The spec only requires the posted interrupt descriptor address to be
64-bytes aligned (i.e. bits[0:5] == 0). Using page_address_valid also
forces the address to be page aligned.
Only validate that the address does not cross the maximum physical address
without enforcing a page alignment.

I'm on the quest to figure out why perf regularly fails to unwind (some)

Use kvm_vcpu_map when mapping the L1 MSR bitmap since using
kvm_vcpu_gpa_to_page() and kmap() will only work for guest memory that has

In c4iw_flush_hw_cq, the next CQE is acquired through t4_next_hw_cqe(). In
t4_next_hw_cqe(), the CQE, i.e., 'cq->queue[cq->cidx]', is checked to see
whether it is valid through t4_valid_cqe(). If it is valid, the address of

The spec only requires the posted interrupt descriptor address to be
64-bytes aligned (i.e. bits[0:5] == 0). Using page_address_valid also
forces the address to be page aligned.
Only validate that the address does not cross the maximum physical address
without enforcing a page alignment.

We are one image studio who is able to process 300+ photos a day.
If you need any image editing, please let us know. We can do it for you
such as:
Image cut out for photos and clipping path, masking for your photos,
They are mostly used for ecommerce photos, jewelry photos retouching,
beauty

In tb_ring_poll(), the flag of the frame, i.e.,
'ring->descriptors[ring->tail].flags', is checked to see whether the frame
is completed. If yes, the frame including the flag will be read from the
ring and returned to the caller. The problem here is that the flag is
actually in a DMA region, which
