The patch titled
Switch Kprobes inline functions to __kprobes for sparc64
has been removed from the -mm tree. Its filename is
switch-kprobes-inline-functions-to-__kprobes-for-sparc64.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.
