Yes, I was already aware of that issue (big-endian only), and have a
patch queued for 5.0.3:
- Fix for "swap" and "kmem -i" commands on 2.6.29 or later, big-endian,
ppc64 kernels, where the swap_info_struct.flags member was changed
from an int to a long. Without the patch, the "swap" command does
not display any swap data, and the "kmem -i" command indicates that
there is no swap memory used or available.
