This reverts commit 59287c0913cc9a6c75712a775f6c1c1ef418ef3b.

Hugh Dickins reports that it causes random failures on x86 with SuSE
10.2, and points out

"Isn't that randomization, anywhere from 0x10000 to ELF_ET_DYN_BASE,
sure to place the ET_DYN from time to time just where the comment
says it's trying to avoid? I assume that somehow results in the error
reported."

(where the comment in question is the existing comment in the source
code about mmap/brk clashes).

On ia64, the various functions that make up cn_proc.c cause kernel
unaligned access errors.

If you are using these, for example, to get notification about all tasks
forking and exiting, you get multiple unaligned access errors per process.

Use put_unaligned() in the appropriate palces to fix this.

This patch gets the Kyocera FS-820 working with cups 1.2 via usb again. It
adds the printer to the list of "quirky" printers. The printer seems not
answer to ID requests some seconds after plugging in. Patch is based on
linux-2.6.19.1.

Background:
As far as I could see (strace, usbmon), the Kyocera FS-820 answers to ID
requests only a few seconds after plugging it in. This applies to detecting
it with cups and is also true for the printing itself, which is initiated
with an ID request. Since I have little usb knowledge, maybe someone can
interpret the data, especially the fist bulk transfer - why request 8192
bytes? This is the second version of the patch.

I have a Marvell board which has the same i2c hw block than mv64xxx, so
I'm trying to use i2c-mv64xxx driver.

But I get the following random oops at boot:

The oops is caused by a spurious interrupt that occurs when request_irq
is called. mv64xxx_i2c_fsm() tries to read drv_data->msg, which is NULL.

I noticed that hardware init is done after requesting irq. Thus any
pending irq from previous hardware usage may cause this.

The following patch fixes it:

[AGPGART] fix detection of aperture size versus GTT size on G965
[AGPGART] Remove unnecessary flushes when inserting and removing pages.
[AGPGART] K8M890 support for amd-k8.

Looks like this is the problem, which point Al Viro some time ago:

ufs's get_block callback allocates 16k of disk at a time, and links that
entire 16k into the file's metadata. But because get_block is called for only
a single buffer_head (a 2k buffer_head in this case?) we are only able to tell
the VFS that this 2k is buffer_new().

So when ufs_getfrag_block() is later called to map some more data in the file,
and when that data resides within the remaining 14k of this fragment,
ufs_getfrag_block() will incorrectly return a !buffer_new() buffer_head.

I don't see _right_ way to do nullification of whole block, if use inode
page cache, some pages may be outside of inode limits (inode size), and
will be lost; if use blockdev page cache it is possible to zero real data,
if later inode page cache will be used.

The simpliest way, as can I see usage of block device page cache, but not only
mark dirty, but also sync it during "nullification". I use my simple tests
collection, which I used for check that create,open,write,read,close works on
ufs, and I see that this patch makes ufs code 18% slower then before.

Flag i2c_adapter.dev for removal after userspace tools get upgraded, and
include a near-term code migration aid to facilitate this:

- The class device gets the name attribute it should have had. This
was previously (wrongly) associated with the i2c_adapter.dev node.
Sysfs based tools and libraries can start converting right away.

- Issue a warning for legacy adapter drivers that don't provide any
physical device node; so systems with those drivers will know to
fix this problem earlier.

It's a known fact that Windows times out commands after 7 seconds, so
drives generally try and respond if they can before that happens. We
default to 5 seconds, which sometimes is a bit too short.

Jeremy Higdon reported here:

http://lkml.org/lkml/2007/1/1/145

that his drive takes longer than 5 seconds for a "read track
information" command, later confirming that it is about 6.7 seconds.

So just do the sane thing and change the default command timeout to 7

On the G965, the GTT size may be larger than is required to cover the
aperture. (In fact, on all hardware we've seen, the GTT is 512KB to the
aperture's 256MB). A previous commit forced the aperture size to 512MB on
G965 to match GTT, which would likely result in hangs at best if users
tried to rely on agpgart's aperture size information. Instead, we use the
resource length for the aperture size and the system's reported GTT size
when available for the GTT size.

Because the MSAC registers which had been read for aperture size detection
on i9xx chips just cause a change in the resource size, we can use generic
code for aperture detection on all i9xx.

value. For PowerSaver processors we can't depend on Max /
MinMHzFSB because these values are only used for
PowerSaver 2.0 and 3.0. Most processors on which Longhaul
is used are PowerSaver 1.0 only. I'm changing code for older
CPU's too, but not so much as previously, and this code was
already used for Ezra. Using MinMHzBR for Ezra-T is outside
spec. It is for voltage scaling purpose and don't have to
be equal to minmult (but it is). Same for Nehemiah (it
isn't for sure). Added mult - current multiplier value.

This patch is to speed up flipping of pages in and out of the AGP aperture as
needed by the new drm memory manager.

A number of global cache flushes are removed as well as some PCI posting flushes.
The following guidelines have been used:

1) Memory that is only mapped uncached and that has been subject to a global
cache flush after the mapping was changed to uncached does not need any more
cache flushes. Neither before binding to the aperture nor after unbinding.

2) Only do one PCI posting flush after a sequence of writes modifying page
entries in the GATT.

Both process_zones() and drain_node_pages() check for populated zones
before touching pagesets. However, __drain_pages does not do so,

This may result in a NULL pointer dereference for pagesets in unpopulated
zones if a NUMA setup is combined with cpu hotplug.

Initially the unpopulated zone has the pcp pointers pointing to the boot
pagesets. Since the zone is not populated the boot pageset pointers will
not be changed during page allocator and slab bootstrap.

If a cpu is later brought down (first call to __drain_pages()) then the pcp
pointers for cpus in unpopulated zones are set to NULL since __drain_pages
does not first check for an unpopulated zone.

If the cpu is then brought up again then we call process_zones() which will
ignore the unpopulated zone. So the pageset pointers will still be NULL.

If the cpu is then again brought down then __drain_pages will attempt to
drain pages by following the NULL pageset pointer for unpopulated zones.
