phys_to_virt

函数名称：phys_to_virt - map physical address to virtual*@address: address to remap* The returned virtual address is a current CPU mapping for* the memory address given. It is only valid to use this function on* addresses that have a kernel mapping

函数原型：static inline void *phys_to_virt(phys_addr_t address)

返回类型：void

machine_kexec	Do not allocate memory (or fail in any way) in machine_kexec().* We are past the point of no return, committed to rebooting now.
swiotlb_update_mem_attributes	Early SWIOTLB allocation may be too early to allow an architecture to* perform the desired operations. This function allows the architecture to* call SWIOTLB when the operations are possible. It needs to be called* before the SWIOTLB memory is used.
