We disable BSP if boot cpu is AP.
INIT-INIT-SIPI sequence, a protocal to initiate AP, cannot be used for
BSP since it causes BSP jump to BIOS init code; typical visible
behaviour is hang or immediate reset, depending on the BIOS init code.
INIT can be used to reset AP in a fatal system error stat
Part of boot-up code assumes booting CPU is BSP, but kexec can enter

dw_dmac driver already supports device tree but it used to have its platform
data passed the non-DT way.
This patch does following changes:
- pass platform data via DT, non-DT way still takes precedence if both are used.
- create generic filter routine
- Earlier slave information was made availabl
This patch adds dw_dmac's platform data to DT node. It also creates slave info
node for SPEAr13xx, for the devices which were using dw_dmac.

[oops, fixing LKML address]
If you plug in a USB storage device and then suspend, resume, and
quickly suspend again, the system may freeze. 2 minutes later you'll
get the following message.

Hi Andrew,
Today's linux-next merge of the akpm tree got a conflict in
arch/arm64/kernel/sys_compat.c between commit 0fe8f08036a2 ("arm64: Use
generic sys_execve() implementation") from the signal tree and commit
"compat: generic compat_sys_sched_rr_get_interval implementation" from
the akpm tree.

That's probably fallout from the whole UAPI thing.

Commit a07f7672d7cf0ff0d6e548a9feb6e0bd016d9c6c added user-space copies
of the byteshift headers to be used by hostprogs, changing e.g. u8 to __u8.
However, in order to cross-compile the kernel from a non-Linux system,
stdint.h types need to be used instead of linux/types.h

The userland aoetools package includes an "aoe-stat" command that
can display a "payload size" column when the aoe driver exports
this information. Users can quickly see what amount of user data
is transferred inside each AoE command on the network, network
headers excluded.

The GPFS filesystem is an example of an aoe user that requires the
aoe driver to support I/O request sizes larger than the default.
Most users will not need large I/O request sizes, because they would
need to be split up into multiple AoE commands anyway.

Users sometimes want to cause the aoe driver to forget a
particular previously discovered device when it is no longer
online. The aoetools provide an "aoe-flush" command that users
run to perform this administrative task. The changes below
provide the support needed in the driver.
Signed-off-by:
The ATA over Ethernet config query response contains a "buffer count"
field reflecting the AoE target's capacity to buffer incoming AoE
commands.
By taking the current value of this field into accound, we increase
performance throughput or avoid network congestion, when the value
has increased or
Dropped transmits are not common, but when they do occur, increasing
the transmit queue length often helps.

This patch series is based on linux-next/akpm from 11 Oct.
The patch that modifies aoenet.c:tx to print a warning does not affect
locking but nonetheless causes a new sparse context warning to appear.
Before a bug in sparse suppressed the warning. We will soon be able
to use the new __must_hold()
convert_name_to_addr() allocated sizeof(char *) * MAX_PROBE_ARGS
