CVS commit: [netbsd-9] src/sys

["Martin Husemann" <martin%netbsd.org@localhost>]

Module Name:    src
Committed By:   martin
Date:           Tue Mar 10 06:47:55 UTC 2020

Modified Files:
        src/sys/arch/amd64/amd64 [netbsd-9]: trap.c
        src/sys/compat/netbsd32 [netbsd-9]: netbsd32_mod.c

Log Message:
Pull up following revision(s) (requested by pgoyette in ticket #778):

        sys/compat/netbsd32/netbsd32_mod.c: revision 1.20
        sys/arch/amd64/amd64/trap.c: revision 1.127

Rework previous, so that the real syscall code is not invoked from within
the module_hook code.  Otherwise, if the syscall just happens to be exit()
we will exit while still holding a reference to the hook's localcount, and
nothing will ever release that reference.  Attempts to manually unload the
module will hang indefinitely, as will modstat(8).
