linux-user: Clean up target_signal.h header guards These headers all use TARGET_SIGNAL_H as header guard symbol. Reuse of the same guard symbol in multiple headers is okay as long as they cannot be included together. Since we can avoid guard symbol reuse easily, do so: use guard symbol $target_TARGET_SIGNAL_H for linux-user/$target/target_signal.h.

unicore32: convert get_sp_from_cpustate from macro to inline 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 *)cpu_env)); ^ linux-user/syscall.c:8299:39: error: request for member ‘regs’ in something not a structure or union Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
