2016-06-21Merge branch 'dsa-mv88e6xxx-probe-compatible'David S. Miller
Vivien Didelot says: ==================== net: dsa: mv88e6xxx: probe compatible This patchset factorizes the legacy and new SMI probing and abstracts the switch register accesses. This simplifies adding support for new chips or alternative register accesses. This will allow us to use a compatible chip info to describe how to access the SMI device and its switch ID register at probe time. For the legacy probe, we fix the compatible info to 88E6085. For the MDIO probe, we will use the compatible info from the device node data. All patches are reviewed. Changes since v4: - fix debug printing (was 'val' instead of '*val') Changes since v3 [3]: - better register access abstraction using the chip structure Changes since v2 [2]: - do not guess compatible model in legacy probe - add low level SMI API using a chip structure - allocate before probe and detection - add 3 cosmetic patches Changes since v1 [1]: - merge style fix from Ben Dooks - add Acked-by/Reviewed-by tags - drop one compatible string per model - detect the SMI device based on the compatible info - add an SMI ops structure [1] https://lkml.org/lkml/2016/6/8/1201 [2] https://lkml.org/lkml/2016/6/14/671 [3] https://lkml.org/lkml/2016/6/17/995 ==================== Signed-off-by: David S.

2016-06-21net: dsa: mv88e6xxx: abstract switch registers accessesVivien Didelot
When the SMI address of the switch chip is zero, the chip assumes to be the only one on the SMI master bus and thus responds to all its known SMI devices addresses (port registers, Global2, etc.) When its SMI address is not zero, some chips (e.g. 88E6352) use an indirect access through two SMI Command and Data registers. Other models (e.g. 88E6060) using less than 16 internal SMI addresses always use a direct access. Add a capability flag to describe chips supporting the (indirect) Multi-chip Addressing Mode, and a low-level API to access the registers via SMI. Other accesses (like Ethernet management frames) may be added later.

2016-06-20ftracetest: Fix hist unsupported result in hist selftestsSteven Rostedt (Red Hat)
When histograms are not configured in the kernel, the ftracetest histogram selftests should return "unsupported" and not "Failed". To detect this, the test scripts have: FEATURE=`grep hist events/sched/sched_process_fork/trigger` if [ -z "$FEATURE" ]; then echo "hist trigger is not supported" exit_unsupported fi The problem is that '-e' is in effect and any error will cause the program to terminate. The grep for 'hist' fails, because it is not compiled it (thus unsupported), but because grep has an error code for failing to find the string, it causes the program to terminate, and is marked as a failed test. Namhyung Kim recommended to test for the "hist" file located in events/sched/sched_process_fork/hist instead, as it is more inline with the other checks. As the hist file is only created if the histogram feature is enabled, that is a valid check.

2016-06-20tracing: Handle NULL formats in hold_module_trace_bprintk_format()Steven Rostedt (Red Hat)
If a task uses a non constant string for the format parameter in trace_printk(), then the trace_printk_fmt variable is set to NULL. This variable is then saved in the __trace_printk_fmt section. The function hold_module_trace_bprintk_format() checks to see if duplicate formats are used by modules, and reuses them if so (saves them to the list if it is new). But this function calls lookup_format() that does a strcmp() to the value (which is now NULL) and can cause a kernel oops. This wasn't an issue till 3debb0a9ddb ("tracing: Fix trace_printk() to print when not using bprintk()") which added "__used" to the trace_printk_fmt variable, and before that, the kernel simply optimized it out (no NULL value was saved). The fix is simply to handle the NULL pointer in lookup_format() and have the caller ignore the value if it was NULL.

So I _should_ have looked at other unserialized users of ->load_avg, but alas. Luckily nikbor reported a similar /0 from task_h_load() which instantly triggered recollection of this here problem. Aside from the intermediate value hitting memory and causing problems, there's another problem: the underflow detection relies on the signed bit. This reduces the effective width of the variables, IOW its effectively the same as having these variables be of signed type. This patch changes to a different means of unsigned underflow detection to not rely on the signed bit. This allows the variables to use the 'full' unsigned range. And it does so with explicit LOAD - STORE to ensure any intermediate value will never be visible in memory, allowing these unserialized loads. Note: GCC generates crap code for this, might warrant a look later. Note2: I say 'full' above, if we end up at U*_MAX we'll still explode; maybe we should do clamping on add too.

There are two generics functions phy_ethtool_{get|set}_link_ksettings, so we can use them instead of defining the same code in the driver. Signed-off-by: Philippe Reynes <tremyfr@gmail.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-19net: ethernet: bcmsysport: use phydev from struct net_devicePhilippe Reynes
The private structure contain a pointer to phydev, but the structure net_device already contain such pointer. So we can remove the pointer phydev in the private structure, and update the driver to use the one contained in struct net_device.

Yuval Mintz says: ==================== qed*: Fixes series This series contains several small fixes to driver behavior [4th patch is the only one containing a 'fatal' fix, but the error is only theoretical for qede; if would require another protocol driver yet unsubmitted to reach it]. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-19qed: Add missing port-modeYuval Mintz
The 'MODULE_FIBER' value replaced several other FIBER values in newer management firmware images, so existing code would fail to properly reflect its mode. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-19qed: Fix returning unlimited SPQ entriesYuval Mintz
Driver has 2 sets of entries for handling ramrod configurations toward firmware - a regular pre-allocated set of entires and a possible 'unlimited' list of additional pending entries. In most scenarios the 'unlimited' list would not be used, but when it does the handling of the ramrod completion doesn't properly handle the release of the entry.

2016-06-19qed*: Don't reset statistics on inner reloadYuval Mintz
Several user APIs can cause driver to perform an inner-reload. Currently, doing this would cause the HW/FW statistics of the adapter to reset, which isn't the expected behavior [statistics should only reset on explicit unloads].

2016-06-19qed: Prevent VF from Tx-switching 'promisc'Yuval Mintz
Internal loopback in driver is based on two things - first is the willingness of transmitter to use it [in case of VFs, this can be forced based on VEPA/VEB] and secondly on another vport classification configuration which should match the packet's destination. Current code allows non-linux VFs to configure a 'promisc' mode on Tx, meaning all traffic sent by VF would be loopbacked internally by firmware; This isn't considered a valid mode and as such should be prevented by PF.

2016-06-19qed: Correct default vlan behaviorYuval Mintz
When no vlan filter is configured, firmware has a configurable default on whether to pass only untagged packets or all packets regardless of their tagging. Driver currently doesn't set this field in the necessary ramrod, causing the default to always be 'receive all'. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S.

Without this the devices may not work correctly after some time of use because of asymmetric aging. And related to this, let's also remove the unusable states. - Always select omap interconnect for am43x as otherwise the am43x only configurations will not boot properly. This can happen easily for any product kernels that leave out other SoCs to save memory. - Fix DSS PLL2 addresses that have gone unused for now - Select erratum 430973 for omap3, this is now safe to do and can save quite a bit of debugging time for people who may have left it out. * tag 'omap-for-v4.7/fixes-powedomain' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP: DRA7: powerdomain data: Remove unused pwrsts_mem_ret ARM: OMAP: DRA7: powerdomain data: Remove unused pwrsts_logic_ret ARM: OMAP: DRA7: powerdomain data: Set L3init and L4per to ON ARM: OMAP2+: Select OMAP_INTERCONNECT for SOC_AM43XX ARM: dts: DRA74x: fix DSS PLL2 addresses ARM: OMAP2: Enable Errata 430973 for OMAP3 + Linux 4.7-rc2 Signed-off-by: Olof Johansson <olof@lixom.net>
