Refactoring broke the balloon driver, and fixing kallsyms on ARM broke

some (non-ARM) MMUless setups, so we're making that fix ARM-only for now.
 
 Unfortunately, the ARM refactoring which broke kallsyms/perf was CC:stable,
 so the fix (which broken non-ARM) was also CC:stable, so now the partial
 reversion is also CC:stable...
 
 Cheers,
 Rusty.
