[12/21] ARM: Fix MULTI_TLB for feroceon

Commit Message

Andrew Lunn Feb. 6, 2014, 11:42 p.m. UTC

Feroceon has the same flush operations as v4wbi, but has an additional
flag, TLB_L2CLEAN_FR. When building with MULTI_TLB this flag is placed
into cpu_tlb.tlb_flags, so there needs to be a cpu_tlb specifically
for feroceon, rather than sharing the v4wbi.
