["Jason R Thorpe" <thorpej%netbsd.org@localhost>]

Module Name:    src
Committed By:   thorpej
Date:           Wed Oct 27 04:45:42 UTC 2021

Modified Files:
        src/sys/arch/aarch64/include: signal.h
        src/sys/arch/amd64/include: signal.h
        src/sys/kern: kern_sig.c sys_sig.c

Log Message:
- In sendsig() and sigaction1(), don't hard-code signal trampoline
  versions.  Instead, use the version constants from <sys/signal.h>
  and automatically (and correctly) handle cases where multiple versions
  of a particular trampoline flavor exist.  Conditionalize support
  for sigcontext trampolines on __HAVE_STRUCT_SIGCONTEXT.
- aarch64 and amd64 don't use sigcontext natively, but do need to
  support it for 32-bit compatibility; define __HAVE_STRUCT_SIGCONTEXT
  conditionally on _KERNEL.
