But why?

I bet you someone will get confused and mean
CONFIG_MITIGATION_PAGE_TABLE_ISOLATION when she means
CONFIG_MITIGATION_ADDRESS_SPACE_ISOLATION or vice versa due to the
conglomerate of similar words.

Now compare that to CONFIG_ASI! Wonderfully short and clear.

Especially when the namespace already is "asi_" ...

The only problem with ASI is it doesn't tell you what it is but you can look
it up with simple grepping...

I'd say.
