    x86: user_regset_view table fix for ia32 on 64-bit
    The user_regset_view table for the 32-bit regsets on the 64-bit build had
    the wrong sizes for the FP regsets.  This bug had no user-visible effect
    (just on kernel modules using the user_regset interfaces and the like).
    But the fix is trivial and risk-free.

Roland, could you comment on whether or not this patch is needed in RHEL5?


Comment 3 Roland McGrath 2008-07-21 16:14:28 EDT
RHEL5 never had this bug, it was introduced during the refactoring for upstream.
