CVE-2024-50102 x86: fix user address masking non-canonical speculation issue

In the Linux kernel, the following vulnerability has been resolved: x86: fix user address masking non-canonical speculation issue It turns out that AMD has a "Meltdown Litetm" issue with non-canonical accesses in kernel space. And so using just the high bit to decide whether an access is in user...
