Jan Beulich 24e35800cd x86: Don't leak 64-bit kernel register values to 32-bit processes
While 32-bit processes can't directly access R8...R15, they can
gain access to these registers by temporarily switching themselves
into 64-bit mode.

Therefore, registers not preserved anyway by called C functions
(i.e. R8...R11) must be cleared prior to returning to user mode.
