Subject: [GIT PULL] arm64 patches for 4.18
Hi Linus,
Please pull the arm64 updates for 4.18 below. Apart from the core arm64
and perf changes, the Spectre v4 mitigation touches the arm KVM code and
the ACPI PPTT support touches drivers/ (acpi and cacheinfo). I should
have the maintainers' acks in place.
Thanks.
The following changes since commit 75bc37fefc4471e718ba8e651aa74673d4e0a9eb:
Linux 4.17-rc4 (2018-05-06 16:57:38 -1000)
are available in the git repository at:

arm64: Fix syscall restarting around signal suppressed by tracer (2018-06-08 13:21:39 +0100)
----------------------------------------------------------------
arm64 updates for 4.18:
- Spectre v4 mitigation (Speculative Store Bypass Disable) support for
arm64 using SMC firmware call to set a hardware chicken bit
- ACPI PPTT (Processor Properties Topology Table) parsing support and
enable the feature for arm64
- Report signal frame size to user via auxv (AT_MINSIGSTKSZ). The
primary motivation is Scalable Vector Extensions which requires more
space on the signal frame than the currently defined MINSIGSTKSZ
- ARM perf patches: allow building arm-cci as module, demote dev_warn()
to dev_dbg() in arm-ccn event_init(), miscellaneous cleanups
- cmpwait() WFE optimisation to avoid some spurious wakeups
- L1_CACHE_BYTES reverted back to 64 (for performance reasons that have
to do with some network allocations) while keeping ARCH_DMA_MINALIGN
to 128. cache_line_size() returns the actual hardware Cache Writeback
Granule
- Turn LSE atomics on by default in Kconfig
- Kernel fault reporting tidying
- Some #include and miscellaneous cleanups
----------------------------------------------------------------
