Revision 1c48a177351ba8cbf6871f035496fce0e11d8fa3 authored by James Hogan on 20 May 2016, 22:28:38 UTC, committed by Ralf Baechle on 28 May 2016, 10:35:10 UTC
Toolchains may be used which support microMIPS but not VZ instructions
(i.e. binutis 2.22 & 2.23), so extend the explicitly encoded versions of
the guest COP0 register & guest TLB access macros to support microMIPS
encodings too, using the new macros.
This prevents non-microMIPS instructions being executed in microMIPS
mode during CPU probe on cores supporting VZ (e.g. M5150), which cause
reserved instruction exceptions early during boot.
Fixes: bad50d79255a ("MIPS: Fix VZ probe gas errors with binutils <2.24")
