Depending on the target architecture and configuration, both phys_addr_t

drivers/scsi/qla2xxx/qla_iocb.c:1140:46: error: format '%llx' expects argument of type 'long long unsigned int', but argument 6 has type 'dma_addr_t' {aka 'unsigned int'} [-Werror=format=]

"%s: sg[%x] (phys=%llx sglen=%x) ldma_sg_len: %x dif_bundl_len: %x ldma_needed: %x\n",
~~~^
There are special %pad and %pap format strings in Linux that we could use
here, but since the driver already does 64-bit arithmetic on the values,
using a plain 'u64' seems more consistent here.
Note: A possible related issue may be that the driver possibly checks the
wrong kind of overflow: when an IOMMU is in use, buffers that cross a
32-bit boundary in physical addresses would still be mapped into dma
addresses within the low 4GB space, so I suspect that we actually want to
check sg_dma_address() instead of sg_phys() here.

Two fairly small fixes: the qla one is a panic inducing use after free
and the entropy fix may seem minor but it has had huge userspace
impact thanks to an unrelated change in openssl that causes sshd to
refuse logins until it has enough entropy for the session keys, which
causes tens of minutes delay before the affected systems allow logins
after reboot.
