Linus Torvalds dfd437a257 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
