With this, the guest can use 1TB segments as well as 256MB segments. Since we now have the situation where a single emulated guest segment could correspond to multiple shadow segments (as the shadow segments are still 256MB segments), this adds a new kvmppc_mmu_flush_segment() to scan for all shadow segments that need to be removed. This restructures the guest HPT (hashed page table) lookup code to use the correct hashing and matching functions for HPTEs within a 1TB segment. We use the standard hpt_hash() function instead of open-coding the hash calculation, and we use HPTE_V_COMPARE() with an AVPN value that has the B (segment size) field included. The calculation of avpn is done a little earlier since it doesn't change in the loop starting at the do_second label. The computation in kvmppc_mmu_book3s_64_esid_to_vsid() changes so that it returns a 256MB VSID even if the guest SLB entry is a 1TB entry. This is because the users of this function are creating 256MB SLB entries. We set a new VSID_1T flag so that entries created from 1T segments don't collide with entries from 256MB segments.
