PR-957 PR-947 PR-963 PR-969 Provide Provide nx_ versions of many functions that are used internally to avoid disrupting errno in userspace

PR-965 PR-980 PR-984 ioctl is now always in the variadic form syscalls in KERNEL builds are also more efficent with this as well now.

...

1. Any thread may query its own stack,
2. A kernel thread may query the stack of any other thread
3. Application threads, however, may query only the stacks of threads within the same task group, i.e., the main thread and any of the child pthreads created with the main thread as a parent or grandparent or great-grandparent.

PR-1104 Internal function fs_fsopen() no longer affects errno

Bug Fixes

Many private architecture interfaces were using 'up_' instead of the arch name 'arm_'

PR-1018 PR-1017 PR-1021 PR-1022 PR-1057 PR-1060 Clean up internal APIs that were not using the propery naming conventions

...

This removes support for the Codesourcery, Atollic, DevKitArm, Raisonance, and CodeRed toolchains. Not only are these tools old and no longer used but they are all equivalent to the standard ARM EABI toolchains. Retaining specific support has not meaningful (and they are still supported, but now just as generic EABI toolchains).

Bug Fixes

Many small changes to resolve dependency resolution issues that would sometimes appear during parallel builds.  Parallel builds should be much more reliable now and bugs filed against any issues found.

PR-1000 Fix broken support of ZDS-II Toolchain with MSYS

...

• It was not possible to DMA to/from AXI sram if CONFIG_STM32H7_DMACAPABLE=y
• When doing TX DMA (e.g. in SPI driver in simplex-tx mode), it should not be necessary to
  align the data buffers to the cache line.
