Linus Torvalds 72674d4800 A series of fixes for x86:
- Reset MXCSR in kernel_fpu_begin() to prevent using a stale user space
    value.
 
  - Prevent writing MSR_TEST_CTRL on CPUs which are not explicitly
    whitelisted for split lock detection. Some CPUs which do not support
    it crash even when the MSR is written to 0 which is the default value.
 
  - Fix the XEN PV fallout of the entry code rework
 
  - Fix the 32bit fallout of the entry code rework
 
  - Add more selftests to ensure that these entry problems don't come back.
 
  - Disable 16 bit segments on XEN PV. It's not supported because XEN PV
    does not implement ESPFIX64
