x86: user_regset user-copy helpers
This defines two new inlines in linux/regset.h, for use in arch_ptrace
implementations and the like. These provide simplified wrappers for using
the user_regset interfaces to copy thread regset data into the caller's
user-space memory. The inlines are trivial, but make the common uses in
places such as ptrace implementation much more concise, easier to read, and
less prone to code-copying errors.
