5875032241 Fix kpatch-build failure with srpm on centos 
kpatch-build was failing on centos7 with

    mv: cannot stat '/home/vagrant/rpmbuild/BUILD/kernel-*/linux-3.10.0-229.el7.x86_64': No such file or directory

in the error log. This was due to the actual directory being named
linux-3.10.0-229.el7.centos.x86_64. This patch avoids this failure by
adding a wildcard before the arch.

abdaa96c18 readme: update dependencies for f21 
Change the supported Fedora version to F21 and add a new dependency.

For some reason, numactl-devel is needed by "rpmbuild -bp kernel", but
isn't detected by "yum-builddep kernel".

2d45022052 remove dracut integration 
Remove the dracut support for adding the kpatch modules to the
initramfs.  This creates a sizeable delay in installation time and
doesn't offer any added protect over just applying the patches at boot
time using a systemd service.  Additional, we are seeing more platforms,
namely atomic and netboot environments, where changing the initramfs
can't be done.

07fccdb577 change inst_symlink to inst for insmod 
Use "inst" instead of "inst_symlink" for insmod, since insmod might not
necessarily be a symlink on some distros.  inst_symlink is functionally
the same as inst, with an additional check to make sure that it's a
symlink (which we don't care about either way).

6cdb5011c5 fix dracut dependencies 
The "kpatch install" command is broken because the kpatch script has
some missing dependencies in the initramfs.  Make sure the new
dependencies (readelf and awk) are added to the initramfs.

6e67e57a42 wait for outstanding shadow variables free requests in kpatch_exit 
Unload of kpatch module (and kpatch_shadow_hash table) before
all shadow variables free requests are processed can lead to
kernel crash.

Add rcu_barrier() to kpatch_exit() to wait for all outstanding
RCU callbacks to complete.

ea819a18b0 warn detection fix 
The current WARN detection logic catches the majority of cases, but
there are still a lot of outliers which it doesn't catch (thanks, gcc).

I looked at a much larger sample of WARN calls and came up with a more
generic algorithm.
