[parisc-linux] explicitly allocate executable pages?

[Grant Grundler]

Could someone explain the following code in arch/parisc/mm/init.c?

The #warning doesn't make sense to me since it's inside !defined()
for the thing it's talking about.

thanks,
grant

#if !defined(CONFIG_STI_CONSOLE)
#warning STI console should explicitly allocate executable pages but does not
