      "message": "Intel IOMMU: Avoid memory allocation failures in dma map api calls\n\nIntel IOMMU driver needs memory during DMA map calls to setup its internal\npage tables and for other data structures.  As we all know that these DMA map\ncalls are mostly called in the interrupt context or with the spinlock held by\nthe upper level drivers(network/storage drivers), so in order to avoid any\nmemory allocation failure due to low memory issues, this patch makes memory\nallocation by temporarily setting PF_MEMALLOC flags for the current task\nbefore making memory allocation calls.\n\nWe evaluated mempools as a backup when kmem_cache_alloc() fails\nand found that mempools are really not useful here because\n 1) We don\u0027t know for sure how much to reserve in advance\n 2) And mempools are not useful for GFP_ATOMIC case (as we call\n    memory alloc functions with GFP_ATOMIC)\n\n(akpm: point 2 is wrong...)\n\nWith PF_MEMALLOC flag set in the current-\u003eflags, the VM subsystem avoids any\nwatermark checks before allocating memory thus guarantee\u0027ing the memory till\nthe last free page.  Further, looking at the code in mm/page_alloc.c in\n__alloc_pages() function, looks like this flag is useful only in the\nnon-interrupt context.\n\nIf we are in the interrupt context and memory allocation in IOMMU driver fails\nfor some reason, then the DMA map api\u0027s will return failure and it is up to\nthe higher level drivers to retry.  Suppose, if upper level driver programs\nthe controller with the buggy DMA virtual address, the IOMMU will block that\nDMA transaction when that happens thus preventing any corruption to main\nmemory.\n\nSo far in our test scenario, we were unable to create any memory allocation\nfailure inside dma map api calls.\n\nSigned-off-by: Anil S Keshavamurthy \u003canil.s.keshavamurthy@intel.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Muli Ben-Yehuda \u003cmuli@il.ibm.com\u003e\nCc: \"Siddha, Suresh B\" \u003csuresh.b.siddha@intel.com\u003e\nCc: Arjan van de Ven \u003carjan@infradead.org\u003e\nCc: Ashok Raj \u003cashok.raj@intel.com\u003e\nCc: \"David S.
