David,
I removed the select/poll patch (was 5/7 in v9) from the set. The rest are the same patches that were in v9.
Please consider applying.
Thanks to everyone for their input.

Change log: v10 - removed select/poll support. (we will work on this some more and try again) v9 - correct sysctl proc_handler, reported by Eric Dumazet and Amir Vadai. - more int -> bool changes, reported by Eric Dumazet. - better mask testing in sock_poll(), reported by Eric Dumazet.
v8 - split out udp and select/poll into separate patches. what used to be patch 2/5 is now three patches. - type corrections from Amir Vadai and Cong Wang: one unsigned long that was left when changing to cycles_t int -> bool - more detailed patch descriptions.
v7 - suggested by Ben Hutchings and Eric Dumazet: type fixes, static for globals in net/core.c, avoid napi_id collisions in napi_hash_add()
v6 - many small fixes suggested by Eric Dumazet: data locality, typos, documentation protect napi_hash insert/delete with a spinlock (napi_gen_id is no longer atomic_t since it's only accessed with the spinlock held.) - added IPv6 TCP and UDP support (only minimally tested)
v5 - corrections suggested by Ben Hutchings: fixed typos, moved the config option and sysctl value from IPv4 to net - moved sk_mark_ll() to the protocol handlers - removed global id mechanism, replaced with a hashed napi_id. based on code sample from Eric Dumazet Note that ixgbe_free_q_vector() already waits an rcu grace period before freeing the q_vector, so nothing additional needs to be done when adding a call to napi_hash_del(). - simple poll/select support
v4 - removed separate config option for TCP as suggested Eric Dumazet. - added linux mib counter for packets received through the low latency path, as suggested by Andi Kleen. - re-allow module unloading, remove module param, use a global generation id instead to prevent the use of a stale napi pointer, as suggested by Eric Dumazet - updated Documentation/networking/ip-sysctl.txt text
v3 - coding style changes suggested by Dave Miller
v2 - the sysctl knob is now in microseconds. The default value is now 0 (off). - for now the code depends at configure time on CONFIG_I86_TSC - the napi reference in struct skb is now a union with the dma cookie since the former is only used on RX and the latter on TX, as suggested by Eric Dumazet. - we do a better job at honoring non-blocking operations. - removed busy-polling support for tcp_read_sock() - remove dynamic disabling of GRO - coding style fixes - disallow unloading the device module after the feature has been used
