As per virtio spec the fields cols and rows are specified as little

In order to successfully execute ENCLS[EUPDATESVN], EPC must be empty.
SGX already has a variable sgx_nr_free_pages that tracks free
EPC pages. Add a new variable, sgx_nr_total_pages, that will keep
track of total number of EPC pages. It will be used in subsequent
patch to change the sgx_nr_free_pa

Device capacity intended for use as system ram should be aligned to the
architecture-defined memory block size or that capacity will be silently
truncated and capacity stranded.
As hotplug dax memory becomes more prevelant, the memory block size

Hi all, now that the printf and scanf series have been taken via kees'

As I understand it, the primary objections to moving bitmap to KUnit were:

- Source churn.
- Extra dependencies for ben

Add a sysctl test that uses the new u8 test ctl files in a created by
the sysctl test module. Check that the u8 proc file that is valid is
created and that there are two messages in dmesg for the files that were
out of range.
