The patch titled
Subject: kernel: rename show_stack_loglvl() => show_stack()
has been removed from the -mm tree. Its filename was
kernel-rename-show_stack_loglvl-=-show_stack.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Dmitry Safonov <dima@xxxxxxxxxx>
Subject: kernel: rename show_stack_loglvl() => show_stack()
Now the last users of show_stack() got converted to use an explicit log
level, show_stack_loglvl() can drop it's redundant suffix and become once
again well known show_stack().
