v2 --> v3:
Add Hisilicon L3 cache controller driver and its document. That's: patch 2-3.
v1 --> v2:
Discard the middle-tier functions and do silent narrowing cast in the outcache
hook functions. 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;
v1:
Do cast phys_addr_t to unsigned long by adding a middle-tier function.
For example:
-static void l2c220_inv_range(unsigned long start, unsigned long end)
+static void __l2c220_inv_range(unsigned long start, unsigned long end)
{
...
}
+static void l2c220_inv_range(phys_addr_t start, phys_addr_t end)
+{
+ __l2c220_inv_range(start, end);
+}
