["Mindaugas Rasiukevicius" <rmind%netbsd.org@localhost>]

Module Name:    src
Committed By:   rmind
Date:           Tue Nov 26 20:29:40 UTC 2013

Modified Files:
        src/sys/arch/x86/x86: nmi.c
        src/sys/kern: subr_pcu.c subr_xcall.c

Log Message:
Switch XC_HIGHPRI to run at IPL_SOFTSERIAL i.e. the highest software level.
Adjust pcu(9) to this xcall(9) change.  This may fix the problems after
x86 FPU was converted to use PCU, since it avoids heavy contention at the
lower levels (particularly, IPL_SOFTNET).  This is a good illustration why
software interrupts should generally avoid any blocking on locks.
