parisc: rename parisc's vmalloc_start to parisc_vmalloc_start
building kernel 2.6.32(pre), gives this compiler warning:
/linus-linux-2.6/mm/vmalloc.c: In function 'pcpu_get_vm_areas':
/linus-linux-2.6/mm/vmalloc.c:2104: warning: 'vmalloc_start' is used
uninitialized in this function
The reason is, that the code in mm/vmalloc defines a local variable called
vmalloc_start, which is already defined as global variable in parisc's code.
To avoid this kind of problems in future, I suggest to rename the parisc
variable
to parisc_vmalloc_start.
