Subject: mm/vmalloc.c: don't use vmalloc_end
From: "Jan Beulich" <JBeulich@xxxxxxxxxx>
At least on ia64 vmalloc_end is a global variable that VMALLOC_END expands
to. Hence having a local variable named vmalloc_end and initialized from
VMALLOC_END won't work on such platforms. Rename these variables, and for
consistency also rename vmalloc_start.
