Update the file systems in fs/ implementing a delete_inode() callback to
call truncate_inode_pages(). One implementation note: In developing this
patch I put the calls to truncate_inode_pages() at the very top of those
filesystems delete_inode() callbacks in order to retain the previous
behavior. I'm guessing that some of those could probably be optimized.Signed-off-by: Mark Fasheh

Allow file systems supporting ->delete_inode() to call
truncate_inode_pages() on their own. OCFS2 wants this so it can query the
cluster before making a final decision on whether to wipe an inode from
disk or not. In some corner cases an inode marked on the local node via
voting may not actually get orphaned. A good example is node death before
the transaction moving the inode to the orphan dir commits to the journal.
Without this patch, the truncate_inode_pages() call in
generic_delete_inode() would discard valid data for such inodes.During earlier discussion in the 2.6.13 merge plan thread, Christoph
Hellwig indicated that other file systems might also find this useful.IMHO, the best solution would be to just allow ->drop_inode() to do the
cluster query but it seems that would require a substantial reworking of
that section of the code. Assuming it is safe to call write_inode_now() in
ocfs2_delete_inode() for those inodes which won't actually get wiped, this
solution should get us by for now.Trivial testing of this patch (and a related OCFS2 update) has shown this
to avoid the corruption I'm seeing.Signed-off-by: Mark Fasheh

Remove the weird and apparently unnecessary logic in MP_processor_info() which
assumes that the BSP is the first one to run MP_processor_info(). On one of

This makes ACPI_BLACKLIST_YEAR be consistently defined when ACPI is

The pciconfig_iobase, pciconfig_read and pciconfig_write system calls
were only implemented for 32-bit processes; for 64-bit processes they
returned an ENOSYS error. This allows them to be used by 64-bit
processes as well. The X server uses pciconfig_iobase at least, and
this change is necessary to allow a 64-bit X server to work on my G5.Signed-off-by: Paul Mackerras

This patch pulls the PCI-related junk out of struct device_node and
puts it in a separate structure, struct pci_dn. The device_node now
just has a void * pointer in it, which points to a struct pci_dn for
nodes that represent PCI devices. It could potentially be used in
future for device-specific data for other sorts of devices, such as
virtual I/O devices.Signed-off-by: Paul Mackerras

In PPC64 there are number of problems in arch/ppc64/boot/main.c that
prevent a kernel from making use of a large (greater than ~16MB) INITRD.
This is 64 bit architecture and really large INITRD images should be
possible.Simply put the existing code has a fixed reservation (claim) address and
once the kernel plus initrd image are large enough to pass this address
all sorts of bad things occur. The fix is the dynamically establish the
first claim address above the loaded kernel plus initrd (plus some
"padding" and rounding). If PROG_START is defined this will be used as
the minimum safe address - currently known to be 0x01400000 for the
firmwares tested so far.Signed-off-by: Mark Bellon

The earlier commit 8d9273918635f0301368c01b56c03a6f339e8d51
(Consolidate early console and PPCDBG code) broke iSeries because
it caused unregister_console(&udbg_console) to be called
unconditionally. iSeries never registers the udbg_console.This just reverts part of the change.
