[PATCH] ARM: cleanup vmalloc start/offset macros

Browse Source 
VMALLOC_START and VMALLOC_OFFSET are common between all ARM
machine classes.  Move them into include/asm-arm/pgtable.h,
but allow a machine class to override them if required.

/*
* Just any arbitrary offset to the start of the vmalloc VM area: the
* current 8MB value just means that there will be a 8MB "hole" after the
* physical memory until the kernel virtual memory starts. That means that
* any out-of-bounds memory accesses will hopefully be caught.
* The vmalloc() routines leaves a hole of 4kB between each vmalloced
* area for the same reason. ;)
