Hi Linus, Please pull powerpc updates for 4.15. Apologies this is a bit late, we had some late breaking fixes come in.
A bit of a small release, I suspect in part due to me travelling for KS.
But my backlog of patches to review is smaller than usual, so I think in
part folks just didn't send as much this cycle.
There's two conflicts you'll see. The first in KVM code against a fix
that went through Paul's tree, and the other against one of the timer
changes.
The correct resoultion in the KVM case is:
case KVM_CAP_PPC_HTM:
r = hv_enabled &&
(cur_cpu_spec->cpu_user_features2 & PPC_FEATURE2_HTM_COMP);
And for the timer change:
mod_timer(&topology_timer, jiffies + topology_timer_secs * HZ);
cheers

powerpc/64s: Fix Power9 DD2.0 workarounds by adding DD2.1 feature (2017-11-15
14:25:42 +1100)
----------------------------------------------------------------
powerpc updates for 4.15
Non-highlights:
- Five fixes for the >128T address space handling, both to fix bugs in our
implementation and to bring the semantics exactly into line with x86.
Highlights:
- Support for a new OPAL call on bare metal machines which gives us a true NMI
(ie. is not masked by MSR[EE]=0) for debugging etc.
- Support for Power9 DD2 in the CXL driver.
- Improvements to machine check handling so that uncorrectable errors can be
reported into the generic memory_failure() machinery.
- Some fixes and improvements for VPHN, which is used under PowerVM to notify
the Linux partition of topology changes.
- Plumbing to enable TM (transactional memory) without suspend on some Power9
processors (PPC_FEATURE2_HTM_NO_SUSPEND).
- Support for emulating vector loads form cache-inhibited memory, on some
Power9 revisions.
- Disable the fast-endian switch "syscall" by default (behind a CONFIG), we
believe it has never had any users.
- A major rework of the API drivers use when initiating and waiting for long
running operations performed by OPAL firmware, and changes to the
powernv_flash driver to use the new API.
- Several fixes for the handling of FP/VMX/VSX while processes are using
transactional memory.
- Optimisations of TLB range flushes when using the radix MMU on Power9.
- Improvements to the VAS facility used to access coprocessors on Power9, and
related improvements to the way the NX crypto driver handles requests.
- Implementation of PMEM_API and UACCESS_FLUSHCACHE for 64-bit.
