ip_conntrack_flush() used to be part of ip_conntrack_cleanup(), which needs
to drop _all_ references on module unload. Table flushed using ctnetlink
just needs to clean the table and doesn't need to flush the event cache or
wait for any references attached to skbs. Move everything but pure table
flushing back to ip_conntrack_cleanup().

This reverts commit da0825fd20, making
it so that if you select CONFIG_PPC_MULTIPLATFORM you get support
for PMAC, PREP and CHRP built in.
The reason for not allowing PMAC, PREP and CHRP to be selected
individually for ARCH=ppc is that there is too much interdependency
between them in the platform support code. For example, CHRP uses
the PMAC nvram code.
Configuring with ARCH=powerpc does allow you to select support for
PMAC and CHRP separately. Support for PREP is not there yet but
should be there soon.

The previous commit will use the page-at-a-time hypervisor call for
setting up IOMMU entries when we are using 64k pages and setting up
one 64k page, even though that means 16 calls to the hypervisor, since
the hypervisor still works on 4k pages. This optimizes this case by
using the multi-page IOMMU setup hypervisor call instead.

We want to link the "regular" SCSI drivers before the USB storage
driver, since historically we've always detected internal SCSI disks
before the external USB storage modules.

Steve Dickson writes:
Doing the following:
1. On server:
$ mkdir ~/t
$ echo Hello > ~/t/tmp
2. On client, wait for a string to appear in this file:
$ until grep -q foo t/tmp ; do echo -n . ; sleep 1 ; done
3. On server, create a *new* file with the same name containing that
string:
$ mv ~/t/tmp ~/t/tmp.old; echo foo > ~/t/tmp
will show how the client will never (and I mean never ;-) ) see
the updated file.
The problem is that we do not update nfsi->cache_change_attribute when the
file changes on the server (we only update it when our client makes the
changes). This again means that functions like nfs_check_verifier() will
fail to register when the parent directory has changed and should trigger
a dentry lookup revalidation.

With IGMP version 1 and 2 it is possible to inject a unicast

reports sent later by the router.
The fix is to only accept the report if is was sent to a

2.6.15-rc1 made sg's st_unmap_user_pages and st's sgl_unmap_user_pages
BUG on a PageReserved page. But that's wrong: they could be unmapping
the ZERO_PAGE, which is marked PG_reserved; and perhaps others (while
get_user_pages is still permitted on VM_PFNMAP areas - that may change).
More change is needed here: sg claims to dirty even pages written from,
and st claims not to dirty even pages read into; and SetPageDirty is not
adequate for this nowadays. Fixes to those follow in a later patch: for
the moment just fix the 2.6.15 regression.
