["Ryota Ozaki" <ozaki-r%netbsd.org@localhost>]

Module Name:    src
Committed By:   ozaki-r
Date:           Thu Jun 16 02:34:33 UTC 2016

Modified Files:
        src/sys/sys: lwp.h

Log Message:
Introduce curlwp_bind and curlwp_bindx

The API prevents the current LWP from migrating between CPUs during
the critical section (between curlwp_bind and curlwp_bindx). One use
case of it is psref(9) that has a contract that forbids such migrations.

Proposed at http://mail-index.netbsd.org/tech-kern/2016/06/13/msg020710.html
(check it out if you want to know why the function names are chosen)
