Subject: [PATCH 0/5] Enable pt_regs based syscalls for x86-32 native

This patch series cleans up the x86 syscall wrapper code and converts
the 32-bit native kernel over to pt_regs based syscalls.

Brian Gerst (5):
  x86: Refactor syscall_wrapper.h
  x86: Move 32-bit compat syscalls to common location
  x86-32: Enable syscall wrappers
  x86-64: Use syscall wrappers for x32_rt_sigreturn
  x86: Drop asmlinkage from syscalls
