Subject: [PATCH 00/13] deprecate pcommit
Platforms supporting NVDIMMs are now required to provide persistence
guarantees once pmem stores are accepted by the memory subsystem. This
is usually achieved by a platform-level feature known as ADR
(Asynchronous DRAM Refresh) that flushes any memory subsystem write
pending queues on power loss/shutdown.
The 'pcommit' instruction (which has not shipped on any product) is no
longer needed and is deprecated.

Dan Williams (13):
driver core, libnvdimm: disable manual unbind of dimms while region active
nfit: always associate flush hints
libnvdimm: introduce nvdimm_flush()
libnvdimm, nfit: move flush hint mapping to dimm driver
tools/testing/nvdimm: simulate multiple flush hints per-dimm
libnvdimm: cycle flush hints per-cpu
libnvdimm, pmem: use REQ_FUA, REQ_FLUSH for nvdimm_flush()
fs/dax: remove wmb_pmem()
libnvdimm, pmem: use nvdimm_flush() for namespace I/O writes
pmem: kill wmb_pmem()
Revert "KVM: x86: add pcommit support"
x86/insn: remove pcommit
pmem: kill __pmem address space
