Add a polarity cell for reset line specifier. If the reset line
is asserted when the register bit is 1, the polarity is
normal. Otherwise, it is inverted.

In rb_alloc_aux_page(), a page order is set to MAX_ORDER when order is
greater than MAX_ORDER, but page order should be less than MAX_ORDER,
therefore alloc_pages_node fails at least once. This patch fixes page
order so that it can be always less than MAX_ORDER.

At least on powerpc with GCC 6, the compiler is smart enough to optimise
lkdtm_CORRUPT_STACK() into an empty function that just returns.
If we print the buffer after we've written to it that prevents the
compiler from optimising away data and the memset().

What makes it so bad? (honest question) . Some alternatives:

I have a Linux kernel 4.4 system hosting a number of kvm VMs. Physical
interface eth0 connects to an 802.1Q trunk port on an external switch. Each VM
has a virtual interface (e1000 or virtio-net) connected to the physical NIC
through a macvtap interface and a VLAN interface; traffic between the

I don't know if it s a really great idea to use atomic bit ops for
things that do not need to be atomic.. It makes the lo

Check if basic LLVM compiling environment is ready.
Use llvm-config to detect include and library directories. Avoid using
'llvm-config --cxxflags' because its result contain some unwanted flags
like --sysroot (if LLVM is built by yocto).
Use '?=' to set LLVM_CONFIG, so explicitly passing LLVM_CO

Perf hooks allow hooking user code at perf events. They can be used for
manipulation of BPF maps, taking snapshot and reporting results. In this
patch two perf hook points are introduced: record_start and record_end.
To avoid buggy user actions, a SIGSEGV signal handler is introduced into
