From: Jan Beulich <jbeulich@xxxxxxxxxx> Due to the addition of __attribute__((__cold__)) to a few symbols without adjusting the linker scripts, those symbols currently may end up outside the [_stext,_etext) range, as they get placed in .text.unlikely by (at least) gcc 4.3.0. This may confuse code not only outside of the kernel, symbol_put_addr()'s BUG() could also trigger. Hence we need to add .text.unlikely (and for future uses of __attribute__((__hot__)) also .text.hot) to the TEXT_TEXT() macro. Issue observed by Lukas Lipavsky.
