Subject: MIPS: kernel: cps-vec: Replace 'la' macro with PTR_LA
From: Markos Chandras <markos.chandras@xxxxxxxxxx>
commit 81a02e34ded906357deac7003fbb0d36b6cc503f upstream.
The PTR_LA macro will pick the correct "la" or "dla" macro to
load an address to a register. This gets rids of the following
warnings (and others) when building a 64-bit CPS kernel:
arch/mips/kernel/cps-vec.S:63: Warning: la used to load 64-bit address
arch/mips/kernel/cps-vec.S:159: Warning: la used to load 64-bit address
arch/mips/kernel/cps-vec.S:220: Warning: la used to load 64-bit address
arch/mips/kernel/cps-vec.S:240: Warning: la used to load 64-bit address
[...]
