What users do hit this so hard that it matters?  Seems like the jump
label code uses it directly and throgh __module_text_address, and krobes
use it throug __module_text_address.  Is it the pageattr code or
lockdep?

Also seems interesting that both __module_address and __module_text_address
are exported, but don't seem to have modular users.
