NetBSD/src cQEXg6P — sys/kern kern_lwp.c
Preserve pcu(9) state in fork. There should perhaps be a pcu_fork operation to keep this factored neatly but this will be simpler to pull up. In practical terms, this may not affect most architecture that use pcu(9) -- alpha, arm32, mips, powerpc, riscv -- but it does affect aarch64, in which v8-v15 are callee-saves, and GCC actually takes advantage of them, and for more than just floating-point data too.
