Kernel Address sanitizer (KASan) is a dynamic memory error detector. It provides
fast and comprehensive solution for finding use-after-free and out-of-bounds

KASAN uses compile-time instrumentation for checking every memory access,
therefore GCC = v4.9.2 required.

Stack instrumentation allows to detect out of bounds
memory accesses for variables allocated on stack.
Compiler adds redzones around every variable on stack
and poisons redzones in function's prologue.
Such approach significantly increases stack usage,

KASan is a runtime memory debugger designed to find use-after-free
and out-of-bounds bugs.
Currently KASAN supported only for x86_64 architecture and requires kernel
to be build with SLUB allocator.
KASAN uses compile-time instrumentation for checking every memory access,
therefore you

Some combinations of architectures and interrupt controllers make it
possible for abitrary interrupt signals to be selectively made immune to
masking by local_irq_disable(). For example, on ARM platforms, many
interrupt controllers allow interrupts to be routed to FIQ rather than IRQ.

armv7pmu_disable_event() is called during irq handling. If irq handling
switches over to fiq then the spin locks in this function risk deadlock.
Both armv7_pmnc_disable_counter() and armv7_pmnc_disable_intens() are
unconditional co-processor writes. I haven't yet come up with an

This patch provides an implementation of irq_set_nmi_routing by
allowing SPIs to be switched between group 1 (IRQ) and group 0 (FIQ).
It also repaces the interface used between the default FIQ handler and
the GIC. These extensions are required in order to allow SPIs to be
acknowledged and
Using FIQ (if it is available) gives perf a better insight into the
system by allowing code run with interrupts disabled to be profiled.

This RFC is particularly for your attention since it results
directly from feedback I've received from both of you, albeit
quite a few months ago now.

Currently three clocks are implemented: CLOCK_REALITME = 0,

5 bits wide to allow for future extension to

These are in types.h but not in checkpatch, so add them
to checkpatch's ability to know types.
This can avoid false positives for code like:
