From 5a0b1d78bfc5ca4079ea03abb0ecc0d61d676e41 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Sat, 4 Oct 2014 03:50:33 +0400 Subject: xtensa: nommu: clean up memory map dump noMMU configuration doesn't use special area for vmalloc allocations, don't print it in the memory map. PAGE_OFFSET is fixed to 0 in noMMU, use min_low_pfn and max_low_pfn for lowmem range display. Make all XCHAL_KSEG_* constants unsigned long for consistency with other addresses.
