 Module Name:	src
 Committed By:	martin
 Date:		Fri Mar 29 19:39:06 UTC 2019
 Modified Files:
 	src/sys/arch/amd64/include [netbsd-8]: param.h
 Log Message:
 Pull up following revision(s) (requested by rin in ticket #1220):
 	sys/arch/amd64/include/param.h: revision 1.30
 Bump STACK_ALIGNBYTES to (16 - 1) to satisfy requirement by AMD64
 System V ABI in kernel level. This is because
 (1) for LLDB, we want to bypass libc/csu (and therefore manual stack
      alignment in _start), and
 (2) rtld in glibc >= 2.23 for Linux/x86_64 requires it.
 Fix SEGV for Linux/x86_64 binaries with glibc >= 2.23, reported as
 PR port-amd64/54052.
