In the Linux kernel, the following vulnerability has been resolved:net: wwan: t7xx: Split 64bit accesses to fix alignment issuesSome of the registers are aligned on a 32bit boundary, causing
alignment faults on 64bit platforms.Unable to handle kernel paging request at virtual address ffffffc084a1d004

 ---[ end trace 0000000000000000 ]---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.
