net, lib: kill arch_fast_hash library bits

2014-12-10T20:17:46+00:00

As there are now no remaining users of arch_fast_hash(), lets kill
it entirely.

This basically reverts commit 71ae8aac3e19 ("lib: introduce arch
optimized hash library") and follow-up work, that is f.e., commit
237217546d44 ("lib: hash: follow-up fixups for arch hash"),
commit e3fec2f74f7f ("lib: Add missing arch generic-y entries for
asm-generic/hash.h") and last but not least commit 6a02652df511
("perf tools: Fix include for non x86 architectures").

irq_work: Introduce arch_irq_work_has_interrupt()

2014-09-13T16:38:07+00:00

The nohz full code needs irq work to trigger its own interrupt so that
the subsystem can work even when the tick is stopped.

Lets introduce arch_irq_work_has_interrupt() that archs can override to
tell about their support for this ability.

locking/mcs: Allow architecture specific asm files to be used for contended case

2014-02-09T20:18:52+00:00

This patch allows each architecture to add its specific assembly optimized
arch_mcs_spin_lock_contended and arch_mcs_spinlock_uncontended for
MCS lock and unlock functions.

locking/mcs: Order the header files in Kbuild of each architecture in alphabetical order

2014-02-09T20:17:50+00:00

We perform a clean up of the Kbuid files in each architecture.
We order the files in each Kbuild in alphabetical order
by running the below script.

for i in arch/*/include/asm/Kbuild
do
        cat $i | gawk '/^generic-y/ {
                i = 3;
                do {

                                        i = 1;
                                        continue;

                        break;

        END {
                n = asort(hdr);
                for (i = 1; i <= n; i++)
                        print "generic-y += " hdr[i];
        }' > ${i}.sorted;
        mv ${i}.sorted $i;

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next

2014-01-25T19:17:34+00:00

Pull networking updates from David Miller:

 1) BPF debugger and asm tool by Daniel Borkmann.

 2) Speed up create/bind in AF_PACKET, also from Daniel Borkmann.

 3) Correct reciprocal_divide and update users, from Hannes Frederic
    Sowa and Daniel Borkmann.

 4) Currently we only have a "set" operation for the hw timestamp socket
    ioctl, add a "get" operation to match.  From Ben Hutchings.

 5) Add better trace events for debugging driver datapath problems, also
    from Ben Hutchings.

 6) Implement auto corking in TCP, from Eric Dumazet.  Basically, if we
    have a small send and a previous packet is already in the qdisc or
    device queue, defer until TX completion or we get more data.

 7) Allow userspace to manage ipv6 temporary addresses, from Jiri Pirko.

 8) Add a qdisc bypass option for AF_PACKET sockets, from Daniel
    Borkmann.

 9) Share IP header compression code between Bluetooth and IEEE802154
    layers, from Jukka Rissanen.

10) Fix ipv6 router reachability probing, from Jiri Benc.

11) Allow packets to be captured on macvtap devices, from Vlad Yasevich.

12) Support tunneling in GRO layer, from Jerry Chu.

13) Allow bonding to be configured fully using netlink, from Scott
    Feldman.

14) Allow AF_PACKET users to obtain the VLAN TPID, just like they can
    already get the TCI.  From Atzm Watanabe.

15) New "Heavy Hitter" qdisc, from Terry Lam.

16) Significantly improve the IPSEC support in pktgen, from Fan Du.

17) Allow ipv4 tunnels to cache routes, just like sockets.  From Tom
    Herbert.

18) Add Proportional Integral Enhanced packet scheduler, from Vijay
    Subramanian.

19) Allow openvswitch to mmap'd netlink, from Thomas Graf.

20) Key TCP metrics blobs also by source address, not just destination
    address.  From Christoph Paasch.

21) Support 10G in generic phylib.  From Andy Fleming.

22) Try to short-circuit GRO flow compares using device provided RX
    hash, if provided.  From Tom Herbert.

The wireless and netfilter folks have been busy little bees too.

arch: Re-sort some Kbuild files to hopefully help avoid some conflicts

2014-01-14T05:56:54+00:00

Checkin:

    93ea02bb8435 arch: Clean up asm/barrier.h implementations using asm-generic/barrier.h

... unfortunately left some Kbuild files out of order, which caused
unnecessary merge conflicts, in particular with checkin:

    e3fec2f74f7f lib: Add missing arch generic-y entries for asm-generic/hash.h

Put them back in order to make the upcoming merges cleaner.
