[11/75] SCSI: mpt2sas: _scsih_smart_predicted_fault uses GFP_KERNEL in interrupt context

[Greg KH]

3.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Anton Blanchard <anton@xxxxxxxxx>

commit f6a290b419a2675c4b77a6b0731cd2a64332365e upstream.

_scsih_smart_predicted_fault is called in an interrupt and therefore
must allocate memory using GFP_ATOMIC.
