The commit "alpha: teach the compiler that BUG doesn't return"
(ed6b9b97f4) moved the asm code into inline
function which takes __FILE__ and __LINE__ as arguments. This violates
asm constrains there ("i" - an immediate operand with constant value), so
that compile may result in warning or error, depending on compiler
version.
Just adding an infinite loop to the BUG() is sufficient.
