("[PATCH v2 00/36] linux-user: Signal trampolines and vdsos")
Changes for v3:
* Drop vdsos, reinstate setup_sigtramp for all targets.
* Incorporate nios2 kuser page emulation, which contains
the sigtramp for that target.
Changes for v2:
* Add vdsos for aarch64, arm, i386, riscv.
* Drop setup_sigtramp for any target with a vdso.
* Drop arm v1 signal support.
* Simplify ppc encode_trampoline.
