Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6.26
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6.26: (1090 commits) [NET]: Fix and allocate less memory for ->priv'less netdevices [IPV6]: Fix dangling references on error in fib6_add(). [NETLABEL]: Fix NULL deref in netlbl_unlabel_staticlist_gen() if ifindex not found [PKT_SCHED]: Fix datalen check in tcf_simp_init(). [INET]: Uninline the __inet_inherit_port call. [INET]: Drop the inet_inherit_port() call. SCTP: Initialize partial_bytes_acked to 0, when all of the data is acked. [netdrvr] forcedeth: internal simplifications; changelog removal phylib: factor out get_phy_id from within get_phy_device PHY: add BCM5464 support to broadcom PHY driver cxgb3: Fix __must_check warning with dev_dbg. tc35815: Statistics cleanup natsemi: fix MMIO for PPC 44x platforms [TIPC]: Cleanup of TIPC reference table code [TIPC]: Optimized initialization of TIPC reference table [TIPC]: Remove inlining of reference table locking routines e1000: convert uint16_t style integers to u16 ixgb: convert uint16_t style integers to u16 sb1000.c: make const arrays static sb1000.c: stop inlining largish static functions ...

- * Using a dynamic percpu 'int' variable has a cost :
- * 1) Extra dereference
- * Current per_cpu_ptr() implementation uses an array per 'percpu variable'.
- * 2) memory cost of NR_CPUS*(32+sizeof(void *)) instead of num_possible_cpus()*4
- *
- * This pcounter implementation is an abstraction to be able to use
- * either a static or a dynamic per cpu variable.
- * One dynamic per cpu variable gets a fast & cheap implementation, we can
- * change pcounter implementation too.
