  "message": "m32r: Fix IPI function calls for SMP\n\nThis patch fixes the m32r SMP kernel after 2.6.27.\n\nA part of the following patch breaks m32r SMP operation.\n\u003e m32r: convert to generic helpers for IPI function calls\n\u003e commit 7b7426c8a615cf61df9a77b9df7d5b75d91e3fa0\n\nIn the above patch, a CALL_FUNC_SINGLE_IPI was newly introduced,\nbut the its IPI vector number was wrong in the patch code.\n\nThe m32r SMP kernel hanged-up during boot operation, because\nthe CPU_BOOT_IPI was called instead of CALL_FUNC_SINGLE_IPI\n(CPU_BOOT_IPI had no side effect at that time because the 2nd\ncore had already been started up),\nas a result, csd_unlock() was not called, then a dead lock\noccurred in csd_lock_wait() after the detection of Compact Flash\nmemory as IDE generic disk.\n\nSigned-off-by: Toshihiro HANAWA \u003chanawa@ccs.tsukuba.ac.jp\u003e\nSigned-off-by: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\n",
