Subject: [PATCH v2 0/1] ARM: LPAE: use phys_addr_t instead of unsigned long in outercache hooks
Date: Wed, 30 Dec 2020 16:28:04 +0800	[thread overview]
Message-ID: <20201230082805.1428-1-thunder.leizhen@huawei.com> (raw)

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);
+}
