Thomas Gleixner 6f41c34d69 x86/mce: Make machine check speculation protected ... The machine check idtentry uses an indirect branch directly from the low level code. This evades the speculation protection. Replace it by a direct call into C code and issue the indirect call there so the compiler can apply the proper speculation protection.
