[PATCH] pcnet32: use MAC address from prom also on powerpc
The CSR contains garbage after a coldboot on RS/6000.
One some systems (like my 44p 270) the MAC address is all FF,
on others (like my B50) it is ff:ff:ff:fd:ff:6b.
It can eventually be fixed by loading pcnet32, set the interface
into the UP state, rmmod pcnet32 and load it again. But this worked
only on the 270.
Only netbooting after a cold start provides the correct MAC address
via prom and CSR. This makes it very unreliable.
I dont know why the MAC is stored in two different places. Remove
the special case for powerpc, which was added in early 2.4 development.

Hitting BUG_ON() in __alloc_bootmem_core() when there is no free page

cp (compiled with acl support) copies the file, lists the extended
attributes on the old file, copies them all to the new file, and then
exits. However the listxattr() calls were failing with this odd behaviour:
llistxattr("a.out", (nil), 0) = 17
llistxattr("a.out", 0x7fffff8c6cb0, 17) = -1 ERANGE (Numerical result out of
range)
I believe this is a simple problem in the logic used to check the buffer
sizes; if the user sends a buffer the exact size of the data, then its ok
:)

[PATCH] powerpc: remove redundant code in stab init
There's never been a hardware platform that has both pSeries/RPA LPAR
hypervisor and stab (pre-POWER4 segment management). This removes

ppc: Build in all three of powermac, PREP and CHRP support
This reverts commit da0825fd201a03294dbf7f8f030676d608da122c, 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.

powerpc/pseries: Optimize IOMMU setup
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.

Linux v2.6.15-rc5
Hey, for no other reason than the fact that I'll be off-line for a
week.
Of course, I could force everybody to just use git (and when I'm emperor
of the world, don't think I won't!), but it seems some people want to
just test official releases. Even if they are just -rc's.
By the time I'm back, Andrew will have fixed all my bugs, and I'll
release it as 2.6.15 and take all the credit.

Link USB drivers later in the kernel
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.
The link order matters for initcall ordering, and this got broken by
mistake by commit 7586269c0b52970f60bb69fcb86e765fc1d72309 which moved
the USB host controller PCI quirk handling around.

NFS: Fix a few further cache consistency regressions
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.

More change is needed here: sg claims to dirty even pages written from,

the moment just fix the 2.6.15 regression.
