Kyoji Ogasawara says:

====================
smc-sysctl formatting and missing entries

update SMC sysctl documentation in two small steps.

- patch 1 fixes indentation in the smcr_buf_type section
- patch 2 documents missing sysctl parameters limit_smc_hs and hs_ctrl,
  including values/defaults and hs_ctrl usage notes
