KVM: PPC: e500: Fix bad address type in deliver_tlb_misss()

2014-04-01T23:58:45+00:00

commit 70713fe315ed14cd1bb07d1a7f33e973d136ae3d upstream. Use gva_t instead of unsigned int for eaddr in deliver_tlb_miss(). Signed-off-by: Mihai Caraman Signed-off-by: Alexander Graf [bwh: Backported to 3.2: adjust filename] Signed-off-by: Ben Hutchings

KVM: PPC: Book3S HV: Fix typo in saving DSCR

2013-11-28T14:02:02+00:00

commit cfc860253abd73e1681696c08ea268d33285a2c4 upstream. This fixes a typo in the code that saves the guest DSCR (Data Stream Control Register) into the kvm_vcpu_arch struct on guest exit. The effect of the typo was that the DSCR value was saved in the wrong place, so changes to the DSCR by the guest didn't persist across guest exit and entry, and some host kernel memory got corrupted.

KVM: PPC: Emulate dcbf

2013-02-06T04:33:37+00:00

commit d3286144c92ec876da9e30320afa875699b7e0f1 upstream. Guests can trigger MMIO exits using dcbf. Since we don't emulate cache incoherent MMIO, just do nothing and move on.

KVM: PPC: 44x: fix DCR read/write

2013-01-03T03:32:59+00:00

commit e43a028752fed049e4bd94ef895542f96d79fa74 upstream. When remembering the direction of a DCR transaction, we should write to the same variable that we interpret on later when doing vcpu_run again.

powerpc/kvm: sldi should be sld

2012-07-12T03:32:04+00:00

commit 2f584a146a2965b82fce89b8d2f95dc5cfe468d0 upstream. Since we are taking a registers, this should never have been an sldi. Talking to paulus offline, this is the correct fix. Was introduced by: commit 19ccb76a1938ab364a412253daec64613acbf3df Author: Paul Mackerras Date: Sat Jul 23 17:42:46 2011 +1000 Talking to paulus, this shouldn't be a literal.

KVM: PPC: e500: include linux/export.h

This is required for THIS_MODULE. We recently stopped acquiring it via some other header. Signed-off-by: Scott Wood Signed-off-by: Alexander Graf

KVM: PPC: fix kvmppc_start_thread() for CONFIG_SMP=N

2011-12-26T11:28:02+00:00

Currently kvmppc_start_thread() tries to wake other SMT threads via xics_wake_cpu(). Unfortunately xics_wake_cpu only exists when CONFIG_SMP=Y so when compiling with CONFIG_SMP=N we get: arch/powerpc/kvm/built-in.o: In function `.kvmppc_start_thread': book3s_hv.c:(.text+0xa1e0): undefined reference to `.xics_wake_cpu' The following should be fine since kvmppc_start_thread() shouldn't called to start non-zero threads when SMP=N since threads_per_core=1.

This reverts commit a15bd354f083f20f257db450488db52ac27df439. It exceeded the padding on the SREGS struct, rendering the ABI backwards-incompatible. Conflicts: arch/powerpc/kvm/powerpc.c include/linux/kvm.h Signed-off-by: Avi Kivity
