[Qemu-trivial] [PATCH trivial] unicore32: convert get_sp_from_cpustate f

From: Michael Tokarev
Subject: [Qemu-trivial] [PATCH trivial] unicore32: convert get_sp_from_cpustate from macro to inline
Date: Tue, 29 Dec 2015 12:43:39 +0300

All other architectures define get_sp_from_cpustate as an inline function,
only unicore32 uses a #define.  With this, some usages are impossible, for
example, enabling sigaltstack in linux-user/syscall.c results in

linux-user/syscall.c: In function ‘do_syscall’:
linux-user/syscall.c:8299:39: error: dereferencing ‘void *’ pointer [-Werror]
  get_sp_from_cpustate(arg1, arg2, get_sp_from_cpustate((CPUArchState 
linux-user/syscall.c:8299:39: error: request for member ‘regs’ in something not 
a structure or union
