 Module Name:	src
 Committed By:	rin

 Modified Files:
 	src/sys/arch/amd64/include: param.h
 
 Log Message:
 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.
