函数名称：These CPUs all support 44bits physical address space internally in the* cache but CPUID can report a smaller number of physical address bits.* The L1TF mitigation uses the top most address bit for the inversion of* non present PTEs

函数原型：static void override_cache_bits(struct cpuinfo_x86 *c)

返回类型：void

参数：

类型参数名称
struct cpuinfo_x86 *c
