Per process DSCR + somefixes (try#3)

step1: http://patchwork.ozlabs.org/patch/71489/
step2: http://patchwork.ozlabs.org/patch/81423/

In step2 I defined sysfs node as:

static SYSDEV_ATTR(dscr_default, 0600, show_dscr_default, store_dscr_default);

and it caused problems with rhel6.
Now it is:

static SYSDEV_CLASS_ATTR(dscr_default, 0600, show_dscr_default, store_dscr_default);

It works now on both 2.6.32 and 2.6.36 but is that correct?
