Subject: [PATCH] powerpc: ARCH_PFN_OFFSET should be unsigned long
Date: Thu, 24 Mar 2011 16:51:19 -0500 [thread overview]
Message-ID: <20110324215119.GB9632@schlenkerla.am.freescale.net> (raw)
pfns are unsigned long, but MEMORY_START is phys_addr_t. This leads
to page_to_pfn() returning phys_addr_t, and thus type mismatches in a few
print statements.
