Before the patch, the flock flag could remain uninitialized for the
lifespan of the fuse_file allocation. Unless set to true in
fuse_file_flock(), it would remain in an indeterminate state until read in
an if statement in fuse_release_common(). This could consequently lead to
taking an unexpected branch in the code.
The bug was discovered by a runtime instrumentation designed to detect use
of uninitialized memory in the kernel.

Only read access is checked before this call.
Actually, at the moment this is not an issue, as every in-tree arch does
the same manual checks for VERIFY_READ vs VERIFY_WRITE, relying on the MMU
to tell them apart, but this wasn't the case in the past and may happen
again on some odd arch in the future.
If anyone cares about 3.7 and earlier, this is a security hole (untested)

The AMD pinctrl driver uses a chained interrupt to demultiplex the GPIO
interrupts. Kevin Vandeventer reported, that his new AMD Ryzen locks up
hard on boot when the AMD pinctrl driver is initialized. The reason is an
interrupt storm. It's not clear whether that's caused by hardware or
firmware or both.
Using chained interrupts on X86 is a dangerous endavour. If a system is
misconfigured or the hardware buggy there is no safety net to catch an
interrupt storm.
Convert the driver to use a regular interrupt for the demultiplex
handler. This allows the interrupt storm detector to catch the malfunction
and lets the system boot up.
This should be backported to stable because it's likely that more users run
into this problem as the AMD Ryzen machines are spreading.
