When pci_assign_all_busses is set, the common code will re-assign all
the bus numbers, which we still need to do one various pmacs, at least
until XFree/XOrg understands PCI domains properly.  However, this
process triggers a bug if during this renumbering, on a given segment, a
P2P bridge not yet renumbered has conflicting downstream bus range with
a P2P bridge just renumbered.  The probing will just behave randomly and
either miss devices, show duplicates, or just lockup in some
circumstances.  This is typically triggered on Apple Xserve G4s who have
at least 2 P2P bridges built-in on the same segment of the first PCI
(non-AGP) domain

The "workaround" we use on pmac that was in my tree for a while but got
"lost" during the big merge a while ago is to offset the bus numbers
between domains by 16.  This avoids the above collision scenario in all
practical cases.

The long term solution of course is to stop renumbering and make sure
that all drivers are domain safe (there may be a couple issue remaining
in the code that matches PCI / OF devices on ppc32) and XFree/XOrg has
to be fixed.

The following code needs to be added to ide_end_drive_cmd(),
since ide_error() calls ide_end_drive_cmd() after ide_dump_status()
has left the registers pointing at the high order part of the LBA.
Using the taskfile ioctl will then lead to hobRegister[] and

I have a Shuttle SN41G2 and the secondary IDE channel alternates between
IRQ 15 (correct) and IRQ 7 (causing failures accessing the DVD+-RW which is
master, no slave and also messing with the parallel port if it is enabled)
on each boot.  This is running ACPI and APIC on 2.6.5, 2.6.7 and 2.6.8. 
dmesg, dmidecode and /proc/acpi/dsdt are all identical (apart from dmesg
printing of IRQ and errors it causes) regardless of whether it decides to
go on 7 or 15.  It is now running the latest BIOS, earlier BIOS did the
same.

Patch written by Ben Woodard.  Sanity checked by Jesse Barnes.
Signed-off-by: Tony Luck <tony.luck@intel.com>

This is the third & hopefully final version of the monster cleanup
patch. It does significant cleanups of the early boot code of the
ppc64 kernel, and begins the long process of cleaning up & splitting
properly the platform support.

It completely reworks the interface between the early code that is
run in the firmware context (prom_init) and the rest of the kernel,
in such a way that will make kexec or static device-tree for embedded
people possible. The early init code can eventually be moved to a
separate link entity, it no longer touches any of the kernel globals,
everything is passed via a single blob of data in memory containing
a flattened version of the device-tree and a memory reserve map.

While doing it, I also cut the ties between pSeries and Powermac. Now,
the kernel config provides a choice between legacy iSeries and
"multiplatform". The later is a set of various supported platform,
each of them beeing a boolean switch, currently defined beeing pSeries
and PowerMac. You can enable both or just one of them. CONFIG_PPC_PSERIES
is now specifically set for IBM pSeries support, you can build a PowerMac
kernel without pSeries support if you which.
The main goal here is to simplify addition of new platform types.

Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

At present, flush_cache_page() is used to handle the case where we
unmap a page or alter the page permissions on the target page with
one exception - access_process_vm().  Based upon the former, the
decision to implement this function is:

        do we need to flush the cache when we unmap or change
        the mapping permissions?

However, kernel/ptrace.c: access_process_vm() also includes into this:

        or we need to ensure cache coherency between the kernel
        and user space mapping of this page.

I argue that the use of flush_cache_page() here in the generic
code is wrong, and if an architecture wishes to use it for this
purpose, it should do so within it's architecture private
implementation of copy_to_user_page() and copy_from_user_page().

So this patch removes the flush_cache_page() from kernel/ptrace.c,
adding it to the arch-specific copy_{to,from}_user_page() where
flush_cache_page is non-empty.
