2011-01-26console: rename acquire/release_console_sem() to console_lock/unlock()Torben Hohn
The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.

2011-01-26pps: claim parallel port exclusivelyAlexander Gordeev
Both pps_parport and pps_gen_parport are written in a way that they can't share a port with any other driver. This can result in locking up the process that loads modules or even the whole kernel if the modules are compiled in. Use PARPORT_FLAG_EXCL to indicate this.

2011-01-26parport: make lockdep happy with waitlist_lockAlexander Gordeev
parport_unregister_device() should never be used when interrupts are enabled in hardware and irq handler is registered so there is no need to disable interrupts when using waitlist_lock. But there is no way to explain this subtle semantics to lockdep analyzer. So disable interrupts here too to simplify things. The price is negligible.

2011-01-25PM / Runtime: Don't enable interrupts while running in_interruptAlan Stern
This patch (as1445) fixes a bug in the runtime PM core left over from the addition of the no_callbacks flag. If this flag is set then it is possible for rpm_suspend() to be called in_interrupt, so when releasing spinlocks it's important not to re-enable interrupts. To avoid an unnecessary save-and-restore of the interrupt flag, the patch also inlines a pm_request_idle() call. This fixes Bugzilla #27482. (The offending code was added in 2.6.37, so it's not necessary to apply this to any earlier stable kernels.)

2011-01-25drivers/video/bf537-lq035.c: Add missing IS_ERR testJulia Lawall
lcd_device_register may return ERR_PTR, so a check is added for this value before the dereference. All of the other changes reorganize the error handling code in this function to avoid duplicating all of it in the added case. In the original code, in one case, the global variable fb_buffer was set to NULL in error code that appears after this variable is initialized. This is done now in all error handling code that has this property. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier f; @@ f(...) { ... return ERR_PTR(...); } @@ identifier r.f, fld; expression x; statement S1,S2; @@ x = f(...) ... when != IS_ERR(x) ( if (IS_ERR(x) ||...)
