  "message": "[ARM] 3101/1: ARM EABI: slab memory must be 64-bit aligned\n\nPatch from Nicolas Pitre\n\nAlthough ARM is still using 32-bit pointers, version 5 and later\nversions of the ARM architecture introduced the ldrd and strd\ninstructions to move 64-bit data which must be 64-bit aligned in memory,\nand the EABI includes new constraints on structure data alignment to\nallow for the compiler to use those instructions. This means that any\nslab allocation must start on a 64-bit boundary which is not equivalent\nto BYTES_PER_WORD, especially on those architecture versions that\nimplements the ldrd/strd instructions.\n\nOverriding the default alignment disables some slab debug features. If\nthose debug features are really needed then the kernel will have to be\ncompiled for version 4 of the ARM architecture.\n\nSigned-off-by: Nicolas Pitre \u003cnico@cam.org\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n",
