The patch titled
Let smp_call_function_single return -EBUSY on UP
has been removed from the -mm tree. Its filename was
let-smp_call_function_single-return-ebusy-on-up.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Let smp_call_function_single return -EBUSY on UP
From: Heiko Carstens <[EMAIL PROTECTED]>
All architectures that have an implementation of smp_call_function_single
let it return -EBUSY if it is asked to execute func on the current cpu.
(akpm: except for x86_64). Therefore the UP version must always return
-EBUSY.
