Most x86 two operand instructions allow the destination to be a memory operand, but IMUL (for example) requires that the destination be a register. Change ____emulate_2op() to take a register for both source and destination so we can invoke IMUL. Signed-off-by: -

We'll need it later so we can use a register for the destination. Signed-off-by: -

The code for initializing the emulation context is duplicated at two locations (emulate_instruction() and kvm_task_switch()). Separate it in a separate function and call it from there. Signed-off-by:

The patch adds a new member get_idt() to x86_emulate_ops. It also adds a function to get the idt in order to be used by the emulator. This is needed for real mode interrupt injection and the emulation of int instructions. Signed-off-by:

When using a relocatable kernel we need to make sure that the trampline code and the interrupt handlers are both copied to low memory. The only way to do this reliably is to put them in the copied section. This patch should make relocated kernels work with KVM. KVM-Stable-Tag Signed-off-by:

On Book3S KVM we directly expose some asm pointers to C code as variables. These need to be relocated and thus break on relocatable kernels. To make sure we can at least build, let's mark them as long instead of u32 where 64bit relocations don't work. This fixes the following build error: WARNING: 2 bad relocations^M > c000000000008590 R_PPC64_ADDR32 .text+0x4000000000008460^M > c000000000008594 R_PPC64_ADDR32 .text+0x4000000000008598^M Please keep in mind that actually using KVM on a relocated kernel might still break. This only fixes the compile problem. Reported-by:

Book3S_32 requires MSR_DR to be disabled during load_up_xxx while on Book3S_64 it's supposed to be enabled. I misread the code and disabled it in both cases, potentially breaking the PS3 which has a really small RMA. This patch makes KVM work on the PS3 again. Signed-off-by:
