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.

If all of the entropy is in the local and foreign addresses,
but xor'ing together would cancel out that entropy, the
current hash performs poorly.
Suggested by Cosmin Ratiu:
Basically, the situation is as follows: There is a client
machine and a server machine. Both create 15000 virtual
interfaces, open up a socket for each pair of interfaces and
do SIP traffic. By profiling I noticed that there is a lot of
time spent walking the established hash chains with this
particular setup.
The addresses were distributed like this: client interfaces
were 198.18.0.1/16 with increments of 1 and server interfaces
were 198.18.128.1/16 with increments of 1. As I said, there
were 15000 interfaces. Source and destination ports were 5060
for each connection. So in this case, ports don't matter for
hashing purposes, and the bits from the address pairs used
cancel each other, meaning there are no differences in the
whole lot of pairs, so they all end up in the same hash chain.

Fix the problem that the following error message is sometimes displayed
at irq migration when vector domain is enabled.
"Unexpected interrupt vector %d on CPU %d is not mapped to any IRQ!"
The cause of this problem is an interrupt is sent to the previous
target CPU after cleaning up vector to irq mapping table. To clean up
vector to irq map on the previous target CPU safty, change the irq
migration in multiple vector domain as follows. The original idea is
from x86 interrupt management code.
- Delay vector to irq table cleanup until the interrupts are sent
to new target CPUs. By this, it is ensured that target CPU is
completely changed on the interrupt controller side.
- Even after the interrupts are sent to new target CPUs, there can
be pended interrupts remaining on the previous target CPU. So we
need to delay clearning up vector to irq table until the pended
interrupt is handled. For this, send IPI to the previous target
CPU with lower priority vector and clean up vector to irq table
in its handler.
This patch affects only to irq migration code with multiple vector
domain is enabled.
