2022-03-13Kbuild: move to -std=gnu11Arnd Bergmann4-9/+7
During a patch discussion, Linus brought up the option of changing the C standard version from gnu89 to gnu99, which allows using variable declaration inside of a for() loop. While the C99, C11 and later standards introduce many other features, most of these are already available in gnu89 as GNU extensions as well. An earlier attempt to do this when gcc-5 started defaulting to -std=gnu11 failed because at the time that caused warnings about designated initializers with older compilers. Now that gcc-5.1 is the minimum compiler version used for building kernels, that is no longer a concern. Similarly, the behavior of 'inline' functions changes between gnu89 using gnu_inline behavior and gnu11 using standard c99+ behavior, but this was taken care of by defining 'inline' to include __attribute__((gnu_inline)) in order to allow building with clang a while ago. Nathan Chancellor reported a new -Wdeclaration-after-statement warning that appears in a system header on arm, this still needs a workaround. The differences between gnu99, gnu11, gnu1x and gnu17 are fairly minimal and mainly impact warnings at the -Wpedantic level that the kernel never enables. Between these, gnu11 is the newest version that is supported by all supported compiler versions, though it is only the default on gcc-5, while all other supported versions of gcc or clang default to gnu1x/gnu17.

2022-03-11nvdimm/blk: Delete the block-aperture window driverDan Williams1-315/+85
Block Aperture Window support was an attempt to layer an error model over PMEM for platforms that did not support machine-check-recovery. However, it was abandoned before it ever shipped, and only ever existed in the ACPI specification. Meanwhile Linux has carried a large pile of dead code for non-shipping infrastructure. For years it has been off to the side out of the way, but now CXL and recent directions with DAX support have the potential to collide with this code. In preparation for adding discontiguous namespace support, a pre-requisite for the nvdimm subsystem to replace device-mapper for striping + concatenation use cases, delete BLK aperture support. On the obscure chance that some hardware vendor shipped support for this mode, note that the driver will still keep BLK space reserved in the label area. So an end user in this case would still have the opportunity to report the regression to get BLK-mode support restored without risking the data they have on that device.

2022-03-11remoteproc: Change rproc_shutdown() to return a statusSuman Anna1-1/+2
The rproc_shutdown() function is currently not returning any error code, and any failures within rproc_stop() are not passed back to the users. Change the signature to return a success value back to the callers. The remoteproc sysfs and cdev interfaces are also updated to return back this status to userspace.

2022-03-11dt-bindings: kbuild: Use DTB files for validationRob Herring2-16/+8
Switch the DT validation to use DTB files directly instead of a DTS to YAML conversion. The original motivation for supporting validation on DTB files was to enable running validation on a running system (e.g. 'dt-validate /sys/firmware/fdt') or other cases where the original source DTS is not available. The YAML format was not without issues. Using DTBs with the schema type information solves some of those problems. The YAML format relies on the DTS source level information including bracketing of properties, size directives, and phandle tags all of which are lost in a DTB file. While standardizing the bracketing is a good thing, it does cause a lot of extra warnings and churn to fix them. Another issue has been signed types are not validated correctly as sign information is not propagated to YAML. Using the schema type information allows for proper handling of signed types. YAML also can't represent the full range of 64-bit integers as numbers are stored as floats by most/all parsers. The DTB validation works by decoding property values using the type information in the schemas themselves. The main corner case this does not work for is matrix types where neither dimension is fixed. For now, checking the dimensions in these cases are skipped.

2022-03-11tracing: Add snapshot at end of kernel boot upSteven Rostedt (Google)1-0/+8
Add ftrace_boot_snapshot kernel parameter that will take a snapshot at the end of boot up just before switching over to user space (it happens during the kernel freeing of init memory). This is useful when there's interesting data that can be collected from kernel start up, but gets overridden by user space start up code. With this option, the ring buffer content from the boot up traces gets saved in the snapshot at the end of boot up. This trace can be read from: /sys/kernel/tracing/snapshot Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org>

2022-03-11dt-bindings: mmc: sunxi: add Allwinner F1c100s compatibleJesse Taube1-0/+3
The Allwinner F1C100 series contains two MMC controller blocks. From comparing the data sheets, they seem to be compatible with the one used in the Allwinner A20: the register layout is the same, and they use the same separate sample and output clocks design. The only difference is the missing reset line in the A20 version, but both the binding and the Linux driver make this optional, so it's still a fit. Add the new SoC specific name and require it to be paired with the A20 fallback name, as this is all the driver needs to care about.

2022-03-11dt-bindings: kbuild: Pass DT_SCHEMA_FILES to dt-validateRob Herring1-25/+3
In preparation for supporting validation of DTB files, the full processed schema will always be needed in order to extract type information from it. Therefore, the processed schema containing only what DT_SCHEMA_FILES specifies won't work. Instead, dt-validate has gained an option, -l or --limit, to specify which schema(s) to use for validation. As the command line option is new, we the minimum dtschema version must be updated.
