src/sys/arch/aarch64/aarch64: vm_machdep.c
Log Message:
Fix clone(2) for COMPAT_NETBSD32.
(1) Set r13 (sp for arm32 processes) appropriately when stack is
specified to fork1().
(2) For arm32 processes, align stack to 8-byte boundary, instead of
16-byte for native aarch64 processes, to match our 32-bit ABI:
https://nxr.netbsd.org/xref/src/sys/arch/arm/arm32/vm_machdep.c#150
Note that sp alignment checking is disabled in aarch32 mode, and
this works fine with AARCH64_EL0_STACK_ALIGNMENT_CHECK option.
OK ryo
