[PATCH 4.17 186/336] EDAC, altera: Fix ARM64 build warning

[Greg Kroah-Hartman]

4.17-stable review patch.  If anyone has any objections, please let me know.

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

From: Thor Thayer <thor.thayer@xxxxxxxxxxxxxxx>

[ Upstream commit 9ef20753e044f7468c4113e5aecd785419b0b3cc ]

The kbuild test robot reported the following warning:

  drivers/edac/altera_edac.c: In function 'ocram_free_mem':
  drivers/edac/altera_edac.c:1410:42: warning: cast from pointer to integer
	of different size [-Wpointer-to-int-cast]
    gen_pool_free((struct gen_pool *)other, (u32)p, size);
                                             ^

After adding support for ARM64 architectures, the unsigned long
parameter is 64 bits and causes a build warning on 64-bit configs. Fix
by casting to the correct size (unsigned long) instead of u32.
