2016-12-09x86: Make E820_X_MAX unconditionally larger than E820MAXAlex Thorlton
It's really not necessary to limit E820_X_MAX to 128 in the non-EFI case. This commit drops E820_X_MAX's dependency on CONFIG_EFI, so that E820_X_MAX is always at least slightly larger than E820MAX. The real motivation behind this is actually to prevent some issues in the Xen kernel, where the XENMEM_machine_memory_map hypercall can produce an e820 map larger than 128 entries, even on systems where the original e820 table was quite a bit smaller than that, depending on how many IOAPICs are installed on the system.

2016-12-08md: separate flags for superblock changesShaohua Li
The mddev->flags are used for different purposes. There are a lot of places we check/change the flags without masking unrelated flags, we could check/change unrelated flags. These usage are most for superblock write, so spearate superblock related flags. This should make the code clearer and also fix real bugs.

2016-12-08net: xgene: move xgene_cle_ptree_ewdn data off stackArnd Bergmann
The array for initializing the cle is set up on the stack with almost entirely constant data and then passed to a function that converts it into HW specific bit patterns. With the latest addition, the size of this array has grown to the point that we get a warning about potential stack overflow in allmodconfig builds: xgene_enet_cle.c: In function ‘xgene_enet_cle_init’: xgene_enet_cle.c:836:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Looking a bit deeper at the usage, I noticed that the only modification of the data is in dead code, as we don't even use the cle module for phy_mode other than PHY_INTERFACE_MODE_XGMII. This means we can simply mark the structure constant and access it directly rather than passing the pointer down through another structure, making the code more efficient at the same time as avoiding the warning.

2016-12-08clk: add devm_get_clk_from_child() APIKuninori Morimoto
Some driver is using this type of DT bindings for clock (more detail, see ${LINUX}/Documentation/devicetree/bindings/sound/simple-card.txt). sound_soc { ... cpu { clocks = <&xxx>; ... }; codec { clocks = <&xxx>; ... }; }; Current driver in this case uses of_clk_get() for each node, but there is no devm_of_clk_get() today. OTOH, the problem of having devm_of_clk_get() is that it encourages the use of of_clk_get() when clk_get() is more desirable. Thus, this patch adds new devm_get_clk_from_chile() which explicitly reads as get a clock from a child node of this device. By this function, we can also use this type of DT bindings sound_soc { clocks = <&xxx>, <&xxx>; clock-names = "cpu", "codec"; clock-ranges; ... cpu { ... }; codec { ... }; }; Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> [sboyd@codeurora.org: Rename subject to clk + add API] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

2016-12-08clk: bcm: Make COMMON_CLK_IPROC into a libraryStephen Boyd
The broadcom clk driver Kconfig file selects and depends on the COMMON_CLK_IPROC config for different SoC specific drivers. Let's simplify this by always selecting the COMMON_CLK_IPROC config, turning it into a set of library code. We still want to retain the SoC specific options, so we leave those in place. Since we're here we also drop COMMON_CLK dependency because that's implicitly handled by including this file in drivers/clk/Kconfig in the right place and also make CLK_BCM_KONA default to y on the architecture it exists for instead of plain default y.

Some peripheral clocks, like the VEC (Video EnCoder) clock need to be set to a precise rate (in our case 108MHz). With the current implementation, where peripheral clocks are not allowed to forward rate change requests to their parents, it is impossible to match this requirement unless the bootloader has configured things correctly, or a specific rate has been assigned through the DT (with the assigned-clk-rates property).

2016-12-08clk: ti: omap36xx: Work around sprz319 advisory 2.1Richard Watts
The OMAP36xx DPLL5, driving EHCI USB, can be subject to a long-term frequency drift. The frequency drift magnitude depends on the VCO update rate, which is inversely proportional to the PLL divider. The kernel DPLL configuration code results in a high value for the divider, leading to a long term drift high enough to cause USB transmission errors. In the worst case the USB PHY's ULPI interface can stop responding, breaking USB operation completely. This manifests itself on the Beagleboard xM by the LAN9514 reporting 'Cannot enable port 2. Maybe the cable is bad?' in the kernel log. Errata sprz319 advisory 2.1 documents PLL values that minimize the drift. Use them automatically when DPLL5 is used for USB operation, which we detect based on the requested clock rate. The clock framework will still compute the PLL parameters and resulting rate as usual, but the PLL M and N values will then be overridden. This can result in the effective clock rate being slightly different than the rate cached by the clock framework, but won't cause any adverse effect to USB operation.

2016-12-08parisc: Fix TLB related boot crash on SMP machinesHelge Deller
At bootup we run measurements to calculate the best threshold for when we should be using full TLB flushes instead of just flushing a specific amount of TLB entries. This performance test is run over the kernel text segment. But running this TLB performance test on the kernel text segment turned out to crash some SMP machines when the kernel text pages were mapped as huge pages. To avoid those crashes this patch simply skips this test on some SMP machines and calculates an optimal threshold based on the maximum number of available TLB entries and number of online CPUs. On a technical side, this seems to happen: The TLB measurement code uses flush_tlb_kernel_range() to flush specific TLB entries with a page size of 4k (pdtlb 0(sr1,addr)). On UP systems this purge instruction seems to work without problems even if the pages were mapped as huge pages. But on SMP systems the TLB purge instruction is broadcasted to other CPUs. Those CPUs then crash the machine because the page size is not as expected. C8000 machines with PA8800/PA8900 CPUs were not affected by this problem, because the required cache coherency prohibits to use huge pages at all. Sadly I didn't found any documentation about this behaviour, so this finding is purely based on testing with phyiscal SMP machines (A500-44 and J5000, both were 2-way boxes).

2016-12-08firmware: Correct handling of fw_state_wait() return valueBjorn Andersson
When request_firmware() finds an already open firmware object it will wait for that object to become fully loaded and then check the status. As __fw_state_wait_common() succeeds the timeout value returned will be truncated in _request_firmware_prepare() and interpreted as -EPERM. Prior to "firmware: do not use fw_lock for fw_state protection" the code did test if we where in the "done" state before sleeping, causing this particular code path to succeed, in some cases. As the callers are interested in the result of the wait and not the remaining timeout the return value of __fw_state_wait_common() is changed to signal "done" or "error", which simplifies the logic in _request_firmware_load() as well.

2016-12-08staging: comedi: comedidev.h: Document usage of 'detach' handlerIan Abbott
Document when the "detach" handler function pointed to by the `detach` member of a `struct comedi_driver` is called by the comedi core, and how the "attach" and "auto_attach" handlers can defer clean-up to it when they return an error to the comedi core. This is already mentioned as part of the documentation for `comedi_auto_config()`, but is useful to document it for `struct comedi_driver` as well, since `comedi_auto_config()` is not usually called directly by low-level comedi drivers, and it is not called at all for "legacy" comedi devices that are configured manually.
