This adds links to the driver and device inside /sys/class/net/ethX for
PowerPC Virtual Ethernet devices.

This fixes a bug where different partitions were assigned the same MAC
address.  Also, according to Anton, gcc 3.5 didn't like our mac_addr_p
gymnastics, so this ends up fixing that as well.

This patch fixes SMP boot on Apple Xserve G5

It is possible to attach a virtual disk to a logical partition on an iSeries
machine so that it is read only to the partition.  This patch allows Linux to
use such virtual disks.

After I sent the recent patch to include/asm-ppc64/io.h which put stronger
barriers in the I/O accessor macros, Paul McKenney pointed out to me that a
writex/outx could still slide out from inside a spinlocked region.  This patch
makes the barriers a bit stronger so that this can't happen.  It means that we
need to use a sync instruction for wmb (a full "heavyweight" sync), since
drivers rely on wmb for ordering between writes to system memory and writes to
a device.

I have left smb_wmb() as a lighter-weight barrier that orders stores, and
doesn't impose an ordering between cacheable and non-cacheable accesses (the
amusingly-named eieio instruction).  I am assuming here that smp_wmb is only
used for ordering stores to system memory so that another cpu will see them in
order.  It can't be used for enforcing any ordering that a device will see,
because it is just a gcc barrier on UP.

This also changes the spinlock/rwlock unlock code to use lwsync ("light-weight
sync") rather than eieio, since eieio doesn't order loads, and we need to
ensure that loads stay inside the spinlocked region.

From: Paul Mackerras <paulus@samba.org>

When I sent the patch to uninline the spinlocks, I inadvertently left out
the change to arch/ppc64/Kconfig which defines the config symbol for
inlining the locks (CONFIG_SPINLINE now).  This patch adds it.  It also
adds a symbol CONFIG_PPC_SPLPAR which enables the code for calling the
hypervisor on shared-processor logically-partitioned system to yield the
physical processor to the lock holder when spinning.  (The code that
depends on this symbol is already present in arch/ppc64/lib/locks.c.)

It turns out we do avoid irq recursion on iseries so remove the workaround.

We check nvram_fetch/nvram_store against -1, so better not make these
unsigned.

Based on feedback from the hardware guys align jiffies and tb_last_stamp.
We update both regularly and there are other read only, heavily accessed
things that share those cachelines.

We need to set MSR_RI in iseries exception prolog.

We were allocating radix tree nodes in the interrupt code with GFP_KERNEL
under a spinlock.  Change it to GFP_ATOMIC.

The patch below moves some declarations from C files into the appropriate
header file in include/asm-ppc (and removes an unused local variable in a
function).

From: Paul Mackerras <paulus@samba.org>

Matt Porter's recent changes broke the compile for non-4xx ppc32 systems,
unfortunately.  I get an error that mfdcr is not defined in
include/asm-ppc/ocp.h when compiling for powermac (reasonable, since the
mfdcr instruction only exists on 4xx processors).  The patch below fixes
it.

This patch fixes the condition where prefetching cache lines beyond a
buffer can cause data corruption on non cache coherent PPCs.  It is a port
of the version that went into 2.4.  From Eugene Surovegin
<ebs@ebshome.net>.

From: Matt Porter <mporter@kernel.crashing.org>

This patch implements/uses __flush_dcache_icache_page() which kmaps on a
Book E part, but keeps the existing behavior on other PowerPCs which can
disable the MMU.

From: Olaf Hering <olh@suse.de>

ext3 as module is not possible in 2.6.6, clear_pages, called from clear_page,
is not exported.

Also, unexport clear_page(), which is an inline.

inode->i_flags should never contain fs-specific flags.  In fact, it doesn't;
the checks against it cause "chattr +T" to be useless for ext[23].  Same bug
was in befs as well.

We already have block number (inode->i_ino), so there is no need to calculate
it from befs_block_run before sb_bread() call (this is what befs_bread_iaddr()
do).

From: "Sergey S. Kostyliov" <rathamahata@php4.ru>

LBD patch merged long time ago, so it is safe to pass u64 block numbers to
sb_bread() when sector_t is large enough.
