakeup event.

Remove two layers of the fossil record from comments on add_to_page_cache:
2.6.6 moves swapcache handling away, and we long ago stopped masking flags.

Old bug noone seems to have hit, but mremap's pte_unmap dst might be
NULL: would get preempt count wrong even when not DEBUG_HIGHMEM.

This fixes booting on some PPC32 machines, notably CHRP and powermac
machines.  This is a modified version of Tom Rini's patch that addresses
the concerns I had with it.

The problem was that the linker script was getting included in the list
of things that got put together to make some of the sorts of bootable
images that we produce.  This removes ld.script in cases where it wasn't
appropriate and changes the rules in others so that although we have the
dependency on ld.script, it doesn't get included in the list of things
to link.

On PPC64, when we prepare segments below 4G for use with hugepages, we
need to flush their entries from the SLB, in case SLB entries
specifying normal pages were already present.

Previously we did that by flushing the entire SLB, the patch below
changes this to individually flush each necessary segment with slbie.
The new version may well be slightly faster, but the real reason for
it is so that this code path doesn't need to be changed to reinstate
any bolted SLB entries, if we add them.  The existing version has
already caused problems (read, crashes) when combined with some
patches that add bolted SLB entries.

cancel_delayed_work() forgets to clear the workqueue's pending flag.  This
makes the workqueue appear to be permanently busy, so any subsequent attempts
to use it will fail.

The existing allocator is first-fit with wraparound.  This allows
a large number of small holes to accumulate in the early part of the
region, leading to heavy fragmentation.  This adjusts the algorithm
to rescan the region when smaller sizes are requested, reducing
early fragmentation.

Previously num_physpages only took into consideration low memory.
Since nr_free_pages returned something much larger, the caches
init would oops.
