Subject: [PATCH v7 24/32] KVM: PPC: Book3S HV: Remove virt mode checks from real mode handlers
Date: Fri, 28 May 2021 19:07:44 +1000 [thread overview]
Message-ID: <20210528090752.3542186-25-npiggin@gmail.com> (raw)
In-Reply-To: <20210528090752.3542186-1-npiggin@gmail.com>
Now that the P7/8 path no longer supports radix, real-mode handlers
do not need to deal with being called in virt mode.
This change effectively reverts commit acde25726bc6 ("KVM: PPC: Book3S
HV: Add radix checks in real-mode hypercall handlers").
It removes a few more real-mode tests in rm hcall handlers, which
allows the indirect ops for the xive module to be removed from the
built-in xics rm handlers.
kvmppc_h_random is renamed to kvmppc_rm_h_random to be a bit more
descriptive and consistent with other rm handlers.
