Dave Hansen e7126cf5f1 x86/mpx: Trace #BR exceptions ... This is the first in a series of MPX tracing patches. I've found these extremely useful in the process of debugging applications and the kernel code itself. This exception hooks in to the bounds (#BR) exception very early and allows capturing the key registers which would influence how the exception is handled. Note that bndcfgu/bndstatus are technically still 64-bit registers even in 32-bit mode.
