Summary The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all MCU-private functions begin with the name of the architecture, not up_. This PR addresses only these name changes for the ARM-private functions prototyped in arm_internal.h This change to the files only modifies the name of called functions. nxstyle fixes were made for all core architecture files. However, there are well over 5000 additional complaints from MCU drivers and board logic that are unrelated to to this change but were affected by the name change. It is not humanly possible to fix all of these. I ask that this change be treated like other cosmetic changes that we have done which do not require full nxstyle compliance. Impact There should be not impact of this change (other that one step toward more consistent naming). Testing stm32f4discovery:netnsh
