  "message": "[IA64, X86_64] fix swiotlb sizing\n\n   Fix swiotlb sizing to match what the comments and the kernel\nparameters documentation indicate.  Given a default 16k page size kernel\n(ia64) and a 2k swiotlb page size, we\u0027re off by a multiple of 8 trying\nto size the swiotlb.  When specified on the boot line, the swiotlb is\nmade 8x bigger than requested.  When left to the default value, it\u0027s 8x\nsmaller than the comments indicate.  For x86_64 the multiplier would be\n2x.  The patch below fixes this.  Now, what\u0027s a good default swiotlb\nsize?  Apparently we don\u0027t really need 64MB.\n\nSigned-off-by: Alex Williamson \u003calex.williamson@hp.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n",
