From: Stephen Rothwell on 28 Jul 2010 00:10 Hi all, After merging the final tree, next-20100726 build (i386 allmodconfig) failed like this: In file included from arch/x86/include/asm/uaccess.h:571, from include/linux/uaccess.h:5, from include/linux/highmem.h:6, from include/linux/pagemap.h:10, from kernel/trace/trace.c:24: arch/x86/include/asm/uaccess_32.h: In function 'copy_from_user': arch/x86/include/asm/uaccess_32.h:212: error: call to 'copy_from_user_overflow' declared with attribute error: copy_from_user() buffer size is not provably correct Probably caused by commit e5738a3d75254c6d135ccad925e513ddb860967e ("ftrace,kdb: Extend kdb to be able to dump the ftrace buffer") from the kgdb tree which turned off optimization (and therefore probably inlining) for kernel/trace/trace.c ... -- Cheers, Stephen Rothwell sfr(a)canb.auug.org.au http://www.canb.auug.org.au/~sfr/ |
