__end_that_request_first might modify the bv_offset and bv_len if the
segment was partially completed.  The bio-read-bounce-back code should use
the unmodified bv_offset when copying the segment data:

sysrq-o is supposed to power off the machine.  But if it calls into ACPI (at
least) it does lots of sleepy things, so we best not do this from interrupt
context.

This patch updates the g5_defconfig on ppc64, running it through oldconfig

This patch (hopefully) addresses concerns Christoph Hellwig had with the
virtual disk probing code.

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

iSeries HyperVisor is doing some evilery when inserting PTEs that I didn't
properly account for when rewriting that code, causing iSeries box to blow
up regulary.

address_spaces have a `dirtied_when' jiffies field which records the time at
which the mapping was first dirtied.  This is used for the periodic writeback
(kupdate) function.  It is also used to prevent livelocks in the writeback
code: don't try to write back objects which were dirtied after
sync_sb_inodes() was called.

It used to be the case that dirtied_when == 0 had magical properties, so
there is code in there which avoids accidentally setting dirtied_when to zero
at jiffy wrap time.  We just set it to jiffies|1.

Unfortunately, jiffies|1 is in the future.  So under some rare timing
circumstances (inode dirtied within one jiffy of umount) the livelock
avoidance code in sync_sb_inodes() can accidentally trigger and we fail to
write an inode out, resulting in filesytem corruption on ext2-style
filesystems.  Normally, nobody dirties a file within a millisecond of umount,
so it was not noticed.

It is no longer the case that (address_space.dirtied_when == 0) has special
meaning, so we can just remove all that code and fix the bug.

This fixes the PowerPC Virtual Ethernet driver that got broken by the
recent ppc64 iommu patch...

This patch seems to have been forgotten about, so here it is again,
this time against 2.6.4-rc1.  This really needs to be send upstream,
though I don't know where we got to with this one.  Maybe we should
put it in akpm's tree for a while?

It's essentially more of the "don't deadlock if you pull out a
PCMCIA network card and it's currently configured up" patch which
went in recently for PCMCIA NIC cards.

Note that hp100 in 2.6.4-rc1 is still broken wrt EISA probing, since
it lacks the terminating entry in the EISA ID list. This one-liner
should take care of random crashes that are often reported to LKML :

To hotplug-remove virtual devices, we need vio_find_node() so we have a
pointer to pass to vio_unregister_device().

vio_dev->unit_address only holds 32 bits of information anyways, so no
need for 64-bit field.

Here's a much better version.  The real bug was of course that the
get_user/put_user for data_direction were transposed.

This patch also fixes the translation of "quiet" and "timeout" to be
safer and clearer (instead of memcpying them as two ints and knowing
that "quiet" is first and assuming that "compat_int_t" is always the
same as the native "int", the code now handles them explicitly).

We should use "access_ok()" and __get_user/__put_user to generate better
code for this, but it's not performance-critical, so we don't care.
Some other day, perhaps.

Previous Kconfig change was incorrect, this is a better one.

This part of the patch seems to have been lost (root_hydra_dev is no more):

The SA1111 appears to re-trigger an interrupt immediately following
a successful interrupt, despite no interrupt actually pending.

in our error handling thread callback.

This also exports scsi_finish_command in the SCSI layer.

Thanks much to James Bottomley and his patience, as this solution
was figured out.

Maurice van der Stee noted that he got an oops on a HPFS filesystem when
saving an edited file..

This fixes it.  That, BTW, means that *nobody* had ever tried to use
hpfs r/w since 2.5.3-pre3.
