causes receive hangs and doesn't help performance much anyway.

This patch fixes a problem plaguing Dell notebooks with built-in b44
ethernet: The driver refuses to transmit packets of any kind until after
the first 5-second tx_timeout occurs. This bug causes DHCP negotiation to

Use an increasing local ID to avoid re-using identifiers while

Unlike tavor, the max work queue size is an exact power of 2 for arbel
mode, despite what the documentation (of the QUERY_DEV_LIM firmware
command) says. Without this patch, on Arbel, we can start with a QP
of a valid size and get above the reported limit after rounding to the
next power of two.

This is what a lot of drivers will actually want to use to insert
individual pages into a user VMA. It doesn't have the old PageReserved
restrictions of remap_pfn_range(), and it doesn't complain about partial
remappings.
The page you insert needs to be a nice clean kernel allocation, so you
can't insert arbitrary page mappings with this, but that's not what
people want.
