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.
