Subject: [PATCH 4/5] pagemap: Make /proc/kpage{count,flags} return EINVAL (not EIO) on unaligned read.

If a process tries to read at a position that's not a multiple of 8,
or for a count that's not a multiple of 8, they've passed an invalid
argument to read (for this file), so we should return EINVAL.
