Julia Lawall cc9a2c8301 arch/alpha/kernel: Add kmalloc NULL tests 
Check that the result of kmalloc is not NULL before passing it to other
functions.

The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
expression *x;
identifier f;
constant char *C;
@@

x = \(kmalloc\|kcalloc\|kzalloc\)(...);
... when != x == NULL
    when != x != NULL
    when != (x || ...)
(
kfree(x)
f(...,C,...,x,...)
|
*f(...,x,...)
|
*x->f
)
// </smpl>
