8964ebb8c3 ACPI: remove redundant Acer blacklist entry
dmi_check_system() does sub-string matching using strstr(),
rather than exact string compares with !strcmp().

So delete the longer of the Acer blacklist entries, as its
function is just a redundant console message.

124d3b7041 fix writev regression: pan hanging unkillable and un-straceable
Frederik Himpe reported an unkillable and un-straceable pan process.

Zero length iovecs can go into an infinite loop in writev, because the
iovec iterator does not always advance over them.

The sequence required to trigger this is not trivial. I think it
requires that a zero-length iovec be followed by a non-zero-length iovec
which causes a pagefault in the atomic usercopy. This causes the writev
code to drop back into single-segment copy mode, which then tries to
copy the 0 bytes of the zero-length iovec; a zero length copy looks like
a failure though, so it loops.

Put a test into iov_iter_advance to catch zero-length iovecs. We could
just put the test in the fallback path, but I feel it is more robust to
skip over zero-length iovecs throughout the code (iovec iterator may be
used in filesystems too, so it should be robust).
