Subject: Re: [uml-devel] [patch 06/37] UML - Fix static linking

I have one objection, the fix has a typo! This is the additional fix 
(note '.note' instead of 'note'):

--- linux-2.6.git.orig/include/asm-um/common.lds.S
+++ linux-2.6.git/include/asm-um/common.lds.S
@@ -15,7 +15,7 @@
   PROVIDE (_unprotected_end = .);

   . = ALIGN(4096);
-  .note : { *(note.*) }
+  .note : { *(.note.*) }
   __start___ex_table = .;
   __ex_table : { *(__ex_table) }
   __stop___ex_table = .;

With this, the fix should be merged - I just re-hit this bug and rechecked 
everything, now it's ok.
