It's a hex value - 0x8000 - but you are correct it should be 0x2000. 
It's not fatal, just makes things a little slower when the code in 
pgalloc.h loops through and clears the cache.

It's relevant in existing targets - mbvanilla_net and suzaku.  It will 
soon be irrelevant, when the autoconfiguration stuff is finalised.
