This patch provides the MMIO load/store emulation for instructions of 'double & vector unsigned char & vector signed char & vector unsigned short & vector signed short & vector unsigned int & vector signed int & vector double '. The instructions that this adds emulation for are: - ldx, ldux, lwax, - lfs, lfsx, lfsu, lfsux, lfd, lfdx, lfdu, lfdux, - stfs, stfsx, stfsu, stfsux, stfd, stfdx, stfdu, stfdux, stfiwx, - lxsdx, lxsspx, lxsiwax, lxsiwzx, lxvd2x, lxvw4x, lxvdsx, - stxsdx, stxsspx, stxsiwx, stxvd2x, stxvw4x [paulus@ozlabs.org - some cleanups, fixes and rework, make it compile for Book E, fix build when PR KVM is built in] Signed-off-by: Bin Lu <lblulb@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@ozlabs.org>
