H A Dstage2_mmu.hhdiff 10820:e2a283400c43 Tue May 05 03:22:00 EDT 2015 Andreas Hansson <andreas.hansson@arm.com> arch, cpu: Do not forward snoops to table walker

This patch simplifies the overall CPU by changing the TLB caches such
that they do not forward snoops to the table walker port(s). Note that
only ARM and X86 are affected.

There is no reason for the ports to snoop as they do not actually take
any action, and from a performance point of view we are better of not
snooping more than we have to.

Should it at a later point be required to snoop for a particular TLB
design it is easy enough to add it back.
