[Américo Wang]

This patch fixes this error:

arch/um/kernel/mem.c: In function ‘init_highmem’:        
arch/um/kernel/mem.c:177: error: ‘pkmap_page_table’ undeclared (first
use in this function)                                 
arch/um/kernel/mem.c:177: error: (Each undeclared identifier is
reported only once      
arch/um/kernel/mem.c:177: error: for each function it appears in.)  

Compile and run tested.
