Subject: [PATCH v2 01/10] ppc: Drop PPC_EMULATE_32BITS_HYPV stub
Date: Tue,  7 Jan 2020 15:48:18 +1100	[thread overview]
Message-ID: <20200107044827.471355-2-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20200107044827.471355-1-david@gibson.dropbear.id.au>

The only effect of the PPC_EMULATE_32BITS_HYPV define is to change how
MSR_HVB is defined.  This appears to be something to handle hypervisor mode
for 32-bit CPUs, but there's really no other code to handle this.  The
MSR_THV bit, which it uses is implemented for no cpus we model.

It's unlikely anyone is going to implement this any time soon, so just drop
it.
