From: Steven Rostedt <rostedt@xxxxxxxxxxx> Subject: [RFC][PATCH] extable: Make sure all archs define _sdata Date: Thu, 19 May 2011 21:34:58 -0400 > Can I get an Acked-by (or comment) from the following Maintainers: > > alpha > m32r > m68k > mips > parisc > > Ingo has discovered that one of my patches broke the builds of these > architectures. Although he added a quick fix, this patch supplies the > proper fix and touches the affected architectures. Please review and Ack > (or NACK with guidance) this patch. > > -- Steve > > A new utility function is used to determine if a passed in address is > part of core kernel data or not. It may or may not return true for RO > data, but this utility must work for RW data. Thus both _sdata and > _edata must be defined and continuous, without .init sections that may > later be freed and replaced by volatile memory (memory that can be > freed). > > This utility function is used to determine if data is safe from ever > being freed. Thus it should return true for all RW global data that is > not in a module or has been allocated, or false otherwise. > > Signed-off-by: Steven Rostedt <rostedt@xxxxxxxxxxx> > ---- > arch/alpha/kernel/vmlinux.lds.S | 1 + > arch/m32r/kernel/vmlinux.lds.S | 1 + > arch/m68k/kernel/vmlinux-std.lds | 2 ++ > arch/m68k/kernel/vmlinux-sun3.lds | 1 + > arch/mips/kernel/vmlinux.lds.S | 1 + > arch/parisc/kernel/vmlinux.lds.S | 3 +++ > kernel/extable.c | 12 +++++++++++- > 7 files changed, 20 insertions(+), 1 deletion(-) Acked-by: Hirokazu Takata <takata@xxxxxxxxxxxxxx> Thank you. -- To unsubscribe from this list: send the line "unsubscribe linux-alpha" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
