This patch replaces the code for getting an unsigned long from a
userspace buffer by a simple call to kstroul_from_user.
This makes it easier to read and less error prone.

To use raw track access some special storage server commands are

The size of the buffer that is used to store DASD statistics input
strings depends on the user input. If the input string is to large,
the write operation could fail with -ENOMEM. To avoid this, use
vmalloc instead of kmalloc.

The SIGA-W may return with the busy bit set which means the device was
blocked. The busy loop which retries the SIGA-W for 100us may not be
long enough when running under a heavily loaded hypervisor.
Extend the retry mechanism by adding a longer second stage which retries
the SIGA-W for up to 10s. In difference to the first retry loop the second
stage is using mdelay to stop the cpu between the retries and thereby
avoid additional preassure in on the hypervisor.
If the second stage retry is successfull a device reset is avoided.

1) In be_probe(), as soon as the MCC Q is created a gratuitous link status
event is received and processed. Accordingly netif_carrier_off/on() is called.
The extra netif_carrier_off() call in probe can race with this and cause wrong
state.
2) be_close() need not call netif_carrier_off(). It is OK to show the actual
link state even when the device is administratively down.

Problem: HW DDP context was not invalidated in case of ABORTS, etc...
This leads to the problem where memory pages which are used for DDP
as user descriptor could get reused for some other purpose (such as to
satisfy new memory allocation request either by kernel or user mode threads)
and since HW DDP context was not invalidated, HW continue to write to
those pages, hence causing memory corruption.
Fix: Either on incoming ABORTS or due to exchange time out, allowed the
target to cleanup HW DDP context if it was setup for respective ft_cmd.
Added new function to perform this cleanup, furthur it can be enhanced
for other cleanup activity. Fix ft_recv_write_data() to properly handle
fc_frame_payload_get to return pointer to payload if it exist. If there is
no payload which is most common case (+ve case in case if DDP is working
as expected, it will return NULL. Yes, scope of buf is limited to printk.
Invalidation of HW context (which is done inside ft_invl_hw_context() is
necessary in SUCCESS and FAILURE case of DDP. Hence invalidation is DONE
as long as there was DDP setup (whether it worked correctly or not,
NOTE: For some reason, if there is any error w.r.t DDP such as out of
order packet reception, HW simply post the full packet in rx queue.

When loading aes via the module alias, a padlock module failing to
load due to missing hardware is not particularly notable. With
v2.6.27-rc1~1107^2~14 (crypto: padlock - Make module loading quieter
when hardware isn't available, 2008-07-03), the padlock-aes module
suppresses the relevant messages when the "quiet" flag is in use; but
better to suppress this particular message completely, since the
administrator can already distinguish such errors by the absence of a
message indicating initialization failing or succeeding.
This avoids occasional messages in syslog of the form
padlock_aes: VIA PadLock not detected.

In this code, blkvsc_req is allocated in the cache blkdev->request_pool,
but freed in the first case to the cache blkvsc_req->dev->request_pool.
blkvsc_req->dev is subsequently initialized to blkdev, making these the
same at the second call to kmem_cache_free. But at the point of the first
call, blkvsc_req->dev is NULL. The second call is changed too, for
uniformity.
