Martin, Chen 3de433a3b1 rebase rt kernel patch to CentOS7.6 3.10.0-957.1.3
timer-Reduce-timer-migration-overhead-if-disabled.patch
timer-Minimize-nohz-off-overhead.patch
two patches already included in upgraded kernel
remove description in meta patch.

fix compile error in drbd_req.c for improper usage of
request queue API; fix warning in kernel/bpf/core.c
for implicit declaration trace call for CFLAG
-Werror-implicit-function-declaration.

remove patch change is_swiotlb_buffer in lib/swiotlb.c
As change already in new kernel code.

explicitly disable three config, CONFIG_TORTURE_TEST=n,
CONFIG_RCU_TORTURE_TEST=n, CONFIG_LOCK_TORTURE_TEST=n.
As torture.c, locktorture.c, rcutorture.c are introduced
by new kernel release, which request CONFIG_PERCPU_RWSEM
be enabled. But config file generated by merge
kernel-3.10.0-x86_64-rt.config in source rpm and
kernel-3.10.0-x86_64-rt.config.tis_extra in meta_patch,
disable CONFIG_PERCPU_RWSEM, which makes build error
with "undefined symbol". These three file are built to
generate one module for one upper layer torture test
tool, so explicitly disable these config.
