Revision be8cfc4af15cf611dfeb66a1fb5df43d5f1e280a authored by Mark Salter on 25 September 2012, 00:17:38 UTC, committed by Linus Torvalds on 25 September 2012, 15:59:21 UTC
Commit 1ad75b9e1628 ("c/r: prctl: add minimal address test to PR_SET_MM") added some address checking to prctl_set_mm() used by checkpoint-restore. This causes a build error for no-MMU systems: kernel/sys.c: In function 'prctl_set_mm': kernel/sys.c:1868:34: error: 'mmap_min_addr' undeclared (first use in this function) The test for mmap_min_addr doesn't make a lot of sense for no-MMU code as noted in commit 6e1415467614 ("NOMMU: Optimise away the {dac_,}mmap_min_addr tests"). This patch defines mmap_min_addr as 0UL in the no-MMU case so that the compiler will optimize away tests for "addr < mmap_min_addr".
