Subject: Re: [PATCH] x86: io-apic - get rid of __DO_ACTION macro

Yinghai, the base idea with mask is to apply a mask only if you need
it. And having _and_ operation to be mandatory implemented is a
limitation and just not enough. So that is why i do check if mask is
defined (well it cold be not a good practice indeed). Thanks for
notice (and about binary operator too - will fix :)
