#1655266 — [PATCH 3.16 012/212] MIPS: Netlogic: Fix assembler warning from smpboot.S

3.16.44-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Paul Burton <paul.burton@imgtec.com>

commit a8b3b0c94ac282628f0668d1366239a3fa72dc9d upstream.

The netlogic platform can be built for either MIPS32 or MIPS64, and when
built for MIPS32 (as by nlm_xlr_defconfig) the use of the dla
pseudo-instruction leads to warnings such as the following from recent
versions of the GNU assembler:

  arch/mips/netlogic/common/smpboot.S: Assembler messages:
  arch/mips/netlogic/common/smpboot.S:62: Warning: dla used to load 32-bit register; recommend using la instead
  arch/mips/netlogic/common/smpboot.S:63: Warning: dla used to load 32-bit register; recommend using la instead

Avoid these warnings by using the PTR_LA macro to make use of the
appropriate la or dla pseudo-instruction for the build.
