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.
