One of my tests compiles the kernel with gcc 4.5.3, and I hit the following build error: include/linux/semaphore.h: In function 'sema_init': include/linux/semaphore.h:35:17: error: unknown field 'val' specified in initializer include/linux/semaphore.h:35:17: warning: missing braces around initializer include/linux/semaphore.h:35:17: warning: (near initialization for '(anonymous).raw_lock.<anonymous>.val') I bisected it down to: 625e88be ("locking/qspinlock: Merge 'struct __qspinlock' into 'struct qspinlock'") ... which makes qspinlock have an anonymous union, which makes initializing it special for older compilers. By adding strategic brackets, it makes the build happy again.
