- * Instantiations of the elf_fpregset_t type contain, in most
- * architectures, the floating point (FPU) register set.
- * For Xtensa, this type is extended to contain all custom state,
- * ie. coprocessor and "extra" (non-coprocessor) state (including,
- * for example, TIE-defined states and register files; as well
- * as other optional processor state).
- * This includes FPU state if a floating-point coprocessor happens
- * to have been configured within the Xtensa processor.
- *
- * TOTAL_FPREGS_SIZE is the required size (without rounding)
- * of elf_fpregset_t.  It provides space for the following:
- *
- *  a)	32-bit mask of active coprocessors for this task (similar
- *	to CPENABLE in single-threaded Xtensa processor systems)
- *
- *  b)	table describing the layout of custom states (ie. of
- *      individual registers, etc) within the save areas
- *
- *  c)  save areas for each coprocessor and for non-coprocessor
- *      ("extra") state
- *
- * Note that save areas may require up to 16-byte alignment when
- * accessed by save/restore sequences.  We do not need to ensure
- * such alignment in an elf_fpregset_t structure because custom
- * state is not directly loaded/stored into it; rather, save area
- * contents are copied to elf_fpregset_t from the active save areas
- * (see 'struct task_struct' definition in processor.h for that)
- * using memcpy().  But we do allow space for such alignment,
- * to allow optimizations of layout and copying.
