KVM: X86: Introduce mmu_rmaps_stat per-vm debugfs file
Use this file to dump rmap statistic information. The statistic is done by
calculating the rmap count and the result is log-2-based.
An example output of this looks like (idle 6GB guest, right after boot linux):
Rmap_Count: 0 1 2-3 4-7 8-15 16-31 32-63 64-127 128-255 256-511 512-1023
Level=4K: 3086676 53045 12330 1272 502 121 76 2 0 0 0
Level=2M: 5947 231 0 0 0 0 0 0 0 0 0
Level=1G: 32 0 0 0 0 0 0 0 0 0 0
