JFYI, the Blackfin cross-build fails with:
/home/mingo/tip/kernel/locking/rtmutex.c: In function 'rt_mutex_adjust_prio_chain': /home/mingo/tip/kernel/locking/rtmutex.c:739: error: unable to find a register to spill in class 'CCREGS' /home/mingo/tip/kernel/locking/rtmutex.c:739: error: this is the insn: (insn 82 75 107 2 /home/mingo/tip/kernel/locking/rtmutex.c:487 (set (reg:BI 186) (eq:BI (reg/v/f:SI 9 P1 [orig:85 top_waiter ] [85]) (const_int 0 [0x0]))) 111 {compare_eq} (nil)) /home/mingo/tip/kernel/locking/rtmutex.c:739: confused by earlier errors, bailing out
Thanks,
