parisc: initialize unwinder much earlier

2008-10-10T16:32:30Z

The unwinder was being initialized way too late to be any use debugging early boot crashes. Instead of relying on module_init initcalls to initialize it, let's do it explicitly as early as we can. Signed-off-by: James Bottomley Signed-off-by: Kyle McMartin

kallsyms: make KSYM_NAME_LEN include space for trailing '\0'

2007-07-17T17:23:03Z

KSYM_NAME_LEN is peculiar in that it does not include the space for the trailing '\0', forcing all users to use KSYM_NAME_LEN + 1 when allocating buffer. This is nonsense and error-prone. Moreover, when the caller forgets that it's very likely to subtly bite back by corrupting the stack because the last position of the buffer is always cleared to zero. This patch increments KSYM_NAME_LEN by one and updates code accordingly. * off-by-one bug in asm-powerpc/kprobes.h::kprobe_lookup_name() macro is fixed. * Where MODULE_NAME_LEN and KSYM_NAME_LEN were used together, MODULE_NAME_LEN was treated as if it didn't include space for the trailing '\0'. Fix it. Signed-off-by: Tejun Heo Acked-by: Paulo Marques Cc: Benjamin Herrenschmidt Cc: Paul Mackerras Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PARISC] unwinder improvements

2007-06-21T21:46:22Z

Add special-case handling for "handle_interruption" so that we can rewind past the interruption. This is useful for seeing what caused a BUG() or WARN_ON(); otherwise the unwind stops at the interruption. Signed-off-by: Randolph Chung Signed-off-by: Kyle McMartin

[PARISC] Fix unwinder on 64-bit kernels

2007-06-21T21:46:21Z

The unwinder was broken by the shift of PAGE_OFFSET in order to increase the size of the vmalloc area on 64-bit kernels. Signed-off-by: Randolph Chung Signed-off-by: Kyle McMartin

[PARISC] fix null ptr deref in unwind.c

2007-05-30T06:24:28Z

commit ffb45122766db220d0bf3d01848d575fbbcb6430 removed one too many args. kallsyms_lookup is not safe to call with a NULL *modname. Paper bag over the problem for the time being. Signed-off-by: Kyle McMartin

Simplify kallsyms_lookup()

2007-05-08T18:15:08Z

Several kallsyms_lookup() pass dummy arguments but only need, say, module's name. Make kallsyms_lookup() accept NULLs where possible. Also, makes picture clearer about what interfaces are needed for all symbol resolving business.

[PARISC] Remove sched.h from uaccess.h on parisc

2007-02-17T05:44:30Z

Al Viro did this for x86-64 and reduced the number of dependencies on sched.h significantly. We had a couple of files which were relying on uaccess.h pulling in sched.h, so they need explicit dependencies added. Signed-off-by: Matthew Wilcox Signed-off-by: Kyle McMartin

[PATCH] getting rid of all casts of k[cmz]alloc() calls

2006-12-13T17:05:58Z

Run this: #!/bin/sh for f in $(grep -Erl "$[^$]*\) *k[cmz]alloc" *) ; do echo "De-casting $f..." perl -pi -e "s/ ?= ?$[^$]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f done And then go through and reinstate those cases where code is casting pointers to non-pointers. And then drop a few hunks which conflicted with outstanding work.
