[PATCH v3 06/27] x86/cea: Export per CPU variable cea_exception_stacks

[Xin Li (Intel)]

The per CPU variable cea_exception_stacks contains per CPU stacks for
NMI, #DB and #DF, which is referenced in KVM to set host FRED RSP[123]
each time a vCPU is loaded onto a CPU, thus it needs to be exported.
