arm64: KVM: Allow the main HYP code to use the init hyp stub implementation

We now have a full hyp-stub implementation in the KVM init code,
but the main KVM code only supports HVC_GET_VECTORS, which is not
enough.

Instead of reinventing the wheel, let's reuse the init implementation
by branching to the idmap page when called with a hyp-stub hypercall.

As we're about to get rid of the latter, let's move the save/restore
code to the do_el2_call macro, unifying both code paths.

Pull arm64 updates from Catalin Marinas:

- 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)

arm64: Support systems without FP/ASIMD

The arm64 kernel assumes that FP/ASIMD units are always present
and accesses the FP/ASIMD specific registers unconditionally. This
could cause problems when they are absent. This patch adds the
support for kernel handling systems without FP/ASIMD by skipping the
register access within the kernel. For kvm, we trap the accesses
to FP/ASIMD and inject an undefined instruction exception to the VM.

The callers of the exported kernel_neon_begin_partial() should
make sure that the FP/ASIMD is supported.
