X-Git-Tag: v2.6.27-rc1~1106^2~249^6

x86 ptrace: fix PTRACE_GETFPXREGS error

ptrace has always returned only -EIO for all failures to access
registers.  The user_regset calls are allowed to return a more
meaningful variety of errors.  The REGSET_XFP calls use -ENODEV
for !cpu_has_fxsr hardware.  Make ptrace return the traditional
-EIO instead of the error code from the user_regset call.
