Force a netdevice poll in net_tx() before attempting to transmit
...
packet, to work around the problem whereby small TX rings get backed
up because we haven't yet poll()ed for TX completions.

Redefine bzimage_exec_context::mem_limit to be the highest permissible
...
byte, rather than the number of permissible bytes (i.e. subtract one
from the value under the previous definition to get the value under
the new definition).
This avoids integer overflow on 64-bit kernels, where
bzhdr.initrd_addr_max may be 0xffffffffffffffff; under the old
behaviour we set mem_limit equal to initrd_addr_max+1, which meant it
ended up as zero. Kernel loads would fail with ENOBUFS.

Added an almost obscene amount of debugging and assertion code while

tracking down a bug that turned out to be a free_iob() used where I
