Update reserved function names starting with one underscore, replacing them as follows: '_k_' with 'z_' '_K_' with 'Z_' '_handler_' with 'z_handl_' '_Cstart' with 'z_cstart' '_Swap' with 'z_swap' This renaming is done on both global and those static function names in kernel/include and include/. Other static function names in kernel/ are renamed by removing the leading underscore. Other function names not starting with any prefix listed above are renamed starting with a 'z_' or 'Z_' prefix. Function names starting with two or three leading underscores are not automatcally renamed since these names will collide with the variants with two or three leading underscores. Various generator scripts have also been updated as well as perf, linker and usb files. These are drivers/serial/uart_handlers.c include/linker/kobject-text.ld kernel/include/syscall_handler.h scripts/gen_kobject_list.py scripts/gen_syscall_header.py Signed-off-by: Patrik Flykt <patrik.flykt@intel.com>

/**

|
* @brief ARM Cortex-M k_thread_abort() routine
|
|
*
|
|
* The ARM Cortex-M architecture provides its own k_thread_abort() to deal
|
|
* with different CPU modes (handler vs thread) when a thread aborts. When its
|
|
* entry point returns or when it aborts itself, the CPU is in thread mode and
|
|
* must call z_swap() (which triggers a service call), but when in handler
|
|
* mode, the CPU must exit handler mode to cause the context switch, and thus
|
|
* must queue the PendSV exception.
