The value passed is 0 in all but "it can never happen" cases (and those only in a couple of drivers) *and* it would've been lost on the way out anyway, even if something tried to pass something meaningful. Just don't bother. Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

Pull single_open() leak fixes from Al Viro: "A bunch of fixes for a moderately common class of bugs: file with single_open() done by its ->open() and seq_release as its ->release(). That leaks; fortunately, it's not _too_ common (either people manage to RTFM that says "When using single_open(), the programmer should use single_release() instead of seq_release() in the file_operations structure to avoid a memory leak", or they just copy a correct instance), but grepping through the tree has caught quite a pile. All of that is, AFAICS, -stable fodder, for as far as the patches apply.

Merge ipc fixes and cleanups from my IPC branch. The ipc locking has always been pretty ugly, and the scalability fixes to some degree made it even less readable. We had two cases of double unlocks in error paths due to this (one rcu read unlock, one semaphore unlock), and this fixes the bugs I found while trying to clean things up a bit so that we are less likely to have more. * ipc-cleanups: ipc: simplify rcu_read_lock() in semctl_nolock() ipc: simplify semtimedop/semctl_main() common error path handling ipc: move sem_obtain_lock() rcu locking into the only caller ipc: fix double sem unlock in semctl error path ipc: move the rcu_read_lock() from sem_lock_and_putref() into callers ipc: sem_putref() does not need the semaphore lock any more ipc: move rcu_read_unlock() out of sem_unlock() and into callers

This is needed because when scan_of_devices finds the GAISLER_GPTIMER core that corresponds to the SMP "ticker" timer, the previously set proper irq flow handler gets overwritten with an incorrect one. This leads to very flaky timer interrupt handling on some hardware. Proper updates to handlers can still be done using leon_update_virq_handling.

With various straight RCU lock/unlock movements, one common exit path pattern had become rcu_read_unlock(); goto out_wakeup; and in fact there were no cases where we wanted to exit to out_wakeup _without_ releasing the RCU read lock. So replace that pattern with "goto out_rcu_wakeup", and remove the old out_wakeup.

sem_obtain_lock() was another of those functions that returned with the RCU lock held for reading in the success case. Move the RCU locking to the caller (semtimedop()), making it more obvious. We already did RCU locking elsewhere in that function. Side note: why does semtimedop() re-do the semphore lookup after the sleep, rather than just getting a reference to the semaphore it already looked up originally?

This is another ipc semaphore locking cleanup, trying to make the locking more straightforward. We move the rcu read locking into the callers of sem_lock_and_putref(), which in general means that we now mostly do the rcu_read_lock() and rcu_read_unlock() in the same function. Mostly. We still have the ipc_addid/newary/freeary mess, and things like ipcctl_pre_down_nolock().
