sh: prefer _THIS_IP_ to current_text_addr

2018-08-17T23:20:27+00:00

As part of the effort to reduce the code duplication between _THIS_IP_
and current_text_addr(), let's consolidate callers of
current_text_addr() to use _THIS_IP_.

sh: Delete unnecessary checks before the function call "mempool_destroy"

2016-08-05T03:29:42+00:00

The mempool_destroy() function tests whether its argument is NULL
and then returns immediately. Thus the test around the calls is not needed.

This issue was detected by using the Coccinelle software.

arch/sh/kernel/dwarf.c: destroy mempools on cleanup

2015-04-14T23:48:56+00:00

dwarf_reg_pool and dwarf_frame_pool are not properly destroyed when
cleaning up the dwarf unwinder.  Destroy them with mempool_destroy().

Also mark dwarf_unwinder_cleanup() as __init.

arch/sh/kernel/dwarf.c: use rbtree postorder iteration helper instead of solution using repeated rb_erase()

Use rbtree_postorder_for_each_entry_safe() to destroy the rbtree instead
of using repeated rb_erase() calls

sh: handle early calls to return_address() when using dwarf unwinder.

2010-05-25T07:16:40+00:00

The dwarf unwinder ties in to an early initcall, but it's possible that
return_address() calls will be made prior to that. This implements some
additional error handling in to the dwarf unwinder as well as an exit
path in the return_address() case to bail out if the unwinder hasn't come
up yet.

This fixes a NULL pointer deref in early boot when mempool_alloc() blows
up on the not-yet-ready mempool via dwarf_unwind_stack().

sh: fix up the dwarf unwinder build for MODULES=n.

Presently the dwarf unwinder build blows up if modules are disabled,
fix it up.

sh: dwarf unwinder needs linux/module.h.

2010-04-20T05:34:15+00:00

Previously the struct module definition was pulled in from other headers,
but we want the reference to be explicit. Fixes up randconfig build
issues.
