2017-02-15x86/platform/goldfish: Prevent unconditional loadingThomas Gleixner1-0/+4
The goldfish platform code registers the platform device unconditionally which causes havoc in several ways if the goldfish_pdev_bus driver is enabled: - Access to the hardcoded physical memory region, which is either not available or contains stuff which is completely unrelated. - Prevents that the interrupt of the serial port can be requested - In case of a spurious interrupt it goes into a infinite loop in the interrupt handler of the pdev_bus driver (which needs to be fixed seperately). Add a 'goldfish' command line option to make the registration opt-in when the platform is compiled in. I'm seriously grumpy about this engineering trainwreck, which has seven SOBs from Intel developers for 50 lines of code. And none of them figured out that this is broken. Impressive fail!

Add new entry to the RDMA-CM configfs that allows users to select default TOS for RDMA-CM QPs. This is useful for users that want to control the TOS for legacy applications without changing their code. Application that sets the TOS explicitly using the rdma_set_option API will continue to work as expected, meaning overriding the configfs value.

2017-02-15jump_label: Reduce the size of struct static_keyJason Baron1-1/+3
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>

2017-02-14spi: lantiq-ssc: add support for Lantiq SSC SPI controllerHauke Mehrtens1-0/+29
This driver supports the Lantiq SSC SPI controller in master mode. This controller is found on Intel (former Lantiq) SoCs like the Danube, Falcon, xRX200, xRX300. The hardware uses two hardware FIFOs one for received and one for transferred bytes. When the driver writes data into the transmit FIFO the complete word is taken from the FIFO into a shift register. The data from this shift register is then written to the wire. This driver uses the interrupts signaling the status of the FIFOs and not the shift register. It is also possible to use the interrupts for the shift register, but they will send a signal after every word. When using the interrupts for the shift register we get a signal when the last word is written into the shift register and not when it is written to the wire. After all FIFOs are empty the driver busy waits till the hardware is not busy any more and returns the transfer status.

2017-02-14cdrom: Make device operations read-onlyKees Cook1-8/+1
Since function tables are a common target for attackers, it's best to keep them in read-only memory. As such, this makes the CDROM device ops tables const. This drops additionally n_minors, since it isn't used meaningfully, and sets the only user of cdrom_dummy_generic_packet explicitly so the variables can all be const.

This reverts 'commit 7e0739cd9c40 ("[media] videodev2.h: fix sYCC/AdobeYCC default quantization range"). The problem is that many drivers can convert R'G'B' content (often from sensors) to Y'CbCr, but they all produce limited range Y'CbCr. To stay backwards compatible the default quantization range for sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full range, even though the corresponding standards specify full range.

Many Motorola phones like droid 4 are using a custom PMIC called CPCAP or 6556002. We can support it's core features quite easily with regmap_spi and regmap_irq. The children of cpcap, such as regulators, ADC and USB, can be just regular device drivers and defined in the dts file. They get probed as we call of_platform_populate() at the end of our probe, and then the children can just call dev_get_regmap(dev.parent, NULL) to get the regmap.
