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 Signed-off-by: Dave Hansen <dave.hansen@linux.intel.com> Acked-by: Andy Lutomirski <luto@kernel.org> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Gerst <brgerst@gmail.com> Cc: Dave Hansen <dave@sr71.net> Cc: Denys Vlasenko <dvlasenk@redhat.com> Cc: H.
