Dave Hansen 8709ed4d4b x86/cpu: Fix duplicated X86_BUG(9) macro
cpufeatures.h currently defines X86_BUG(9) twice on 32-bit:

	#define X86_BUG_NULL_SEG        X86_BUG(9) /* Nulling a selector preserves the base */
	...
	#ifdef CONFIG_X86_32
	#define X86_BUG_ESPFIX          X86_BUG(9) /* "" IRET to 16-bit SS corrupts ESP/RSP high bits */
	#endif

I think what happened was that this added the X86_BUG_ESPFIX, but
in an #ifdef below most of the bugs:

	58a5aac533 x86/entry/32: Introduce and use X86_BUG_ESPFIX instead of paravirt_enabled

Then this came along and added X86_BUG_NULL_SEG, but collided
with the earlier one that did the bug below the main block
defining all the X86_BUG()s.

	7a5d670487 x86/cpu: Probe the behavior of nulling out a segment at boot time
