Borislav Petkov 58fb3c3589 x86/mitigations: Clear CPU buffers on the SYSCALL fast path 
The fast SYSCALL exit path returns with SYSRET to userspace after
verifying that there's no pending work. MDS mitigation mandates that CPU
buffers must be cleared on transition from kernel to userspace so do
that here too.
