Subject: target/ppc: Merge cpu_ppc_set_vhyp() with cpu_ppc_set_papr()
X-Git-Tag: v2.9.0-rc0~43^2~41
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b7b0b1f13a9d0b77b3dcb7696de420c2e805ca25;p=thirdparty%2Fqemu.git

target/ppc: Merge cpu_ppc_set_vhyp() with cpu_ppc_set_papr()

cpu_ppc_set_papr() sets up various aspects of CPU state for use with PAPR
paravirtualized guests.  However, it doesn't set the virtual hypervisor,
so callers must also call cpu_ppc_set_vhyp() so that PAPR hypercalls are
handled properly.  This is a bit silly, so fold setting the virtual
hypervisor into cpu_ppc_set_papr().
