| | * soc: qcom: smd: Make callback pass channel referenceBjorn Andersson2016-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By passing the smd channel reference to the callback, rather than the smd device, we can open additional smd channels from sub-devices of smd devices. Also updates the two smd clients today found in mainline. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Andy Gross <andy.gross@linaro.org>

* | | bpf: arm64: remove callee-save registers use for tmp registersYang Shi2016-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current implementation of ARM64 eBPF JIT, R23 and R24 are used for tmp registers, which are callee-saved registers. This leads to variable size of JIT prologue and epilogue. The latest blinding constant change prefers to constant size of prologue and epilogue. AAPCS reserves R9 ~ R15 for temp registers which not need to be saved/restored during function call. So, replace R23 and R24 to R10 and R11, and remove tmp_used flag to save 2 instructions for some jited BPF program.

* | | asix: Fix offset calculation in asix_rx_fixup() causing slow transmissionsJohn Stultz2016-05-17

We found the issue also was reproducible on a x86_64 system, using a "high-speed" USB2.0 port but the throughput did not measurably drop (possibly due to the scp transfer being cpu bound on my slow test hardware). After lots of debugging, I found the check added in the problematic commit seems to be calculating the offset incorrectly. In the normal case, in the main loop of the function, we do: (where offset is zero, or set to "offset += (copy_length + 1) & 0xfffe" in the previous loop) rx->header = get_unaligned_le32(skb->data + offset); offset += sizeof(u32); But the problematic patch calculates: offset = ((rx->remaining + 1) & 0xfffe) + sizeof(u32); rx->header = get_unaligned_le32(skb->data + offset); Adding some debug logic to check those offset calculation used to find rx->header, the one in problematic code is always too large by sizeof(u32). Thus, this patch removes the incorrect " + sizeof(u32)" addition in the problematic calculation, and resolves the issue. Cc: Dean Jenkins <Dean_Jenkins@mentor.com> Cc: "David B.

* | | switchdev: pass pointer to fib_info instead of copyJiri Pirko2016-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that fib_info->nh is [0] so the struct fib_info allocation size depends on number of nexthops. If we just copy fib_info, we do not copy the nexthops info and driver accesses memory which is not ours. Given the fact that fib4 does not defer operations and therefore it does not need copy, just pass the pointer down to drivers as it was done before.

So, fix this by moving everything under the spinlock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make sure the socket for which the user is listing publication exists before parsing the socket netlink attributes. Prior to this patch a call without any socket caused a NULL pointer dereference in tipc_nl_publ_dump().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function setup_timer combines the initialization of a timer with the initialization of the timer's function and data fields. The mulitiline code for timer initialization is now replaced with function setup_timer. Also, quoting the mod_timer() function comment: -> mod_timer() is a more efficient way to update the expire field of an active timer (if the timer is inactive it will be activated). Use setup_timer() and mod_timer() to setup and arm a timer, making the code compact and aid readablity. Signed-off-by: Muhammad Falak R Wani <falakreyaz@gmail.com> Signed-off-by: David S.

This lifts the restriction for the default mode; User should be able to start the maximum number of VFs as appear in the PCI config space.

Since the bulletin board is getting cleaned as part of the IOV disable flow on the PF side, re-enabling sriov would lead to a VF that sees the carrier as 'down', until an event causing the PF to re-fill the bulletin with the link configuration would occur. To fix this we simply refelect the link state during the flows, giving the later VFs a default reflecting the PFs link state.
