History
Stephan Uphoff 4c0e268adf Ensure that a thread stays on same CPU when calculating per CPU 
TLB shootdown requirements. Otherwise a CPU may not get the needed
TLB invalidation.

The PTE valid and access flags can not be used here to avoid TLB
shootdowns unless sf->cpumask == all_cpus.
( Otherwise some CPUs may still hold an even older entry in the TLB)
Since sf_buf_alloc mappings are normally always used this is
also not really useful and presetting accessed and modified
allows the CPU to speculatively load the entry into the TLB.

Both bugs can cause random data corruption.
