A recent bug fix to the MSIx handling in vfio added references
to functions that may not be defined if MSI is disabled in the kernel,
resulting in this link error:
drivers/built-in.o: In function `vfio_msi_set_vector_signal':
:(.text+0x450808): undefined reference to `get_cached_msi_msg'

As far as I can see, the only path leading to the ioctl is
vhost_scsi_set

Does it make sense to split the thing in two? One where you apply
_unlocked and then one where you apply _fast?

Just do not pass it, which is roughly the same behavior that KVM had
until 3.17. Passing a non-existing flag could have unanticipated
effects.

Passing end=start+1 is the easiest way to call the new callback from
the old API. That is how kvm_handle_hva is implemented on top of
kvm_handle_hva_range. So, now that kvm_age_hva calls kvm_handle_hva_range
instead of kvm_handle_hva, you can apply the same trick to the caller
of kvm_age_hva.
Si
zero_pfn is not exported before 3.17.

When read access is performed using a readable code segment, the "conforming"
and "non-conforming" checks should not be done. As a result, read using
non-conforming readable code segment fails.
This is according to Intel SDM 5.6.1 ("Accessing Data in Code Segments").
One exception is the case of
This patch series adds support for ARMv8 dirty page logging. It applies on top
of ARMv7 patch series. Similar ARMv8 to dirty page log read is moved to generic
layer and tlb flush has architecture specific flush.
Testing:
- ARMv8 - Tested on Foundation Model.
- ARMv7 - retested on Exynos 5
This patch introduces header updates for ARMv8 dirty page logging.
