Module Name:    src

Modified Files:
        src/sys/arch/aarch64/aarch64: netbsd32_machdep.c

Log Message:
For rev 1.14 and before, netbsd32_process_write_regs() returns EINVAL
if non-modifiable bits are set in CPSR.

Instead, mask out non-modifiable bits and make this function success
regardless of value in CPSR. New behavior matches that of arm:

https://nxr.netbsd.org/xref/src/sys/arch/arm/arm/process_machdep.c#187

This fixes lib/libc/sys/t_ptrace_wait*:access_regs6 tests, in which
register contents retrieved by PT_GETREGS are set back by PT_SETREGS.

No new regression is observed in full ATF run.

OK ryo
