2018-09-12give up on gcc ilog2() constant optimizationsLinus Torvalds
gcc-7 has an "optimization" pass that completely screws up, and generates the code expansion for the (impossible) case of calling ilog2() with a zero constant, even when the code gcc compiles does not actually have a zero constant. And we try to generate a compile-time error for anybody doing ilog2() on a constant where that doesn't make sense (be it zero or negative). So now gcc7 will fail the build due to our sanity checking, because it created that constant-zero case that didn't actually exist in the source code. There's a whole long discussion on the kernel mailing about how to work around this gcc bug. The gcc people themselevs have discussed their "feature" in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=72785 but it's all water under the bridge, because while it looked at one point like it would be solved by the time gcc7 was released, that was not to be. So now we have to deal with this compiler braindamage. And the only simple approach seems to be to just delete the code that tries to warn about bad uses of ilog2(). So now "ilog2()" will just return 0 not just for the value 1, but for any non-positive value too. It's not like I can recall anybody having ever actually tried to use this function on any invalid value, but maybe the sanity check just meant that such code never made it out in public.

2017-03-31drivers/base: add bus for System-on-Chip devicesLee Jones
Traditionally, any System-on-Chip based platform creates a flat list of platform_devices directly under /sys/devices/platform. In order to give these some better structure, this introduces a new bus type for soc_devices that are registered with the new soc_device_register() function. All devices that are on the same chip should then be registered as child devices of the soc device. The soc bus also exports a few standardised device attributes which allow user space to query the specific type of soc.

2016-09-29compiler-gcc.h: Add gcc-recommended GCC_VERSION macroDaniel Santos
Throughout compiler*.h, many version checks are made. These can be simplified by using the macro that gcc's documentation recommends. However, my primary reason for adding this is that I need bug-check macros that are enabled at certain gcc versions and it's cleaner to use this macro than the tradition method: #if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ => 2) If you add patch level, it gets this ugly: #if __GNUC__ > 4 || (__GNUC__ == 4 && (__GNUC_MINOR__ > 2 || \ __GNUC_MINOR__ == 2 __GNUC_PATCHLEVEL__ >= 1)) As opposed to: #if GCC_VERSION >= 40201 While having separate headers for gcc 3 & 4 eliminates some of this verbosity, they can still be cleaned up by this.

2016-09-29ftrace: Make all inline tags also include notraceSteven Rostedt
Commit 5963e317b1e9d2a ("ftrace/x86: Do not change stacks in DEBUG when calling lockdep") prevented lockdep calls from the int3 breakpoint handler from reseting the stack if a function that was called was in the process of being converted for tracing and had a breakpoint on it. The idea is, before calling the lockdep code, do a load_idt() to the special IDT that kept the breakpoint stack from reseting. This worked well as a quick fix for this kernel release, until a certain config caused a lockup in the function tracer start up tests. Investigating it, I found that the load_idt that was used to prevent the int3 from changing stacks was itself being traced! Even though the config had CONFIG_OPTIMIZE_INLINING disabled, and all 'inline' tags were set to always inline, there were still cases that it did not inline! This was caused by CONFIG_PARAVIRT_GUEST, where it would add a pointer to the native_load_idt() which made that function to be traced. Commit 45959ee7aa645815a ("ftrace: Do not function trace inlined functions") only touched the 'inline' tags when CONFIG_OPMITIZE_INLINING was enabled. PARAVIRT_GUEST shows that this was not enough and we need to also mark always_inline with notrace as well.

2016-09-29ftrace: Do not function trace inlined functionsSteven Rostedt
When gcc inlines a function, it does not mark it with the mcount prologue, which in turn means that inlined functions are not traced by the function tracer. But if CONFIG_OPTIMIZE_INLINING is set, then gcc is allowed not to inline a function that is marked inline. Depending on the options and the compiler, a function may or may not be traced by the function tracer, depending on whether gcc decides to inline a function or not. This has caused several problems in the pass becaues gcc is not always consistent with what it decides to inline between different gcc versions. Some places should not be traced (like paravirt native_* functions) and these are mostly marked as inline. When gcc decides not to inline the function, and if that function should not be traced, then the ftrace function tracer will suddenly break when it use to work fine. This becomes even harder to debug when different versions of gcc will not inline that function, making the same kernel and config work for some gcc versions and not work for others. By making all functions marked inline to not be traced will remove the ambiguity that gcc adds when it comes to tracing functions marked inline. All gcc versions will be consistent with what functions are traced and having volatile working code will be removed. Note, only the inline macro when CONFIG_OPTIMIZE_INLINING is set needs to have notrace added, as the attribute __always_inline will force the function to be inlined and then not traced.

2014-05-28mmc: sdhci: add quirk for lack of 1.8v supportJeetesh Burman
The OLPC XO-1.75 laptop includes a SDHCI controller which is 1.8v capable, and it truthfully reports so in its capabilities. This alternate voltage is used for driving new "UHS-I" SD cards at their full speed. However, what the controller doesn't know is that the motherboard physically doesn't have a 1.8v supply available. Add a quirk so that systems such as this one can override disable 1.8v support, adding support for UHS-I cards (by running them at 3.3v). This avoids a problem where the system would first try to run the card at 1.8v, fail, and then not be able to fully reset the card to retry at the normal 3.3v voltage. This is more appropriate than using the MISSING_CAPS quirk, which is intended for cases where the SDHCI controller is actually lying about its capabilities, and would force us to somehow override both caps words from another source.

2014-03-31ethtool: Introduce a method for getting time stamping capabilities.Richard Cochran
This commit adds a new ethtool ioctl that exposes the SO_TIMESTAMPING capabilities of a network interface. In addition, user space programs can use this ioctl to discover the PTP Hardware Clock (PHC) device associated with the interface. Since software receive time stamps are handled by the stack, the generic ethtool code can answer the query correctly in case the MAC or PHY drivers lack special time stamping features.

2014-03-31ethtool: Centralise validation of ETHTOOL_{G, S}RXFHINDIR parametersBen Hutchings
Add a new ethtool operation (get_rxfh_indir_size) to get the indirectional table size. Use this to validate the user buffer size before calling get_rxfh_indir or set_rxfh_indir. Use get_rxnfc to get the number of RX rings, and validate the contents of the new indirection table before calling set_rxfh_indir. Remove this validation from drivers.

2014-01-29input: touchscreen: added platform data for Fusion touchscreenStefan Agner
Added platform data struct to define interrupt and reset GPIO. This allows to initialize the touchscreen controller inside the driver rather then in each platform and use the driver as a module.
2013-12-09mfd: stmpe: add ADC block resourcesStefan Agner
In order to use the auxiliar ADC inputs of STMPE811 devices we need to add resources for the ADC block. Also move the ADC macros from the touchscreen driver to the general header file. We will need them for the ADC driver in future.
2013-07-05UBI: document UBI_IOCVOLUP better in user headerMike Frysinger
The current ioctl define implies that this func expects to be passed a 64bit number directly rather than a pointer to a 64bit. The code that processes this ioctl shows that it clearly expects a pointer. It'd be best if we could change the type to "__s64*", but that would change the generated ioctl number thus breaking the userland ABI. So just add a comment for intrepid developers.

2013-04-18mmc: sdhci: add quirk for lack of 1.8v supportDaniel Drake
The OLPC XO-1.75 laptop includes a SDHCI controller which is 1.8v capable, and it truthfully reports so in its capabilities. This alternate voltage is used for driving new "UHS-I" SD cards at their full speed. However, what the controller doesn't know is that the motherboard physically doesn't have a 1.8v supply available. Add a quirk so that systems such as this one can override disable 1.8v support, adding support for UHS-I cards (by running them at 3.3v). This avoids a problem where the system would first try to run the card at 1.8v, fail, and then not be able to fully reset the card to retry at the normal 3.3v voltage. This is more appropriate than using the MISSING_CAPS quirk, which is intended for cases where the SDHCI controller is actually lying about its capabilities, and would force us to somehow override both caps words from another source.
