This reverts commit 59287c0913.
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).

Apparently no ATAPI CD/DVD actually supports REPORT LUNS (in spite of
claiming scsi-3 compliance, where it's mandatory) and worse, some
crash or flake out on being sent the command. This may actually be
due to a conflict between SPC and MMC with MMC not listing REPORT LUNS
as mandatory. The same standards conflict exists for RBC as well.
Fix all of this by reversing the blacklists for CDROM and RBC devices
(i.e. now they have to have the BLIST_REPORTLUNS2 flag set even if the
inquiry data returns scsi-3 compliance).

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.

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.

The HPT37x driver very carefully handles DMA completions and the needed
fixups are done on pci registers 0x50 and 0x52. This is unfortunate
because the actual registers are 0x50 and 0x54. Fixing this offset cures
the second channel problems reported.
Secondly there are some problems with the HPT370 and certain ATA drives.
The filter code however only filters ATAPI devices due to a reversed type
check.
