When I called p54_parse_eeprom() on a hand-coded structure
I managed to make a small mistake with wrap->len which caused
a segfault a few lines down when trying to read entry->len.
This patch changes the validation code to avoid such problems.

Due to the class_device cleanup of pci_bus, the error messages when

Fix following warning:
WARNING: vmlinux.o(.text+0x47bdb1): Section mismatch in reference from the function pci_scan_child_bus() to the function .devinit.text:pcibios_fixup_bus()
We had plenty of functions that could be annotated __devinit but due to
the former restriction that exported symbols could not be annotated
they were not so. So annotate these function and fix the references
from the pci/hotplug/* code to silence the resuting warnings.

This patch (as1037) makes a small update to the earlier as1035 patch.
The minimum-length computation shouldn't be done in
usb_stor_access_xfer_buf(), since that routine can be called multiple
times for a single transfer. It should be done in
usb_stor_set_xfer_buf() instead, which gets called only once.
The way it is now isn't really _wrong_, but it isn't really _right_
either. Moving the statement will be an improvement.

USB: ehci: Fixes completion for multi-qtd URB the short read case
When use of urb->status in the EHCI driver was reworked last August
(commit 14c04c0f88f228fee1f412be91d6edcb935c78aa), a bug was inserted
in the handling of early completion for bulk transactions that need
more than one qTD (e.g. more than 20KB in one URB).
This patch resolves that problem by ensuring that the early completion
status is preserved until the URB is handed back to its submitter,
instead of resetting it after each qTD.

The MPC83xx(MPC8349, MPC8360) are also supported.

This patch removes the #define READ_AHEAD 1024 from the driver and uses the
block layer defaults, instead. We have found that under certain workloads
the setting can cause a disk connected to the e200 controller to go offline.
If the disk hiccups the link may try to downshift but the controller is
never notified that the link successfully completed the renegotiation.
We've also found that performance using the block layer default of 32 pages
was on par with the 1024 setting. We tried setting it to zero at one time
based on info from our firmware guys but that killed performance. Turns out
we were talking about 2 different read ahead settings.
Please consider this for inclusion.

Block layer alignment was used for two different purposes - memory
alignment and padding. This causes problems in lower layers because
drivers which only require memory alignment ends up with adjusted
rq->data_len. Separate out padding such that padding occurs iff
driver explicitly requests it.

The meaning of rq->data_len was changed to the length of an allocated
buffer from the true data length. It breaks SG_IO friends and
bsg. This patch restores the meaning of rq->data_len to the true data
length and adds rq->extra_len to store an extended length (due to
drain buffer and padding).
This patch also removes the code to update bio in blk_rq_map_user
introduced by the commit 40b01b9bbdf51ae543a04744283bf2d56c4a6afa.
The commit adjusts bio according to memory alignment
(queue_dma_alignment). However, memory alignment is NOT padding
alignment. This adjustment also breaks SG_IO friends and bsg. Padding
alignment needs to be fixed in a proper way (by a separate patch).
