  'PBRSB-eIBRS: SW sequence'   CPU is affected and protection of RSB on VMEXIT enabled

  'PBRSB-eIBRS: Vulnerable'    CPU is vulnerable

  'PBRSB-eIBRS: Not affected'  CPU is not affected by PBRSB

Full mitigation might require a microcode update from the CPU

vendor. When the necessary microcode is not available, the kernel will

report vulnerability.

sctp_wmem  - vector of 3 INTEGERs: min, default, max

	Currently this tunable has no effect.

	Only the first value ("min") is used, "default" and "max" are

	ignored.



	min: Minimum size of send buffer that can be used by SCTP sockets.

	It is guaranteed to each SCTP socket (but not association) even
