2007-04-30Extend print_symbol capabilityRobert Peterson
Today's print_symbol function dumps a kernel symbol with printk. This patch extends the functionality of kallsyms.c so that the symbol lookup function may be used without the printk. This is useful for modules that want to dump symbols elsewhere, for example, to debugfs. I intend to use the new function call in the GFS2 file system (which will be a separate patch).

2006-10-03[PATCH] Create kallsyms_lookup_size_offset()Franck Bui-Huu
Some uses of kallsyms_lookup() do not need to find out the name of a symbol and its module's name it belongs. This is specially true in arch specific code, which needs to unwind the stack to show the back trace during oops (mips is an example). In this specific case, we just need to retreive the function's size and the offset of the active intruction inside it. Adds a new entry "kallsyms_lookup_size_offset()" This new entry does exactly the same as kallsyms_lookup() but does not require any buffers to store any names. It returns 0 if it fails otherwise 1.

2006-07-03[PATCH] lockdep: add print_ip_sym()Heiko Carstens
Provide a common print_ip_sym() function that prints the passed instruction pointer as well as the symbol belonging to it. Avoids adding a bunch of #ifdef CONFIG_64BIT in order to get the printk format right on 32/64 bit platforms.

2006-07-03[PATCH] lockdep: special s390 print_symbol() versionHeiko Carstens
Have a special version of print_symbol() for s390 which clears the most significant bit of addr before calling __print_symbol(). This seems to be better than checking/changing each place in the kernel that saves an instruction pointer. Without this the output would look like: hardirqs last enabled at (30907): [<80018c6a>] 0x80018c6a hardirqs last disabled at (30908): [<8001e48c>] 0x8001e48c softirqs last enabled at (30904): [<8001dc96>] 0x8001dc96 softirqs last disabled at (30897): [<8001dc50>] 0x8001dc50 instead of this: hardirqs last enabled at (19421): [<80018c72>] cpu_idle+0x176/0x1c4 hardirqs last disabled at (19422): [<8001e494>] io_no_vtime+0xa/0x1a softirqs last enabled at (19418): [<8001dc9e>] do_softirq+0xa6/0xe8 softirqs last disabled at (19411): [<8001dc58>] do_softirq+0x60/0xe8 Acked-by: Ingo Molnar <mingo@elte.hu> Cc: Arjan van de Ven <arjan@infradead.org> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
