A bug fix to the MSIx handling in vfio added references to functions that may not be defined if MSI is disabled in the kernel, resulting in this link error: drivers/built-in.o: In function `vfio_msi_set_vector_signal': :(.text+0x450808): undefined reference to `get_cached_msi_msg' :(.text+0x45080c): undefined reference to `write_msi_msg' As suggested by Alex Williamson, add stub implementations for get_cached_msi_msg() and pci_write_msi_msg(). In case this bugfix gets backported, please note that the #ifdef has changed over time, originally both functions were implemented in drivers/pci/msi.c and controlled by CONFIG_PCI_MSI, while nowadays get_cached_msi_msg() is part of the generic MSI support and can be used without PCI.

2017-02-16async_tx: deprecate broken support for channel switchingDan Williams
Back in 2011, Russell pointed out that the "async_tx channel switch" capability was violating expectations of the dma mapping api [1]. At the time the existing uses were reviewed as still usable, but that longer term we needed a rework of the raid offload implementation. While some of the framework for a fixed implementation was introduced in 2012 [2], the wider rewrite never materialized. There continues to be interest in raid offload with new dma/raid engine drivers being submitted. Those drivers must not build on top of the broken channel switching capability. Prevent async_tx from using an offload engine if the channel switching capability is enabled. This still allows the engine to be used for other purposes, but the broken way async_tx uses these engines for raid will be disabled. For configurations where this causes a performance regression the only solution is to start the work of eliminating the async_tx api and moving channel management into the raid code directly where it can manage marshalling an operation stream between multiple dma channels.

2017-02-15jump_label: Reduce the size of struct static_keyJason Baron
The static_key->next field goes mostly unused. The field is used for associating module uses with a static key. Most uses of struct static_key define a static key in the core kernel and make use of it entirely within the core kernel, or define the static key in a module and make use of it only from within that module. In fact, of the ~3,000 static keys defined, I found only about 5 or so that did not fit this pattern. Thus, we can remove the static_key->next field entirely and overload the static_key->entries field. That is, when all the static_key uses are contained within the same module, static_key->entries continues to point to those uses. However, if the static_key uses are not contained within the module where the static_key is defined, then we allocate a struct static_key_mod, store a pointer to the uses within that struct static_key_mod, and have the static key point at the static_key_mod. This does incur some extra memory usage when a static_key is used in a module that does not define it, but since there are only a handful of such cases there is a net savings. In order to identify if the static_key->entries pointer contains a struct static_key_mod or a struct jump_entry pointer, bit 1 of static_key->entries is set to 1 if it points to a struct static_key_mod and is 0 if it points to a struct jump_entry. We were already using bit 0 in a similar way to store the initial value of the static_key. This does mean that allocations of struct static_key_mod and that the struct jump_entry tables need to be at least 4-byte aligned in memory. As far as I can tell all arches meet this criteria. For my .config, the patch increased the text by 778 bytes, but reduced the data + bss size by 14912, for a net savings of 14,134 bytes. text data bss dec hex filename 8092427 5016512 790528 13899467 d416cb vmlinux.pre 8093205 5001600 790528 13885333 d3df95 vmlinux.post Link: http://lkml.kernel.org/r/1486154544-4321-1-git-send-email-jbaron@akamai.com Cc: Peter Zijlstra <peterz@infradead.org> Cc: Ingo Molnar <mingo@kernel.org> Cc: Joe Perches <joe@perches.com> Signed-off-by: Jason Baron <jbaron@akamai.com> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>

2017-02-13rhashtable: Add nested tablesHerbert Xu
This patch adds code that handles GFP_ATOMIC kmalloc failure on insertion. As we cannot use vmalloc, we solve it by making our hash table nested. That is, we allocate single pages at each level and reach our desired table size by nesting them. When a nested table is created, only a single page is allocated at the top-level. Lower levels are allocated on demand during insertion. Therefore for each insertion to succeed, only two (non-consecutive) pages are needed. After a nested table is created, a rehash will be scheduled in order to switch to a vmalloced table as soon as possible. Also, the rehash code will never rehash into a nested table. If we detect a nested table during a rehash, the rehash will be aborted and a new rehash will be scheduled. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2017-02-13mmc: core: Invent MMC_CAP_3_3V_DDRUlf Hansson
According the JEDEC specification an eMMC card supporting 1.8V vccq in DDR mode should also be capable of 3.3V. However, it's been reported that some mmc hosts supports 3.3V, but not 1.8V. Currently the mmc core implements an error handling when the host fails to set 1.8V for vccq, by falling back to 3.3V. Unfortunate, this seems to be insufficient for some mmc hosts. To enable these to use eMMC DDR mode let's invent a new mmc cap, MMC_CAP_3_3V_DDR, which tells whether they support the eMMC 3.3V DDR mode. In case MMC_CAP_3_3V_DDR is set, but not MMC_CAP_1_8V_DDR, let's change to remain on the 3.3V, as it's the default voltage level for vccq, set by the earlier power up sequence. As this change introduces MMC_CAP_3_3V_DDR, let's take the opportunity to do some re-formatting of the related defines in the header file.

A significant amount of functions are available through the public mmc core.h header file. Let's slim down this public mmc interface, as to prevent users from abusing it, by moving some of the functions to private mmc header files. This change concentrates on moving the functions into private mmc headers, following changes may continue with additional clean-ups, as an example some functions can be turned into static.

2017-02-13mmc: core: First step in cleaning up public mmc header filesUlf Hansson
This is the first step in cleaning up the public mmc header files. In this change we makes sure each header file builds standalone, as that helps to resolve dependencies. While changing this, it also seems reasonable to stop including other headers from inside a header itself which it don't depend upon. Additionally, in some cases such dependencies are better resolved by forward declaring the needed struct.

2017-02-13mmc: mxcmmc: Include interrupt.h in the platform data headerUlf Hansson
The mxcmmc platform data header depends on interrupt.h. Don't rely on the public mmc header host.h to include it, bud instead make that dependency explicit. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2017-02-13mmc: dw_mmc: Remove the public dw_mmc header fileUlf Hansson
There are currently no external users of the public dw_mmc header file, except the dw_mmc driver itself. Therefore let's move the definitions from the public dw_mmc header file into the existing private dw_mmc header file and then remove the public one.

2017-02-13mmc: sh_mmcif: Remove unused clk_ctrl2_present from the platform dataUlf Hansson
There are currently no users of the clk_ctrl2_present member from the platform data, so let's remove it. Note, as some of the sh_mmcif variants may support clk_ctrl2, let's keep the current code in the driver, which deals with this. For future support, we should invent a DT binding instead, but let's leave that until it's needed.
