Hi; I'm afraid this fails to build on my 32-bit
ARM host:

  CC    aarch64-linux-user/linux-user/syscall.o
/root/qemu/linux-user/syscall.c: In function ‘do_syscall’:
/root/qemu/linux-user/syscall.c:5462:24: error: ‘p’ may be used
uninitialized in this function [-Werror=uninitialized]
cc1: all warnings being treated as errors

Looks like we call fh = lock_user(...) but then use
the wrong variable in the unlock_user() call.

(No idea why this only fails on this machine and
not on x86-64...)

thanks
