Modified Files: src/share/man/man9: xcall.9 src/sys/kern: subr_xcall.c src/sys/sys: xcall.h Log Message: Support arbitrary softint IPLs in high priority xcall The high priority xcall supported only a softint of IPL_SOFTSERIAL. It meant that it didn't work for xcall callbacks depending on lower IPLs than IPL_SOFTSERIAL. The change makes xcall have multiple softints of IPLs and allow users to specify arbitrary IPLs. Users can specify an IPL by XC_HIGHPRI_IPL passed to the 1st argument of xc_broadcast or xc_unicast. Note that xcall still serves requests one by one (i.e., doesn't run them concurrently) even if requests have different IPLs.
