Ian Campbell f020e29051 privcmd: MMAPBATCH: Fix error handling/reporting ... On error IOCTL_PRIVCMD_MMAPBATCH is expected to set the top nibble of the effected MFN and return 0. Currently it leaves the MFN unmodified and returns the number of failures. Therefore: - reimplement remap_domain_mfn_range() using direct HYPERVISOR_mmu_update() calls and small batches. The xen_set_domain_pte() interface does not report errors and since some failures are expected/normal using the multicall infrastructure is too noisy. - return 0 as expected - writeback the updated MFN list to mmapbatch->arr not over mmapbatch, smashing the caller's stack. - remap_domain_mfn_range can be static. With this change I am able to start an HVM domain.
