Hi Linus Happy new year!
The following changes since commit 2595646791c319cadfdbf271563aac97d0843dc7: Linux 4.20-rc5 (2018-12-02 15:07:55 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux.git/ tags/kgdb-4.21-rc1 for you to fetch changes up to cc0282975b3f887005c380adcf0af95915f0c1bb: kgdb/treewide: constify struct kgdb_arch arch_kgdb_ops (2018-12-30 08:33:06 +0000) ---------------------------------------------------------------- kgdb patches for 4.20-rc1 Mostly clean ups although whilst Doug's was chasing down a odd lockdep warning he also did some work to improved debugger resilience when some CPUs fail to respond to the round up request. The main changes are: * Fixing a lockdep warning on architectures that cannot use an NMI for the round up plus related changes to make CPU round up and all CPU backtrace more resilient. * Constify the arch ops tables * A couple of other small clean ups Two of the three patchsets here include changes that spill over into arch/. Changes in the arch space are relatively narrow in scope (and directly related to kgdb). Didn't get comprehensive acks but all impacted maintainers were Cc:ed in good time.
