This is the kernel module for flushing & subsequently invalidating all caches/NPT/TLB on all CPU(s) via write-back.
For NPT: Only Intel EPT is currently supported (if not supported, there will be no interface created).
For flushing cache: Write "1" to /sys/kernel/cache/flush via echo 1 | sudo tee /sys/kernel/cache/flush.
For flushing NPT: Write "1" to /sys/kernel/npt/flush via echo 1 | sudo tee /sys/kernel/npt/flush.
For flushing TLB: Write "1" to /sys/kernel/tlb/flush via echo 1 | sudo tee /sys/kernel/tlb/flush.
