    Hi,

    In the i386 kernel (from 2.3.11), CR4 value is saved into the variable
    mmu_cr4_features, which will be restored to CR4 in some case. But the
    variable is not exported.

    In the CR4 register, there is a flag that enables reading performance
    counters using RDPMC instruction in user mode.

    I strongly hope to add "mmu_cr4_features" to exported list to make
    this bit on/of from a kernel module.

    + EXPORT_SYMBOL(mmu_cr4_features);
