2017-07-19liquidio: lio_main: remove unnecessary static in setup_io_queues()Gustavo A. R. Silva1-2/+2
Remove unnecessary static on local variables cpu_id_modulus and cpu_id. Such variables are initialized before being used, on every execution path throughout the function. The static has no benefit and, removing it reduces the object file size. This issue was detected using Coccinelle and the following semantic patch: @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; In the following log you can see a significant difference in the object file size. Also, there is a significant difference in the bss segment. This log is the output of the size command, before and after the code change: before: text data bss dec hex filename 78689 15272 27808 121769 1dba9 drivers/net/ethernet/cavium/liquidio/lio_main.o after: text data bss dec hex filename 78667 15128 27680 121475 1da83 drivers/net/ethernet/cavium/liquidio/lio_main.o Signed-off-by: Gustavo A.

2017-07-19ISDN: eicon: switch to use native bitmapsAndy Shevchenko2-205/+58
Two arrays are clearly bit maps, so, make that explicit by converting to bitmap API and remove custom helpers. Note sig_ind() uses out of boundary bit to (looks like) protect against potential bitmap_empty() checks for the same bitmap. This patch removes that since: 1) that didn't guarantee atomicity anyway; 2) the first operation inside the for-loop is set bit in the bitmap (which effectively makes it non-empty); 3) group_optimization() doesn't utilize possible emptiness of the bitmap in question. Thus, if there is a protection needed it should be implemented properly. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Unconditional reset dwmac before HW init if reset controller is present. In existing implementation we reset dwmac only after second module probing: (module load -> unload -> load again [reset happens]) Now we reset dwmac at every module load: (module load [reset happens] -> unload -> load again [reset happens]) Also some reset controllers have only reset callback instead of assert + deassert callbacks pair, so handle this case.

2017-07-19PM / Domains: defer dev_pm_domain_set() until genpd->attach_dev succeeds if ↵Sudeep Holla1-4/+4
present If the genpd->attach_dev or genpd->power_on fails, genpd_dev_pm_attach may return -EPROBE_DEFER initially. However genpd_alloc_dev_data sets the PM domain for the device unconditionally. When subsequent attempts are made to call genpd_dev_pm_attach, it may return -EEXISTS checking dev->pm_domain without re-attempting to call attach_dev or power_on. platform_drv_probe then attempts to call drv->probe as the return value -EEXIST != -EPROBE_DEFER, which may end up in a situation where the device is accessed without it's power domain switched on.

2017-07-18mlxsw: spectrum_router: Reflect IPv6 neighbours to the deviceArkadi Sharshevsky1-3/+37
As with IPv4, listen to NEIGH_UPDATE events from the ndisc table and program relevant neighbours to the device's neighbour table. Note that neighbours with a link-local IP address aren't programmed, as packets with a link-local destination IP are trapped after LPM lookup and never reach the neighbour table.

Update the register, so the IPv6 neighbours could be programmed to the device's neighbour table.

2017-07-18mlxsw: spectrum_router: Configure RIFs based on IPv6 addressesArkadi Sharshevsky3-5/+84
When a netdev is configured with an IP address a router interface (RIF) should be configured for it in the device. Allow configuration of RIFs based on IPv6 address notifications as well as IPv4. Note that the RIF exists as long as an IP address is configured on the netdev, regardless of the address family.

2017-07-18mlxsw: spectrum_router: Flood unregistered multicast packets to routerIdo Schimmel1-0/+20
Up until now we only flooded broadcast packets to the router when an L3 interface was configured on top of a bridge. However, IPv6 Neighbour Discovery packets are trapped to the CPU inside the router and these can be sent with a multicast address. Flood unregistered multicast packets to the router port, so that relevant packets could be trapped there.

2017-07-18mlxsw: spectrum: Add support for IPv6 trapsArkadi Sharshevsky3-11/+53
Before we can start using IPv6, we need to trap certain control packets to the CPU. Among others, these include Neighbour Discovery, DHCP and neighbour misses.

If 'dma_set_mask_and_coherent()' fails, we must undo the previous 'pci_request_regions()' call. Adjust corresponding 'goto' to jump at the right place of the error handling path. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
