The __switch_to function in arch/x86/kernel/process_64.c in the Linux
kernel through 3.18.1 does not ensure that Thread Local Storage (TLS)
descriptors are loaded before proceeding with other steps, which makes it
easier for local users to bypass the ASLR protection mechanism via a
crafted application that reads a TLS base address.
