timers, driver/net/ethernet/tile: Initialize the egress timer as pinned

2016-07-07T08:25:14+00:00

Pinned timers must carry the pinned attribute in the timer structure
itself, so convert the code to the new API.

No functional change.

net: tilegx: use correct timespec64 type

2016-06-18T05:27:38+00:00

The conversion to the 64-bit time based ptp methods left two instances
of 'struct timespec' in place. This is harmless because 64-bit
architectures define timespec64 as timespec, and this driver is
not used on 32-bit machines.

However, using 'struct timespec64' directly is obviously the right
thing to do, and will help us remove 'struct timespec' in the future.

treewide: replace dev->trans_start update with helper

2016-05-04T18:16:49+00:00

Replace all trans_start updates with netif_trans_update helper.
change was done via spatch:

struct net_device *d;
@@
- d->trans_start = jiffies
+ netif_trans_update(d)

Compile tested only.

nohz: Prevent tilegx network driver interrupts

2015-07-29T13:44:59+00:00

Normally the tilegx networking shim sends irqs to all the cores
to distribute the load of processing incoming-packet interrupts,
so that you can get to multiple Gb's of traffic inbound.

However, in nohz_full mode we don't want to interrupt the
nohz_full cores by default, so we limit the set of cores we use
to only the online housekeeping cores.

To make client code easier to read, we introduce a new nohz_full
accessor, housekeeping_cpumask(), which returns a pointer to the
housekeeping_mask if nohz_full is enabled, and otherwise returns
the cpu_possible_mask.

net: batch of last_rx update avoidance in ethernet drivers.

None of those drivers uses last_rx for its own needs.

Merge tag 'cpumask-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux

2015-04-20T17:19:03+00:00

Pull final removal of deprecated cpus_* cpumask functions from Rusty Russell:
 "This is the final removal (after several years!) of the obsolete
  cpus_* functions, prompted by their mis-use in staging.

  With these function removed, all cpu functions should only iterate to
  nr_cpu_ids, so we finally only allocate that many bits when cpumasks
  are allocated offstack"

ptp: tilegx: convert to the 64 bit get/set time methods.

2015-03-31T16:01:18+00:00

This driver is 64 bit only, and so this driver and device are ready
for 2038.  This patch changes the driver to the new PHC and also
carries the timespec64 parameter on out to the gxio_mpipe_get-
set_timestamp functions, making explicit the fact that the tv_sec
field is 64 bits wide.

Not even compile tested.
