/**
* @file
* @brief Populated exception vector table
*
* Vector table with exceptions filled in. The reset vector is the system entry
* point, ie. the first instruction executed.
*
* The table is populated with all the system exception handlers. No exception
* should not be triggered until the kernel is ready to handle them.
*
* We are using a C file instead of an assembly file (like the ARM vector table)
* to work around an issue with the assembler where:
*
* .word <function>
*
* statements would end up with the two half-words of the functions' addresses
* swapped.
