[PATCH v2 1/1] ARM: LPAE: use phys_addr_t instead of unsigned long in outercache hooks

2020-12-30 Thread Zhen Lei
The outercache of some Hisilicon SOCs support physical addresses wider than 32-bits. The unsigned long datatype is not sufficient for mapping physical addresses >= 4GB. The commit ad6b9c9d78b9 ("ARM: 6671/1: LPAE: use phys_addr_t instead of unsigned long in outercache functions") has already
