This patch uses an explicit word compare (cmpwi) and\nchanges the addic. to an addi (also changing \"\u003d\u0026r\" to \"\u003d\u0026b\" so that r0\nisn\u0027t used, and addi doesn\u0027t become li).\n\nThis also fixes a bug for both 32-bit and 64-bit in that previously\n0x80000000 was considered positive, since the result after\ndecrementing is positive.  Now it is considered negative.\n\nAlso, I clarify the return value in the comments just to make it clear\nthat the value returned is always the decremented value, even if that\nvalue is not stored back to the atomic counter.\n\nSigned-off-by: Robert Jennings \u003crcj@linux.vnet.ibm.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n"

      "message": "[PATCH] powerpc: Consolidate asm compatibility macros\n\nThis patch consolidates macros used to generate assembly for\ncompatibility across different CPUs or configs.  A new header,\nasm-powerpc/asm-compat.h contains the main compatibility macros.  It\nuses some preprocessor magic to make the macros suitable both for use\nin .S files, and in inline asm in .c files.  Headers (bitops.h,\nuaccess.h, atomic.h, bug.h) which had their own such compatibility\nmacros are changed to use asm-compat.h.\n\nppc_asm.h is now for use in .S files *only*, and a #error enforces\nthat.  As such, we\u0027re a lot more careless about namespace pollution\nhere than in asm-compat.h.\n\nWhile we\u0027re at it, this patch adds a call to the PPC405_ERR77 macro in\nfutex.h which should have had it already, but didn\u0027t.\n\nBuilt and booted on pSeries, Maple and iSeries (ARCH\u003dpowerpc).  Built\nfor 32-bit powermac (ARCH\u003dpowerpc) and Walnut (ARCH\u003dppc).\n\nSigned-off-by: David Gibson \u003cdwg@au1.ibm.com\u003e\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n"
