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>

* Drivers call this routine instead of IRQ_CONNECT() when interrupts are

* The Galileo board virtualizes IRQs as follows:

*
|
|
* - The first CONFIG_IOAPIC_NUM_RTES IRQs are provided by the IOAPIC so the
|
|
* IOAPIC is programmed for these IRQs
|
|
* - The remaining IRQs are provided by the LOAPIC and hence the LOAPIC is
|
|
* programmed.
