The patch titled
Switch Kprobes inline functions to __kprobes for ia64
has been removed from the -mm tree. Its filename is
switch-kprobes-inline-functions-to-__kprobes-for-ia64.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: Prasanna S Panchamukhi <prasanna@xxxxxxxxxx>
Andrew Morton pointed out that compiler might not inline the functions marked
for inline in kprobes. There by allowing the insertion of probes on these
kprobes routines, which might cause recursion. This patch removes all such
inline and adds them to kprobes section there by disallowing probes on all
such routines. Some of the routines can even still be inlined, since these
routines gets executed after the kprobes had done necessay setup for
reentrancy.
