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. Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
