Hi Linus,

I'm sending an early pull request for 5.3 as I'll be on holiday for the
next two weeks. The PTRACE_SYSEMU patches touch powerpc and x86 lightly
(the acks are in place). There are a few conflicts but nothing
complicated, the resolution is as per linux-next. If anything goes
wrong, Will is around during the merging window.

Thanks.

The following changes since commit f2c7c76c5d0a443053e94adb9f0918fa2fb85c3a:

  Merge branch 'for-next/perf' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux (2019-07-01 15:53:35 +0100)

----------------------------------------------------------------
arm64 updates for 5.3:

- arm64 support for syscall emulation via PTRACE_SYSEMU{,_SINGLESTEP}

- Wire up VM_FLUSH_RESET_PERMS for arm64, allowing the core code to
  manage the permissions of executable vmalloc regions more strictly

- Slight performance improvement by keeping softirqs enabled while
  touching the FPSIMD/SVE state (kernel_neon_begin/end)

- Expose a couple of ARMv8.5 features to user (HWCAP): CondM (new XAFLAG
  and AXFLAG instructions for floating point comparison flags
  manipulation) and FRINT (rounding floating point numbers to integers)

- Re-instate ARM64_PSEUDO_NMI support which was previously marked as
  BROKEN due to some bugs (now fixed)

- Improve parking of stopped CPUs and implement an arm64-specific
  panic_smp_self_stop() to avoid warning on not being able to stop
  secondary CPUs during panic

- perf: enable the ARM Statistical Profiling Extensions (SPE) on ACPI
  platforms

- perf: DDR performance monitor support for iMX8QXP

- cache_line_size() can now be set from DT or ACPI/PPTT if provided to
  cope with a system cache info not exposed via the CPUID registers

- Avoid warning on hardware cache line size greater than
  ARCH_DMA_MINALIGN if the system is fully coherent

- arm64 do_page_fault() and hugetlb cleanups

- Refactor set_pte_at() to avoid redundant READ_ONCE(*ptep)

- Ignore ACPI 5.1 FADTs reported as 5.0 (infer from the 'arm_boot_flags'
  introduced in 5.1)

- CONFIG_RANDOMIZE_BASE now enabled in defconfig

- Allow the selection of ARM64_MODULE_PLTS, currently only done via
  RANDOMIZE_BASE (and an erratum workaround), allowing modules to spill
  over into the vmalloc area

- Make ZONE_DMA32 configurable
