- struct thread_info moved off-stack (also touching
include/linux/thread_info.h and include/linux/restart_block.h)
- cpus_have_cap() reworked to avoid __builtin_constant_p() for static
key use (also touching drivers/irqchip/irq-gic-v3.c)
- Uprobes support (currently only for native 64-bit tasks)
- Emulation of kernel Privileged Access Never (PAN) using TTBR0_EL1
switching to a reserved page table
- CPU capacity information passing via DT or sysfs (used by the
scheduler)
- Support for systems without FP/SIMD (IOW, kernel avoids touching these
registers; there is no soft-float ABI, nor kernel emulation for
AArch64 FP/SIMD)
- Handling of hardware watchpoint with unaligned addresses, varied
lengths and offsets from base
- Use of the page table contiguous hint for kernel mappings
- Hugetlb fixes for sizes involving the contiguous hint
- Remove unnecessary I-cache invalidation in flush_cache_range()
- CNTHCTL_EL2 access fix for CPUs with VHE support (ARMv8.1)
- Boot-time checks for writable+executable kernel mappings
- Simplify asm/opcodes.h and avoid including the 32-bit ARM counterpart
and make the arm64 kernel headers self-consistent (Xen headers patch
merged separately)
- Workaround for broken .inst support in certain binutils versions
