Remove support for 'standalone' rseq registration
Depend on libc to handle the allocation and registration of the rseq
area for the whole process.
Librseq can still be built and run with a libc that lacks the rseq
symbols as it doesn't link on them directly but it will not handle the
registration even if the syscall is available.
User visible changes:
* Removes per-thread registration API, with libc the registration is
either enabled for all threads or none.

The following dependencies are optional:
./configure with --disable-numaThis source tree is based on the Autotools suite from GNU to simplify portability. Here are some things you should have on your system in order to compile the Git repository tree:
automake points to a recent version!)If you get the tree from the Git repository, you will need to run
./bootstrap
in its root. It calls all the GNU tools needed to prepare the tree configuration.
To build and install, do:
./configure make sudo make install sudo ldconfig
Note: the configure script sets /usr/local as the default prefix for files it installs. However, this path is not part of most distributions' default library path, which will cause builds depending on librseq to fail unless -L/usr/local/lib is added to LDFLAGS. You may provide a custom prefix to configure by using the --prefix switch (e.g., --prefix=/usr).
cd /path/to/kernel/sources make headers_install cd /path/to/librseq CPPFLAGS=-I/path/to/kernel/sources/usr/include ./configure make sudo make install sudo ldconfig
To run the test suite after a successful build:
make check
The default list of tests to run can be overriden by the TESTS variable:
make check TESTS="run_unregistered_test.tap"
