From: David Daney <david.daney@xxxxxxxxxx>Hi,
This reverts commit 77f3ee59ee7cfe19e0ee48d9a990c7967fbfcbed.
There are two problems:
1) It breaks OCTEON, which will now crash in early boot with:
Kernel panic - not syncing: No TLB refill handler yet (CPU type: 80)
2) The logic is broken.
The meaning of cpu_has_mips_r2_exec_hazard is that the EHB instruction
is required. The offending patch attempts (and fails) to change the
meaning to be that EHB is part of the ISA.

First of all sorry about the octeon breakage.
However, whilst this patch will fix Octeon it will break R6
Can we please consider another patch that will simply use
cpu_has_mips_r2_r6 instead of cpu_has_mips_r2 so both will work in 4.0?
