CVE-2026-98475

s390/cmf: Fix virtual vs physical address confusion

In the Linux kernel, the following vulnerability has been resolved:

s390/cmf: Fix virtual vs physical address confusion

The measurement block address is an absolute address. Define the
associated schib_config and schib fields as dma64_t to enable automatic
detection of incorrect assignments. Also add the missing virt_to_dma64()
translation.

Without this fix, a wrong address will be used by firmware when storing
extended format channel measurement data on kernels built with
CONFIG_RANDOMIZE_IDENTITY_BASE=y.
