Cover letter [PATCH 0/3] serial: sysrq cleanup and stm32 fixes
The first patch cleans up the interrupt handlers that rely on deferred sysrq processing by not needlessly saving the interrupt state.
The second fixes the threaded interrupt handling of the stm32 driver and properly fixes a couple of deadlocks that were incidentally worked around by a recent commit.
The third patch cleans up the stm32 console implementation by switching to deferred sysrq processing, thereby making the console code more robust and allowing it to be used with PREEMPT_RT.
This series is against tty-next and and have only been compile tested.
