[POWERPC] spufs: fix MFC command queue purge

static inline void wait_purge_complete(struct spu_state *csa, struct
       spu *spu)

    struct spu_priv2 __iomem *priv2 = spu->priv2;

This will exit as soon as _one_ of the 2 bits that compose
MFC_CNTL_PURGE_DMA_COMPLETE is set, and one of them happens to be
"purge in progress"...  which means that we'll happily continue

[POWERPC] kdump: Reserve the existing TCE mappings left by the first kernel

During kdump boot, noticed some machines checkstop on dma protection
fault for ongoing DMA left in the first kernel. Instead of initializing
TCE entries in iommu_init() for the kdump boot, this patch fixes this
issue by walking through the each TCE table and checks whether the
entries are in use by the first kernel. If so, reserve those entries by
setting the corresponding bit in tbl->it_map such that these entries
will not be available for the kdump boot.

However it could be possible that all TCE entries might be used up due
to the driver bug that does continuous mapping. My observation is around
1700 TCE  entries are used on some systems (Ex: P4) at some point of
time during kdump boot and saving dump (either write into the disk or
sending to remote machine). Hence, this patch will make sure that
minimum of 2048 entries will be available such that kdump boot could be
successful in some cases.

Revert "[PATCH] kthread: update loop.c to use kthread"

This reverts commit c7b2eff059fcc2d1b7085ee3d84b79fd657a537b.

Hugh Dickins explains:

 "It seems too little tested: "losetup -d /dev/loop0" fails with
  EINVAL because nothing sets lo_thread; but even when you patch
  loop_thread() to set lo->lo_thread = current, it can't survive
  more than a few dozen iterations of the loop below (with a tmpfs
  mounted on /tst):

j=0
cp /dev/zero /tst
while :
do
    let j=j+1
    echo "Doing pass $j"
    losetup /dev/loop0 /tst/zero
    mkfs -t ext2 -b 1024 /dev/loop0 >/dev/null 2>&1
    mount -t ext2 /dev/loop0 /mnt
    umount /mnt
    losetup -d /dev/loop0
done

  it collapses with failed ioctl then BUG_ON(!bio).

  I think the original lo_done completion was more subtle and safe
  than the kthread conversion has allowed for."
