[Qemu-devel] [PATCH] linux-user: remove unnecessary local from __get_user(), __put_user()

[Peter Maydell]

Remove an unnecessary local variable from the __get_user() and
__put_user() macros. This avoids confusing compilation failures
if the name of the local variable ('size') happens to be the
same as the variable the macro user is trying to read/write.
