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

net: wwan: t7xx: Split 64bit accesses to fix alignment issues

Some of the registers are aligned on a 32bit boundary, causing alignment faults on 64bit platforms.

The inclusion of io-64-nonatomic-lo-hi.h indicates that all 64bit accesses can be replaced by pairs of nonatomic 32bit access. Fix alignment by forcing all accesses to be 32bit on 64bit platforms.
