Subject: sparc64 mystery with Cheetah+ D-cache parity error
(n_tty_set_termios, bpf_check, cheetah_copy_page_insn)
I have seen multiple strange messages like this, on multiple sparc64 machines:
[ 55.523882] CPU[1]: Cheetah+ D-cache parity error at TPC[0000000000707e8c]
[ 55.626033] TPC<n_tty_set_termios+0x2c/0x3c0>
This specfic one ise from n_tty_set_termios and it is currently repeatable on a Sun V210.
I have seen these on V245 and V445 too, with different addresses. On V445, the same address caused
errors on multiple CPUs so it does not seem like a hardware problem, rather something software releated,
that's why I am reporting it here.
On V445 it is gone with my current custom kernels but was there with 4.16.0-1-sparc64-smp Debian kernel package,
probabaly because I do not have bpfilter compiled in:

The last one is from 4.19.0-rc7-00009-g0854ba5 and it has happened only on one boot of this kernel, out of 4,
so it is somewhat nondeterministic. This is the same kernel that made me think it does not happen with current
kernels - well, it did with the same image once.
On V210, it has happened since 4.19.0-rc4-00022-gad3273d and is still happening with 4.19.0-rc7-00009-g0854ba5.
