Where did this piece move in the new code?
- /* Clear MSR:EE */
- mfmsr r7
- rlwinm r0,r7,0,17,15
- mtmsr r0
-
- /* Check current_thread_info()->flags */
- rlwinm r4,r1,0,0,18
- lwz r4,TI_FLAGS(r4)
- andi. r0,r4,_TIF_NEED_RESCHED
- beq 1f
- mtmsr r7 /* out of line this ? */
- blr
-1:
Maybe this code was added back somewhere else in another commit around the
