I found that if try to compile twice, the first time has no problem but
the second time (make clean./configuremake) will meet the error.
Yes, 'make clean' was too eager. Fixed.

It's difficult to get anything booting with upstream PowerPC qemu,
mostly because of the unmaintained firmware they use (called Open

Emulating all of the real mode shouldn't be too much of a problem on

take about as much time as the emulation overhead.
For the bootstrap process emulation is good enough, since the process is

Batch pte updates and tlb flushes in lazy MMU mode.
I am slightly uneasy about generic hypercall batching. An alternative
way to do it would be to define a kvm_mmu_op structure (with an embedded
opcode) and have a single hypercall execute a number of these (and not

Mark zapped root pagetables as invalid and ignore such pages during lookup.
This is a problem with the cr3-target feature, where a zapped root table fools
the faulting code into creating a read-only mapping. The result is a lockup
if the instruction can't be emulated.

Applied, thanks.
