CVE: NA

-------------------------------------------------------------------------

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 ad6b9c9d ("ARM: 6671/1: LPAE:
use phys_addr_t instead of unsigned long in outercache functions") has
already modified the outercache functions. But the parameters of the
outercache hooks are not changed. This patch use phys_addr_t instead of
unsigned long in outercache hooks: inv_range, clean_range, flush_range.

To ensure the outercache that does not support LPAE works properly, do
cast phys_addr_t to unsigned long by adding a group of temporary
variables. For example:
-static void l2c220_inv_range(unsigned long start, unsigned long end)
+static void l2c220_inv_range(phys_addr_t pa_start, phys_addr_t pa_end)
 {
+	unsigned long start = pa_start;
+	unsigned long end = pa_end;

Note that the outercache functions have been doing this cast before this
patch. So now, the cast is just moved into the outercache hook functions.

No functional change.
