MIPS: DSP: Fix DSP mask for registers.
The DSP bit mask for the RDDSP and WRDSP instructions was wrong. [ralf@linux-mips.org: The mask field of the RDDSP and WRDSP instructions is 10 bits long. DSP_MASK had all these fields which according to the architecture specification may result in UNPREDICTABLE operation.] Signed-off-by: Steven J. Hill <sjhill@mips.com> Cc: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/4683/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
