ATAPI devices transfer fixed number of bytes for CDBs (12 or 16). Some
ATAPI devices choke when shorter CDB is used and the left bytes contain
garbage. Block SG_IO cleared left bytes but SCSI SG_IO didn't. This patch
makes SCSI SG_IO clear it and simplify CDB clearing in block SG_IO.

When CIFS is the lower filesystem, the old lower dentry needs to be explicitly
dropped from inside eCryptfs to force a revalidate. In addition, when CIFS is
the lower filesystem, the inode attributes need to be copied back up from the
lower inode to the eCryptfs inode on an eCryptfs revalidate.

if (unlikely(!area))
return NULL;

It is leaking `area', also original code seems strange already.

Based on patch by James D. Nurmi:
I've got some code very dependant on nfnetlink_queue, and turned up a
large number of warns coming from skb_trim. While it's quite possibly
my code, having not seen it on older kernels made me a bit suspect.
Anyhow, based on some googling I turned up this thread:
http://lkml.org/lkml/2006/8/13/56
And believe the issue to be related, so attached is a small patch to

else hitting the WARN_ON(1) in skbuff.h, it might be helpful..

The windfarm code, in it's current incarnation, uses request_module() to
load the various submodules it needs for a given platform so that only
the main platform control module needs to be modprobed. However, it was
missing various bits. This fixes it. In the future, we'll use some
hotplug mecanisms to try to get all of this auto-loaded on the platforms
where it matters but that isn't ready yet.

When called to do a transfer that has a start offset within the cache
line which is uneven between source and destination and a length which
terminates the source of the copy exactly on a cache line, one extra
line gets copied into a temporary buffer. This is normally not an issue
since the buffer is a kernel buffer and only the requested information
gets copied into the user buffer.
The problem arises when the source ends at the very last physical page
of memory. That last cache line does not exist and results in the SHUB
chip raising an MCA.

Komuro reports that ISA interrupts do not work after a disable_irq(),
causing some PCMCIA drivers to not work, with messages like
eth0: Asix AX88190: io 0x300, irq 3, hw_addr xx:xx:xx:xx:xx:xx
eth0: found link beat
eth0: autonegotiation complete: 100baseT-FD selected
eth0: interrupt(s) dropped!
eth0: interrupt(s) dropped!
eth0: interrupt(s) dropped!
...
Linus Torvalds <torvalds@osdl.org> said:
"Now, edge-triggered interrupts are a _lot_ harder to mask, because the
Intel APIC is an unbelievable piece of sh*t, and has the edge-detect logic
_before_ the mask logic, so if a edge happens _while_ the device is
masked, you'll never ever see the edge ever again (unmasking will not
cause a new edge, so you simply lost the interrupt).
So when you "mask" an edge-triggered IRQ, you can't really mask it at all,
because if you did that, you'd lose it forever if the IRQ comes in while
you masked it. Instead, we're supposed to leave it active, and set a flag,
and IF the IRQ comes in, we just remember it, and mask it at that point
instead, and then on unmasking, we have to replay it by sending a
self-IPI."
This trivial patch solves the problem.

This reverts commit 0130b0b32e.
Sergey Vlasov points out (and Vadim Lobanov concurs) that the bug it was
supposed to fix must be some unrelated memory corruption, and the "fix"
actually causes more problems:
"However, the new code does not look safe in all cases. If some other
task has opened more files while dup_fd() released oldf->file_lock, the
new code will update open_files to the new larger value. But newf was
allocated with the old smaller value of open_files, therefore subsequent
accesses to newf may try to write into unallocated memory."
so revert it.

When building a monolithic kernel, the load order of drivers does not
work for SAS libata users, resulting in a kernel oops.
Convert libata to use subsys_initcall instead of module_init, which
ensures that libata gets loaded before any LLDD.
This is the same thing that scsi core does to solve the problem. The
load order problem was observed on ipr SAS adapters and should exist for
other SAS users as well.
