Revision 0a3d31b79e7fa600108e699805e2b2f9ea1f3194 authored by Toshihiro HANAWA on 02 October 2009, 08:52:54 UTC, committed by Hirokazu Takata on 04 October 2009, 03:02:37 UTC
This patch fixes the m32r SMP kernel after 2.6.27.

A part of the following patch breaks m32r SMP operation.
> m32r: convert to generic helpers for IPI function calls
> commit 7b7426c8a615cf61df9a77b9df7d5b75d91e3fa0

In the above patch, a CALL_FUNC_SINGLE_IPI was newly introduced,
but the its IPI vector number was wrong in the patch code.

The m32r SMP kernel hanged-up during boot operation, because
the CPU_BOOT_IPI was called instead of CALL_FUNC_SINGLE_IPI
(CPU_BOOT_IPI had no side effect at that time because the 2nd
core had already been started up),
as a result, csd_unlock() was not called, then a dead lock
occurred in csd_lock_wait() after the detection of Compact Flash
memory as IDE generic disk.
