Series fully reviewed.
- Patches 1-11 fix migration on HVF
- Patches 12-14 remove a signal race with WFI
- Patches 15-18 correct guest timer frequency
Since v5:
- Rebased on top of 3bee93b9abf ("Fix i386 HVF compilation failures")
Since v4:
- Rename gva -> gpa in hvf_set_phys_mem (Akihiko)
- Dropped missing VTimer synchronization patches for 10.2
Since v3:
- Call qemu_real_host_page_mask/size once (rth)
Since v2:
- Improve host page size/mask uses (rth)
- Remove cpu_test_interrupt in hvf_wfi (rth)
Since v1:
- Addressed Mads & Richard comments
- Fixed migration by reworking memory listeners
(unfortunately the current broken code has been
used as base for WHPX)
- Sync CNTV_CTL/CVAL_EL0
- Remove WFI racy signal implementation
- Simplify PSCI Suspend (I expect the same can be
done for the other hvf_psci_cpu_off() calls).
- Emulate more missing registers (PMU & Monitor Dbg)
>From v1:
- Fix a pair of memory leak
- Check a pair of return values
- Mention calls which must be run on vCPU thread
- Force MIDR
- Use hv_vcpu_config_create/hv_vcpu_config_get_feature_reg
when not running on vCPU thread
- Factor hvf_handle_vmexit() / hvf_handle_exception(() out
- Call hv_vcpu_run() in loop
- Guard hv_vcpu_run() between cpu_exec_start/end()
- Restrict ARM specific in AccelCPUState
