[patch 3/3] x86, ptrace: remove set_stopped_child_used_math() in [x]fpregs_set

[Suresh Siddha <suresh.b.siddha@intel.com>]

[-- Attachment #1: fix_fpregset_set_stopped_child_used_math.patch --]
[-- Type: text/plain, Size: 945 bytes --]

init_fpu() already ensures that the used_math() is set for the stopped child.
Remove the redundant set_stopped_child_used_math() in [x]fpregs_set()
