  "message": "x86: Add support for lock prefix in alternatives\n\nThe current lock prefix UP/SMP alternative code doesn\u0027t allow\nLOCK_PREFIX to be used in alternatives code.\n\nThis patch solves the problem by adding a new LOCK_PREFIX_ALTERNATIVE_PATCH\nmacro that only records the lock prefix location but does not emit\nthe prefix.\n\nThe user of this macro can then start any alternative sequence with\n\"lock\" and have it UP/SMP patched.\n\nTo make this work, the UP/SMP alternative code is changed to do the\nlock/DS prefix switching only if the byte actually contains a lock or\nDS prefix.\n\nThus, if an alternative without the \"lock\" is selected, it will now do\nnothing instead of clobbering the code.\n\nChanges in v2:\n- Naming change\n- Change label to not conflict with alternatives\n\nSigned-off-by: Luca Barbieri \u003cluca@luca-barbieri.com\u003e\nLKML-Reference: \u003c1267005265-27958-2-git-send-email-luca@luca-barbieri.com\u003e\nSigned-off-by: H.
